Products from Teitokusha can undergo a full model change, but there are also many opportunities for minor changes through a slight shift in perspective while cherishing the items you are currently using. I would like to introduce a few examples of what we are actually doing. I would be happy if you could share this with everyone in your department and related parties. ■ Improvement of Heating Element Arrangement This is a proposal using ceramic fiber, but due to the thermal characteristics, the lower side inevitably becomes low temperature. Therefore, I proposed an arrangement that collects heat at the bottom. Additionally, it is possible to adjust the thermal capacity by widening or narrowing the coil winding pitch. ■ Heater Uniformity Testing To achieve uniform temperature distribution for heat treatment heaters manufactured for the automotive industry, we are conducting optimization verification tests on workpiece placement, circuit separation, and output adjustments. There are many things that can be realized by making slight improvements while keeping the core intact. I hope that among our customers, there are those who think, "We have been struggling with this too. Let's consult about it."

[Testing Examples] 1. Glass Fiber Organic Residue Test In the production of glass fibers, it is essential to burn off the organic materials in a drying oven. However, there was interest in whether it could be effectively burned off using our hot air generation equipment. After several discussions, an opportunity arose for a company visit, during which we operated the equipment as part of a factory tour and conducted a simple pattern test. If you contact us in advance, it is possible to check the availability of the equipment and conduct a simple test. 2. Surface Temperature Comparison Test Under High-Temperature Atmosphere In the equipment used by the customer, there is a risk of electric leakage when the surface temperature of the heater becomes high. Therefore, the specifications were changed to enhance the heat dissipation effect, and both old and new heaters were tested under the same conditions to measure and compare their surface temperatures. The results showed that by enhancing the heat dissipation effect, there was a tendency for the surface temperature of the heater to decrease. This time, due to temperature differences depending on the measurement method, it is necessary to consider new challenges regarding measurement methods in relation to actual furnace measurements, and we are currently working on this.

The RCF regulation aims to strengthen measures to prevent health hazards for workers related to refractory ceramic fibers (insulation materials). It was enacted and applied in November 2015 as a "Cabinet Order to partially amend the Enforcement Order of the Industrial Safety and Health Act" and as a "Ministry Ordinance to partially amend the Industrial Safety and Health Regulations." As a result of this amendment, it has been classified as a Class 2 substance of specified chemical substances and is subject to preventive regulations. Please note that special protective measures are required when processing, etc. (There are no issues if no cutting or processing is done.) Additionally, there are regulations regarding labeling on containers and packaging, the provision of documents (SDS), the maintenance of the working environment, and notifications. However, if the specified preventive measures are taken, RCF can be used safely. Our company has designated the conventional boards as "RCF regulated products" and continues to handle them. We also offer RCF regulation-compliant products and environmentally friendly specifications (Non-RCF), including alumina fiber boards and bio-soluble fiber boards.

The ceramic fiber heaters from Teitokusha are manufactured by combining our unique heating element processing technology, ceramics technology that leverages know-how from 100 years of refractory brick manufacturing, and processing technology for ceramic fiber boards. 【Heating Element】 We primarily use round wire coil heating elements that are wound into a coil shape. Our company processes strip-shaped heating elements with slits, adjusting the slit width to design them according to the customer's requirements for current and voltage. 【Ceramics】 The essential function required for ceramics used in heaters is thermal shock resistance. Since the heating element becomes hot immediately upon applying electricity, ceramics that can withstand this rapid temperature change are necessary. We design and manufacture ceramics in-house with formulations tailored to the usage conditions. 【Ceramic Fiber Board Processing Technology】 We perform processing of heaters to the dimensions and shapes requested by our customers. Instead of leaving the ceramic fiber board as is, we also accept various processing treatments such as surface effect treatment, binder removal, and lamination. We will solve your problems with products that combine these technologies!

Do you know about the Platinum Reflector? As the name suggests, it is a "platinum reflector." The Platinum Reflector is made by applying a platinum film onto a heat-resistant alloy, and it can be used in an atmosphere of 800°C. While conventional heat-resistant alloy reflectors were limited to a maximum usage of 500°C, by coating the surface with a thin film of platinum, we have achieved high heat resistance of 800°C. **Features of the Platinum Reflector:** 1. **Heat resistance of 800°C for regular use** By using special materials to prevent the reaction of components in the intermediate layer of platinum and heat-resistant metals, heat resistance of 800°C for regular use is achievable. 2. **Cost-effective** By using platinum foil, it becomes cheaper than vapor deposition or plating processes, achieving low costs. 3. **Delicate temperature distribution** It is very effective in creating the desired temperature distribution because it can be made directional. 4. **Impact-resistant structure** Since the reflective film is on a heat-resistant metal substrate, it has a structure that is more resistant to impact compared to conventional reflectors on quartz glass.

What is a hot air generator? Where is it used? I believe some of you may have such questions. Our hot air generator is electric, takes in air, and outputs air at 1000°C with a flow rate of 1Nm³ from the outlet. As for where hot air generators are used, they are utilized in various applications such as: - Drying processes for workpieces - Heat treatment and thermal processing of workpieces - Heat retention processes for workpieces The development of the N2 1100°C and Air 1200°C models was prompted by requests from our customers. Previously, the maximum temperatures were N2 900°C and Air 1000°C. Among these, achieving a high temperature of 1000°C with a large flow rate of 1Nm³ simultaneously was quite rare, but we received inquiries asking, "Can we achieve 1000°C with N2?" As a result of development efforts by our design and technical departments, we were able to achieve N2 1100°C and Air 1200°C by adding optional components to the conventional hot air generator, exceeding our customers' requested temperatures.

This time, we would like to introduce heaters that utilize "far infrared rays," which are a type of "infrared" with longer wavelengths. Objects emit energy in the form of electromagnetic waves (light) according to their temperature. The higher the object's temperature, the greater the total amount of electromagnetic waves emitted, but the peak wavelength of the emitted waves becomes shorter. Electromagnetic waves in the far infrared range (3μm to 25μm) are generally said to be easily absorbed by materials, allowing for efficient heating of objects. Therefore, we have developed a paint (far infrared paint) that emits a large amount of electromagnetic waves in the far infrared range by applying our ceramic raw material formulation technology. Transparent materials like glass tend to allow electromagnetic waves to pass through easily, which means that heat from the heating element does not sufficiently transfer to the object being heated. As a result, if a lot of heater power is applied, electricity costs can increase. To address this, we can apply wavelength conversion paint to convert the waves to wavelengths that glass absorbs easily, allowing for efficient heat transfer to the object being heated without passing through. Effects of applying far infrared paint: - The load on the heater decreases, allowing for longer usage. - It has energy-saving effects since unnecessary energy is not used. - The heating speed increases, improving efficiency.

A ceramic fiber heater is something that some of you may already know about, but here are some specific applications: - Various metal heat treatment furnaces (quenching, annealing, homogenizing, carburizing) - Pipe continuous furnace treatment (stainless steel, copper, aluminum, etc.) - Aluminum melting and holding furnaces - Brazing furnaces - Ceramic sintering furnaces - Diffusion furnaces for semiconductors - CVD furnaces - Continuous processing furnaces for low-voltage and electronic applications - Ceramic firing furnaces - Glass heat treatment furnaces Most of these use round wire heating elements coiled into shape, but Seidokusha also manufactures heaters using strip-type heating elements. The advantages of strip-type heating elements include: - By covering the entire area of the insulation material with heating elements, uniform heat treatment can be achieved. - Compared to heaters using round wire coil heating elements, more than double the wattage can be applied. This is recommended for customers who want to "increase capacity in the same area," "eliminate temperature variations (improve uniformity)," or "increase heating speed."

What kind of image do you have of a hot air generator? The common household image is that of a hair dryer. As the name suggests, it is a machine that produces hot air! As a hot air generator, it can simultaneously achieve a high temperature of 1000°C and a flow rate of 1 Nm³. So, where can hot air generators be used? - Drying processes for workpieces - Heat treatment and thermal processing of workpieces - Heat retention processes for workpieces They can be used in various applications. For those who are already using hot air generators, do you have any of the following concerns? "I want more airflow even though the temperature is high." "I have enough flow, but I wish the temperature were a bit higher." "I want to direct the airflow downwards instead of sideways." If so, please try the hot air generator from Teitokusha. Currently, for those using gas and facing concerns such as: "I can't use combustion gases." "The piping is extensive and cumbersome." "I want to improve the factory environment." It can also be used as an electric replacement. Additionally, with an outlet temperature of 1000°C, it can handle high temperatures even at the workpiece's contact point. We also offer control panels as an option.

A metal frame heater is a heater that uses metal in its frame, designed for rapid temperature rise and fall with a low heat capacity. "I want to use it in a clean environment." "I want temperature control." "I want uniform heat distribution over a wide area." This product is recommended for such customers. The metal frame heater has the following features: - By using metal in the frame, it has a lower heat capacity than ceramic fiber heaters, allowing for a reduction in heat processing time. (The temperature rise and fall speed has been shortened by 50-60% compared to ceramic fiber heaters.) - The heating element is suspended, allowing the heat from the back to be utilized as radiant heat. - By combining it with our specialty strip heating elements, effective use of the heating surface is achieved. Additionally, it can be freely designed at any angle you prefer. Repairs and upgrades through part replacements are also possible. We offer many options as well. Please feel free to consult with us.
