Various types of metal heat treatment furnaces (quenching, annealing, homogenizing, carburizing), pipe continuous furnaces (for stainless steel, copper, aluminum, etc.), aluminum melting and holding furnaces, brazing furnaces, and more.
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."

Company information
Since its founding in 1891, we have progressed as a manufacturer specializing in refractory materials and continue to produce refractory bricks and insulators for electric furnaces. Our main products today are industrial electric heaters, and we excel in the design and manufacturing of heaters for electric furnaces that operate in harsh environments with extreme temperature fluctuations, creating them to order. Using metal heating elements, we provide electric furnace heaters that can withstand temperatures up to 1200°C, which are used in furnaces for processes such as carburizing and quenching of iron, as well as bending glass. Additionally, as a new product, we have successfully developed and commercialized a hot air generation device by combining metal heating element processing technology with ceramic insulator manufacturing technology. Our motto is to thoroughly address our customers' concerns and challenges and to stay with them until solutions are found. Based on the technology and know-how cultivated over more than 125 years of history and achievements, we are ready to assist with any inquiries related to heat.
