Flame hardening

Flame hardening

Local heating for processing complex shapes. Suitable for small-batch production of various types.

By applying high-temperature flames such as oxy-acetylene flames to locally heat the surface of steel parts, it is less affected by the shape of the workpiece. Skilled craftsmen accurately control the temperature using the color of the flame. Additionally, it is economical because it does not require fixtures or coils like high-frequency heat treatment (quenching) for the same localized heating process. ● It is used for processing complex machined parts that cannot be handled by high-frequency quenching. ● We conduct thorough prior discussions and perform heat treatment suitable for the material. ● It is economical because it does not require the cost of manufacturing special fixtures.

Introduction to Heat Treatment: A Beginner's Guide from the Basics

Introduction to Heat Treatment: A Beginner's Guide from the Basics

[Functional and Property Improvement] Basic Knowledge of Heat Treatment Used in Automotive Parts and Aircraft Parts

Heat treatment refers to a metal processing technique aimed at improving the properties of metallic materials. The heat treatment process involves heating, holding, and cooling components or materials, which changes their characteristics. Why is heat treatment necessary? Metallic materials have the property of being brittle as they become harder. They are strong against deformation, but when a certain amount of force is applied, they can suddenly break or crack. It is common to apply heat treatment to improve the properties of metallic materials. We are currently offering a beginner's booklet that provides basic knowledge about heat treatment as a gift. *For more details, please refer to the PDF document or feel free to contact us.*

[Metal Heat Treatment Guide] What is Annealing?

[Metal Heat Treatment Guide] What is Annealing?

Introducing "tempering," which increases strength and ductility and is also used as a preliminary treatment for quenching.

"Annealing" is a heat treatment that removes internal stresses caused by processing, restores the structure to a standard state, and refines it. By performing annealing, strength and ductility are increased, making it useful as a preliminary treatment for quenching. Additionally, steel is held in the austenite structure for a sufficient period and then cooled adequately in air. 【What is Annealing】 ■ Removes internal stresses caused by processing ■ Restores the structure to a standard state or refines it ■ Steel is held in the austenite structure for a sufficient period and then adequately cooled in air *For more details, please refer to the PDF document or feel free to contact us.

Electric heating elements for industrial furnaces, used in metal heat treatment, electronic components, and chemical industry applications!

Electric heating elements for industrial furnaces, used in metal heat treatment, electronic components, and chemical industry applications!

Manufacturing heaters suitable for electric furnaces with an internal temperature of up to 1200℃!

A metal heating element refers to a type of resistance heating element among general heating sources. Electric heating elements for industrial furnaces that include this metal heating element are used in various industries such as metal heat treatment, electronic components, ceramics, and chemical industries. Our company manufactures electric furnace heaters suitable for furnace temperatures up to 1200°C using iron-chromium-aluminum alloy (FeCrAl), which is a type of metal heating element. The shapes of metal heating elements vary. Here, we introduce some of the products we handle. 1. Round wire coil heating element This is a heating element made by spirally winding round wire. The wire diameter and outer coil diameter are set according to the heater's capacity and temperature. 2. Strip heating element A zigzag-shaped circuit is formed by alternately slitting plate-like material. By adjusting the slit width, the resistance value of the heating element is changed, allowing for precise design of heater output. Additionally, we perform concave processing calculated to suppress deformation due to thermal expansion of the heating element. This technology has been developed uniquely by our company.
