戸畑製作所 List of Products and Services

We would like to introduce our "pure copper products for blast furnaces," which are suitable for use in high-temperature environments where cooling capacity is required. The "tuya" is a product used to blow hot air into the blast furnace, while the "cooling plate" cools the refractory bricks stacked on the inner walls of the furnace, helping to reduce wear. Additionally, we offer wear-resistant and erosion-resistant overlay materials. 【Product Lineup】 ■ Tuya ・ Hardened overlay material ■ Daimaru (tuya holder, cutting tool) ■ Cooling plate *For more details, please refer to the PDF document or feel free to contact us.

"Diffusion bonding" is a method that involves cleaning the surfaces to be joined, heating the materials above the recrystallization temperature in a high vacuum or inert atmosphere, and applying a relatively small pressure to achieve bonding through atomic diffusion between the materials. This method results in minimal deformation during bonding, making it suitable for joining precision components. Additionally, it allows for surface bonding and layering. Please feel free to contact us when you need our services. 【Features】 ■ Capable of joining dissimilar metals ■ Capable of manufacturing hollow components ■ Minimal deformation during bonding, suitable for precision component joining ■ Surface bonding and layering are possible *For more details, please refer to the PDF materials or feel free to contact us.
