Zhengzhou Kejia Furnace Co., Ltd. is a high-tech enterprise specializing in the development, production and sales of heat treatment products. It is the responsibility of every Kejia person to provide reasonable furnace solutions and efficient service! The
Box furnaces are mainly used for heat treatment such as normalizing, quenching and annealing of alloy steel products, various metal parts, or for high-temperature sintering of cutting blades such as diamond. During the heating process, sometimes the heate
Box-type resistance furnaces and pit-type resistance furnaces have some common features. Most of the internal heating types are made of refractory materials and thermal insulation materials. The internal atmosphere is mostly air under normal pressure, but
In the heat treatment industry, the heat treatment of some workpieces needs to be carried out under the protection of inert gas to achieve a certain purpose of heat treatment, such as gas carburizing, carbonitriding and bright quenching, annealing, normal
In March 2022, Zhengzhou Kejia Electric Furnace Co., Ltd. newly purchased a 1,500-square-meter industrial plant park in Zhengzhou Equipment Industrial Park, where tradition and innovation blend. The handover and kick-off ceremony of the production base of
When vacuum annealing stainless steel, if the process is not up to standard, it is easy to cause the product to turn blue after heat treatment. The following briefly introduces the reasons and solutions for this problem:
Vacuum brazing furnaces are mainly used for stainless steel, copper, titanium alloys, superalloys, hard alloys, diamond tools, thermos cups (pots), aluminum radiators, air conditioner evaporators, condensers, radar grid antennas, waveguides, etc. Vacuum b
Rotary tube furnaces are widely used in laboratories and small batch production. They can be tilted and rotated to make the heating of materials more uniform. They can also be designed as rotary tube furnaces with automatic feeding and discharging. They a
Deposition temperature in CVD technology, total flow and total pressure of mixed gas entering the reaction chamber, partial pressure of each gas phase component in the mixed gas and their relative proportions, deposition time, nature, shape of the substra
Tube furnaces are mainly used in metallurgy, glass, heat treatment, lithium battery anode and cathode materials, new energy, abrasive tools and other industries, and are professional equipment for measuring materials under certain temperature conditions.
