>R & D>Core Technology

HT: heat treatment process is strictly controlled in our HT plant with temperature uniformity and regular

calibration of the thermocouple. The quenching tank has enough space to handle common products, and

the bottom of the tank is equipped with a mixing device and connected with an  external cooling tower.

The temperature of the quenching medium is strictly controlled by the temperature alarm device, which

ensures that the quenching material obtains enough cooling. The use of mechanical hand greatly reduces

the time from the furnace to the quenching tank.  We are strictly in accordance with the corresponding

materials technology for heat treatment,  and provide the corresponding heat treatment curve and heat

treatment report per the smelting furnace number and heat treatment lot number.
