Quenching. The quenching heating temperature of hypoeutectoid steel (low and medium carbon steel) with carbon content less than 0.8% is 30 ~ 50 ℃ above A3 line. At this temperature

In the processing process, gear forgings need heat treatment to achieve the desired performance requirements through manual heating, insulation and cooling. Generally, the heat treatment methods of gear forgings are as follows.

The function of heat treatment is to improve the mechanical properties of materials, eliminate residual stress and improve the machinability of metals. According to different purposes of heat treatment

The ratio of the surface temperature (average temperature for short) and the central temperature (insulation) of the forging to the total heating time varies with the heating temperature.

Common heat-resistant steels need to be cast under high temperature conditions, so they need sufficient anti-oxidation, corrosion and wear resistance. If there is segregation in product material or quality

On April 24, 2018, Dr. Yang and his delegation from North American GM visited Chongqing Fengdong Heat Treatment Engineering Co., Ltd.

The well vacuum furnace control system selects the temperature control thermocouple and Shanghai Guolong intelligent digital display temperature control instrument for temperature control.

In order to facilitate the heating of large workpieces, a trolley furnace suitable for heating ingots and large billets is presented, and a well furnace is also presented for heating long rods. After the 1920s, various mechanized and active furnace types that can improve furnace productivity and improve working conditions were presented.

The box type quenching furnace, also known as hard die forging or permanent die forging, is a method to pour the melted aluminum alloy into the metal mold to obtain castings.

Box quenching furnace is a periodic operation furnace, which is suitable for the heat treatment of rod and long shaft parts. The structure of the box quenching furnace is: the furnace body is a cylindrical deep well, and the workpieces are vertically loaded into the furnace for heating by a special crane.
