Application of Box type High temperature Resistance Furnace in the Metal Industry

Box type high-temperature resistance furnaces are mainly used in the metal industry for heat treatment of metal materials, powder metallurgy, and brazing of metal products. The following is a specific introduction:

Heat treatment of metal materials
Annealing treatment: By heating the metal material to an appropriate temperature and holding it for a certain period of time, and then slowly cooling it, residual stresses inside the metal material are eliminated, hardness is reduced, toughness and plasticity are improved, and the processing performance of the metal is improved. For example, in steel production, for cold-rolled steel plates, cold drawn steel wires, etc., annealing treatment is often used to eliminate work hardening, restore the plasticity and toughness of the material, and facilitate subsequent processing and use.
Quenching treatment: Heating the metal material above the critical temperature, holding it for an appropriate period of time, and then rapidly cooling it to obtain a high hardness and high strength structure. For example, in mold manufacturing, quenching the mold steel can improve the hardness, wear resistance, and thermal fatigue performance of the mold, thereby increasing the service life and work efficiency of the mold.
Tempering treatment: usually carried out after quenching, heating the quenched metal material to a certain temperature range below the critical temperature, holding for a certain period of time, and then cooling. Its purpose is to eliminate quenching internal stress, reduce material brittleness, adjust the balance between hardness and toughness, and enable metal materials to obtain good comprehensive mechanical properties. For example, for some metal parts that withstand impact loads, such as gears, shafts, etc., after quenching and tempering treatment, the surface hardness and wear resistance can be guaranteed, while also having sufficient toughness to withstand impact.

Powder metallurgy
Powder sintering: Pressing metal powder or a mixture of metal and non-metal powders into the desired shape of the body, and then sintering it in a box type high-temperature resistance furnace. At high temperatures, diffusion and fusion processes occur between powder particles, resulting in densification of the green body and obtaining a sintered body with certain strength and properties. For example, in the manufacturing of mechanical parts, hard alloy cutting tools, etc., powder metallurgy technology has the advantages of high material utilization, high production efficiency, and the ability to manufacture complex shaped parts. The precise temperature control and uniform temperature distribution of the box type high-temperature resistance furnace provide good conditions for powder sintering, ensuring the quality and performance of the sintered body.

Metal product brazing
Brazing heating: Using a brazing material with a lower melting point than the base material, when heated to a temperature higher than the melting point of the brazing material but lower than the melting point of the base material, the brazing material melts and wets the surface of the base material, filling the joint gap through diffusion to achieve the connection of metal products. The box type high-temperature resistance furnace can provide a stable heating environment, accurately control the brazing temperature, ensure uniform melting of the brazing material and good wetting effect, thereby obtaining high-quality brazed joints. For example, in the manufacturing of electronic devices, some metal components are often connected using brazing technology. Box type high-temperature resistance furnaces can be used to solder the pins of small electronic components to circuit boards, ensuring the reliability and conductivity of the connection.
