Application fields of box type high-temperature resistance furnace

The box type high-temperature resistance furnace has the characteristics of precise temperature control, easy operation, and wide applicability, and is widely used in the following fields:

Heat treatment of metal materials
Quenching: By heating metal materials above the critical temperature, holding them for a certain period of time, and then rapidly cooling them, the hardness, strength, and wear resistance of the metal can be improved. For example, quenching mold steel can achieve higher hardness and wear resistance, extending the service life of the mold.
Tempering: usually carried out after quenching, heating the metal material to a temperature range below the critical temperature, holding for a certain period of time, and then cooling, can eliminate quenching stress, stabilize the structure and size, and improve the toughness of the material. Tempering quenched spring steel can improve its toughness and elasticity while maintaining high strength.
Normalization: Heating metal materials above the critical temperature, holding them for an appropriate period of time, and then cooling them in air can refine the grain size, improve the strength and toughness of the material, and is commonly used to improve the cutting performance of low carbon steel and medium carbon steel.
Annealing: Heating a metal material to an appropriate temperature, holding it for a certain period of time, and then slowly cooling it to reduce its hardness, improve its plasticity, eliminate internal stress, and improve its structure. For example, annealing the metal material after cold deformation can restore its plasticity and facilitate further processing.

Ceramic material sintering
Traditional ceramic preparation: In the production of traditional ceramic products such as daily-use ceramics and architectural ceramics, a box type high-temperature resistance furnace is used to heat the ceramic body to a high temperature, causing it to undergo sintering reaction, improving the density, strength, and hardness of the ceramic, and enhancing its performance and appearance quality. For example, placing the green body of ceramic tableware into a box type high-temperature resistance furnace and sintering it at a high temperature of around 1200 ℃ -1400 ℃ makes it dense, hard, and has good corrosion resistance and thermal stability.
Preparation of special ceramics: For high-performance special ceramics such as alumina ceramics, silicon nitride ceramics, silicon carbide ceramics, etc., box type high-temperature resistance furnaces are indispensable equipment. By precisely controlling process parameters such as sintering temperature and atmosphere, ceramic materials with special properties can be prepared and widely used in fields such as aerospace, electronics, and machinery. For example, when preparing silicon nitride ceramic cutting tools, high-temperature sintering is required in a high-temperature resistance furnace to obtain tool materials with high hardness, strength, and good wear resistance.

Powder metallurgy
Sintering of powder pressed body: The pressed powder metallurgy body is placed in a box type high-temperature resistance furnace for sintering. At high temperatures, diffusion and fusion processes occur between powder particles, making the body denser, improving strength and hardness, and obtaining the desired shape and properties. For example, in the production of automotive engine components such as gears and sprockets, powder metallurgy technology is used to prepare blanks, which are then sintered in a box type high-temperature resistance furnace to improve the accuracy and performance of the components while reducing production costs.
Processing of metal powder: The box type high-temperature resistance furnace can also be used for pre-treatment of metal powder, such as removing impurities and oxides on the surface of the powder, improving the purity and activity of the powder, and facilitating subsequent pressing and sintering processes.

Preparation of electronic materials
Annealing of semiconductor materials: In the manufacturing process of semiconductor chips, it is necessary to anneal semiconductor materials such as silicon wafers to eliminate lattice defects and improve impurity distribution. The box type high-temperature resistance furnace provides a precisely controlled high-temperature environment, which can meet the requirements of semiconductor material annealing process and improve the performance and reliability of chips.
Preparation of electronic ceramics: For electronic ceramic materials such as barium titanate ceramics, zinc oxide pressure-sensitive ceramics, etc., a box type high-temperature resistance furnace is used for their sintering process to obtain ceramic materials with good dielectric, piezoelectric or pressure-sensitive properties, which are widely used in the manufacturing of electronic components. For example, in the production of multi-layer ceramic capacitors, it is necessary to press and shape barium titanate ceramic powder, and then sinter it into a ceramic dielectric with high dielectric constant in a high-temperature resistance furnace to improve the performance of the capacitor.
