Box type vacuum muffle furnace is widely used in the metal industry, specifically reflected in the following aspects:

Metal heat treatment:

Annealing treatment: Box type vacuum muffle furnace is used for annealing metal materials, which can reduce the hardness of metal materials, improve their plasticity and toughness, and prepare for subsequent cold processing or heat treatment.

Quenching and tempering: By precisely controlling the heating and cooling processes, the box type vacuum muffle furnace can achieve quenching and tempering treatment of metal materials, improve the hardness and wear resistance of metals, eliminate quenching stress, and stabilize the structure and size.

Metal sintering:

Powder metallurgy: In the field of powder metallurgy, a box type vacuum muffle furnace is used for the sintering process of metal powders, which enables the bonding between metal particles and improves the density and strength of materials.

Hard alloy preparation: The box type vacuum muffle furnace can be used for vacuum sintering of hard alloy cutting tools and other products, significantly improving the hardness and wear resistance of the products.

Metal melting and purification:

Vacuum melting: Metal melting is carried out in a vacuum environment, which can avoid the reaction between metal and oxygen, nitrogen, etc. in the air, thereby obtaining high-purity metal or alloy.

Metal purification: Through vacuum melting and refining processes, the box type vacuum muffle furnace can be used for metal purification, removing impurity elements and improving the purity of metals.

Metal surface treatment:

Surface modification: Box type vacuum muffle furnace can be used for carburizing, nitriding and other treatments on metal surfaces, changing the chemical composition and microstructure of the metal surface, improving the wear resistance, corrosion resistance and fatigue strength of the metal.

Vacuum coating: In a vacuum environment, the box type vacuum muffle furnace can also be used for coating treatment on metal surfaces, such as titanium plating, chrome plating, etc., to enhance the beauty and durability of metals.

Research and development of metal materials:

New material synthesis: In the field of new material research and development, the box type vacuum muffle furnace can be used for high-temperature synthesis of metal materials or alloys with special properties.

Performance testing: Through heat treatment experiments on metal materials in a vacuum environment, the box type vacuum muffle furnace can also be used to evaluate the thermal stability, oxidation resistance, and other properties of materials.
