What is batch annealing process?

Batch annealing is an advanced process in which metal materials are heat-treated by precisely controlling the temperature and protective atmosphere in a sealed bell jar. The material is heated to a specified temperature in an oxygen-free environment, kept warm, and then slowly cooled. The entire process usually takes tens to hundreds of hours.

Five core advantages

No oxidation on the surface: the protective atmosphere environment ensures that the surface of the material is smooth and clean, with no oxidized decarburization.

Super uniform temperature: closed heating to ensure that the temperature of the entire batch of material is consistent, stable product performance.

Controllable process: automated control system, precise parameters, reliable quality.

Full coverage of specifications: from thin plates to thick plates, various specifications of materials can be processed.

Energy saving and environmental protection: Compared with the traditional process, energy consumption is reduced by 20% and emissions by 30%.

Application areas

is mainly used for the production of high-quality cold-rolled steel plate, electrical steel sheet, stainless steel plate and other precision materials, widely serving the automotive, home appliances, precision instruments and other high-end manufacturing industries.
