Annealing furnace quality appraisal

annealing furnace is a device used to heat and anneal metal materials. Annealing refers to heating a metal material to a certain temperature and then slowly cooling it to change its crystal structure, reduce internal stress, and improve its plasticity and toughness.
In the case of annealing furnace quality appraisal, Zhongke Testing can provide annealing furnace quality appraisal services.

There was a quality problem with the mesh belt-type electric dual-purpose baking annealing furnace purchased by a heavy industry company, which caused the glass products to burst, resulting in a dispute with the equipment manufacturer.
was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" in the annealing furnace involved.
appraisal analysis results: The
appraisal analysis expert group discussed the relevant information and on-site investigation of the annealing furnace involved and made a comprehensive quality technical analysis, and made the following suggestions and conclusions: The
involved annealing furnace lacks an effective quality assurance system, and the design, manufacturing and installation process is not standardized. It is an obvious quality defect, which constitutes or intensifies the temperature gradient of the furnace in the height and width directions, is not conducive to stress relief, and forms a causal relationship with the bursting of glass products.
