Description

technical field [0001] The invention relates to the technical field of die steel heat treatment, and more specifically relates to a die steel heat treatment system and process for improving corrosion resistance, toughness and polishability. Background technique [0002] Die steel is a type of steel used to make molds such as cold stamping dies, hot forging dies, and die-casting dies. Mold is the main processing tool for manufacturing parts in industrial sectors such as machinery manufacturing, radio instruments, motors, and electrical appliances. The quality of the mold directly affects the quality of the pressure processing process, the precision output of the product and the production cost, while the quality and service life of the mold are mainly affected by the mold material and heat treatment in addition to the reasonable structural design and processing accuracy. [0003] The heat treatment of mold steel is usually carried out in a heat treatment furnace (ie, heating...

AI Technical Summary

Problems solved by technology

[0003] The heat treatment of mold steel is usually carried out in a heat treatment furnace (ie, heating furnace). There is a common disadvantage in existing heating furnaces: the temperature at the periphery of the furnace body is higher than the temperature at the center. When performing heat treatment of mold steel, it must be ensured The overall heating temperature of the mold steel is uniform, but due to the structural limitation of the existing heating furnace, the temperature inside the furnace body needs to be heated for a long time to reach a balanced state, and because the temperature at the center is always low, it is difficult to ensure uniform heating of the mold steel. As a result, the heat treatment effect of the die steel is affected, and the corrosion resistance and toughness of the die steel after heat treatment are greatly affected.
