Abstract
Description
Technical Field
[0001] The utility model relates to the field of steel strip processing, in particular to isothermal quenching equipment for steel strip processing. Background Art
[0002] Steel belt refers to a conveyor belt made of carbon steel that is used as the traction and carrying component of the belt conveyor. It can also be used to bundle goods. It is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. When processing, the steel belt needs to be quenched. Quenching is a heat treatment process method that heats the steel to above the critical temperature, keeps it warm for a certain period of time, and then cools it at a cooling rate greater than the critical cooling rate to obtain an unbalanced structure dominated by martensite. Quenching is the most widely used process method in steel heat treatment technology.
[0003] However, traditional quenching equipment cannot effectively insulate itself during use, which may easily affect the surrounding environment. In addition, general quenching equipment does not have a steel belt positioning device, which makes it easy for the steel belt to deviate when entering the quenching equipment and hit the internal components of the quenching equipment, which may easily cause damage to the internal components of the equipment and affect the quenching efficiency. For this reason, we have proposed an isothermal quenching equipment for steel belt processing. Utility Model Content
