JT1250SA steel belt
Special steel belt technical requirements
Special steel strip is made by multiple deep processing on the basis of strip steel, and the production of strip steel is simply through smelting, continuous casting and hot rolling → cold rolling → trimming into strip steel coils, and its various mechanical properties None of them meet the requirements of special steel belts, and are usually used for decoration or made into workpieces for static use.
To process strip steel into steel strip, first the strip needs to undergo aging treatment, which is the most critical process in the process of strip steel production and processing. Since the strip steel will have plate-shaped waves and warping after cold rolling, and the residual stress distribution will be uneven, it needs to be stretched and straightened to relieve the stress and increase the hardness of the base metal to meet the performance requirements of the special steel strip.

● The size of the steel belt is selected correctly, and it is determined according to the diameter of the drum, the production speed, and the use environment.
● The steel belt can be supplied with open ends and on-site welding; it can also be pre-welded into a ring field kit.
● The steel has different quality and processing precisions, which can be applied to different fields to achieve the best economic benefits.
Steel belt guide rubber strip
In the production operation of the steel belt, affected by external factors, the running track will shift left and right. The rubber guide strips on both sides of the back of the steel belt have very good peel strength, which effectively prevents the steel belt from shifting too much.
