What is the endless rolling of packaged steel strip, and what are its characteristics?
Answer: Endless rolling refers to the continuous rolling of the slab through the end-to-end butt welding of the hot-rolled strip during the rolling process, or refers to the continuous casting billet with a dynamic soft reduction system The thin slab is produced and then subjected to the production process of full continuous uninterrupted rolling.
The endless rolling process overcomes the common problems of batch rolling or single coil rolling, especially when rolling ultra-thin strips. This process not only improves the yield, but also improves the quality of the strip and the stability of the threading.
The main point of the traditional batch rolling process or single-coil rolling process is to roll one intermediate billet at a time, and the strip steel exits the finishing rolling mill and enters the coiler through the output roller table and cooling device. As the thickness of the strip becomes thinner, it is important to ensure that the strip head moves smoothly on the output roller table and feeds into the coiler smoothly. Therefore, in order to roll a strip with a thickness of 1.0mm or less, it is necessary to increase the strip thickness or reduce the strip speed at the beginning of rolling until the coiling tension is established. In the first case, the thickness of the head part of the steel coil is out of tolerance; in the second case, the finishing temperature is unsatisfactory. Both of these conditions will affect the strip quality and yield. Since the folding defects of the strip steel will damage the work roll, the tail flick of the strip steel is also very important for the production of ultra-thin strip steel.
Endless rolling overcomes the above shortcomings and can achieve the following effects:
(1) Produce ultra-thin steel strip and wide and thin steel strip, broaden the product outline without reducing the yield;
(2) Stable rolling conditions to help improve product quality and yield;
(3) eliminates the troubles related to threading and tail flicking, greatly reduces the scrap rate of the rolling mill, that is, improves the yield and productivity.
Our company produces and sells packaging steel belts and packaging steel belts all year round. Customers are welcome to call for business negotiations.
