Description

Technical Field

[0002] In the process of using a twenty-high mill to produce high-silicon electrical steel, there are frequent accidents of brittle strip fractures during the start-up and tail-swinging stages. The strip was coiled twice using the mandrel and belt coiler that come with the mill, but it failed to coil successfully after multiple attempts. The strip frequently broke at the jaws or at the belt coiler's head wrapping position, causing the mill to shut down for a long time, seriously affecting production efficiency. In fact, the strip could not be coiled successfully to complete the sheeting, and the steel coil could not be rolled in subsequent passes, which eventually forced the entire roll of electrical steel to be taken offline and scrapped, causing a sharp increase in production costs. At the same time, in the process of handling strip fragments, operators were exposed to dangerous environments for a long time, which greatly reduced the safety factor of the operation and made it impossible for the operator's safety to be guaranteed.
