Description

Technical Field

[0001] This utility model relates to the field of steel rolling guide technology, specifically a slitting guide structure to prevent slag adhesion. Background Technology

[0002] Steel rolling is a pressure processing process that changes the shape of steel ingots and billets between rotating rolls to obtain the desired shape or improve the internal quality of steel. With the development of steel rolling technology, the technology and process are now becoming more mature and stable. It is essential to innovate on the basis of the original structure and process and improve the cost and technology.

[0003] In existing technology, how can we ensure that the red billet enters the rolling mill smoothly in the rolling guide? However, most imported guides in finishing mill have the following characteristics when assisting the red billet to enter the rolling mill: high speed and large impact force. Therefore, the requirements for the key stress-bearing parts of the imported guide are very high, which leads to the guide groove being easily worn and sticking with iron oxide when entering the rolling mill.
