[0002] The production methods of the chain plates on the chains covered by the current national standards and industry standards are the same: the basic process is to punch the chain plates with steel plates, flat steel, and strip steel, and then punch the chain plate holes. The process has the following three shortcomings: first, the punching of the chain plate requires a large-tonnage punching machine and a mold, so the power consumption is large; If it is too large, the chain plate will be deformed and uneven, and the edge of the punched chain plate has a slope, which will easily affect the product quality

The invention relates to a production method of chain plate-type web, which pertains to productive sphere of steel products. The invention mainly starts with raw materials of chain web, changes traditional manufacturing technique and adopts drawing method. The invention is characterized in the following steps: transferring band steel (1) rolled down by normal craft to cogging mill (2) to produce crude product (3); transferring the crude product to finishing mill to get end product (5). The invention has the advantages of saving energy, high production efficiency and high quality.
Description
technical field [0001] The invention belongs to the field of steel production, and relates to a method and a device for producing chain plate strips. Background technique [0002] The production methods of the chain plates on the chains covered by the current national standards and industry standards are the same: the basic process is to punch the chain plates with steel plates, flat steel, and strip steel, and then punch the chain plate holes. The process has the following three shortcomings: first, the punching of the chain plate requires a large-tonnage punching machine and a mold, so the power consumption is large; If it is too large, the chain plate will be deformed and uneven, and the edge of the punched chain plate has a slope, which will easily affect the product quality. Contents of the invention [0003] Technical issues solved: [0004] Changing the production process of the chain plate on the existing chain (hereinafter referred to as the chain plate) can ove...
