The invention belongs to the technical field of metallurgy machinery, and in particular relates to a linear rod cogging mill. An upper working roller and a lower working roller are driven by a main transmission device to assemble and rotate, and roller seams are adjusted up and down by driving the upper working roller to assemble through a dynamoelectric press down device. Large continuous casting square blanks are rolled into needed small square blanks through two rollers of reversible rolling mills. The cogging mill can roll the large continuous casting square blanks into the needed small square blanks, improve the product quality, promote product grades, optimize and widen product structures, and improve the continuous casting output and the product yield of the whole factory, is not limited by the specifications of upstream continuous casting blanks, and improves the forging ratio. The cogging mill can be arranged in all newly built high-speed wire machine sets or wire reformationmachine sets and in particular partial prior linear rod machine sets which can be reformed by utilizing the prior rolling mill transmission devices so as to save partial investment.
Description
technical field [0001] The invention belongs to the technical field of metallurgical machinery, and in particular relates to a blanking machine for rough rolling of wire and bar. technical background [0002] Wire rod is one of the important products of the iron and steel industry, which is widely used in various infrastructure construction, construction engineering construction and metal products industry. my country began to produce high-speed wire rods in 1987. At present, my country has become the country with the most high-speed wire rod production lines and the largest output in the world. [0003] Before the advent of continuous casting machines, wire rod production was based on casting steel ingots and heating the steel ingots to obtain qualified square billets before producing wire rods. Due to the high labor intensity, high environmental pollution, and high energy consumption in the processes of die casting and billet opening, after the successful use of continuou...
