Development of a method for effective strengthening rolled rebar with diameter of 8 mm of ordinary quality steel in terms of mill 320 SPC-1 at OJSC «BSW – Management Company of the Holding «BMC»

Abstract

The global competition, unstable situation in the world market of rolled metal products, as well as increasing with each day the requirements of consumers of products pose complex tasks for the manufacturer, which must be solved in the shortest possible time. One of these tasks is to expand the range of rebar rolled products in the conditions of the variety rolling shop no. 1 on the continuous small-grade rolling mill 320. Until recently, rolling of reinforcing profiles with a diameter from 10 mm to 40 mm was carried out at the 320 rolling mill. In order to expand the range of rebar products, work was carried out to develop a production technology for profile no. 8 rod fittings with thermal hardening in the mill line for class 500.
