Severstal Russian Steel division’s Cherepovets Metallurgical Plant has put into commercial operation the ball rolling mill No 3, SHPS-3. The new equipment made it possible to master the production of grinding balls with a diameter of 80-100 millimeters. Grinding balls with a diameter of 80-100 millimeters are used in the mills of enterprises specializing in ore and gold mining. Within the framework of GOST, which regulates the product standard, the new balls are distinguished by an increased diameter. At the same time, hardness, chemical composition and other indicators remained unchanged. The production technology of the new product is also different. Thus, the billet is heated in a new mill using a methodical heating furnace that runs on natural gas. On ShPS No 1 & No 2 heating is carried out by the induction method. In addition, a low temperature tempering furnace was installed at SHPS 3. The products enter it after quenching. There the balls, depending on the section width, undergo heat treatment for 70 to 120 minutes.Such products are in demand among the enterprises of the mining and gold mining industry in Russia, as well as in the countries of Central Asia. Severstal has experience in supplying grinding balls not only to enterprises in the Russian market, but also to neighbouring countries. For example, by the end of 2020, the company quadrupled its sales of such products in diameters from 20 to 60 millimeters to enterprises in Kazakhstan. In 2021, for one of the gold mining enterprises in this country, Severstal carried out pilot deliveries of balls in a new range of 80 to 100 mm. Their volume amounted to more than two thousand tons. The quality of the grinding balls produced at CherMK helps to develop sales - in particular, their high resistance to the products of local manufacturers.
