The basis of such minerals is calcium carbonate contained in chalk, calcareous tuffs, etc., the development of deposits of which is most often carried out in an open way, including the use of blasting. The rock coming from the quarry is crushed, and then the material is scattered on screens to ensure the consistency of the fractional composition. Flux limestone is used as a flux at Russian metallurgical plants, as well as at enterprises for the production of lime. They are divided into those that are designed for use as additives in blast furnace charge, in the composition of pellets and sinter, as well as those that are used in ferroalloy and steel production, in lump form in the charge of open-hearth furnaces. The specified standard normalizes the content of calcium oxide in the feedstock, which for classes 2 and 3 should be at least 52 and 40 percent, respectively, as well as substances insoluble in hydrochloric acid, moisture and mass fraction of the sum of pieces with a particle size less and more than the allowable limit. There are other varieties of flux limestone , for example, in the form of powders intended for the production of non-fired periclase products and masses used for lining oxygen converters. Raw materials do not have an expiration date, and standard railway wagons are used for its transportation, into which it is loaded in bulk. ← to the section "Products" 2010 © JSC "Studenovskaya Joint-Stock Mining Company" All rights to the materials on the site are protected in accordance with the legislation of the Russian Federation. website development
