Abstract

The workers of the Azovsta’ integrated iron-and-steel works have determined the causes of early wear of main roofs of open-hearth furnaces. They have resorted to lining the main roofs by periclase-chromite refractories of grade LIIIV produced in Slovakia. The use of refractories of grade LIIIV has increased the endurance of the main roofs of open-hearth furnaces by 100 heats. A petrographic study has shown that the high operating properties of articles made of LIIIV are due to their composition and structure, obtained as a result of the use of high-quality initial materials (chromite ore and magnesite powder) and a modern manufacturing process. Introduction of the developed manufacturing process has increased substantially the endurance of the linings and reduced the number of cold repairs of the open-hearth furnaces and the consumption of refractories.
