Abstract

Reflective types furnace: Martin furnace; Siemens–Martin furnace (double-bath unit for steel making), still have taking an important place among the total quantity of all industrial steel-smelting units in Ukraine. Due to the fact that they are cane to correctly work in the raw material base that is currently available for domestic metallurgical enterprises. The рrocessing done of information, data and literature made it possible to confirm that in the production of steel, the generic term of one company for the operation on the reflective furnaces, under other normal conditions, is determined by the using term of the refractory lining. Due to the fact that, it is very difficult to carry out hot repair work at the during the operation of the furnaces and capital works are almost impossible. According to the evidence of a number of scientific works and industrial experience of recent years, of all the main structural elements of the furnace protected by refractory lining materials, most often, the vault itself limits the overall operational resource of one use refractory lining cicle. At the work achieved the purposed and formed a general concept of typification the structure and structural features of the vaults on the reflective types furnaces, which were used in recent years in the working conditions of Ukrainian metallurgical enterprises, and to characterizeted of the main types materials, for their refractory lining. Defined the factors that significantly affect the stability of the vault of reflective types furnaces and limit the operational resource of their lining. It was established that due to a series of imperfections, it is advisable to: creation and use of more advanced modern refractory lining materials for vaults; the development of new structures or the modernization of the existing vaults for furnaces the reflective type, which will contribute to the improvement of their explantation conditions, increase the resource of refractory lining use, and improve the environmental indicators of the process.
