NEW CARBON-CONTAINING REFRACTORIES FOR THE LINING OF STEEL-TEEMING LADLES FROM THE KOMBINAT MAGNEZIT JOINT-STOCK CO.

摘要

Test results for new carbon-containing refractories for the lining of steel-teeming ladles - PUSK, PShUK, PShUP, PUPK, and ShPUP-grade, available from the Kombinat Magnezit JSC, are presented. The properties of refractory components (including heat resistance) in the "as-received" and "subjected to coking" condition are reported. The enhanced resistance of the new materials to thermal spalling under varying temperature conditions is noted. Results of the tests (carried out at the Magnitigorsk Iron-and-Steel Works and Oskol'skii Electrical ISW) provide the basis for an analysis of the economic feasibility of large-scale production of these materials.
