The wear mechanism of a quartzite lining of induction crucible furnaces during iron and steel smelting is presented. It is established that the main cause of lining wear is a decrease in its strength due to transition of the tridymite joints into cristobalite, which is more readily washed off crucible walls by moving metal and slag. The second important factor of wear is the choice of quartzite raw material, its substance and grain size compositions, firing regime, and melting technology during furnace operation. Silicon reduction from silica of the carburizer lining and within the cast iron composition is a subsidiary factor of crucible lining wear.
