内容简介

Tap-hole clay is required to perform various functions. In particular, drilled-ability, that is the property to be smoothly drilled, is the most essential property to maintain stable blast furnace operation In spite of such importance, a test method to directly evaluate the drilled- ability of tap-hole clay has not been established at the present time~(2)). For the purpose of quantitatively evaluating the drilled- ability, a study was carried out on the evaluation methods in close connection with actual blast furnace operation.
