SLAG COATING MATERIAL FOR CONVERTER

摘要

PURPOSE: A slag coating material for a converter is provided, which recycles waste refractory material and is improved in tolerance. CONSTITUTION: A slag coating material comprises 1-2 parts by weight of waste magnesia-carbon refractory brick crushed one; and 15-75 wt% of converter slag. Preferably the particle size of the waste magnesia-carbon refractory brick crushed one is 1-100 mm. The basicity ratio (CaO/SiO2) of the converter slag is 2-5, and its iron content is about 20 wt%.
