The raw material characteristics of high-sulfur iron and zinc slag and the problems in the production process were analyze,such as insufficient combustion of elemental sulfur,serious slag bonding,slag viscosity and slag release difficulties.The effects of nozzle type,temperature,time and slag type on smelting and blowing are studied.The semi-suspended smelting and weak reduction temperature control blowing technology is proposed,which makes full use of the sulfur combustion calorific value and can obtain the waste slag with higher environmental protection requirements.
