Steel slag

Steel slag Product introduction

Steel slag


Steel slag is the slag discharged in the process of steel making, which can be divided into converter slag, flat slag and electric furnace slag based on the furnace type, and is mainly composed of calcium, iron, silicon, magnesium and a small amount of aluminum, manganese and phosphorus and other oxides. It is a large industrial solid waste with a discharge of about 15% to 20% of crude steel output. At present, the annual emissions of steel slag in China are as high as 80 million tons, and the accumulative pile is about 1 billion tons. Steel slag is widely used in the production of steel slag cement, slag powder, slag brick and building block, environmental repair materials and other industries.




Steel slag

Steel slag Technical process   


The steel slag processing is divided into preprocessing stage, screening stage, iron removing and screening and grinding stage. In steel slag produced by steel plant, some of the slag particle size exceed the biggest feeding size of first crushing. You need to use breaking hammer to preprocess. The steel slag satisfies the feeding requirement of the equipment after pretreatment. The pretreated steel slag is further crushed and screened. The raw material is crushed and separated by jaw crusher, cone crusher, vertical shaft impact crusher and screening equipment to a certain size eventually, which is used for building materials or further processing. In the process of iron removing, the cone crusher and vertical shaft impact crusher are prohibited from iron in the crushing and screening process. Moreover, Iron is a valuable component of steel slag. The iron removal equipment in the production line will not only ensure the normal operation of the equipment, but also bring huge economic benefits. In the grinding stage, after the crushed and magnetic separation materials are further ground by the ball mill, we can obtain different fineness of materials, which can be used as brick, cement and concrete.
