In addition, the slag from the BOS plant such as converter slag and ladle slag has useful properties once weathered to allow for expansion of the lime-bearing material.
EAF slag is a strong and durable material which is highly versatile and ideally suited for use as an aggregate in many applications.
The slag derived from stainless steel production presents particular challenges, owing to the handling of fines in its cooled state. We also have solutions for complying with the most stringent environmental regulations, which require additional precautions when handling stainless slag owing to the risk of airborne dust emissions.
The steelmaker benefits from slag recycling by avoiding the cost of landfill. The community benefits, too. Slag is a man-made mineral, therefore its use as an aggregate in place of a natural aggregate product avoids the environmental footprint from quarrying.
Slag is a valuable resource for any steelmaker. Integrated steelmakers sell blast furnace slag - which is naturally cementitious in quality - into the cement industry.
Blast furnace slag is naturally cementitious and is commonly used in the cement industry to blend with other materials.
Steel slag from the converter furnace is also suited for use in cement manufacturing, after it is milled to a fine material which absorbs into the mix in the kiln. Indeed, cement made with slag aggregate may achieve permeabilities and strengths that compare favorably to concrete made with conventional aggregates.
Superfine slag cement is used as a feedstock for the cement kiln.Cement rotary kiln, which is mainly used for calcinating cement clinker, is the main equipment of the new dry type cement production line. This equipment is mainly composed of cylinder, supporting device, supporting device with catch wheel, transmission device, lubrication device, mobile kiln head and sealing device at the end of the kiln
