粒化铸铁渣是生产粘土砖的高效掺合料。科捷利斯克砖厂利用N·A利哈切夫汽车厂的粒化铸铁渣作瘠化掺料代替部分锯末,使粘土砖的极限抗压强度提高15％,极限抗折强度提高30％。工业生产采用下列配比最为有利:亚粘土70％,锯末20％,铸铁渣10％。工厂中采用箱式给料器对粒化渣进行配料,采用2对辗压辊对物料进行处理,即进行粗磨和细磨。
Granulated cast iron slag is an efficient admixture for the production of clay bricks. Kocelisk Brick uses the granulated cast iron slag from N.A. Likhachev Automobile Factory as a deuteration compound instead of a portion of sawdust to increase the ultimate compressive strength of the clay brick by 15% and the ultimate bending strength by 30%. The following ratios are most favorable for industrial production: 70% for sub-clay, 20% for sawdust, and 10% for cast iron slag. In the factory, a box feeder is used to batch the granulated slag, and the material is treated with two pairs of press rolls, ie rough grinding and fine grinding.
