苏联乌拉与马西伯利亚的一些选矿厂、烧结厂、焦化厂,使用带有铸渣层的复合钢管、弯管、板块等,输送碎焦、精矿粉、炉渣灰等一类磨蚀性强的材料,取得良好效果。输送方式既有自流,又有水力或气动输送。这种铸渣件特别耐磨蚀,渣层复合钢管的使用寿命是普通钢管的4～10倍,弯管则更长,可达5～22倍。铸渣板块用于散料的流槽、受料斗的衬板,寿命也要比锰钢衬板长4倍左右。实践表明,铸渣制品既可做内衬材料,以保护金属件不被磨耗,又可做金属部件的代用品。使用情况见附表。附有渣层的复合钢管,采用离心法铸制。靠金属与渣固化时收缩率不同所产生
A number of mineral processing plants, sintering plants, coking plants in the Soviet Union Urals and Masovian, the use of composite steel pipe with cast-in-slag layer, elbows, plates and the like, transport crushing coarsening, concentrate powder, slag ash and other abrasive materials , Achieved good results. Conveying methods both gravity, as well as hydraulic or pneumatic transport. This slag casting parts are particularly resistant to abrasion. The service life of slag-clad steel pipe is 4 to 10 times that of ordinary steel pipe while the length of pipe is 5 to 22 times longer. Casting slab for bulk flow slot, by the hopper liner, life expectancy than the manganese steel liner about 4 times longer. Practice shows that the casting slag products can be made of lining materials to protect the metal parts from being worn, but also can do the replacement of metal parts. See the schedule of use. Slag layer with composite steel pipe, using centrifugal casting. By metal and slag curing shrinkage generated by different
