为了解决和探求代替成本较高的钢丝绳切块的钻粒,辽宁煤矿地质勘探局委托沈阳有色金属工业学校,研究使用钢水直接浇铸钢质钻粒的问题.双方对其技术问题,进行了系统地研究,对所铸的钢粒进行了生产实验工作.现根据该校的研究资料结果,加以综合整理,作一扼要介绍,以供参考.一、钢粒的铸造钢粒铸造的方法,基本同于生铁钻粒的制造方法.将熔好的钢水均匀地倒落作转动的浇铸辊的中间,钢液流由于受浇铸辊的旋转作用,而被粉碎,溅起室中,然后,飞落入辊周围的冷却水池中即成.
In order to solve and explore the replacement of high-cost wire rope diced diamond particles, Liaoning Coal Geological Prospecting Bureau commissioned the Shenyang Nonferrous Metal Industry School to study the use of molten steel directly cast steel drill particles.The two sides of its technical problems, systematically Research, the cast steel grain production experiment.According to the school’s research data results, to be consolidated, make a brief introduction for reference.First, the grain of steel casting method of casting, with the basic In the method for making cast iron pellets, the molten steel is poured down evenly into the middle of a rotating casting roll, the molten steel stream is pulverized and splashed in the chamber due to the rotation of the casting roll, Serve around the cooling pool in the roller.
