石墨化钢是初轧开坯机轧辊远景材料之一,它可以代替目前所用的一系列过共析钢。石墨化钢组织中的游离石墨,将会提高热轧辊的抗热裂能力,改善与轧材的咬合条件。铸件中石墨化钢的组织通常是在热处理过程中形成的,可是由于热处理的结果,在获得球状石墨的同时,制品的成本也提高了。因此,现在迫切的任务是使石墨化钢在铸态下获得球状石墨。乌克兰冶金科学研究所为了将铸态(不经热处理)石墨化钢轧辊用于型材轧机,在
Graphitized steel is one of the long-rolled materials for the bloom-rolling machine, which can replace the currently used series of hypereutectoid steel. Graphitized steel in the organization of free graphite, will improve the thermal roller hot cracking resistance, improve the condition with the rolling bite. The structure of graphitized steel in castings is usually formed during heat treatment, but as a result of the heat treatment, the cost of the product is increased while obtaining spherical graphite. Therefore, an urgent task now is to obtain graphitized graphite in the as-cast graphite state. Ukrainian Institute of Metallurgical Science In order to use as-cast (non-heat-treated) graphitized steel rolls for profile mills,
