Preparation method of nodular cast iron for axle housing casting
PendingCN119663098Areduce waiting timeadequate responseProcess efficiency improvementYarnCarbide silicon
The invention discloses a preparation method of nodular cast iron for axle housing castings. The nodular cast iron comprises the following raw materials: 10-30% of pig iron, 30-60% of scrap steel and 15-40% of foundry returns. 1.5%-2.5% of a carburant and 1.5%-2.0% of 75 ferrosilicon; the preparation method comprises the following steps: preparing the following components in percentage by weight: 0.4%-0.8% of electrolytic copper, 0.1%-0.4% of a silicon carbide pretreating agent, 0.8%-0.95% of an Mg30-containing spheroidized core-spun yarn and 0.2%-0.6% of 0.05% to 0.15% of an Ikine 958 stream inoculant; and through the arrangement of the pretreatment step, the metallurgical reaction is more sufficient, the molten iron is pretreated, and preparation can be better made for subsequent spheroidizing treatment. According to the single-wire feeding spheroidizing method, the spheroidizing process and the inoculation process are separated, the waiting time between spheroidizing cored wire feeding and inoculation treatment is saved, the wire feeding time is shortened, and the production cost is reduced. And the spheroidizing ladle is additionally arranged between the smelting furnace and the pouring ladle, so that the reaction is more sufficient, and the production efficiency is improved. The nodular cast iron prepared by the method is good in comprehensive performance, the preparation cost is reduced, and an axle housing cast by the nodular cast iron is good in mechanical performance and long in service life.
