铸钢件渣气改善方法探究

Exploration of improving method of gas slag porosity in steel casting

渣眼、气孔、砂眼是铸钢件的常见铸造缺陷,不仅影响铸件的美观,也会影响其使用性能,甚至使铸件报废。本文通过探讨销孔座铸钢件产生渣气孔的各种原因和影响因素,通过多次改善试验,结合使用超级过滤技术,在诸多因素中抓住主要影响铸造渣孔的原因,从而解决了销孔座铸件渣气孔的缺陷问题。

Slag eye,gas porosity and sand hole are the common defects in steel casting.These defects will not only affect the surface quality of steel casting,but also affect the performance of the part,even make the part scrapped.The various causes and impact factors of gas slag porosity in pin socket steel casting have been discussed in the text.Through lots of improving tests,in combination of super filter technique,the main impact factor has been found.Thus in this way,the defects of the gas slag porosity for pin socket steel casting have been solved.
