Abstract : this paper describs the smelting technology of high toughness nodular cast iron qt400 - 18 in cupola . the choice of raw material , chemical composition and the process of nodularization and inoculation is analyzed also . as a result , the reasonable semlting technology is determined to provide reliable gurantee for producing qualified casting
文摘:本文阐述了在冲天炉熔炼条件下铸态高韧性球墨铸铁qt400 - 18生产技术工艺，并对原材料选用、化学成份选择、球化处理工艺、孕育处理工艺进行了分析研究，确定了合理的熔炼工艺，为生产合格材质铸件提供可靠的保证。
It ' s pointed out that , under the condition of vim refining , the amount of oxide inclusions residue in molten steel increases with the increased loss of deoxidizing elements , and the key of melting extra - low oxygen steel is to avoid the thermal decomposition of lining material ; the size of deoxidizing products increases with the increased degree of supersaturation of deoxidizing elements ; larger inclusions granules found in extra - low oxygen steel come mainly from lining material
结果表明，在真空感应熔炼条件下，残留在钢中的氧化物夹杂数量随脱氧元素铝烧损量增加而增加，熔炼超低氧钢的关键是避免炉衬热分解；脱氧产物尺寸随脱氧元素过饱和度增加而增加；超低氧钢的大颗粒夹杂主要来自炉衬材料。
