为了改善钢锭表面质量和降低金属切头损失,在乌克兰科学院铸造研究所的协作下,切列波维茨克冶金工厂进行了用上小下大钢锭模用发热板加热上部浇注镇静钢的试验,从而避免了用保温帽和大头模子浇注镇静钢,而且可降低金属的切头消耗。在研究过程中试验了含17种成分的混和料,包括作为燃烧剂的铝粉和磨碎的75％的矽铁以及作为氧化剂的铁皮、铁矿石和锰矿。得出最佳的发热混和料成份如下:15—25％铝粉,
In order to improve the ingot surface quality and reduce the metal cut head loss, in collaboration with the Foundry Institute of Ukraine Academy of Sciences, Cherepovets metallurgical plant was carried out with the upper and lower ingot mold with heating plate heating the upper part of the cast steel test, Thus avoiding the use of insulation caps and bulk mold casting dead steel, but also reduce the metal cutting head consumption. A mixture of 17 ingredients was tested during the study, including aluminum powder as a combustion agent and ground 75% ferrosilicon, as well as iron skins, iron ore and manganese ore as oxidizers. Come to the best fever mixture ingredients are as follows: 15-25% aluminum powder,
