铁碳硅合金熔体中的氧化反应及其中的“坩埚反应”,是液态铸铁和液态可锻铸铁中最重要的冶金过程。此反应将决定下列状况: 1)坩埚侵蚀与否以及侵蚀程度; 2)铁水是否被渣复盖或裸露于大气中; 3)是否生成一氧化碳,即发生碳沸腾; The oxidation reaction in the iron carbon-silicon alloy melt and the “crucible reaction” therein are the most important metallurgical processes in liquid iron and liquid malleable iron. This reaction will determine the following conditions: 1) whether the crucible is eroded or not, and 2) if the molten iron is covered by slag or exposed to the atmosphere; 3) if carbon monoxide is generated,
