Magnesia-carbon modifier prepared from tundish residual linings
The invention provides a magnesia-carbon modifier prepared from tundish residual linings. The modifier is prepared by taking tundish residual linings, coke breeze, flaky graphite and magnesite clinker as main raw materials, adding a binding agent and carrying out the processes of mixing, ball pressing, natural drying and the like. The magnesia-carbon modifier has the characteristics of high magnesia content, high carbon content and good slag adjusting effect, and can effectively adjust the final slag components of a converter, improve the MgO content in the slag, reduce the FeO content in the slag, and improve the melting point and viscosity of the slag by applying the magnesia-carbon modifier to the converter and combining the dissolution of magnesia and the reaction between carbon and ferrous oxide. The combination state of a slag bonding layer and a furnace lining is effectively improved, and the slag splashing furnace protection effect is optimized. The magnesia-carbon modifier can effectively prolong the service life of a converter, and has important significance for saving energy, reducing consumption, protecting the environment and increasing economic benefits.
本发明提供了一种用中包残衬制备的镁碳改质剂,该镁碳改质剂以中包残衬、焦末、鳞片状石墨、烧结镁砂为主要原料,添加结合剂,经过混练,压球,自然干燥等工序进行制备。本发明的镁碳改质剂具有氧化镁含量高、碳含量高、调渣效果高的特点,将其用于转炉上并结合氧化镁的溶解及碳与氧化亚铁的反应,可有效对转炉终渣成分进行调整,提高渣中的MgO含量,降低渣中的FeO含量,提高炉渣熔点及黏度,有效改善粘渣层与炉衬的结合状态,优化溅渣护炉效果。本发明的镁碳改质剂可有效提高转炉炉龄,对于节能降耗、环境保护、增加经济效益具有重要的意义。
