Plastic refractory for repairing furnace lining of medium-frequency induction furnace and preparation method of plastic refractory
The invention relates to a plastic refractory for repairing a furnace lining of a medium-frequency induction furnace and a preparation method of the plastic refractory. According to the technical scheme, 63.0 wt%-78.0 wt% of vanadium iron slag, 12.0 wt%-17.0 wt% of basalt, 8.0 wt%-13.0 wt% of bauxite and 2.0 wt%-7.0 wt% of bentonite serve as raw materials, a binding agent accounting for 4.0 wt%-5.5 wt% of the raw materials is added, the raw materials are mixed to be uniform, and the plastic refractory for repairing the furnace lining of the medium-frequency induction furnace is obtained. The vanadium iron slag comprises the following main chemical components: more than or equal to 83.5 wt% of Al2O3, more than or equal to 9.0 wt% of MgO, less than or equal to 5.0 wt% of CaO, less than or equal to 0.3 wt% of SiO2, less than or equal to 0.2 wt% of Fe2O3 and less than or equal to 0.2 wt% of IL. Therefore, the method has the characteristics of environmental friendliness, simple process and low production cost; and the prepared plastic refractory for repairing the furnace lining of the medium-frequency induction furnace is convenient in construction mode, high in bonding strength, excellent in slag resistance and long in service life.
本发明涉及一种中频感应炉炉衬修补用可塑料及其制备方法。其技术方案是：先以63.0～78.0wt％的钒铁渣、12.0～17.0wt％的玄武岩、8.0～13.0wt％的铝矾土和2.0～7.0wt％膨润土为原料，再外加所述原料4.0～5.5wt％的结合剂，混合均匀，即得中频感应炉炉衬修补用可塑料。所述钒铁渣的主要化学成分是：Al2O3含量≥83.5wt％，MgO含量≥9.0wt％，CaO含量≤5.0wt％，SiO2含量≤0.3wt％，Fe2O3含量≤0.2wt％，IL≤0.2wt％。因此，本发明具有环境友好、工艺简单和生产成本低的特点；所制备的中频感应炉炉衬修补用可塑料施工方式便捷、结合强度高、抗渣性能优良和使用寿命长。
