High-strength carbon-free steel ladle wall corundum brick and application thereof to steel ladle
The invention relates to the technical field of refractory materials, and provides a high-strength carbon-free steel ladle wall corundum brick which comprises the following raw materials in parts by weight: 60-70 parts of magnesia, 10-18 parts of corundum, 10-15 parts of magnesium aluminate spinel and 8-10 parts of a composite binder. The composite binding agent is composed of a liquid phase and a solid phase. The liquid phase is an AlCl3 solution; and the solid phase is composed of alpha-Al2O3 micro powder and gamma-Al2O3 micro powder. By means of the technical scheme, the problems that in the prior art, a steel ladle wall brick is low in thermal shock resistance, and adverse effects are generated on molten steel recarburization in the steel grade smelting process are solved.
本发明涉及耐火材料技术领域，提出了一种高强度的无碳钢包包壁刚玉砖，包括以下重量份组分的原料：60~70份镁砂、10~18份刚玉、10~15份镁铝尖晶石、8~10份复合结合剂；所述复合结合剂由液相和固相组成；所述液相为AlCl3溶液；所述固相由α‑Al2O3微粉和γ‑Al2O3微粉组成。通过上述技术方案，解决了现有技术中钢包包壁砖低热震稳定性和在冶炼钢种过程中对钢水增碳产生不良影响的问题。
