Coating for runner brick, preparation method and use method of coating, coating and runner brick
The invention provides a coating for a runner brick, a preparation method and a use method of the coating, a coating and the runner brick, and belongs to the technical field of runner bricks for steel-making die casting pouring, the coating for the runner brick comprises a first component and a second component; the first component is prepared from the following components in parts by mass: 30 to 50 parts of aluminum-rich spinel; 25 to 40 parts of brown aluminum oxide; 6-15 parts of activated aluminum oxide; 3 to 15 parts of magnesia; 4 to 10 parts of kyanite; the second component comprises the following components in parts by mass: 4-9 parts of a binding agent; 45 to 80 parts of water; and an auxiliary agent. The coating for the runner brick can improve the thermal shock resistance and slag corrosion resistance of the runner brick, can reduce cracking and stripping of the brick in the using process, and effectively solves the technical problem that a surface coating is easy to fall off in the cold and hot alternating process in the existing runner brick, so that the inclusions in axle steel are reduced.
本发明提供了一种流钢砖用涂料及其制备方法和使用方法、涂层、流钢砖，属于炼钢模铸浇注用流钢砖技术领域，所述流钢砖用涂料包括第一组分和第二组分；以质量份数计，所述第一组分包括以下组分：富铝尖晶石30～50份；棕刚玉25～40份；活性氧化铝6～15份；镁砂3～15份；蓝晶石4～10份；以质量份数计，所述第二组分包括以下组分：结合剂4～9份；水45～80份；助剂。该流钢砖用涂料能够提高流钢砖的抗热震稳定性和抗渣侵蚀性能，能够减少砖使用过程中的开裂和剥落，有效解决了现有流钢砖中存在的在冷热交变过程中表面涂层易脱落的技术问题，从而降低了车轴钢中夹杂物。
