Steel ladle lining wet-process spray coating and use method thereof
The invention discloses a steel ladle lining wet spray coating and a use method thereof. The spray coating comprises the following components: 12-14 wt% of alumina particles, 50-52 wt% of tabular corundum particles, 19-23 wt% of white corundum fine powder, 4-6 wt% of fused magnesite fine powder, 4-6 wt% of alumina micro powder, 2-6 wt% of a binding agent, 1-3 wt% of a sintering accelerator, 0.1-0.3 wt% of an anti-explosion agent, 0.8-1 wt% of a coagulant and 2-4 wt% of a hardening accelerator. The preparation method comprises the following steps: weighing the raw materials except the hardening accelerator according to the formula, and uniformly mixing to prepare a spraying main material; the preparation method comprises the following steps: mixing the prepared spraying main material with water to form a castable, spraying the steel ladle lining by using a spraying machine, and blowing the spraying main material and a hardening accelerator to a nozzle by high-pressure air in the spraying process, so that the spraying main material sprayed on the steel ladle lining loses fluidity and is attached to the lining. The spray coating provided by the invention can enable a steel ladle to run for more than 40 times.
本发明公开一种钢包内衬湿法喷涂料及其使用方法，喷涂料的组成成分包括：12‑14wt%矾土颗粒，50‑52wt%板状刚玉颗粒，19‑23wt%白刚玉细粉，4‑6wt%电熔镁砂细粉，4‑6wt%氧化铝微粉，2‑6wt%结合剂，1‑3wt%促烧结剂，同时外加0.1‑0.3wt%防爆剂，0.8‑1wt%促凝结剂和2‑4wt%促硬剂；按照配方称取促硬剂以外的各原料，将其混合均匀，制成喷涂主料；将制成的喷涂主料加水混合成浇注料形式，然后使用喷涂机对钢包内衬进行喷涂，喷涂过程中高压风同时将喷涂主料，促硬剂吹送到喷嘴，使喷涂在钢包内衬的喷涂主料失去流动性，附着在内衬。本发明提供喷涂料可使钢包运行40次以上。
