Magnesia-carbon wet-process spray coating and application method thereof
The invention belongs to the field of refractory materials, and particularly relates to a magnesia-carbon wet-process spray coating and an application method thereof, and the magnesia-carbon wet-process spray coating is prepared by treating graphite and magnesia and matching the treated graphite and magnesia with a high-efficiency water reducing agent. The magnesium-carbon refractory material is sprayed by using a wet process to perform hot-state repair and lining making on a steel ladle, so the defects of high dust content, high rebound rate, low material bonding strength and the like of semi-dry-process spraying are overcome, the whole lining can be maintained, the service life of the steel ladle is prolonged, the consumption of the refractory material is reduced, steelmaking productionefficiency is improved, and labor consumption is reduced.
本发明专利属于耐火材料领域，尤其涉及一种镁碳质湿法喷涂料及施用方法，本发明通过对石墨和镁砂料进行处理，并配合高效减水剂制备镁碳质湿法喷涂料。采用湿法喷涂镁碳质耐火材料对钢包进行热态修补、造衬，克服了半干法喷涂的粉尘大，回弹率高，材料结合强度低等缺点，同时能对整个内衬进行维修，提高钢包使用寿命，降低耐火材料消耗，提高炼钢生产效率，降低人工消耗。
