Air brick for ferrosilicon ladle and preparation method of air brick
The invention belongs to the technical field of refractory materials, and particularly relates to an air brick for a ferrosilicon ladle, which comprises a core brick with an air supply channel, the side surface of the core brick is coated with a stainless steel shell, one end of the stainless steel shell is connected with a sealing steel plate, and a through hole is formed in the center of the sealing steel plate. And a gas supply steel pipe for conveying gas to the gas supply channel is arranged at the through hole. The air brick prepared from a high-quality refractory material is used as an air supply carrier, the melting point of the refractory material is higher than the ferrosilicon smelting temperature, the refractory material does not react with ferrosilicon melt and smelting slag, and on the premise of ensuring sufficient air permeability, the air brick has the advantages of high strength, scouring resistance, slag corrosion resistance, long service life and no need of repairing in the use process, so that the labor intensity of workers is greatly reduced, and the production cost is reduced. And the problem that molten iron is easy to leak from the original air supply carrier made of a copper pipe material is also solved. Through tests, one air brick can be continuously used for 120-180 times, the service life of the air brick is far longer than that of a copper pipe for 30-50 times, and the cost performance of the air brick is far higher than that of an air supply carrier made of a copper pipe material.
本发明属于耐火材料技术领域，具体涉及一种硅铁包用透气砖，硅铁包用透气砖包括带有供气通道的芯砖，芯砖的侧面包覆有不锈钢壳体，不锈钢壳体的一端连接有密封钢板，密封钢板中心处开设有通孔，通孔处设有用于将气体传送至供气通道的供气钢管。本发明采用优质耐火材料制备的透气砖作为供气载体，该耐火材料熔点高于冶炼硅铁温度、且不与硅铁熔体及冶炼渣反应，在保证透气性足够的前提下，具有强度高，耐冲刷，耐渣侵蚀，寿命长，且使用过程中无需修补，极大的降低工人劳动强度，也解决了原来使用铜管材质的供气载体易出现漏铁水的问题。经试验一块透气砖可连续使用至120次‑180次，远高于铜管的30次‑50次的使用寿命，性价比远高于用铜管材质的供气载体。
