日本一家钢铁公司发明了一种转炉出钢新技术———“密封出钢法”。密封设备主要是两个法兰盘 ,一个焊接在转炉出钢口上 ,另一个焊接在钢包盖上。法兰盘用钢板压制而成 ,并砌有耐火砖。出钢时两个法兰盘能密封合在一起 ,从而保证钢水从转炉出钢口流入钢包内。平时出钢口用挡渣? A Japanese steel company invented a new converter tapping technology --- “sealed tapping method.” The main sealing equipment is two flanges, one welded on the tapping hole of the converter and the other on the ladle lid. Flange made of steel pressed, and bricklaying bricks. When tapping, the two flanges can be sealed and sealed together to ensure that the molten steel flows into the ladle through the tapping hole of the converter. Usually tapping with tapping?
