钢铁联合企业中高炉不仅一直承担生铁的供应,而且近年来还起着向钢铁厂提供伴生煤气的能源基地作用。高炉一旦点火,就会在寿命期内一直提供生铁和伴生煤气,但是每当炉役寿命结束,就要停炉进行大修,然后再行点火。由于在大修期间会停止生铁和伴生煤气的供应,因而对于钢铁厂来说 In the steel conglomerate, blast furnaces have not only been responsible for the supply of pig iron, but have also played a role as an energy base for supplying associated gas to steel mills in recent years. Once the blast is ignited, pig iron and associated gas will be supplied for the life of the blast furnace.
