单词	basic-oxygen process
释义	basic-oxygen process(BOP process) A high-speed method of making high-grade steel. It originated in the Linz—Donawitz (L-D process ). Molten pig iron and scrap are charged into a tilting furnace, similar to the Bessemer furnace except that it has no tuyeres. The charge is converted to steel by blowing high-pressure oxygen onto the surface of the metal through a water-cooled lance. The excess heat produced enables up to 30% of scrap to be incorporated into the charge. The process has largely replaced the Bessemer and open-hearth processes
