电炉炼钢持续稳步的发展,人们所期望的新一代的电弧炉的诞生并非遥远的事。最近西德蒂森(Thyssln)公司已发明了一种新型的电弧炉——炉底出钢复合操作炉(CPF)。它的出钢口设在炉底,炉底出钢系统类似于钢包水口,出钢口用铰链挡板密封,为了防止高温变形,密封处的挡板和出钢通道尾砖均由石墨构成。装料前,用机械从炉门在出钢通道中填以中等粒度的干耐火 The steady and steady development of EAF steelmaking is not far off as the birth of a new generation of EAF. Recently, Thyssln has invented a new type of electric arc furnace-bottom tapping compound operation furnace (CPF). Its tapping hole is set at the bottom of the furnace. The tapping system at the bottom of the furnace is similar to the ladle tapping hole. The tapping hole is sealed with a hinge baffle. In order to prevent the deformation at high temperature, the baffle of the sealing part and the tailed bricks of the tapping channel are made of graphite. Prior to loading, machinery was used to fill dry-out channels with medium-grain dry fire resistance from the furnace door
