| 摘要 |
An electric steel-making furnace has a furnace roof carried by an upper furnace shell on a lower furnace shell to substantially envelop an atmosphere above liquid steel and slag floating thereon in the lower furnace shell. A transfer car supports the lower furnace shell for transport from a furnace-operating site to a remote exchange site for exchanging one or more of the furnace roof, the upper furnace shell and the lower furnace shell. The furnace transfer car has a furnace support platform engaged with the lower furnace shell and supported for tilting of the furnace on the transfer car by actuators at the furnace operating site in a direction to increase the depth of slag at the deslagging passageway for decanting slag floating on liquid steel in the lower furnace shell. Actuators are also provided to tilt the furnace on the transfer car to increase the depth of liquid steel at a tap hole assembly during tapping of a steel heat.
