摘要： A process and apparatus to clean refractory-lined conveyor troughs for molten metals and slags by means of chains on a rotating drum. A motor is used to drive the drum, whose current consumption and/or speed are variable as a function of the load. Variation from a specified setpoint is used to cause a displacement of the rotating drum transverse to the conveyor trough, to achieve optimal cleaning of the trough wall, which is only effected with the desired distance between wall and drum and a load on the motor corresponding to this distance. The direction of rotation of the drum is reversible, so that when the two sides of the conveyor trough are cleaned, the material removed is thrown in the same direction, preferably towards a suction exhaust.

摘要： A runner for hot metal as from a blast furnace is formed of a series of interconnected modular units which are prefabricated, preferably from refractory based materials. A plurality of flat slab-like covers are positioned continuously on the runners formed of the interconnected modular units so as to confine fumes, gas, smoke and other air pollutants. Live steam is introduced at selected locations along the runners to collect, absorb and mix with the fumes, gases and air pollutants. Vacuum devices in communication with the covered runners remove the air, steam and pollutants and direct them through scrubbers and/or precipitron equipment to remove the air pollutants before the air entrained in the system is released to the atmosphere.
