摘要： A method of operating a shaft furnace includes inserting a mixture including anthracite coal and coke into a cavity defined by the furnace, and disposing a metal feedstock within the cavity. The method includes injecting natural gas at a natural gas flow rate and a first quantity of oxygen gas at a first oxygen gas flow rate into the cavity simultaneously through at least one burner. The method also includes driving a second quantity of oxygen gas at a supersonic oxygen gas flow rate into the cavity through at least one lance, wherein the supersonic oxygen gas flow rate is greater than the first oxygen gas flow rate. The method also includes combusting the mixture within the cavity to produce a stack gas, melting the metal feedstock to produce a melted metal material, and monitoring the stack gas to thereby operate the shaft furnace. A shaft furnace is also disclosed.

摘要： A hollow cylinder is held in a vertical orientation and sent continuously through a heating zone for sintering. In a first phase of the sintering operation, the hollow cylinder stands on a support while the upper end (12) of the cylinder is being sintered. In a second phase the cylinder hangs from a hanging element while its lower end (10) is sintered. A vertical rod is fixed to the base on which the lower end is supported, and extends through the hollow cylinder. A retaining ring is fixed inside the upper end of the hollow cylinder. During the first phase, the upper end vitrifies and contracts so that the retaining ring engages the vertical rod. Longitudinal contraction causes the lower end to lift off the base so that the cylinder is suspended during the second phase.
