The invention discloses an iron alloy heating furnace and an iron alloy supply device. The iron alloy heating furnace comprises a heating furnace body, the furnace wall of the heating furnace body is of a single-layer structure, a furnace cover is arranged above the heating furnace body, a receiving opening is formed in the furnace cover and inserted into the furnace cover, the furnace cover is further provided with a dust removal pipe parallel to the receiving opening, the upper portion of the heating furnace body is provided with a flame monitor device hole and an artificial viewing hole formed below the flame monitor device hole, the heating furnace body is further provided with a thermocouple, the lower portion of the heating furnace body is at least provided with a layer of burners evenly distributed around the heating furnace body, and a sector-shaped discharging valve is installed below the heating furnace body. By the adoption of the iron alloy heating furnace of the structure and the iron alloy supply device, the problems that an iron alloy heating furnace is complex in structure, an iron alloy supply device is complex and large in equipment investment, the iron alloy heating temperature is low, and quantitative and constant-temperature heating cannot be achieved can be solved.
Description
technical field [0001] The invention belongs to the technical field of ferroalloy supply in converter steelmaking, and in particular relates to a ferroalloy heating furnace and a ferroalloy supply device. Background technique [0002] When making steel in the converter, according to the batching requirements, first put scrap steel into the furnace, then pour molten iron, and add an appropriate amount of slagging material, blow oxygen into the converter, and the oxygen will react with the high-temperature molten iron to remove the molten iron. After removing most of the sulfur and phosphorus in the molten steel, the oxygen blowing is stopped after the temperature of the molten steel reaches the requirement, and then the molten steel in the converter is injected into the ladle, and the ferroalloy weighed according to the composition requirements is added into the ladle, and then put into the ladle Carry out deoxidation alloying, and after the molten steel is qualified, it is c...
