Description
Technical field
The utility model relates to the equipment that uses in the metallurgical technology, and that particularly uses during the metallurgical melt bottom blowing refining two-mans ladle.
Background technology
In metallurgy industry, smelt the metal melt that and generally be placed on earlier and two-man ladle, before solidification of metal melt,, just need carry out refining in order to improve the quality of metal product.What the purified mode was often used generally has following three kinds: top blast refining, side-blown refining, bottom blowing refining.Melt takes place when the top blast refining easily spill accident, bad control; The side-blown refining then descends owing to the bottom melt stirs the inhomogeneous quality product that causes, deficiency in economic performance, and do not adopt; Bottom blowing refining stirs melt good advantage, to improving the metal product quality obvious effects is arranged, and in actual production, the general methods of bottom blowing refining that adopt are carried out refining to metallurgical melt more.And during the bottom blowing refining that uses in metallurgy industry at present two-mans ladle, has only a nozzle, find that in actual production this design exists defective, at first be that the bottom blowing refining of a nozzle is two-mand ladle can produce the dead angle that melt stirs in actual production, melt quality is inhomogeneous in causing two-maing ladle, and influences final quality product; Secondly, because existing bottom blowing refining is two-mand ladle and had only a nozzle, cause the time of bottom blowing refining longer, the melt calorific loss is more, influences output, thereby increases the energy consumption of unit product.
Summary of the invention
The purpose of this utility model is intended to overcome the defective of prior art, provides that a kind of refining time is short, the melt calorific loss is few, no melt stirring dead angle, and the refining melt quality is even, and the output height has multi-jet bottom blowing refining and two-mans ladle.
Bottom blowing refining described in the utility model is two-mand ladle, constitute by the inclusion of two-maing ladle, refining blowing system, gas voltage balancer, the inclusion of two-maing ladle is a back taper, ventpipe is connected with the gas voltage balancer, refining blowing system has at least three steel pipes, every steel pipe connects at least one nozzle, is that the center of circle is radial equidistant arrangement and forms with the gas voltage balancer.
At least can connect two on the every steel pipe with upper spray nozzle, form two-layer structure at least.Nozzle location can be adjusted in the center of two-maing ladle and the radius of two-maing ladle.The quantity of described steel pipe can many, and the nozzle of contacting on the described steel pipe can be a plurality of, and forming with the gas voltage balancer is the center of circle, and many steel pipes and a plurality of nozzles on it of contacting are the radial platform bag bottom that radially is covered with and exceed.
Described nozzle, in the wall of two-maing ladle of steel plate system, be lined with asbestos plate, the nozzle that has gas permeable brick to constitute on the asbestos plate, gas permeable brick is positioned at the mid-way, refractory brick is arranged around the gas permeable brick, scribble fire-resistant coating on refractory brick, an end of gas permeable brick is to the bottom bottom blowing refining metallurgical melt of two-maing ladle, and the other end passes asbestos plate by steel pipe and is connected with the gas voltage balancer with the furnace wall.
Described fire-resistant coating is heat-resisting concrete knotting layer.
Bottom blowing refining described in the utility model is two-mand ladle, radial bottom blowing refining scavenger system is installed in the bottom of two-maing ladle, gas permeable brick directly contacts with metallurgical melt by the bottom of two-maing ladle, gas permeable brick is made by common refractory and is got final product, connect by steel pipe between each nozzle, refining blowing system and gas voltage balancer are also by steel pipe UNICOM, the furnace wall welding of one end of steel pipe and gas permeable brick bottom steel plate system, the other end welds with the gas voltage balancer of the bottom centre position of two-maing ladle, the gas voltage balancer is welded by general steel plate, after the gaseous tension homogenizing that portion enters ventpipe, make gas equate that at the pressure of inner each position of voltage balancer the gas that leads to each nozzle is all pressed within it, the quality that realizes metallurgical melt inside is even, toward the melt internal ventilation, the dynamic conditions of melt is good, stirs simultaneously for a plurality of nozzles, there is not the dead angle, can effectively shorten refining time, the melt calorific loss is few, can enhance productivity.
