Description
Technical field
The utility model relates to the plumbous body of heater device of a kind of top blow smelting, relates to the service life of lance and the intensified smelting that prolong the top-blown bath melting, is specially a kind of reinforcement Top-blown Lead Smelting body of heater device, belongs to the heavy non-ferrous metal field of metallurgy.
Background technology
The top-submerged lance smelting technique is that a kind of smelting intensity is high, efficiency is high, the winding-up molten pool melting technology of single step smelting lead.Plumbous top blow smelting is top blast submergence melting, belong to the bath smelting category, be widely used in the smelting of non-ferrous metal in lead, the copper, spray gun is the core apparatus of Ai Sa or Ausmelt Smelting method, be the technological core of Top-blown Lead Smelting, its use directly affects smelting process and quality product.The utility model is plumbous for top blow smelting, is applicable to the top blow smelting of various lead-containing materials.
Plumbous top blow smelting carries out in a stationary cylinder shape stove.Add concentrate of lead sulfide ore from stove top, fall into the slag (rich lead skim) that the bottom has some amount, form the high-temperature fusant with solid inclusion.Insert spray gun from the stove top centre, the spray gun termination is immersed in and is mingled with partly the solidifying in the slag of solid, lead sulfide reaction in the oxygen-rich air that spray gun blows out and the slag, and generation is dissolved in the plumbous oxide in the slag.The process evolution of heat, the heat that discharges can make the lead sulfide heat fused of adding.In the slag of melting, lead sulfide and plumbous oxide carry out cross reaction, generate metallic lead.Existing Chinese mugwort Sa or Ausmelt Smelting method, when cross reaction reached balance, lead content was 44% ~ 50% in the slag usually.Reduce lead content in the slag, Ai Sa or Ausmelt Smelting method can't be accomplished.Reduce that lead content can improve slag to the corrosion of spray gun in the slag, improve equipment operation rate, plumbous output capacity improves, and is to strengthen top blow smelting process main attack research direction.
In the Top-blown Lead Smelting process, directly spray into enriched-oxygen air, fuel, melting material and flux to the molten bath by spray gun, simultaneously, the series of physical chemical processes such as strong fusing, oxidation, reduction, slag making occur in furnace charge.The molten bath is subject to spraying into the strong stirring of air-flow, and lead sulfide is converted into plumbous oxide and metallic lead, and the lead bullion of most of output sinks to furnace bottom, and plumbous oxide is dissolved in slag, and slag is on the metal molten bullion.After material lead sulfide all transformed, two-layer about melt is divided in the stove was slag blanket and metal melt layer.At this moment, exist lead bullion, rich lead skim, gas phase three-phase and reach simultaneously equilibrium state between slag and lead bullion, the oxygen gesture is high, and lead content is high in the rich lead skim.On the other hand, owing to plumbous have certain transport property, the continuous distribution of in melt and slag, carrying out along with lead, that is:
Therefore, there is part lead can enter in the slag, reduced plumbous direct yield.For a long time, people seek to improve the method that this plumbous balance is distributed, and attempt improves the plumbous partition ratio that enters lead bullion, improves plumbous direct yield and lead bullion lead tolerance, improves equipment operation rate.
Top-blown spray gun is on “ Zha – metal " between balance can produce important impact, improve structure and the land use reform of spray gun, top blow smelting has been played very important effect.In the top blow smelting process, in the rich, high temperature lead skim under oxidizing atmosphere, complicated galvanic corrosion behavior can occur in spray gun steel outer wall, the electrochemical reactions such as oxidation, sulfuration of metal and slag occur.
During spray gun alloy steel generation thermal etching, the oxide film with provide protection that the surface forms is etched electrochemically in molten slag and is destroyed.Protection top blow smelting spray gun suppresses the corrosion that spray gun is subject to, and improves service life of lance, is the main attack research direction of strengthening top blow smelting.
Summary of the invention
