Abstract
The utility model relates to a hot metal pretreatment tool of a blast furnace in a steel mill, namely a durable spray gun for hot metal pretreatment, which comprises a gun body and a gasification chamber at the lower part of the gun body, wherein the gasification chamber comprises inner and outer surfaces formed by heat-resisting steel frameworks and poured fire-resisting material. In the utility model, the integral alloy steel structure of the gasification chamber is abandoned, instead, the frameworks welded by the heat-resisting stainless steel bars are poured into the gasification chamber formed by the fire-resisting material; the steel bars inside the fire-resisting material are not in direct contact with the hot metal and are not easily burned through by the hot metal, so that the service life of the durable spray gun provided by the utility model is long and the cost is low; and the life span can usually reach up to more than 200 times, that is more than 3 times compared with the common spray guns, so that the production requirements can be fully satisfied.
Description
Technical field
The utility model relates to the blast-melted pretreating tool of a kind of steel mill, promptly a kind of hot metal pretreatment long-service-life spray gun.
Background technology
In the prior art, the molten iron that molten iron is filled with in steel mill is irritated when entering the desulfurization station, spray gun just penetrates in the molten iron of iron ladle in orbit, and high pressure nitrogen ejection deactivating magnesium powder reacts the sulphur in itself and the molten iron, produces high steel alloy of purity and high-quality steel after making molten iron purification.Molten iron desulfuring spray gun is made of the vaporizer of rifle body and its underpart, and vaporizer is processed the integrally welded in-mold molding of using mould material in special use again in back with steel alloy processing, uses after toasting.There is the refractory materials protection in the vaporizer outside; the inboard directly contacts with high temperature liquid iron; its shortcoming is the high temperature liquid iron because of about 1400 ℃ of frequent contacts; often the steel alloy vaporizer is burnt out; can't use, have to renew spray gun, general work-ing life is about 60 times; life-span is short, cost is high, can not satisfy the production needs.
The utility model content
The purpose of this utility model is to provide a kind of improvement structure, the hot metal pretreatment long-service-life spray gun of long service life at above-mentioned deficiency.
Technical solution of the present utility model is: hot metal pretreatment long-service-life spray gun comprises the vaporizer of rifle body and its underpart.Vaporizer is made of the about face that the refractory materials of high temperature steel skeleton and cast forms.High temperature steel is stainless steel, carbon steel or steel alloy.
The utility model has the advantages that: changed the whole structure of vaporizer with steel alloy, be welded into skeleton with the heat-resistance stainless steel muscle, be cast in the vaporizer of refractory materials formation, the invar muscle does not directly contact with molten iron in refractory materials, is difficult for being ablated by molten iron, life-span is long and cost is low, generally can reach more than 200 times, improve the life-span more than 3 times, can meet the needs of production fully than general spray gun.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is a high temperature steel skeleton structure sketch.
Embodiment
Referring to Fig. 1, hot metal pretreatment long-service-life spray gun comprises the hydraucone shape vaporizer 2 of rifle body 1 and its underpart.Vaporizer 2 is made of stainless steel insert 3 and the about face 5,6 that the refractory materials of pouring into a mould forms.
Referring to Fig. 2, stainless steel insert 3 surrounds the hydraucone shape at interval by longitudinal and transverse stainless reinforcing bar 7,8.
Claims (2)
1. hot metal pretreatment long-service-life spray gun comprises the vaporizer (2) of rifle body (1) and its underpart, it is characterized in that about face (5, the 6) formation that vaporizer (2) is formed by the refractory materials of high temperature steel skeleton (3) and cast.
2. according to the described hot metal pretreatment long-service-life spray gun of claim 1, it is characterized in that high temperature steel skeleton (3) surrounds the hydraucone shape at interval by longitudinal and transverse high temperature steel reinforcing bar (7,8).
