Abstract
The utility model discloses a rapid spraying gun for spraying powder in molten iron. The spraying gun disclosed by the utility model comprises a spraying pipe and a high temperature-resistant layer which is coated on an external surface of the spraying pipe; the spraying pipe is a straight pipe; a nozzle is arranged at a spraying end of the spraying pipe; a spraying hole of the nozzle can be contracted inwards and expanded outwards; and the middle part of the spraying hole is provided with a throat section. The rapid spraying gun for spraying powder in molten iron disclosed by the utility model has the advantages of being simple in structure, convenient to use, good in high temperature-resistant effect and high in spraying speed; and the time for using the spraying gun in the molten iron is reduced, the service life is prolonged, and the number of times for reusing the spraying gun disclosed by the utility model is at least 100 more than the number of times for using the existing spraying gun.
Description
Technical field
The utility model relates to a kind of spray gun, particularly relates to a kind of spy for the quick spray gun that dusts in molten iron.
Background technology
Molten iron is (desulfurization process) when pre-treatment, need to be by spray gun blowing magnesium base desulfurization powder in the molten iron, and spray gun is in use, needs to insert the molten iron certain depth, then desulfurization powder is blown to molten iron.
For example the patent No. is CN200720184826.3, and publication number is the Chinese patent " spray gun that dusts in the molten iron " of CN201151725.Disclose a kind of spray gun that dusts in the molten iron, this spray gun comprises straight pipe and is coated on the high-temperature-resistant layer of this straight pipe outside surface.The weak point of this patent is, the appearance of high-temperature-resistant layer has been alleviated, and spray gun is not prone to fracture and the phenomenon such as crooked, but in life-time service, only increases high-temperature-resistant layer, and effect is not also best, and jet velocity is slow.
The utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, proposes a kind of quick spray gun for dusting in molten iron.The utility model adopts and sets up nozzle in the ejection end of jet pipe, and set up nickel base alloy layer between high-temperature-resistant layer and jet pipe, overcome prior art and had the undesirable technical problem of high temperature resistant situation, simple in structure, easy to use, high-temperature resistant result is good, jet velocity is fast, reduced the time of using in molten iron, extended work-ing life, reused number of times than existing spray gun and Duo at least more than 100 times.
The utility model is realized by the following technical solutions:
A kind of quick spray gun for dusting in molten iron comprises jet pipe and the high-temperature-resistant layer that is coated on the jet pipe outside surface, and described jet pipe is straight tube, it is characterized in that: the ejection end of described jet pipe is provided with nozzle, and the spray orifice of described nozzle is for inside contracting the formula of extending out, and there is throat's section the centre.
Be provided with nickel base alloy layer between described jet pipe and high-temperature-resistant layer.
Described high-temperature-resistant layer is to mix by bauxites aggregate, brown corundum and white fused alumina the high-temperature-resistant layer that consists of.
The utility model compared with prior art, its advantage is:
1, the utility model adopts and sets up nozzle in the ejection end of jet pipe, and set up nickel base alloy layer between high-temperature-resistant layer and jet pipe, overcome prior art and had the undesirable technical problem of high temperature resistant situation, simple in structure, easy to use, high-temperature resistant result is good, jet velocity is fast, reduced the time of using in molten iron, extended work-ing life, reused number of times than existing spray gun and Duo at least more than 100 times.
2, the utility model employing high-temperature-resistant layer is to mix by bauxites aggregate, brown corundum and white fused alumina the high-temperature-resistant layer that consists of; Can form thick high temperature material, result of use is good.
3, the utility model adopts the ejection end of jet pipe to be provided with nozzle, and the spray orifice of nozzle is for inside contracting the formula of extending out, and there is throat's section the centre; Increase ejection efficiency, reduced the time that spray gun uses in molten iron, also strengthen jeting effect, prevent that magnesium base desulfurization powder from stopping up, and affects the carrying out of desulfurization process.
