Abstract
The utility model relates to a novel multi-taper pyramidal oxygen lance for converting, which comprise a nozzle, an outer tapered pipe, an outer thick and straight pipe, an outer reducer pipe, an outer pipe of lance which is welded in an integration, and an inner pipe of oxygen lance and a middle-layer pipe of oxygen lance; The utility model is characterized in that: an outer coat of middle-layer pipe with certain taper is arranged on the pyramidal part of the outer tapered pipe which is corresponding to the outer of the middle-level pipe of oxygen lance, and is fixed with the middle-layer pipe by sealing. The utility model has the advantages that: the problem of a paste lance for the oxygen lance can be solved, the assembly and maintenance for the outer coat of the middle-layer pipe can be simplified.
Description
Technical field
The utility model relates to novel many taperings oxygen lance with conical that converter steelmaking is used.
Background technology
At present, converter oxygen gun mostly is straight rifle, and the body of a gun is made up of three layers of sleeve pipe.The oxygen rifle is in converting process, and the body of a gun unavoidably will adhere to slag.The body of a gun adheres to slag, can make the oxygen rifle can not carry oxygen rifle hole when serious and is forced to burning torch, remove sticking rifle and be one of the workman not only arduous but also dangerous work, delays the steel-making activity duration simultaneously again, influences output of steel, the cost of increase steel.Normally, stablize molten iron temperature, composition, improve measures such as slag making operation and oxygen-supply operation and alleviated by improving the slag charge quality.
The best approach that solves the sticking rifle of oxygen rifle is to adopt oxygen lance with conical, be about to oxygen rifle bottom and adopt the taper outer tube of different taperings, make slag fail to stick or come off voluntarily through cooling and to slip in the stove, be to guarantee the cooling intensity of oxygen lance with conical, also be designed to taper corresponding to the oxygen rifle middle tube of outer conical part.
The tapering of tapered tube is big more, the effect of sticking rifle is not good more, but is limited to the working method of oxygen rifle hole dimension and tapered tube and the restriction of cost, makes cone pipe tapering can not do too greatly again, the assembling of the tapered tube in middle level welding simultaneously and maintenance are very difficult, and this is the subject matter that present cone rifle exists.
Summary of the invention
The purpose of this utility model provides a kind of novel many taperings oxygen lance with conical, and this oxygen rifle is provided with the middle tube overcoat of band tapering in the middle tube outside, makes assembling and maintenance simple greatly, convenient; And adopt the outer tapered tube of the different taperings of multistage to weld together, solved sticking rifle problem.
Novel many taperings oxygen lance with conical, pipe and oxygen rifle middle tube constitute in the oxygen rifle outer tube that is welded as a whole successively by shower nozzle, outer tapered tube, outer thick straight tube, outer adapter bonnet, body of a gun outer tube, the oxygen rifle; It is characterized in that: corresponding to the cone position of outer tapered tube, be provided with the middle tube overcoat of certain taper in the outside of oxygen rifle middle tube, and with the middle tube sealing and fixing.
Described outer tapered tube length is 3-6 rice; Outer tapered tube is welded together by multistage, the tapering difference of each section, and each tapering is in 16 " to 5 ° 30 " scope.
The thick length of straight pipe of described skin is 1～4 meter.
The beneficial effects of the utility model are: can effectively solve the sticking rifle problem of oxygen rifle, convenient greatly again simultaneously assembling and the maintenance of simplifying the middle tube overcoat.
Description of drawings
Fig. 1 is the structural representation of novel many taperings oxygen lance with conical.
Embodiment
See Fig. 1, novel many taperings oxygen lance with conical, by shower nozzle 1, outer tapered tube 2, outer thick straight tube 6, outer adapter bonnet 7, body of a gun outer tube 3 is welded as a whole successively and the oxygen rifle in manage 5, oxygen rifle middle tube 4 constitutes; Corresponding to the cone position of outer tapered tube 2, be provided with the middle tube overcoat 8 of certain taper in the outside of oxygen rifle middle tube 4, and with the middle tube sealing and fixing.
According to the difference of converter size, outer tapered tube 2 length are 3-6 rice; According to sticking rifle degree difference, outer tapered tube divides a, b, c and d to weld together for four sections, this tapering difference of four sections, and its tapering is in 16 " to 5 ° 30 " scope.
Thick straight tube 6 length of described skin are 1～4 meter.
Claims (3)
