Abstract
The utility model relates to a forging warm-extrusion oxygen lance nozzle which comprises a nozzle cap, a water blocking plate, a nozzle outer pipe, a nozzle upper portion, a nozzle middle pipe, a nozzle oxygen pipe and an O-shape sealing ring. Compared with oxygen lance nozzles in the prior art, the forging warm-extrusion oxygen lance nozzle has the advantages that the cost is low, design is reasonable, machining is convenient, and the practicality is high; the structure of the nozzle cap is molded for one step through warm-extrusion forging, so that nozzle cap metal fibers are continuous, the grain size is small, the oxygen content is low, the copper purity is high, the heat conductive property is good, the anti-deformation capacity is high, and the service life is long; and simultaneously, the nozzle is brazed to be integrated after machining, so that inner surfaces of the nozzle outer pipe and the nozzle middle pipe are smooth, the water flow resistance is small, the nozzle is cooled effectively through cooling water, and the integral technical performance of the nozzle is improved greatly.
Description
Technical field
The utility model relates to the oxygen blowing apparatus of steelwork converter steel-making use, particularly a kind of forging and pressing warm extrusion formula oxygen lance blow head.
Background technology
in converter steelmaking, the top oxygen blast is the critical process of steelmaking process, each steel mill is for improving output in recent years, reduce costs, by converter is undergone technological transformation, larger raising the tonnage of converter, also more and more higher to the requirement of oxygen rifle simultaneously, at present, the cast type oxygen lance blow head that generally uses, because the purity of cast copper is low, oxygen level is high, coarse grains, poor thermal conductivity and casting shower nozzle rough inner surface, the water-cooled effect is undesirable, finally make casting shower nozzle high thermal resistance and non-deformability poor, work-ing life is low, the unstable grade of smelting performance has limited the raising of oxygen rifle technical feature.
Summary of the invention
The purpose of this utility model is to provide that a kind of cost is low, the forging and pressing warm extrusion formula oxygen lance blow head of long service life, raising cooling performance.
For achieving the above object, the utility model is realized by the following technical solutions:
a kind of forging and pressing warm extrusion formula oxygen lance blow head, comprise the shower nozzle pileum, water eliminator, the shower nozzle outer tube, shower nozzle top, manage in shower nozzle, shower nozzle oxygen pipe and O shape rubber seal, described shower nozzle top one end is connected with the shower nozzle pileum by jointed connecting rod, shower nozzle pileum surface is provided with hole, taper Lavalle, hole, Lavalle and shower nozzle top formation gas channel, the shower nozzle top the other end is connected with shower nozzle oxygen Guan Yiduan, the shower nozzle oxygen pipe the other end is provided with O shape rubber seal, the shower nozzle oxygen pipe outside is connected with pipe in shower nozzle by water eliminator, in shower nozzle, the pipe outside is provided with the shower nozzle outer tube, shower nozzle oxygen pipe, in shower nozzle, pipe and shower nozzle outer tube form cooling water channel.
Hole, described Lavalle has 3～6, is evenly distributed on the shower nozzle pileum surperficial.
Described water eliminator and shower nozzle oxygen pipe are welded and fixed.
Described water eliminator is threaded with pipe employing in shower nozzle.
Described shower nozzle pileum is warm extrusion once shaped structure.
Compared with prior art, the beneficial effects of the utility model are:
A kind of forging and pressing warm extrusion formula oxygen lance blow head, have low, reasonable in design, easy to process, the practical characteristics of cost, the shower nozzle pileum is warm extrusion once shaped structure, make shower nozzle pileum steel fiber continuous, grain fineness number is little, oxygen level is low, copper purity is high, and thermal conductivity is good, and resistance type ability is strong, life-span is high, the machined rear soldering combination of this shower nozzle simultaneously, and then in shower nozzle outer tube and shower nozzle, pipe internal surface is smooth, flow resistance is little, guarantee that water coolant carries out shower nozzle effectively cooling, the overall technology performance of this shower nozzle is improved greatly.
Description of drawings
Fig. 1 is structure iron of the present utility model;
Fig. 2 is use schematic diagram of the present utility model.
Manage in 13-oxygen rifle oxygen pipe, the 14-oxygen rifle of hole, 8-jointed connecting rod, 9-shower nozzle outer tube, 10-water eliminator, 11-shower nozzle pileum, 12-Lavalle, 7-shower nozzle top in 1-cooling-water flowing outlet, 2-cooling-water flowing entrance, 3-hyperbaric oxygen import, 4-O-ring seals, 5-shower nozzle oxygen pipe, 6-shower nozzle and manage 15-oxygen rifle outer tube
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
as shown in Figure 1, a kind of forging and pressing warm extrusion of the utility model formula oxygen lance blow head, comprise shower nozzle pileum 11, water eliminator 10, shower nozzle outer tube 9, shower nozzle top 7, manage 6 in shower nozzle, shower nozzle oxygen pipe 5 and O shape rubber seal 4, shower nozzle top 7 one ends are connected with shower nozzle pileum 11 by jointed connecting rod 8, shower nozzle pileum 11 surfaces are provided with hole, taper Lavalle 12, hole, Lavalle 12 forms gas channels with shower nozzle top 7, shower nozzle top 7 the other ends are connected with shower nozzle oxygen pipe 5 one ends, shower nozzle oxygen pipe 5 the other ends are provided with O shape rubber seal 4, shower nozzle oxygen pipe 5 outsides are connected with pipe 6 in shower nozzle by water eliminator 10, in shower nozzle, pipe 6 outsides are provided with shower nozzle outer tube 9, shower nozzle oxygen pipe 5, in shower nozzle, pipe 6 and shower nozzle outer tube 9 form cooling water channel, hole, Lavalle 12 has 3～6, be evenly distributed on shower nozzle pileum 11 surfaces, water eliminator 10 is welded and fixed with shower nozzle oxygen pipe 5, water eliminator 10 is threaded with pipe 6 employings in shower nozzle.
As shown in Figure 2, when using the utility model, at first the oxygen rifle is connected with shower nozzle, then high pressure oxygen enters shower nozzle by hyperbaric oxygen import 3 and shower nozzle oxygen pipe 5 successively, 12 ejections enter steel-smelting furnace from the hole, Lavalle again, water coolant manage from shower nozzle 6 and shower nozzle oxygen pipe 5 between cooling-water flowing entrance 2 enter shower nozzle, then through water eliminator 10 bottom the shower nozzle, cooling-water flowing outlet 1 from shower nozzle between pipe 6 and shower nozzle outer tube 9 is flowed out, and shower nozzle is obtained cooling.
Above-mentioned shower nozzle pileum 11 selects Tu1 oxygen free copper through the forging base, then carries out warm extrusion with mould, and once shaped.
