The advantages of the utility model lies in that the through the respective design and processing technology of every part of the nozzle, the utility model has a good water cooling effect, a long service life and a good metallurgy effect.
Description
The utility model relates to the oxygen blowing apparatus that uses in a kind of oxygen converter steelmaking, particularly a kind of oxygen lance blow head.
In oxygen converter steelmaking, oxygen supply is the essential factor in the converting process, and for this reason, the technical feature of its oxygen supply equipment oxygen lance blow head needs metallurgical effect preferably, higher wearing quality and non-deformability.Prior art cast type oxygen lance blow head is the one-piece construction with 4 oxygen spraying holes, and its shower nozzle center has water-cooling structure, and the shower nozzle that is under the high-temperature work environment is had water-cooled effect preferably, is widely used in converter steelmaking.But the deficiency of its existence is, its spray orifice and oxygen rifle medullary ray angle are less, when oxygen-supplying amount is big, each strand of spray orifice oxygen jet arrive can form before the bath surface overlapping, thereby form unnecessary splash; Simultaneously, its one-piece construction is that the design and the manufacturing of desired shower nozzle technical feature increased difficulty, has limited the raising of shower nozzle technical feature.Shower nozzle is lower work-ing life.
The purpose of this utility model provides a kind of built-up type oxygen lance blow head, and it is convenient to design and makes, and the shower nozzle technical feature is better than above-mentioned cast type one-piece construction oxygen lance blow head.
The utility model is achieved in that this oxygen lance blow head is a tubular structure, its structure ecto-entad is assembled by outer tube, middle pipe, three layers of pipe fitting of feeding oxygen tube successively, outer tube is welded to connect with the single-piece formation that is called as the shower nozzle bottom, be evenly distributed with 5 oxygen spraying holes (abbreviation spray orifice) on the garden Zhou Fangxiang of the garden shape curved surface bottom shower nozzle, corresponding to each spray orifice, have with the spray orifice periphery and be connected as a single entity, and upwardly extending tubulose spray orifice expansion segment (being called for short the spray orifice expansion segment), this shower nozzle bottom is made by the fine copper forging and pressing; In outer tube, locate near the shower nozzle bottom, the plate-like water diversion disk (abbreviation water diversion disk) that water coolant is carried out water conservancy diversion is installed, shape card center, water diversion disk garden has the cooling-water flowing through hole, its shape card garden, garden Zhou Fangxiang has the corresponding through hole of spray orifice expansion segment with the shower nozzle bottom, by this through hole, water diversion disk forms nested the connection with shower nozzle bottom spray orifice expansion segment, the outer of water diversion disk is threaded with middle pipe formation, be somebody's turn to do between middle tube wall and the feeding oxygen tube tube wall, and constitute the cooling-water flowing circulation passage between middle tube wall and the outer tube wall; Feeding oxygen tube has the bottom surface of sealing, its bottom surface is distributed with and the corresponding through hole of shower nozzle bottom spray orifice expansion segment, this bore periphery and tubulose aditus laryngis Duan Yiduan formation are welded to connect, the tubulose aditus laryngis section the other end and shower nozzle bottom spray orifice expansion segment formation are welded to connect, and form the oxygen channel of each spray orifice of shower nozzle thus.By adopting said structure, shower nozzle 5 pore structures have increased the angle of spray orifice and oxygen rifle centreline space, thereby make 5 strands of oxygen jets not form overlapping, obviously reduced splash, improved change slag effect, shower nozzle bottom single-piece adopts the design of fine copper and makes the density height of having realized the shower nozzle bottom simultaneously, the performance requriements that thermal conductivity is good, the disk-like structure of water diversion disk has been optimized design, has reduced the cooling-water flow resistance, has further improved the water-cooled effect to shower nozzle.
The utility model has the advantages that reasonable in design is convenient to make, good water-cooling effect, long service life has the good slag characteristic of spattering, and metallurgical effect is good, and is little to the furnace lining etch.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model shower nozzle chart at the bottom of, and wherein Fig. 1-1 is a front view, and Fig. 1-2 is the A-A sectional view of Fig. 1-1.
Fig. 2 is the utility model plate-like water diversion disk structure iron, and wherein Fig. 2-1 is a front view, and Fig. 2-2 is the A-A sectional view of Fig. 1-1.
