Description
Technical field:
The utility model relates to the converter steelmaking utility appliance, particularly automatic oxygen rifle slag scraper.
Background technology:
The oxygen rifle is one of the key equipment in top-blown oxygen converter workshop.It finishes the work that blows oxygen in converter.During blowing, the oxygen rifle that links to each other with oxygen supply pipe in the workshop is driven by lifting device and sends in the burner hearth, on the certain altitude of distance metal pool surface with the high speed oxygen gas blowout to high temperature fluent metal, realize the smelting of metal pool.When smelt finishing blow off, the oxygen rifle is driven by lifting device and rises, and cuts off oxygen during to certain altitude automatically, and after the oxygen rifle was extracted out in the stove, converter just can be carried out other operation.Top-blown oxygen converter certainly will produce explosive splash, metal splash and foamy slag splash etc. in converting process.Splash causes oxygen rifle head dry slag, and oxygen rifle weight is increased, and the rifle area of bed strengthens, if untimely cleaning, the oxygen rifle scratches equipment such as oxygen muzzle easily maybe can't transfer to the oxygen muzzle, and normal smelting of influence produced.Be to adopt artificial scarfing cinder operation before this.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and the automatic oxygen rifle of a kind of converter slag scraper is provided.
Scheme of the present utility model is: slag scraper is made up of base, cylinder, guide holder, orienting sleeve, U type frame, dreg scraping wheel, and base is a rectangular frame, and cylinder, guide holder are fastened on forward and backward half pedestal of base by bolt respectively; Guide holder is the annulus column, and extending to both sides and the side platform in its bottom, is fixed on the base by side platform bolt hole, and round bottom portion is fixed with vertical square key in the guide holder; Orienting sleeve is a right cylinder, the bottom has keyway, circle and square key are longitudinal motion state movingly in orienting sleeve external diameter and width of keyway and the guide holder, the orienting sleeve rearward end extends and the U template, U template biside plate offers medium pore, after cylinder piston rod front end web plate inserts U template hollow, implements to connect with bearing pin, the orienting sleeve front end is provided with the step right cylinder, and this step right cylinder is provided with outside screw; U type frame is that extend and biside plate in both sides at the bottom of the disk, offers medium pore on the end disk, after this borehole jack is combined in orienting sleeve step right cylinder, implements fixedly connectedly with nut locking step right cylinder outside screw, offers the corresponding central hole on the U type frame biside plate; Dreg scraping wheel is that the disc radial equipartition that offers medium pore outwards extends and six cuboid teeth, two dreg scraping wheels are lined with sleeve in the middle of being fitted in U type frame biside plate inboard, and bearing pin passes biside plate, two dreg scraping wheels, sleeve corresponding aperture movingly and implements to be located by connecting.
Advantage of the present utility model is: the one, reach automatic slag removal, and reduce the purpose of labor strength; The 2nd, protected equipment such as oxygen rifle and oxygen muzzle well, improve their work-ing life; The 3rd, save the oxygen rifle scarfing cinder time, improve the production efficiency of converter.

Fig. 3 is the utility model working state figure.
Embodiment:
Structure of the present utility model comprises cylinder (1), it is characterized in that also comprising base (8), slag scraper is made up of base (8), cylinder (1), guide holder (3), orienting sleeve (2), U type frame (4), dreg scraping wheel (6), base (8) is a rectangular frame, and cylinder (1), guide holder (3) are fastened on forward and backward half pedestal of base (8) by bolt respectively; Guide holder (3) is the annulus column, and extending to both sides and the side platform in its bottom, is fixed on the base (8) by side platform bolt hole, and the interior round bottom of guide holder (3) portion is fixed with vertical square key (7); Orienting sleeve (2) is a right cylinder, the bottom has keyway, circle and square key (7) are longitudinal motion state movingly in orienting sleeve (2) external diameter and width of keyway and the guide holder (3), orienting sleeve (2) rearward end extends and the U template, U template biside plate offers medium pore, after cylinder (1) piston rod front end web plate inserts U template hollow, implement to connect with bearing pin, orienting sleeve (2) front end is provided with the step right cylinder, this step right cylinder is provided with outside screw U type frame (4) and extends for both sides at the bottom of the disk and biside plate, offer medium pore on the end disk, after this borehole jack is combined in orienting sleeve (2) step right cylinder, fixedly connected with the enforcement of nut locking step right cylinder outside screw, offer the corresponding central hole on U type frame (4) biside plate; Dreg scraping wheel (6) six cuboid teeth for the disc radial equipartition that offers medium pore outwards extends, two dreg scraping wheels (6) are fitted in and are lined with sleeve (5) in the middle of U type frame (4) the biside plate inboard, and bearing pin passes biside plate, two dreg scraping wheels (6), sleeve (5) corresponding aperture movingly and implements to be located by connecting.
Because it is more open that the slag that is bonded in the oxygen rifle is organized, its hardness is higher, and fragility is big, very easily comes off under pressurized or situation about being hit.Therefore two oxygen rifle slag scrapers are installed in top-blown oxygen converter gasification cooling flue oxygen muzzle top correspondence position in opposite directions, after the oxygen rifle is finished blowing and proposed the oxygen rifle, carry in the continuation and start oxygen rifle slag scraper and hold the oxygen rifle tightly the oxygen rifle is scraped slag; After scraping slag, unclamp oxygen rifle slag scraper, start the height that the oxygen rifle drops to be needed.If will also scrape slag then continues aforesaid operations, till the slagging scorification on the oxygen rifle being scraped totally.Concrete principle of work is as follows: the oxygen rifle is in putting forward the process of rifle, and the cylinder (1) that is distributed in oxygen rifle both sides clamps, and makes slag be subjected to the extruding of the scarfing cinder gear teeth, cutting and fragmentation comes off.Its automatic control program course of action is as follows: the shared cover dross extractor of A rifle and B rifle, dross extractor can be respectively in master control room and the other operation of machine.When the needs scarfing cinder, can click the scarfing cinder system selector switch on the master control computation picture, at this moment,, need only " carrying rifle " button on the clicking operation platform so if in the master control room scarfing cinder, dross extractor cylinder (1) clamps, the beginning scarfing cinder.When stopping to carry rifle, dross extractor cylinder (1) opens, and finishes scarfing cinder.If in the other scarfing cinder of machine, as long as " carrying rifle " button on the other operation box of operating machine, dross extractor cylinder (1) clamps the beginning scarfing cinder.When stopping to carry rifle, dross extractor cylinder (1) opens, and finishes scarfing cinder.This oxygen rifle slag scraper Controlling System is provided with position and tension limit protection.Have only when the oxygen rifle mentioned " holding point " when above and left side or right steel wire rope tension and be no more than 8000kg, just allow scarfing cinder, otherwise do not allow scarfing cinder.
The oxygen rifle is distributed in cylinder (1) action of oxygen rifle both sides in putting forward the process of rifle, promote the tail rod cover and drive dreg scraping wheel (6) slag of implementing on tooth extruding, the cutting oxygen gun barrel that moves ahead its fragmentation is come off, and reaches the purpose of automatic slag removal.It scrapes slag power is the squeeze that clamps cylinder (1) from one, the 2nd, and the lifting force of oxygen rifle lifting gear.
Between cylinder (1) and guide holder (3), be provided with the dw that is fixed in base (8).Play dust prevention at the converter upper space to the piston rod extendable room.
