Abstract
The utility model provides a slag-sticking-proof device for converter oxygen lance, the slag-sticking-proof device for converter oxygen lance is characterized in that a graphite carbon sheath is arranged on the outer tube wall of the oxygen lance. With the utility model, the molten steel and the splashing slag which is produced during the operation of smelting and splashing slag and protecting stove can not be stuck to the body of the oxygen lance, thereby achieving the purpose of preventing the oxygen lance from sticking slag, and multi-pieces and multi-sections circular arc sheath are assembled into the graphite carbon sheath, or multi-sections cylinder sheath are assembled into the graphite carbon sheath. The utility model is easy to be installed and convenient to be changed partially, and can not only reduce the manufacturing cost but also increase productivity effect and ensure the rising of the manufacturing technique and the economic indicator.
Description
Technical field
The utility model relates to a kind of anti-dry slag device, and is especially a kind of in convertor steelmaking process, can prevent the device of block rifle dry slag.
Background technology
Oxygen top blown converter steel making technology has experienced the development of several stages respectively, and three quantum jumps of generally acknowledged contemporary oxygen top blown converter steel making technology are respectively: the change of furnace lining material, the successful Application of continuous casting technology, the breakthrough of Technology of Slag Splashingfor Furnace Maintenance.The process innovation that also has top bottom blowing in addition.The successful Application of these technology makes the multiplication of top-blown oxygen converter smelting technology efficient, and the characteristics fast development fast with its speed, that quality good, adaptability is strong, efficient is high becomes current comparatively advanced process for making.But the converter oxygen gun dry slag problem that has originally existed is not then solved always.Oxygen rifle dry slag is too much overweight, can smelt to converter steelmaking and bring following harm: 1, potential safety hazard is big, present nearly all top-blown oxygen converter smelting technology all is to adopt winding plant to realize the lifting of oxygen rifle, oxygen rifle dry slag too much will increase the load-bearing load of steel cable in the winding plant, serious consequence such as easily cause in the oxygen rifle degeneration stove.2, reduce production efficiency, after damage of oxygen rifle and the serious dry slag steel, must propose the nitrogen closing device to the oxygen rifle so that change the oxygen rifle, otherwise only cut off the oxygen rifle, not only time-consuming but also require great effort, have a strong impact on production efficiency.3, influence the raising of production and technical indication, oxygen rifle dry slag is serious, has reduced the heat size ratio relatively, to making smelting process control difficulty, the splash phenomenon often occurs, makes to blow to decrease increase, calorific loss increase, slag charge consumption increase.4, changed partly processing parameter, otherwise also need peel off cold steel and dry slag on the body of a gun, this is the non routine operation that has no alternative, and generally focuses on, easily like this cause the oxygen rifle to pile mutually to press and be out of shape, thus the influence technique parameter.People work out following three kinds of methods for this reason: 1, coating method, promptly at a kind of high temperature resistant, refractory materials that adhesive power is strong of oxygen rifle surface spraying, but this method is implemented very difficulty, so far till now, does not see the example of successful Application.2, making extraordinary slag, promptly, making slag stronger sticking power not arranged, but this method do not conform to modern oxygen top blown converter steel making processing requirement, can not implement with the oxygen rifle by reduce smelting viscosity coefficient of dross and basicity.3, dregs scraper method promptly is provided with dregs scraper at oxygen rifle nitrogen closing device place, when smelt finishing the oxygen rifle is proposed the nitrogen closing device, and dregs scraper scrapes the dry slag on the body of a gun, thereby avoids oxygen rifle dry slag, but that it scrapes power is limited, restive.Therefore, be necessary fully prior art is improved.
Summary of the invention
Be difficult to deficiencies such as raising for overcoming potential safety hazard, inefficiency, the technical indicator brought because of oxygen rifle dry slag in the prior art, the utility model provides a kind of converter oxygen gun to prevent the dry slag device.
The utility model is realized by following technical proposal: a kind of converter oxygen gun prevents the dry slag device, it is characterized in that being provided with on oxygen rifle outer tube wall graphite carbon material sheath.
Described graphite carbon material sheath is combined by at least two circular arc sheaths, circular arc jacket inner wall and oxygen rifle outer tube wall by binding agent or/and set screw be connected so that graphite carbon material sheath is installed, is fixed on the oxygen rifle, effectively anti-block rifle dry slag.
Described circular arc sheath is set to two sections at least, have through hole on every section sheath, the inboard of through hole is provided with concave station, and this concave station is matched with the nut that is fixed on the oxygen rifle outer tube wall, so that graphite carbon material sheath is fixed on the oxygen rifle, also be convenient to the local replacing of sheath simultaneously by screw.
Described graphite carbon material sheath is combined by at least two pitch circle tubular sheaths, every pitch circle tubular sheath by binding agent or/and set screw be socketed on the oxygen rifle outer tube wall.
The utlity model has following advantage and effect: adopt such scheme, graphite carbon material sheath promptly is set on oxygen rifle outer tube wall, can make smelting, splash slag and molten steel that the slag splashing operating process produces can directly not stick on the oxygen gun body, thereby reach the purpose of effectively anti-block rifle dry slag, graphite carbon material sheath is made as by polylith in addition, multi-section circular arc shape sheath combines, perhaps be made as by multistage round shape sheath and combine, not only be convenient to install, the local replacing of being more convenient for, can reduce production costs, can enhance productivity again, ensure the raising of production technology and economic target.

Fig. 3 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further, is not limited thereto but hold within the utility model.
Be bonded with graphite carbon material sheath 3 on the oxygen rifle outer tube wall 1,3 by more piece round shape sheath bonding be spirally connected and form, as Fig. 1, sheath 3 also can be combined by two semicircles, as Fig. 3, each semicircle sheath is combined by multistage again, the inwall of every section semicircle sheath is bonded on the oxygen rifle outer tube wall 1 by binding agent 2, on every section semicircle sheath, be provided with through hole 6, the inboard of through hole 6 is provided with concave station 4, and this concave station 4 matches with nut on being welded on oxygen rifle outer tube wall 1, and screw 7 passes through hole 6 and links to each other with nut 5, thereby strengthen the bonding force of graphite carbon material sheath 3 and oxygen rifle outer tube wall 1, as Fig. 2.
