Abstract
The utility model discloses an efficiency of spray repair of RH dip pipe is improved speed reduction shower nozzle, including the shower nozzle body, the upper portion of shower nozzle body is the pipe body, and the lower part of shower nozzle body is opened and is being set up the galvanized iron wire net for the cone pipe body, the bottom surface of the cone pipe body, and galvanized iron wire's diameter is 2.2mm, and the mesh aperture of galvanized iron wire net is 5mm, and the external diameter of the cone pipe body is 40mm, and the length of the pipe body is 50mm, and the length of the internal screw thread of pipe is 20mm. The utility model discloses the preparation is simple and convenient, and is with low costs, and gunning refractory high -usage, the gunning refractory that is come out by the high -velocity jet be through suitably slowing down, glues at the dip pipe inner wall and covers with the sintering effect better, can tear open at any time and trade, and the gunning refractory is piled up to the shower nozzle of avoiding slowing down after the spray repair, and the dismouting is simple and convenient.
Description
Technical field
The utility model relates to a kind of deceleration shower nozzle improving RH soaking tub spray repair efficiency.
Background technology
RH refining is a kind of smelting technology being realized purification of molten steel by vacuum outgas, it is the degassed key link of molten steel that RH vacuum tank vacuumizes, also be key position, because molten steel can burst as a large amount of drops in vacuum tank, so vacuum tank is according to outside box hat, inner structure of being built by laying bricks or stones by resistance to material, the soaking tub of vacuum tank bottom is also all cast by resistance to material and is formed, soaking tub is in use constantly subject to molten steel and corrodes, its thickness starts thinning, in order to its life-span can be extended, the method generally used both at home and abroad adopts gunning technology, the method uses automatization spray repair car by water, pressurized air, Gunning refractory is mixed to form high speed flow and is injected in soaking tub inwall, attack sites can be made up in a short time, the spray repair car of current use is divided into high pressure batch can and tap water, Gunning refractory is squeezed into spray repairing lance for tilting at a high speed by compressor by pressurized air by high pressure batch can, coordinate certain water again, form the wet feed with certain viscosity and speed to be bonded at soaking tub aligning inner and to repair, in order to avoid spray repairing lance for tilting blocking, batch can generally adopts higher output pressure, this does not sinter toward contact the impact being just subject to follow-up Gunning refractory when just causing high pressure wet feed to be sprayed on the soaking tub surface of high temperature, and then drop, each spray repair has the Gunning refractory close to 1/4 to be wasted.
Summary of the invention
The purpose of this utility model is to provide a kind of deceleration shower nozzle improving RH soaking tub spray repair efficiency, can either ensure that spray repairing lance for tilting does not block and can improve the utilization ratio of Gunning refractory.
The purpose of this utility model realizes like this, a kind of deceleration shower nozzle improving RH soaking tub spray repair efficiency, comprise head body, the top of head body is pipe body, and the bottom of head body is circular cone body, the bottom surface of circular cone body is opened wide and is arranged galvanized wire mesh, the diameter of galvanized wire is 2.2mm, and the mesh aperture of galvanized wire mesh is 5mm, and the bottom external diameter of circular cone body is 40mm, the length of pipe body is 50mm, and in pipe body, the length of screw thread is 20mm.
The utility model is a detachable little pore-throat filter screen, both can not affect the speed of material in spray repairing lance for tilting, can reduce its velocity of discharge again, and can not intercept the injection direction of Gunning refractory, can also improve spray repair effect.After using this technology, the average every stove steel of Gunning refractory usage quantity reduces 100kg.The utility model is simple for production, and cost is low, and Gunning refractory utilization ratio is high, slowed down through suitable by high-velocity jet Gunning refractory out, cover with sintering effect better at soaking tub inwall, can change at any time, avoid deceleration shower nozzle to pile up Gunning refractory after spray repair terminates, dismounting is simple and convenient.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is perspective view of the present utility model.
Embodiment
A kind of deceleration shower nozzle improving RH soaking tub spray repair efficiency, as shown in Figure 1, comprise head body, the top of head body is pipe body 2, and the bottom of head body is circular cone body 3, the bottom surface of circular cone body 3 is opened wide and is arranged galvanized wire mesh 4, the diameter of galvanized wire is 2.2mm, and the mesh aperture of galvanized wire mesh is 5mm, and the bottom external diameter of circular cone body 3 is 40mm, the length of pipe body 2 is 50mm, and in pipe body, the length of screw thread 1 is 20mm.
Claims (1)
