Abstract
The utility model belongs to the improvement, especially a spray repair rifle of dip pipe is repaired to modified of the RH spray repair rifle structure of repair dip pipe, spray repair rifle including repairing the dip pipe passes through threaded connection in the exit of spray repair rifle and fan nozzle, is the length of fan nozzle's flat spout 8 10cm, is the width 5 6cm, the fan nozzle of spray repair rifle is corresponding with the inner wall of dip pipe. The utility model discloses rational in infrastructure, the preparation is convenient, the gunning refractory use amount that can significantly reduce, 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 cover with the sintering effectually, improves the spray repair effect.
Description
Technical field
This utility model belongs to the improvement of the RH spray repairing lance for tilting structure repairing dip pipe, the spray repairing lance for tilting repairing dip pipe of a kind of improvement.
Background technology
nullRH refine is a kind of smelting process being realized purification of molten steel by vacuum outgas，RH vacuum tank evacuation is the key link of molten steel degassing，Also it is key position，Owing to molten steel can burst as substantial amounts of drop in vacuum tank，So vacuum tank is according to outside box hat，The internal structure built by laying bricks or stones by resistance to material，The dip pipe of vacuum tank bottom is the most all formed by the casting of resistance to material,Dip pipe is in use constantly corroded by molten steel，Its thickness starts thinning，In order to extend its life-span，The method commonly used both at home and abroad is to use gunning technology，The method is to use automatization's spray repair car by water、Compressed air、Gunning refractory is mixed to form high velocity stream and is injected in dip pipe inwall，Attack sites can be made up in a short time，Currently used spray repair mode is that gunning refractory is squeezed into spray repairing lance for tilting at a high speed by compressor by compressed air by high pressure batch can，Coordinate certain water again，Formed and have that the wet feed of certain viscosity and speed is viscous to be repaired to dip pipe inwall from circular lance ejection，In order to avoid spray repairing lance for tilting blocks，Batch can typically uses higher output pressure，This results in not sinter toward contact when high pressure wet feed is sprayed on the dip pipe surface of high temperature and is just impacted by follow-up gunning refractory，And then drop，Spray repair has the gunning refractory close to 1/4 to be wasted every time，Therefore how ensureing that spray repairing lance for tilting does not blocks and can improve the utilization rate of gunning refractory is the problem that solution is presently required.
Utility model content
The purpose of this utility model is to provide the spray repairing lance for tilting repairing dip pipe of a kind of improvement, it is rational in infrastructure, easy to make, gunning refractory usage amount can be greatly reduced, gunning refractory utilization rate is high, by high velocity jet gunning refractory out through suitably slowing down, it is good with sintering effect to cover at dip pipe inwall, improves spray repair effect.
The purpose of this utility model is achieved in that the spray repairing lance for tilting repairing dip pipe of a kind of improvement, including the spray repairing lance for tilting repairing dip pipe, it is threaded connection fan nozzle in the exit of spray repairing lance for tilting, the a length of 8-10cm of the flat spout of fan nozzle, width is 5-6cm, and the fan nozzle of spray repairing lance for tilting is corresponding with the inwall of dip pipe.
It is as follows that this utility model mainly improves content:
First, the internal diameter of original spray repairing lance for tilting exit site 20mm length is carried out hot candied formation internal thread, then the steel pipe 50mm length of small diameter is used, one end is pulled out the outer silk of 20mm length be allowed to mate with the screw thread at spray gun position, then the other end of without screw thread is baked red after impact with iron hammer, it is changed into the plain jet of bending, by nozzle screw thread and spray repairing lance for tilting screwed connection during use, the advantage of secondary nozzle is: 1, round nozzle impetus is concentrated mainly on center, gunning refractory is washed away seriously, impetus is disperseed on line by plain jet, scouring capability dies down, 2, self there is ray during the ejection of exit site gunning refractory to intersect, again gunning refractory jet velocity is weakened further, 3, spray repair operation of the same area, line style spray repair is more in hgher efficiency than point-type spray repair.
This utility model is rational in infrastructure, easy to make, it is achieved that greatly reduce gunning refractory usage amount, and gunning refractory utilization rate is high, and by high velocity jet gunning refractory out through suitably slowing down, it is good with sintering effect to cover at dip pipe inwall, improves spray repair effect.
Accompanying drawing explanation
Being further described this utility model below in conjunction with accompanying drawing, Fig. 1 is main TV structure schematic diagram of the present utility model, and Fig. 2 is the main TV structure schematic diagram of fan nozzle, and Fig. 3 is the plan structure schematic diagram of fan nozzle.
Detailed description of the invention
A kind of repair dip pipe the spray repairing lance for tilting of improvement, as shown in Figure 1, Figure 2, Figure 3 shows, including the spray repairing lance for tilting 2 repairing dip pipe 1, it is threaded connection fan nozzle 3 in the exit of spray repairing lance for tilting 2, the a length of 8-10cm of the flat spout of fan nozzle 3, width is 5-6cm, and the fan nozzle 3 of spray repairing lance for tilting 2 is corresponding with the inwall of dip pipe 1.Arranging screw thread 4 on the inlet tube of fan nozzle 3, be connected to side bending and acclivitous fan nozzle 3 on inlet tube, the angle of inclination of fan nozzle 3 and horizontal angle are 25 °-30 °.
Claims (2)
1. the spray repairing lance for tilting repairing dip pipe improved, including the spray repairing lance for tilting (2) repairing dip pipe (1), it is characterized in that: be threaded connection fan nozzle (3) in the exit of spray repairing lance for tilting (2), the a length of 8-10cm of the flat spout of fan nozzle (3), width is 5-6cm, and the fan nozzle (3) of spray repairing lance for tilting (2) is corresponding with the inwall of dip pipe (1).
The spray repairing lance for tilting repairing dip pipe of improvement the most according to claim 1, it is characterized in that: screw thread (4) is set on the inlet tube of fan nozzle (3), being connected on inlet tube to side bending and acclivitous fan nozzle (3), the angle of inclination of fan nozzle (3) and horizontal angle are 25 °-30 °.
