Description

Continuous casting blank scale eliminating device
Technical field
The utility model relates to a kind of continuous casting blank scale eliminating device.
Background technology
When producing rolled steel by the hot rolling method, oxide skin, metal derby, burr or the foreign matter on continuous casting billet surface is pressed into that rolled piece is inner can form defective, causes the waste of material and the energy.Therefore all to carry out necessary de-scaling work before hot rolling.Along with improving constantly of stocking surface quality, iron and steel enterprise has higher requirement to scale removal effect.
Mainly adopt at present the mode of high-pressure water descaling, the high-pressure water descaling water requirement is large, and the water that flows through casting billet surface is taken away amount of heat, causes the temperature drop that strand is larger, is unfavorable for follow-up hot-rolled process, and the waste resource.
In addition, the active force of compressed gas descaling is less, is difficult to reach very high scale removal effect.Mechanical descaling method needs very high equipment precision and control accuracy, and careless manipulation easily causes the defectives such as scuffing to casting billet surface, and part de-scaling parts are worn, and belongs to running stores, increases cost.
Need a kind of economic, convenient and effective de-scaling equipment for this reason.
The utility model content
In order to solve the aforementioned problems in the prior, the utility model provides a kind of continuous casting blank scale eliminating device, described continuous casting blank scale eliminating device comprises: water tank, by filtering baffle plate, water tank is divided into upper-side area and underside area, wherein, upper-side area accommodates hard particles and water, and underside area accommodates water; The de-scaling workspace is ejected into the hard particles in described upper-side area and water on continuous casting billet in the de-scaling workspace, with to the continuous casting billet de-scaling; Clean work area after being positioned at the de-scaling workspace, being ejected into the water in described underside area on continuous casting billet in clean work area and cleaning.
According to exemplary embodiment of the present utility model, in the de-scaling workspace, hard particles and water are injected on continuous casting billet by nozzle, and described nozzle becomes the angle of 15 ° to 35 ° with continuous casting billet.Be provided with agitating device in the upper-side area of water tank, so that hard particles and water are stirred into uniform line.
According to exemplary embodiment of the present utility model, described hard particles has round and smooth surface.
Can improve scale removal effect according to continuous casting billet treating apparatus of the present utility model, and technique is simple, need not other optional equipment.
Description of drawings
By the reference accompanying drawing, the utility model is described in detail, it is clearer that feature and advantage of the present utility model will become, in the accompanying drawings:
Fig. 1 is the schematic diagram according to continuous casting blank scale eliminating device of the present utility model.
The specific embodiment
Hereinafter, describe with reference to the accompanying drawings exemplary embodiment of the present utility model in detail.
Fig. 1 is the schematic diagram according to continuous casting blank scale eliminating device of the present utility model.With reference to Fig. 1 as can be known, comprise according to continuous casting blank scale eliminating device of the present utility model: water tank 2, by baffle plate 3, water tank 2 is divided into two parts, that is, and upper-side area and underside area; De-scaling workspace 11; Clean work area 12, the continuous casting billet 1 of process de-scaling workspace 11 de-scalings enters clean work area 12.
Specifically, according to exemplary embodiment of the present utility model, baffle plate 3 can be for filtering baffle plate, and baffle plate 3 will filter from the recirculated water that the top of water tank 2 is injected, prevent that the hard particles 4 such as fine sand, shot from entering in the underside area of water tank 2, water can enter in the underside area of water tank 2.In addition, be provided with agitating device 6 in the upper-side area of water tank 2, thereby the hard particles 4 such as water in water tank 2 upper-side area and fine sand, shot are stirred, form line comparatively uniformly.
The line of the mixture of the hard particles 4 such as the water in the upper-side area of water tank 2 and fine sand, shot is after the processing of piping 7 and conveying and pressue device 8, the nozzle 9 of arrival de-scaling workspace 11, and be ejected into the surface of continuous casting billet 1 with certain angle, thereby carry out de-scaling.
Water in the underside area of water tank 2 is after the processing of piping and conveying and pressue device, arrive the nozzle of clean work area 12, and be ejected into the continuous casting billet 1 of having processed through de-scaling, thereby cleaning may remain in lip-deep iron scale or the solid particle of continuous casting billet 1.
According to exemplary embodiment of the present utility model, adopt the descaling method of above-mentioned continuous casting blank scale eliminating device as follows: with continuous casting billet 1 through heating furnace 10 heat treated after, be transported to de-scaling workspace 11 by roller-way 13; In the de-scaling process, adopt agitating device 6 that the hard particles 4 in the upper-side area of water tank 2 is stirred with water 5 and form uniform line; The mixture of hard particles 4 and water 5 is delivered to the nozzle 9 of de-scaling workspace 11 through piping 7 with after carrying pressue device 8 to process; The mixture of hard particles 4 and water 5 is carried out de-scaling with pressure injection to the surface of continuous casting billet 1 at a certain angle; Continuous casting billet 11 through de-scaling enters clean work area 12, water 5 in the underside area of water tank 2 is delivered to the nozzle 9 of cleaning area 12 after piping 7 and conveying and pressue device 8 processing, and be ejected on continuous casting billet 11, thereby iron scale or solid particle that cleaning may be residual; Continuous casting billet through de-scaling and cleaning is delivered to milling train 14 through roller-way 13.
In addition, according to exemplary embodiment of the present utility model, the hard particles such as fine sand, shot 4 have rounder and more smooth surface, without sharp-pointed corner angle, thereby prevent from the surface of conveyance conduit and continuous casting billet is produced hard defects.
According to exemplary embodiment of the present utility model, be adapted to have the continuous casting billet de-scaling of the iron scale of different-thickness by regulating hydraulic pressure.In addition, the size and number of hard particles and the power of agitating device, hydraulic pressure etc. all can affect scale removal effect, and preferably, hard particles and water form uniform high pressure line.
