Description
Technical field
The utility model relates to a kind of device for continuous-cast blank automatic slag removal, belongs to continuous casting production technical field of auxiliary equipment.
Background technology
Continuous casting cutting is the important ring in continuous casting production process, significant impact is had to slab quality and billet yield, the gas flame cuttiug mode generally adopted both at home and abroad at present, when cutting thickness is less than the strand of 150mm, effect is ideal, but when cutting thickness is greater than 150mm or some special steel, then ubiquity strand dross phenomenon, because in the gas flame cuttiug process of strand, the steel of cutting part melt as liquid molten steel, liquid molten steel prolongs strand cutting section and flows downward, progressively condensation accumulation below strand cutting section, formation is similar to dross phenomenon like north of china in winter eaves silver thaw, outside the impact of removing steel grade, ordinary circumstance is that slab thickness is larger, dross is more serious.
In order to not affect follow-up steel rolling process after strand dross, not only need to spend a large amount of manpower and materials to remove, and because need to repair casting billet surface in reset procedure, affect strand cut lengths, and cause excessively pruning to cause steel to be wasted.For the problems referred to above, many trials have been done, as adopted mechanical scarfing cinder by domestic steel enterprise, or improve cutting flame temperature to prevent the liquid molten steel premature set etc. in cutting process as far as possible, but or effect is undesirable, or apparatus expensive is safeguarded complicated, all there is such-and-such problem in use procedure.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of device that automatically can carry out strand scarfing cinder in real time, automatically can complete the cleaning of strand cutting dross in good time, solve background technology defect under the prerequisite of not carrying out scrap build.
The technical scheme solved the problems of the technologies described above is:
A kind of continuous-cast blank automatic dreg removing device, formation comprises steam line, pipe clamp, fixed base plate and scarfing cinder shower nozzle, and steam line is through interconnective pipe clamp and fixed base plate, and steam line end connects the scarfing cinder shower nozzle be parallel to each other with horizontal plane.
Above-mentioned continuous-cast blank automatic dreg removing device, described pipe clamp is bolted by width, the rectangular slab highly matched and L-type plate and forms, the opposite face of rectangular slab and L-type plate is provided with semicircle draw-in groove, draw-in groove diameter and steam line diameter match, and the parallel connection of bolt is passed through with fixed base plate in the bottom surface of L-type plate.
Above-mentioned continuous-cast blank automatic dreg removing device, described fixed base plate is rectangle, and width is identical with pipe clamp width, and U-type groove is offered at center along its length, and U-type groove width and steam line diameter match.
Above-mentioned continuous-cast blank automatic dreg removing device, described steam line is made of metal, and the spout of described scarfing cinder shower nozzle is rectangular.
The beneficial effects of the utility model are:
When the utility model uses, fixed base plate is connected with strand cutting equipment, steam line access source of the gas, make the jet direction of scarfing cinder shower nozzle identical with strand cut direction, the Automatic clearance of strand dross can be realized, the gas sprayed by scarfing cinder shower nozzle, fan-shaped sheet air curtain can be formed before shower nozzle, the liquid molten steel formed in strand cutting process is blown out in time, effective removing strand dross, according to distinct device situation and bleed pressure, by the adjustment up and down regulating the bolt of pipe clamp and fixed base plate to realize steam line and scarfing cinder shower nozzle, enhance the flexible applicability of equipment.The utility model manufacture difficulty is little, and expense is low, and can use as the plug-in parts of flame cutting equipment when not changing existing equipment, therefore applied widely, all types of continuous casting flame cutting equipment all can support the use.

In figure, mark is as follows: steam line 1, pipe clamp 2, fixed base plate 3, scarfing cinder shower nozzle 4, rectangular slab 5, L-type plate 6.
Detailed description of the invention
As shown in the figure, the utility model comprises metal steam line 1, pipe clamp 2, fixed base plate 3 and scarfing cinder shower nozzle 4.Pipe clamp 2 is bolted by two pieces of width and the identical rectangular slab of height dimension and L-type plate and forms, the opposite face of rectangular slab and L-type plate offers the semicircle draw-in groove matched with steam line 1 diameter, the width of fixed base plate 3 is identical with the width of pipe clamp 2, the U-type groove that width and steam line 1 diameter match is offered at the center of length direction, the parallel connection of bolt is passed through with fixed base plate 3 in the bottom surface of the L-type plate of pipe clamp 2, steam line 1 passes perpendicularly through pipe clamp 2 and fixed base plate 3, scarfing cinder shower nozzle 4 is connected with steam line 1 end and scarfing cinder shower nozzle 4 is arranged in parallel with horizontal plane, jet direction is identical with strand cut direction, the rectangular spout of spout.
The course of work of the present utility model is as follows:
Source of the gas is by telescopic flexible pipe access steam line 1, fixed base plate 3 is fixedly connected with cutting equipment, scarfing cinder shower nozzle 4 is made to be positioned at correct position below strand by regulating the bolt on fixed base plate 3 and pipe clamp 2, steam line 1 is positioned at strand side correct position, the jet direction of scarfing cinder shower nozzle 4 is identical with cut direction, in cutting process, cutting equipment moves with strand, Telescopic flexible pipe shrinks with the movement of cutting car or stretches, ensure uninterrupted air feed, air-flow arrives scarfing cinder shower nozzle 4 position by steam line 1, by the rectangle spray orifice ejection on scarfing cinder shower nozzle 4, fan-shaped sheet air curtain is formed under strand cutting section, the liquid molten steel produced in cutting process and dross flow from top to bottom on cutting casting blank section, arrive under cutting section along time, have little time to solidify, namely removing is blown away by air curtain.
In scarfing cinder process, as undesirable in found scarfing cinder effect, the bolt on pipe clamp 2 and fixed base plate 3 can be unclamped, the position of upper and lower front and back adjustment steam line 1, because scarfing cinder shower nozzle 4 is fixed on steam line 1, therefore scarfing cinder shower nozzle 4 also shift position thereupon, to be adjusted after ideal position, fastening bolt, makes slag cleaning device fix, and continues scarfing cinder.
