Abstract
The invention discloses a modifying method for a sectorial water pipe of a continuous casting machine, and belongs to the technical field of continuous casting equipment. The method is mainly suitable for structural design and modification of the sectorial water pipe frame of the continuous casting machine. By changing the position of a water hole, changing a water pipe material and other methods, the problem that the sectorial section is difficult to repair and even is scrapped due to blockage, corrosion, water leakage and the like of a cooling water pipe is solved. The method has the advantages of prolonging the service life of the frame structure of the sectorial section, reducing the influences of water leakage of equipment on the quality of the cast blanks and prolonging the service life of the sectorial section and a roll system.
Description
Technical field
The invention belongs to continuous casting installation for casting technical field.Be particularly related to a kind of continuous casting machine fan-shaped segment water channel remodeling method.
Background technology
Domestic certain 1# of steel mill casting machine fan-shaped section water channel is that grooved carbon steel pipe and framework matrix are welded between frame assembled, when water channel water flowing, sector-segment frames matrix is directly to contact with cooling water, because the time is longer, the corrosion of framework matrix is more serious, directly affects the service life of sector-segment frames.Because tank is first and after framework matrix welding fabrication just to carry out whole assembling, when fan-shaped section off-line maintenance, cannot thoroughly weld mending-leakage and process simultaneously.Because 1# casting machine fan-shaped section is longer service time, at different positions, there is Corrosion blockage in various degree in water channel, although taking repair welding always, but effect is unsatisfactory, and water channel wall thickness is more and more thinner, and water channel internal corrosion thing is more and more, has had a strong impact on the flow of cooling water, causing roller is that bearing cooling effect reduces, the service life of restriction fan-shaped section.Since 2010, the fan-shaped section showed increased that 1# casting machine leaks because of water channel corrosion, because the leak fan-shaped section that rolls off the production line of framework water channel accounts for annual improper 24% of the fan-shaped section total failare that rolls off the production line, rolling off the production line of these fan-shaped section increased rehabilitation cost, make the fluctuation of equipment water rate of water make-up larger, due to the randomness of leaking, exert a certain influence to the quality of strand simultaneously.
The phenomenon that the casting machine fan-shaped section of domestic a lot of steel mills all exists water channel seriously corroded and leaks, and be difficult to normal reparation.Therefore, by fan-shaped section body water channel is carried out to reasonable reformation, reduce component cooling water rate of water make-up, guarantee the relatively stable of component cooling water rate of water make-up, improve the cooling effect of equipment, improve the service life of fan-shaped section and roller system, the minimizing equipment impact on slab quality of leaking to greatest extent, avoid scrapping in advance of sector-segment frames structure simultaneously, increase the service life, reduce the input of turnover spare part.
Summary of the invention
The object of the present invention is to provide a kind of continuous casting machine fan-shaped segment water channel remodeling method.Solution is due to the obstruction of cooling water channel, the problem of corroding and leaking etc. and to cause fan-shaped section reparation difficulty even to be scrapped.
The method is mainly applicable to the Design & reform of continuous casting machine fan-shaped segment water channel frame structure.For solving the problems of the technologies described above, concrete adaptation step is as follows:
1, the inside and outside arc frame of fan-shaped section is disintegrated, remove the parts such as roller group of inside and outside arc frame; Clear up inside and outside arc frame, remove the corrosion of framework matrix surface; Remove water system pipeline, drier oil pipeline and fluid pressure line, clear up and carry out sign, pile up neat;
2, with burning torch, prescind tank and the bearing block pedestal gusset of the inside and outside arc frame of fan-shaped section, and the inside and outside arc frame of fan-shaped section is cleaned out, should be noted and can not hurt matrix;
3, bearing block pedestal and the inside and outside arc frame gripper shoe of fan-shaped section surface finish is smooth, scale removal, corrosion etc., with φ 12 drill bits, in bearing block pedestal two sides, hole, bore position distance axis bearing base-plates surface 35mm, distance axis bearing pedestal keyway center line 75mm, drill through completely with φ 10 limbers in bearing block pedestal, and by the bottom shutoff welding of 10 limbers of the φ in bearing block pedestal, welding and assembling height is 10mm, using bearing block pedestal two sides φ 12 limbers as new inlet opening, and suppress examination water to nothing leakage;
4, with stainless steel square steel, again make water lines, and the welded stub connection of holing, be connected with upper pipe simultaneously, behind location to be welded, install gusset additional and bearing block pedestal welds, and again bearing block pedestal is carried out to centering, according to the position of square steel waterway tube, install hydraulic pressure and lubricated pipeline additional.
In step 4, stainless steel square steel is of a size of 45mm*35mm*4mm and 50mm*32mm*4mm.
After continuous casting machine fan-shaped segment water channel transformation, main channel is walked former route, part arm walk again by; And the framework of part heavy corrosion and distortion and related accessories are transformed to replacing.
Advantage of the present invention:
1, avoid scrapping in advance of sector-segment frames structure, increase the service life, reduce the input of turnover spare part;
2, the impact that minimizing equipment leaks on slab quality to greatest extent;
3, reduce component cooling water rate of water make-up, guarantee the relatively stable of component cooling water rate of water make-up, improve the cooling effect of equipment, improve the service life of fan-shaped section and roller system.
