The descaling box and the upper header thereof in the utility model is advantageous in that: automatic and accurate adjustment of the height of the upper header of the descaling box can be performed according to thicknesses of different slabs, thereby guaranteeing blank materials with different thicknesses to reach an optimal descaling effect.
Description
Technical field
The utility model relates to a kind of metallurgical machinery equipment, and more particularly, the utility model relates to a kind of processing mechanical apparatus of metallurgical slab.
Background technology
In metallurgical hot rolled steel plate processing, thick de-scaling is one vital operation, and de-scaling all is by last lower collector pipe of establishing in the De-scaling box and descaling jet practical implementation thereof usually; The quality of thick scale removal effect directly has influence on the quality of subsequent product surface quality and even total quality and the market position and the economic benefit of enterprise.
For better satisfying market demand, nearly all hot rolled steel plate enterprise all can use the blank of several kinds of different section thickness to organize production, does not wait from 150mm to 270mm like the thickness of certain medium plate mill's various blanks.Because the slab lower surface is carried the fixedly height such as grade above the roller-way of slab all the time with in the De-scaling box; Therefore the distance between de-scaling lower collector pipe and nozzle and slab lower surface can remain unchanged; But; The change that the slab upper level can often vary in size along with the slab thickness difference, correspondingly, the change that the spacing of De-scaling box upper header and nozzle and slab upper surface also can often vary in size.
Usually, descaling jet and steel slab surface distance can not be excessive, otherwise water spray pressure reduces, and influences scale removal effect; Nozzle and steel slab surface distance can not be too small, otherwise the water spray coverage rate is incomplete, influences scale removal effect yet.In order to obtain best scale removal effect, smelter can be fixed the installing and locating size of the upper and lower collector of De-scaling box after confirming through detailed design, check, to scheme to keep the optimum distance of descaling jet and steel slab surface.
Yet; For slab thickness frequent change bring the regular change of spacing of de-scaling upper header nozzle and slab upper surface and thus due to the reduction of scale removal effect; Conventional art does not give abundant attention fully; Some traditional technique of scale removal is also only adjusted from the nozzle angle aspect, causes scale removal effect fluctuation deterioration problem long-term existence or hesitates to move forward greatly because of the technological transformation difficulty.
Summary of the invention
Above-mentioned shortcoming to prior art; The purpose of the utility model is that a kind of De-scaling box and upper header thereof will be provided; It has following advantage: can carry out automatically and accurate the adjusting De-scaling box upper header height according to different slab thicknesses, thereby guarantee can both reach best scale removal effect to the different-thickness blank.
For this reason; One of technical solution of the utility model is a kind of De-scaling box upper header; Said De-scaling box comprises frame, carry the roller-way of slab, be located at the roller-way top upper header, be located at the lower collector pipe of roller-way below; And said upper header liftably is assemblied on the said frame through Motorized lift device, and this Motorized lift device also connects and be controlled by control circuit.
Ignore the slab thickness change to the seriousness of the spacing influence of change of de-scaling upper header nozzle and slab upper surface and the mistaken ideas of traditional technological transformation direction to conventional art; The inventor analyzes discovery with caning see what others cannot: many de-scaling inefficiency; All be because seem due to the spacing of inappreciable de-scaling upper header nozzle and slab upper surface changes to a great extent; For this reason; The utility model has been installed Motorized lift device and control circuit thereof between De-scaling box upper header and frame; Thereby make upper header and nozzle height thereof can fully adapt to the variation of slab thickness neatly, guarantee that upper header and nozzle and slab upper surface are in optimal spacing all the time, give full play to the de-scaling ability of upper header high-pressure washing water.Facts have proved that the automatic arrangement for adjusting height of this upper header can solve the problem of the scale removal effect fluctuation decline of De-scaling box at one stroke, effectively ensures the best scale removal effect of De-scaling box to the different-thickness blank.
According to measured data; It is 150mm that traditional upper header of not adjusting height can only satisfy jetting height to thickness 250mm blank usually, like this, and when being the de-scaling of thickness 200mm blank; The injection hitting power just has only 0.5625 times of 250mm blank; And when being the de-scaling of 150mm blank for thickness, the injection hitting power just has only 0.36 times of 250mm, and scale removal effect significantly reduces.And the utility model upper header is regulated jetting height automatically according to sotck thinkness, thereby guarantees that it is 100% that hitting power is sprayed in the de-scaling of the cut deal blank of any thickness.
Be further frame for movement and the water oil power syndeton of optimizing the automatic arrangement for adjusting height of upper header; Improve the up-down control efficiency; Prevent that upper header from producing displacement in the horizontal direction, guarantee to go up and down steadily reliable and scale removal effect, the utility model comprises that following concrete structure improves:
