Abstract
The invention provides a device for straightening curved continuous casting billets. The device comprises a frame and a continuous casting billet straightening structure arranged on the frame, wherein the continuous casting billet straightening structure comprises a supporting unit and a jack arranged on the supporting unit, and the supporting unit forms a first-row supporting unit and a second-row supporting unit; the first-row supporting unit and the second-row supporting unit are arranged on the frame side by side, and a space for containing the continuous casting billets is formed between the first-row supporting unit and the second-row supporting unit. By straightening the continuous casting billets being bent and deformed due to non-uniform cooling in the stacking process, the method can effectively make the original bent deformed continuous casting billets flat and straight, and the continuous casting billets enter the next procedure smoothly. Therefore, the percent of pass of casting billets is furthest increased, the rejection rate of casting billets is reduced, and the production cost is reduced. The device has the advantages of being simple in structure, low in manufacture cost and easy to operate and is suitable for popularization and application in the industry.
Description
Technical field
The present invention relates to technical field of steel production, particularly a kind of device of bending continuous casting billet aligning.
Background technology
In continuous small-billet casting production process, continuous casting billet is transported on cold bed after gas flame cuttiug, and after upset, promote it at cold bed exercise by pusher, then handling is stamped on position to the finished product of specifying.And continuous small-billet casting base is when stacking, frequent employing " well word " way of stacking, in handling process, the lower surface last ingot blank contact with it that red heat strand is stacked, upper surface then directly contacts with air, comparatively lower surface is fast to make strand upper surface and two ends cooling velocity, causes strand upper surface temperature low, according to principle of expanding with heat and contracting with cold, upper surface shrinkage ratio lower surface is large, the buckling phenomenon making strand produce two to upwarp, has a strong impact on the quality of continuous casting billet, even cannot enter walking beam furnace.
When especially producing steel alloy, alloy content is high, the buckling phenomenon that two upwarps easily is there is during the cooling of continuous casting billet stacking, continuous casting billet is made to enter walking beam furnace, because alloy steel cost is higher, if bending continuous casting billet cutting is melted down, serious man power and material's waste certainly will be caused, the delivery date of rhythm of production and finished product may be affected simultaneously, therefore, must take effective measures and bending continuous casting billet is aligned, make continuous casting billet keep straight after aligning, after reaching standard, enter next procedure.
Summary of the invention
Technical problem to be solved by this invention is: in order to overcome deficiency of the prior art, the invention provides a kind of device of bending continuous casting billet aligning, by in stacking procedure because the diastrophic continuous casting billet of the even generation of inhomogeneous cooling is aligned, original diastrophic continuous casting billet effectively can be made to change into straight, enter next procedure smoothly.
The present invention solves the technical scheme that its technical problem will adopt: comprise framework and establish continuous casting billet straightened structure on said frame, described continuous casting billet straightened structure comprises support unit and is located at the jack on support unit, described support unit forms first row support unit and second row support unit, described first row support unit and second row support unit are arranged side by side on said frame, and are provided with the space holding continuous casting billet between described first row support unit and second row support unit.When aligning, described continuous casting billet is placed in the space of described accommodation continuous casting billet, is then aligned by described support unit and the described jack pair continuous casting billet be located on described support unit, and this structure is simple, easy to operate.
Further, described first row support unit and/or described second row support unit are provided with described jack, and the piston of described jack can stretch out to the direction in space of described accommodation continuous casting billet.Determine distribution and the position of described jack further, and the one-sided jack that arranges makes operation more simple, and can simplified design structure and saving design cost.
Further, described support unit comprises a side, the described side of described first row support unit is positioned in the first plane, the described side of described second row support unit is positioned in the second plane, described first plane and described second plane are parallel to each other, and described first plane and described second interplanar form the space holding continuous casting billet.The described support unit of further restriction forms two planes be parallel to each other, and straightening work is more easily carried out, and better can ensure the precision of aligning rear continuous casting billet.
