Abstract
The present invention relates to a straightening and annealing method for square steel and flat steel. It is characterized by that the square steel or flat steel materials with identical cross-section and specification are superimposed in a clamping apparatus with rectangular cavity, then all the superimposed steel materials are tightly clamped to the required straight line degree, the they are placed into a heat treatment furnace to make annealing. Its heating temp. is 400-700 deg.C and heat-insulating time is 1-15 hr. Said invention can integrate the straightening process and annealing process into one process, so that it can save treatment time, and can reduce production cost.
Description
Technical field
The present invention relates to a kind of treatment process of steel, particularly a kind of side, the alignment of band steel material, annealed method.
Prior art
At present, the alignment of side, band steel material (hot rolling or cold-drawn) and annealing are all carried out separately two operations respectively, promptly carry out at different when and wheres.With regard to the alignment of side, band steel material, all adopt mechanical aligned method at present, as applying pressure machine or running roller straightener; Annealing is carried out in heat treatment furnace usually.Certainly will cause man power and material's bigger consumption and increasing of processing cost like this.
Summary of the invention
Technical problem to be solved by this invention is: a kind of alignment method for annealing of saving square, the band steel material of processing cost and time is provided.
The technical scheme that addresses the above problem is: the alignment method for annealing square, the band steel material that is provided is as follows:
1, at normal temperatures that the cross section is identical with specifications and models square steel or band steel overlay in the anchor clamps with rectangular inner cavity, and are clamped to desired linearity in the total length of square steel or band steel from upper and lower, left and right with the square steel or the band steel of closed assembly,
2, square steel that clamping is good or band steel are put into heat treatment furnace and are annealed, and Heating temperature is 400 ℃～700 ℃, and soaking time is 1～15 hour, and slowly cooling is come out of the stove then.
The present invention unites two into one alignment and annealing, has not only saved the treatment time, has reduced production cost, and improved production efficiency.Because clamped square steel or band steel reached desired linearity, the internal stress of square steel or band steel is again to eliminate in annealing, the back workpiece of coming out of the stove will keep original linearity, so the quality of handling is higher, making square steel or band steel directly be used for doing has the stock class workpiece (as guide rail) of requirement to become possibility to linearity.
Description of drawings
Accompanying drawing is the clamping synoptic diagram of the present invention to square steel or band steel.
Embodiment
As shown in the figure: square steel or band steel 1 are overlayed in the ∏ clevis tool 2, and its both sides are placed with straight clamping plate 3, cover cover plate 4 then, make clamping plate 3 and cover plate 4 push down square steel or band steel by screw 5 again, it is clamped, and reach required linearity, anchor clamps 2 and clamping plate 3 can adopt spheroidal graphite cast iron.The workpiece that clamping is good is put into heat treatment furnace, is incubated 1～15 hour under 400 ℃～700 ℃ temperature, and slowly cooling is come out of the stove then.Concrete Heating temperature and soaking time can be determined according to material, batch and the virgin state of workpiece.
Through test, the present invention is under the prerequisite that guarantees annealing quality, and the short square steel or the linearity of band steel material can reach 0.05 millimeter, and the long square steel or the linearity of band steel material can reach 0.3 millimeter, can satisfy the requirement of some guide rail to linearity fully.
