Abstract
The invention discloses a correction process of H-type steel. The correction process of the H-type steel comprises the following steps that (1) angle deformation of a H-type steel wing plate is corrected; (1.1) the number of correction times varies according to the different thicknesses and deformation sizes of the wing plate; usually, when the thickness t of the wing plate is smaller than or equal to 10 mm, correction is completed once, and when the thickness t of the wing plate is larger than 10 mm, correction is realized twice, three times or more according to conditions; (1.2) during conduction of leveling, the height and tightness of a left correction roller and a right correction roller are determined through trial leveling and trial measurement, and the leveling condition is checked through a square; (1.3) according to the requirements of a corrected component, the wing plate is flat, and the two sides are perpendicular to a web; (1.4) when correction of one surface is qualified, the wing plate is overturned through 180 degrees and the other surface of the wing plate is corrected according to the mode until correction of the other surface is qualified; and (2) correction of wavy deformation of the H-type steel web is carried out. The correction process of the H-type steel is reasonable in procedure and low in manufacturing cost, all parameters are collocated reasonably and coordinately, and the product quality and production efficiency can be effectively improved.
Description
Technical field
The present invention relates to the correction process of a kind of H profile steel.
Background technology
The correction process of existing H profile steel exists that procedure arrangement is unreasonable, operation is various, and technological parameter selects unreasonable, and the collocation of each technological parameter is unreasonable and operator's skill requirement is higher so that production cost is higher, product quality is on the low side, yield rate is not high.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved be to provide a kind of operation rationally, the correction process of the H profile steel of low cost of manufacture.
For achieving the above object, the invention provides
The correction process of a kind of H profile steel, is characterized in that: comprise the steps:
1), the correction of H profile steel wing plate angular deformation
1.1) correction of H profile steel wing plate angular deformation, different according to wing plate thickness, deformation varies in size, the number of times of correction is also different, and during general wing plate thickness t≤10, only correction once can complete, during thickness of slab t > 10, according to circumstances, can even repeatedly be realized correction by 2～3 times；
1.2) when implementing smoothing, can first carry out examination school, try to measure and determine the left and right height of two corrector roll positions, degree of tightness, and carry out the flat situation of self calibration with square；
1.3) component corrected requires as wing plate smooth, and both sides are all vertical with web；
1.4) when one side correct qualified after, then overturn 180 °, ibid method correction another side wing plate is until qualified；
2), the correction of H profile steel web wave transformation
2.1) correction of H profile steel web wave transformation is also undertaken by the method for flame correction；
2.2) if web has more wave transformation, then at the high spot of the width of web, wire heating can be carried out along width, and adopt the method crowded around to high spot, and during as smoothed for the first time, then can in first time heated perimeter, again heat, then smooth；
2.3) if web only locally has wave transformation, Flos Mume point-like heating can be adopted to correct, heating location is positioned at crowning, the desirable 20mm of round dot diameter of heating, is spaced apart 50～10mm and is uniformly distributed, heating-up temperature is 700 DEG C～900 DEG C, when being heated to determined temperature, beat this place and peripheral region, Chui Dashi immediately with wooden mallet, back side application wooden mallet pad is lived, steady to keep tie.
The invention has the beneficial effects as follows: operation of the present invention is reasonable, low cost of manufacture, each parameter collocation reasonable coordination, it is possible to be effectively improved product quality and production efficiency.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
The correction process of a kind of H profile steel, comprises the steps:
1), the correction of H profile steel wing plate angular deformation
1.1) correction of H profile steel wing plate angular deformation, different according to wing plate thickness, deformation varies in size, the number of times of correction is also different, and during general wing plate thickness t≤10, only correction once can complete, during thickness of slab t > 10, according to circumstances, can even repeatedly be realized correction by 2～3 times；
1.2) when implementing smoothing, can first carry out examination school, try to measure and determine the left and right height of two corrector roll positions, degree of tightness, and carry out the flat situation of self calibration with square；
1.3) component corrected requires as wing plate smooth, and both sides are all vertical with web；
1.4) when one side correct qualified after, then overturn 180 °, ibid method correction another side wing plate is until qualified；
2), the correction of H profile steel web wave transformation
2.1) method of the correction of H profile steel web wave transformation also using flame correction carries out；
2.2) if web has more wave transformation, then at the high spot of the width of web, wire heating can be carried out along width, and adopt the method crowded around to high spot, and during as smoothed for the first time, then can in first time heated perimeter, again heat, then smooth；
2.3) if web only locally has wave transformation, Flos Mume point-like heating can be adopted to correct, heating location is positioned at crowning, the desirable 20mm of round dot diameter of heating, is spaced apart 50～10mm and is uniformly distributed, heating-up temperature is 700 DEG C～900 DEG C, when being heated to determined temperature, beat this place and peripheral region, Chui Dashi immediately with wooden mallet, back side application wooden mallet pad is lived, steady to keep tie.
