Abstract
The invention discloses a technology for correcting steel materials. The technology includes steps that 1), the maximum wave and local unevenness difference of the steel materials cannot exceed certain proportions when inspected by 1mm leveling rulers, and the proportions are not larger than 2 mm when plate thicknesses are smaller than or equal to 14 mm, and are not larger than 1 mm when the plate thicknesses are larger than or equal to 14 mm; 3), the steel materials in cold states are generally corrected by roll type correcting machines or press machines; 4), the steel materials with high bending degrees need to be heated until the temperatures of the steel materials reach 900-1000 DEG C (lower temperatures for low-alloy steel) when the steel materials are about to be corrected in hot states. The technology has the advantages of reasonable working procedures and low manufacturing cost.
Description
Technical field
The present invention relates to a kind of steel rectification technique.
Background technology
Existing steel rectification technique exists that procedure arrangement is unreasonable, operation is various, higher to operator's skill requirement so that production cost is higher.
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 steel rectification technique of low cost of manufacture.
For achieving the above object, the invention provides
A kind of steel rectification technique, comprises the steps:
1), the highest wave of steel and local rough and uneven in surface difference 1mm leveling ruler inspection time, must not exceed following ratio: during thickness of slab≤14mm, no more than 2mm, be not more than 1mm during thickness of slab >=14mm；
2), shaped steel various when deforming more than following table regulation before line, can need to rule after correcting, and local the most wavy in every meter of length less than 2mm；
3), steel rectification is carried out with gaugger or forcing press the most in the cold state；
4), the bigger steel of flexibility hot lower correct time, 900-1000 DEG C (the relatively low temperature of low-alloy steel) should be heated to.
The invention has the beneficial effects as follows: operation of the present invention is reasonable, low cost of manufacture.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
A kind of steel rectification technique, comprises the steps:
1), the highest wave of steel and local rough and uneven in surface difference 1mm leveling ruler inspection time, must not exceed following ratio: during thickness of slab≤14mm, no more than 2mm, be not more than 1mm during thickness of slab >=14mm；
2), shaped steel various when deforming more than following table regulation before line, can need to rule after correcting, and local the most wavy in every meter of length less than 2mm；
3), steel rectification is carried out with gaugger or forcing press the most in the cold state；
4), the bigger steel of flexibility hot lower correct time, 900-1000 DEG C (the relatively low temperature of low-alloy steel) should be heated to.
