Abstract
The invention relates to a soft tin plate and a production method thereof. The soft tin plate is characterized in that the soft tin plate comprises the following components in percentage by weight as follows: 0.018-0.030% of C, 0.02-0.05% of Si, 0.06-0.25% of Mn, 0.005-0.02% of P, 0.005-0.015% of S, 0.02-0.06% of Alt, 0.05-0.08% of Cr, 0.02-0.05% of V, 0.002-0.004% of N and the balance of Fe and inevitable impurities. Compared with the prior art, the technical scheme is relatively simple and easy to operate, and the soft thin plate produced is good in performance and good in anti-aging performance, and meets the demand of production.
Description
Technical field
The present invention relates to a kind of tin plate and manufacture method thereof, particularly relate to requirement have necessarily resisted stupefied performance soft tin-plate and manufacture method thereof, belong to the metallic substance technical field.
Background technology
Gaily decorated basket bucket is the more special container of a kind of shape, is widely used in flowing materials such as chemical industry splendid attire paint, coating.Usually, before tin plate is processed into gaily decorated basket bucket, need be coated with, processing such as printing, steel plate needs repeatedly to toast through the temperature more than 200 ℃ when wherein being coated with, at this moment, if there is more solid solution atom in the steel plate, steel plate can produce timeliness because of the effect of solid solution atom, in follow-up steel plate is carried out the hole enlargement distortion, can cause outward appearance to play stupefied phenomenon, even also can reduce cracking such as the operation that causes enlarging, crimping because of unit elongation because the stretching slippage produces slip line.
Documents and materials introduction in the prior art can be produced in the method for the material that satisfies the service requirements of gaily decorated basket bucket.Wherein the most representative is utilization ultra low-carbon steel technology, fixes carbon, nitrogen compound in the steel by adding Ti or Nb.Though the ultra low carbon steel slab aging performance is fine, but ultra low-carbon steel requires steel making working procedure control C content below 50PPM, compare with carbon aluminium-killed steel, the process window of its manufacturing cost and each operation all is in a disadvantageous position, problems such as process control that brings as the carburetting of casting cycle, higher hot rolling finishing temperature and surface, and the welding property of ultra low carbon steel slab the problem of weld cracking occurs often also not as good as carbon aluminium-killed steel in the production of gaily decorated basket bucket.Therefore, a kind of new method of exigence solves above-mentioned technical problem.
Summary of the invention
The present invention proposes strong soft tin-plate of a kind of manufacturability and manufacture method thereof just at the technical problem that exists in the prior art.In order to reach above purpose, technical scheme of the present invention is as follows: a kind of soft tin-plate, and the mass percent of this tin plate composition is as follows: C:0.018-0.030%, Si:0.02-0.05%, Mn:0.06-0.25%, P:0.005-0.02%, S:0.005-0.015%, Alt:0.02-0.06%; Cr:0.05-0.08%, V:0.02-0.05%, N:0.002-0.004%, surplus is that Fe and other unavoidable impurities constitute.In the composition design, under the prerequisite of the C that selects reasonably, manufacturability is strong, N constituent content, add a certain amount of Al,, add a certain amount of Cr and V,, reduce C, the solid solution capacity of N atom in tin plate with this in order to form carbide in order to form nitride.
As a kind of improvement of the present invention, the mass percent of described tin plate composition is as follows: C:0.020-0.025%, Si:0.03-0.04%, Mn:0.015-0.20%, P:0.008-0.01%, S:0.008-0.010%, Alt:0.03-0.05%; Cr:0.06-0.08%, V:0.03-0.04%, N:0.003-0.004%, surplus is that Fe and other unavoidable impurities constitute.
A kind of soft tin-plate production method is characterized in that, said method comprising the steps of: 1) mentioned component is mixed, heat or remain on temperature more than 1150 ℃, in the time of 800-1000 ℃, finish finish to gauge, in the time of 650-850 ℃, finish and batch; 2) the hot rolling draft with 70-90% after overpickling that obtains is carried out cold rolling process production; 3) carry out recrystallization annealing with 700-735 ℃ temperature, use the mode of inclination timeliness, annealing time is 50s-80s; 4) use smooth technology, steel plate is carried out the smooth of unit elongation 1-2%.After the hot rolling finish to gauge, adopt 650-850 ℃ high temperature coiling technique, to promote separating out of carbon, nitrogen compound.The effect of recrystallization annealing temperature is to promote fully separating out of carbide and nitride, reduces the content of solid solution carbon, nitrogen in the steel plate.Use smooth technology, to improve the ageing resistance energy of tin plate.
With respect to prior art, this technical scheme is fairly simple, operation easily, and the soft tin-plate performance of producing is good, and anti-timeliness is good, satisfies the requirement of producing.
