Abstract
The present invention relates to a kind of method and cold-rolled steel sheet for designing thin-walled sauce bucket cold-rolled steel sheet.The present invention, for design method, high-intensity band steel intensity etc. is carried out to typical sauce bucket for designing, staving is typically at simple stress state, therefore the wall thickness of staving can be with modus ponens using intensity etc.
Description
Technical field
The present invention relates to a kind of system of selection of thin-walled sauce bucket cold-rolled steel sheet and cold-rolled steel sheet.
Background technology
In recent years, going deep into China's open policy, more commodity are sold abroad, and are used as the steel drum of packing material
Gone abroad also with commodity, more effectively realize the value of itself.However, for the packaging of export goods, we are usually
And without the concern for reuse the problem of, the thought disposably put into is gradually received by people.So occurring in the world
Slim steel drum and ultrathin steel drum, as long as cargo security can be inerrably sent to destination, also just complete the packaging of steel drum
Mission, the need for this is value engineering economy.In China, except a small number of pail packs such as outlet calcium carbide barrel are using 0.8 milli
Outside the steel plate of rice, other steel drums are also not carried out slimming.At present in 200 liters of taper sauce bucket productions of outlet, 0.7mm-
0.8mm steel plate has started to be applied, and has saved packing cost.Raw material have not only been saved in the slimming of steel drum, are reduced
Cost, and weight also greatly reduces.
The method and cold-rolled steel sheet of existing design sauce bucket cold-rolled steel sheet, during the production practices of 0.7mm sauce bucket
It has been found that having intensity not enough and situation about being deformed after sauce bucket pressure-bearing occur, below 0.7mm thin-walleds sauce bucket can not be met naturally
Intensity and security needs.In addition raw material have not only been saved in the slimming of sauce bucket, also greatly reduce the weight of packaging.
From above-mentioned, the need for meeting sauce bucket thinning tendency, the method for existing design sauce bucket cold-rolled steel sheet
And there is the not enough limitation of intensity in cold-rolled steel sheet, it is therefore desirable to which a kind of new technology makes up the deficiencies in the prior art.
The content of the invention
The present invention proposes the system of selection of thin-walled sauce bucket cold-rolled steel sheet a kind of and cold in view of the problem of prior art is present
Rolled steel plate, can be in the case where the thickness of sauce bucket be thinned to 0.6mm, and intensity is better than what is produced using original technology with security
Sauce bucket, it is to avoid the problem of existing sauce wood material intensity is not enough.
The present invention provides a kind of system of selection of thin-walled sauce bucket cold-rolled steel sheet, on the premise of original structure is constant, carries out
The generation design such as intensity, in the case where intensity is not less than original structure, if the wall thickness and yield stress of pure sauce bucket cold-rolled steel sheet point
Not Wei t0 and (σ s) 0, be now ready for being replaced using a kind of high strength cold rolled steel plate, the corresponding wall thickness of high strength cold rolled steel plate
Yield stress with material is respectively t1 and (σ s) 1, and the wall thickness t1 of new sauce bucket is：
（1）
Utilize formula（1）The intensity of obtained high strength component is calculated, former general steel plate component, the intensity of total is not less than
Also it is not less than original structure.
Find out from the equations above what high strength steel plate material former general steel plate is replaced with, directly with original structure component
Wall thickness and material yield stress be associated.In actual use, only it is to be understood that the yield limit of new material.So
Obtained structure is content to retain sovereignty over a part of the country complete.
The present invention also provides a kind of thin-walled sauce bucket cold-rolled steel sheet, and its chemical component weight percentage is：C：0.12-
0.17%, Si:0.05-0.2%, Mn：0.6-1.2%, P：≤ 0.025%, S：≤ 0.006%, N：≤ 0.006%, Al：0.02-
0.07%, B：0.0005-0.0012%, remaining is Fe and inevitable impurity.
From the technical scheme of the invention described above, the present invention can solve the problem that the material caused by the thickness of sauce bucket is thinned
Expect the problem of intensity is not enough, sauce bucket is effectively ensured uses safety.The present invention can reduce the thickness of sauce bucket, so as to reduce single barrel
Weight, had not only reduced material cost but also the reduction transportation energy resource consumption of sauce bucket.
Embodiment
A kind of system of selection of thin-walled sauce bucket cold-rolled steel sheet, on the premise of original structure is constant, carries out the generation design such as intensity,
In the case that intensity is not less than original structure, if pure sauce bucket is respectively t0 and (σ s) 0 with the wall thickness and yield stress of cold-rolled steel sheet,
It is now ready for being replaced using a kind of high strength cold rolled steel plate, the yield stress of the corresponding wall thickness of high strength cold rolled steel plate and material
Respectively t1 and (σ s) 1, the wall thickness t1 of new sauce bucket are：
（1）
Utilize formula（1）The intensity of obtained high strength component is calculated, former general steel plate component, the intensity of total is not less than
Also it is not less than original structure.
For example：Former common cold-rolled steel sheet is replaced using 0.6mm high strength cold rolled steel plates material, t0=0.7mm, (σ s) 0=
195MPa；t1=0.6mm；
Therefore： (σs)1=to/t1*(σs)0=0.7/0.6*195=228Mpa；
According to the selection of the nominal strength of material and alternative materials, yield limit >=235MPa of final choice alternative materials.
Process route：Desulfurizing iron processing -- 120t converters --- LF stoves -- sheet billet continuous casting -- heating -- 1750mm rollings --
Section cooling -- cold-rolling pickling -- cold rolling mill -- the cold rolling rewinding of cold rolling cover annealing -- cold rolling levelling --.
Chemical composition：According to the method for design thin-walled sauce bucket cold-rolled steel sheet and the cold-rolled steel sheet composition range of offer, if
The actual constituent of family planning output product（Mass fraction, %）For：C0.15, Si0.091, Mn0.65, P0.021, S0.0046,
N0.0046, Al0.034, B0.00045.
Main points of rolling process：Hot rolling uses the hot rolling system of three high and one low, i.e. high-temperature heating, high temperature open rolling, high-temperature final rolling
Batched with low temperature.Complete recrystallization annealing is carried out using full-hydrogen hood-type annealing furnace in cold rolling process.
Performance comparison：The thickness produced according to the cold-rolled steel sheet of the method for design thin-walled sauce bucket cold-rolled steel sheet and offer
0.6mm plates yield strength 295MPa, tensile strength 437MPa, elongation percentage 33%.The yield strength 234MPa of original design 0.7mm plates,
Tensile strength 354MPa, elongation percentage 40%, yield strength is significantly improved.According to design thin-walled sauce bucket cold-rolled steel sheet
Method and the yield strength of the thickness 0.6mm plates yield strength ratio original design 0.7mm plates of the cold-rolled steel sheet of offer production have bright
It is aobvious to improve.
