Description
Technical field
The present invention relates to Tinplate, the manufacture method of the raw sheet of sheet iron of wuxi plate for surface treatment plate for can such as (TFS), once cooled thermal cycling does not change greatly when particularly relating to continuous annealing and can make respectively temper T1-T6 with the rolling manufacture method of making raw sheet once.
Background technology
Can classify by the temper that Rockwell T hardness (HR30T) is represented according to plate for surface treatment plate for can and raw sheet thereof that the Tinplate of JISG 3303 regulation and sheet iron of wuxi (TFS) are such.Wherein press temper T1～T6 classification with the goods and the raw sheet thereof of once rolling manufacturing, general T1～T3 is called soft material, and T4～T6 is called the hard material.
In the past, the raw sheet of soft material used intermittently to anneal and made, and the raw sheet of hard material uses continuous annealing (CAL) manufacturing, and recently, the raw sheet of a part of soft material becomes use CAL and makes.
Use the method for CAL manufacturing as the different raw sheet of temper, for example special opening in the clear 57-70227 communique adjusted to 3-1000 ℃/sec with the speed of cooling of CAL, in addition, make in the special fair 5-45653 communique in the process of cooling of CAL the average cooling rate between 500-400 ℃ be 55 ℃/sec following or 65 ℃/more than the sec, adjust the unit elongation of skin-pass again, and disclose the method that the raw sheet of temper T4 and T5 is made respectively.The spy opens and discloses the soft steel that will contain 0.02-0.10wt% phosphorus in the clear 60-92425 communique less than Ar
3The temperature hot rolling of transformation temperature, low temperature batches, speed of cooling among the CAL of cold rolling back is the above manufacturing hard material method of 30 ℃/sec, and in addition, the spy opens to disclose in the flat 4-80346 communique and carries out overaging according to reheat behind the chilling in CAL and handle the method for making soft material etc.
As to use change CAL in once cool off later thermal cycling method make raw sheet respectively with the wide region temper that covers from soft material to the hard material, heating, soaking, chilling, overaging, thermal cycling and heating that the soft material of refrigerative is used, soaking, slow cooling, the thermal cycling that the hard material of chilling is used is necessary, therefore no matter be that two special-purpose CAL are set respectively, the annealing device have the hard material and to use (for example cooling tube etc.) perhaps is set, the quenching apparatus that soft material is used (for example air-flow refrigerating unit and roll-type refrigerating unit etc.), the reheat of usefulness is handled in overaging, the large complicated CAL of attemperator etc. is necessary, in any case can cause that all installation cost and manufacturing cost increase greatly.
In addition, in the occasion of making the raw sheet of different tempers with the back at large complicated CAL respectively, according to the cooling conditions after the temper soaking a great difference is arranged, so the heat arch that causes by the difference of the gentle furnace temperature of plate after the direct change thermal cycling and take place easily that plate crawls, fracture, warpage, folding line etc., produce a large amount of invalid coil of strips, cause that productivity is low and qualification rate is low.
On the other hand, as the method for making raw sheet respectively with wide region temper from soft material to the hard material, the steel that adds extremely low C-Nb is used in suggestion in the Te Kaiping 2-197523 communique, and after making soft material with CAL, change the method for the unit elongation of skin-pass, in addition, the suggestion basis has or not the overaging processing of CAL and the method that the minor diameter working roll below the use 300mm makes up the unit elongation of anhydrous skin-pass in the public clear 60-10801 communique of spy.
; the method of Te Kaiping 2-197523 communique is owing to be necessary to carry out skin-pass with the high-elongation of 10～30% degree, the processibility of goods in making T4～T6 hard material; particularly ductility worsens significantly, the modified milling train that needs high-elongation to use again simultaneously.
In addition, the technology of special public clear 60-10801 communique, because making the different raw sheet of temper respectively is necessary to make up and has or not overaging to handle the thermal cycling of two classes, the usage quantity of invalid coiled material increases as mentioned above, cause that productivity is low, simultaneously owing to be necessary the overaging of carrying out more than 1 minute and handle that the overaging band is elongated, cost of equipment uprises.Moreover, owing to use the minor diameter working roll to carry out anhydrous skin-pass, when making soft material, carrying out skin-pass as low elongation with the 1-1.5% degree, it is too small that rolling load becomes, the stable rolling difficulty that becomes.
Disclosure of an invention
The objective of the invention is to solve above-described technical problem in the past, use the single CAL equipment of small inexpensive, do not reduce productivity and qualification rate, and provide use to stablize to make respectively the manufacture method of raw sheet of plate for surface treatment plate for can of use continuous annealing of the raw sheet of gamut temper from soft material to the hard material.
For achieving the above object; the manufacture method of the raw sheet of the plate for surface treatment plate for can of use continuous annealing has following operation; to contain below the C:0.1wt%; steel plate after the carbon aluminium-killed steel of N:0.001～0.015wt% cold rolling uses continuous annealing in the above temperature heating of recrystallization temperature; the operation of soaking; heating; after the soaking with greater than 100 ℃/sec; once be cooled to 350～480 ℃ operation less than the average cooling rate of 300 ℃/sec; finally cool off and carry out the operation of skin-pass after once the operation handled of the overaging of reheat and overaging are not handled after the cooling; and the temper according to hope more than recrystallization temperature changes soaking temperature; once cool off later thermal cycling and do not become, protect roughly certain with temper.
The best mode that carries out an invention
Describe manufacture method of the present invention below in detail.
C: its content is as surpassing 0.1wt%, because the steel plate overvulcanization, cold rolling shape control difficulty causes the reduction of the Flatness and the thickness of slab precision of steel plate.In addition, owing to cause that sheet material passes possibility of the mis-behave of milling train when continuous annealing is for this reason arranged, so be limited to below the 0.1wt%.
At this moment, can change C content, when making the soft material of modified amount T1～T3, below 0.05wt%, when making the hard material of temper T4～T6,, can more stably make the different raw sheet of temper as at 0.03～0.1wt% according to temper.
N: its content is as surpassing 0.015wt%, and with the same steel plate overvulcanization of situation of C, recrystallization temperature rises simultaneously, makes annealing temperature high temperatureization.In addition, owing to, can cause that steel-making cost increases, therefore be limited to 0.001～0.015wt% less than 0.001wt%.
The content of elements such as Si, Mn, P, S, solubility Al limits especially, in can be in the carbon aluminium-killed steel that common plate for surface treatment plate for can the uses contained scope.In addition, can add carbonitride forming elements such as B, Nb as required.
Generally, plate for surface treatment plate for can is that the carbon aluminium-killed steel of this sample ingredient is made slab, and is then with this slab hot rolling, cold rolling and make through annealing operation after the pickling.In the present invention, creating conditions before the CAL annealing had no particular limits, can be creating conditions of carrying out usually, that is, hot rolling is with 1050～1250 ℃ slab heating temperature, 830～900 ℃ processing temperature, and 500～700 ℃ coiling temperature carries out.Cooling roll can 80～95% draft carry out.In addition, also be suitable for without the method for process furnace steel billet directly rolling (HDR) or insertion backing (HCR).
At this moment, about coiling temperature, when making the raw sheet of temper T1～T3, as less than 600 ℃, carbide and AlN attenuate little, because its amount of separating out also reduces, steel plate is easy to sclerosis, and as surpassing 700 ℃, therefore the pickling deterioration is wished to carry out in 600～700 ℃.When making the raw sheet of temper T4～T6, as less than 520 ℃, the steel plate overvulcanization as surpassing 600 ℃, is easy to soften, and therefore wishes to carry out in 520～620 ℃.
According to CAL with heating, soaking, once cooling, overaging, final refrigerative thermal cycling with the steel plate annealing after cold rolling, change soaking temperature according to desirable temper, thereafter, thermal cycling does not become with temper, keep roughly certain, to surpass 100 ℃/sec, once be cooled to 350～480 ℃ less than 300 ℃ average cooling rates after, carry out the not overaging of reheat and handle, this is an inventive point of the present invention.Only change soaking temperature and change temper, and when overaging is handled, do not carry out reheat, use the single CAL equipment of small inexpensive, can not reduce the raw sheet that productivity and qualification rate are stably made the gamut temper from soft material to the hard material respectively.At this, do not carry out the overaging of reheat and handle, be meant once cooling off and do not carry out positive heat treated more than the terminal temperature, and in the processing of the degree of steel plate insulation, in fact the overaging band at CAL is provided with small-scale heating unit, carries out as usual user mode.
At this moment, one time the refrigerative average cooling rate surpasses 100 ℃/sec, reason less than 300 ℃/sec is: 100 ℃/can not give full play to quenching effect below the sec, C degree of supersaturation deficiency before overaging is handled is made soft material difficulty, simultaneously, speed of cooling has change for a short time, the material of hard material just has large deviation, and as be 300 ℃/ just need the big cooling apparatus of cooling power more than the sec, installation cost is increased.
In addition, refrigerative terminal temperature is that 350～480 ℃ reason is: handle in overaging and do not carry out in the thermal cycling of the present invention of reheat, as less than 350 ℃, the diffusion of C is incomplete, as above 480 ℃, the degree of supersaturation deficiency of C is utilized overaging to handle and is sought abundant softening difficulty, thereby can not make the raw sheet of the gamut temper from soft material to the hard material respectively.
Also have, a refrigerative method of cooling among the present invention can be the whole bag of tricks such as air-flow cooling in above-mentioned scope inner control speed of cooling, carbonated drink cooling, roll-type cooling, from cooling power, aspects such as refrigerative stability, manufacturing cost, plate surface quality see that the air-flow cooling is wished most.
When making the raw sheet of temper T1～T3, the soaking temperature of CAL is as less than 660 ℃, can not seek sufficient softening, as surpassing 780 ℃, the heating unit that essential heat is used causes the increase of installation cost and the increase of manufacturing cost, therefore wishes 660～780 ℃ of manufacturings.When making the raw sheet of temper T4～T6, as less than 600 ℃, remaining non-recrystallization tissue is given birth to the deviation that processibility reduces or produce material, and as surpassing 730 ℃, steel plate is softening, obtains the desirable temper difficulty that becomes, so 600～730 ℃ is desirable.
In addition, soaking time, as less than 5 seconds, grain growing is incomplete, easily becomes duplex grain structure, and it is big that the deviation of material becomes, and therefore wishes to guarantee more than 5 seconds., soaking time is long when essential above, material stable saturated, and the while body of heater need become greatly, then causes the increase of installation cost and manufacturing cost, and soaking time is that be desirable 20 seconds below the degree.
The overaging treatment time as more than 60 seconds, needs not only long but also big overaging band, causes the increase of installation cost and the increase of manufacturing cost, is desirable less than 60 seconds therefore.
Final refrigerative after overaging is handled begins temperature, and as less than 300 ℃, the diffusion of C is incomplete, and as surpassing 400 ℃, the degree of supersaturation deficiency of C is utilized overaging to handle and sought complete softening difficulty, so 300～400 ℃ is desirable.In addition, according to same reason, the inlet that overaging is handled and the temperature head of outlet, promptly once cooling off terminal temperature is more to wish below 100 ℃ with the difference that final cooling begins temperature.
The unit elongation of final cooled skin-pass, as less than 1.0%, the surface smoothness that obtains stipulating, Flatness, ageing resistance difficulty, as be more than 3.0%, not only processibility worsens, and guarantee that good thickness of slab distributes and the roller of Flatness directly diminishes and the variation of lubricating condition etc. necessitates, so more than 1.0%, be desirable less than 3.0%.
Be used as ETL or TFS circuit etc. according to the raw sheet of the plate for surface treatment plate for can of the inventive method manufacturing and go up and implement the surface-treated plate for surface treatment plate for can, also be suitable for the raw sheet of other plate for surface treatment plate for can of the raw sheet of making plating Ni steel plate etc.
Also have, hardness in the scope of 58≤HR30T≤60 repeats according to JISG 3303 temper T3 and T4, and temper T1～T3 is with HR30T＜59 in the methods of the invention, and temper T4～T6 distinguishes with HR30T 〉=59.
Embodiment
After becoming the carbon aluminium-killed steel A～T be grouped into the converter melting shown in the table 1, continuous casting and with the slab hot rolling that obtains after the pickling, is cold-rolled to thickness of slab 0.20mm.Slab heating temperature is 1150～1230 ℃ during hot rolling, and processing temperature is 860～900 ℃, and coiling temperature is according to changing shown in table 2 and the table 3.After cold rolling, press CAL annealing with condition shown in table 2 and the table 3 after, carry out skin-pass and make steel plate NO.1～22.Wherein, the NO.5 of annealing back reroll and the low NO.17 of soaking temperature of CAL are comparative example, and all other is an example.
Then, make the structure observation of steel plate, the HR30T measurement of hardness carries out tension test simultaneously and measures tension set EL.
The results are shown in table 2 and table 3.
In example of the present invention, as using the steel A～G below the C content 0.05wt%, can stably make the following soft material of temper T3, in addition,, can stably make the above hard material of temper T4 as using steel F～J of C content 0.03～0.1wt%.In addition, EL is high, and processibility is all superior.
On the other hand, the low also NO.17 of remaining non-recrystallization tissue of the comparative example NO.5 of reroll and the soaking temperature of CAL, EL is significantly low, poor in processability.
