Embodiment
Specific embodiments of the present invention are described below in detail.
A kind of stainless steel production steekle mill is used for the method for producing titanium plate, and its step is：
A) antioxidizing paint is coated to titanium plate slab, reduces titanium plate oxidization burning loss.
B) titanium plate slab is sent into heating stove heat, wherein furnace temp control is：850 DEG C of preheating zone, heating zone and
900 DEG C of soaking zone, air-fuel ratio 1.25；And insulation material slab is placed on feed device before and after titanium plate slab；To ensure titanium plate
Load the forward and backward heating in-furnace temperature of heating furnace to be consistent substantially, temperature fluctuation is small.
C) dephosphorization apparatus closed in roughing equipment, titanium plate slab enter roughing equipment and carry out 5 passage roughing processing, wherein
Width drafts≤10mm of roughing equipment, a width is led in roughing side increases 5mm compared with stainless steel plate, to adapt to when titanium plate rolls more
Big calendering fluctuation, roughing horizontal roll roll gap level error are -4.00~+4.00mm, and the control of roughing outlet temperature is 870 DEG C；1
~3 passage slab stop position length are 6m, and during rolled stainless steel 1~3 passage slab stop position length be 1.5~
5.0m, increase stop length and make it that titanium plate recovery and recrystallization is more abundant；
Roughing discharge when, traveling crane weight by titanium plate head raise up part flatten.
D) the titanium plate slab after roughing enters precision rolling equipment progress 5 passage finish rolling processing, and titanium plate calendering load is small, and passage subtracts
Rare profit and the strip threading slot of volume stove milling train and the risk of calendering production；
It is 900 DEG C wherein to roll up stove Control for Kiln Temperature；Finishing mill working roll roll neck uses 680mm, roll diameter of roller be not easy it is too small, it is no
Then easily there is Yang Wenti up and down in titanium plate；
Because titanium plate is softer, the strong drafts of roll gap is adjusted to 0~1.50mm；And strong drafts is during rolled stainless steel:0~
3.00mm。
Automatic thickness control pressure feedback module coefficient adjustment is 5.0%~20% so that titanium plate thickness is more after rolling
Uniformly；
Flying shear sheared length is 750mm after finish rolling, and titanium plate afterbody shearing detection error is big, so amplifying sheared length in right amount
Setting.
E) it is that titanium plate sheet material is sent into crimping machine packing in rolls by 120mpm that finishing mill, which throws steel speed control, so that titanium plate crimps
Elasticity is suitable.Crimping machine tension adjustment is 0.55~2.4N/mm2；Crimping machine curling Withdrawal roll pressure is adjusted to 5.0~8.0
Ton, crimping machine Wrapping Roll pressure are adjusted to 4.0~5.5 tons, to ensure that titanium plate curling scroll is good；
In addition, each unit side of steekle mill is led and side leads idler roller and smears high-temperature grease, to avoid titanium plate side surface from wearing.
The principle and its effect of the above embodiments only illustrative the invention, and the implementation that part uses
Example, not for the limitation present invention；It should be pointed out that for the person of ordinary skill of the art, wound of the present invention is not being departed from
On the premise of making design, various modifications and improvements can be made, these belong to protection scope of the present invention.
