Description
Technical field
The present invention relates to titanium-steel composite board volume technical field, more particularly, relate to a kind of Titanium-steel composite board roll and production method thereof.
Background technology
Titanium-steel composite board is cheap, has the premium properties of titanium and Steel material concurrently simultaneously, is therefore just becoming the substitute of Titanium board and is applying in the field such as aviation, chemical industry.At present, most titanium-steel composite board is all adopt explosion method to produce.But there is the deficiency that cost is high and production kind is narrow in explosion method technique.
Direct superimposed accumulation rolling is that first Japanese researchers invents, and by the thin plate after surface treatment, lamination, repeatedly rolling reach seam repeatedly.Patent document CN102679134A discloses the technology with above-mentioned direct superimposed accumulation rolling basic simlarity.But, because direct superimposed accumulation rolling needs directly lamination, repeatedly rolling repeatedly reach seam, so the low and product of its production efficiency is based on tabular, the surface quality simultaneously during titanium-steel composite board product and Strip Shape Control function limited.
Summary of the invention
For at least one item in prior art above shortcomings, a kind of titanium-steel composite board is the object of the present invention is to provide to roll up and production method.
An aspect of of the present present invention provides a kind of method of producing titanium-steel composite board volume, and described method comprises the following steps of carrying out successively: heating titanium-steel composite board base, and its tapping temperature is controlled to be 980 ~ 1150 DEG C; Roughing, adopt the rolling of 5 passage modes, single pass reduction ratio is not less than 19%; Finish rolling, adopts continuous rolling process, and is controlled to be 930 DEG C ± 15 DEG C by entry temperature at finishing, is 760 DEG C ± 15 DEG C by finishing temperature control, mill speed is controlled to be 2.5 ~ 7m/s; Batch to obtain titanium-steel composite board volume, wherein, coiling tension adopts 8 ~ 25MPa.
In one exemplary embodiment of the present invention, the thickness of described titanium-steel composite board volume is 2.0 ~ 25.4mm.
In one exemplary embodiment of the present invention, described method adopts the hot rolling line be made up of heating furnace, reversing rougher, finishing mill, coiling machine to realize.
In one exemplary embodiment of the present invention, described hot rolling line is 2050 wide flat steel hot rolling lines.
Another aspect provides a kind of titanium-steel composite board volume, described titanium-steel composite board volume adopts method as above to obtain.
Compared with prior art, beneficial effect of the present invention comprises: improve titanium-steel composite board volume production efficiency, reduce production cost, workable, method simple, be easy to apply.
Detailed description of the invention
Hereinafter, titanium-steel composite board of the present invention volume and production method thereof will be described in detail in conjunction with exemplary embodiment.
The method of production titanium-steel composite board volume according to an aspect of the present invention comprises the following steps of carrying out successively: heating titanium-steel composite board base, and its tapping temperature is controlled to be 980 ~ 1150 DEG C; Roughing, adopt the rolling of 5 passage modes, single pass reduction ratio is not less than 19%, that is, roughing is rolled 5 passages back and forth, every time reduction ratio is not less than 19%, and this rolling mode has increases high temperature large deformation, reduces the benefits such as workpiece thickness; Finish rolling, adopts high temperature low speed continuous rolling process, is specially: being controlled to be 930 DEG C ± 15 DEG C by entry temperature at finishing, is 760 DEG C ± 15 DEG C by finishing temperature control, thus is conducive to rolling and carries out smoothly, avoids roll-force excessive; And mill speed is controlled to be 2.5 ~ 7m/s, thus can prevent from titanium-steel from causing in conjunction with separation tearing; Batch to obtain titanium-steel composite board volume, wherein, coiling tension adopts 8 ~ 25MPa.Adopt the combination of above-mentioned parameter to control, can obtain that there is good surface quality and roll up with the titanium-steel composite board in conjunction with effect.In addition, if roughing passage very little, reduction ratio is on the low side, easily causes intermediate blank thick, is unfavorable for distortion evenly; Speed too high (such as, more than 8m/s) easily causes titanium-steel to cause in conjunction with separation and tears.
In one exemplary embodiment of the present invention, the thickness of described titanium-steel composite board volume is 2.0 ~ 25.4mm.
In one exemplary embodiment of the present invention, described method adopts the hot rolling line be made up of heating furnace, reversing rougher, finishing mill, coiling machine to realize.Such as, described hot rolling line can be 2050 wide flat steel hot rolling lines.
Titanium-steel composite board volume according to a further aspect of the invention adopts method as above to obtain.
Below in conjunction with concrete example, one exemplary embodiment of the present invention are described.
In this example, band steel 2050 hot continuous rolling production line is adopted to realize method of the present invention.The capital equipment of this band steel 2050 hot continuous rolling production line can comprise: 1 ~ 4 walking beam heating furnace, 1 stand reversible roughing mill, 7 frame finishing tandem rolling units, 2 ~ 3 coiling machines.
In an exemplary embodiment of the method for production titanium-steel composite board volume of the present invention, described method comprises the steps such as blank heating is come out of the stove, roughing, finish rolling, coiling technique.Wherein, it is 980 ~ 1150 DEG C that titanium-steel composite board base tapping temperature controls, to ensure that slab still has sufficiently high temperature in finish rolling section after roughing temperature drop; Roughing adopts " 5 passage " mode rolling, and single pass reduction ratio is not less than 19%, to ensure that intermediate blank has good plate shape; Finish rolling adopts high temperature low speed, 7 frames (or passage) continuous rolling process, to ensure that titanium-steel Combined roll has good surface quality; Coiling tension adopts 8 ~ 25MPa, to ensure that titanium-steel composite board volume surface is without touching sassafras wound, scroll neat compact.
