Background technology
Easily there is face crack and raw edges phenomenon during the rolling process in titanium or titanium alloy slab, this greatly reduces into
Product rate.By coating layer protective layer in alloy steel slab surface, alloy sheets checking line can split during effective controlled rolling
Side phenomenon, and reconditioning quality can be substantially reduced, rate must be expected by improving product.
The method for generally using explosive-clad at present realizes the cladding of titanium alloy slab.Although explosive-clad has compactness
High, the advantages that bond strength is high, but in actual production, explosive-clad influenced by weather condition it is very big, not environmentally, the duration
Length, cost are higher.And there is explosive-clad certain unstability, the huge energy for generation of exploding may damage slab, make
At slab crackle, or even the serious harmful effect such as broken.
Invention content
It is very big the purpose of the present invention is being influenced to solve explosive-clad by weather condition, not environmentally, long in time limit, cost compared with
It is high.And there is explosive-clad certain unstability, the huge energy for generation of exploding may damage slab, slab is caused to split
Line, or even the problem of the serious harmful effect such as broken, a kind of utilize is provided and welds sandwich rolling technology production titanium or titanium alloy plate
The method of material.
