The purpose of this invention is to provide a kind of decked explosion, and with suitable dose proportioning compound big thickness stainless steel compound plate on continuous casting billet, with the method for the stainless steel clad plate of making the big compound ratio of large tracts of land.
For achieving the above object; the present invention has taked following method: a kind of on continuous casting billet the method for composite stainless steel compound plate; it is that substrate is placed on the sand basis; between stainless steel compound plate and described substrate, place supporter; make both keep certain interval; place the buffer protection layer on described compound plate, explosive and detonator are placed on the described buffer protection layer, ignite described detonator.It is characterized in that: described substrate is a continuous casting billet, gap between described compound plate and the substrate is the doubly thickness of described compound plate of 1-1.2, the dose of described explosive is the doubly weight of described compound plate of 0.3-0.5, the thickness of described compound plate is during greater than 18mm, compound at twice, after for the first time compound, carry out 100% flaw detection, postwelding is repaiied at not compound place, and it is compound to carry out the second time again.
Be to guarantee composite quality, make wherein compound plate area greater than described substrate, its every limit goes out 10-30mm greatly, and on described compound plate by the size fluting of described substrate, described groove depth is the thickness of 50-70% compound plate, groove width is 4-6mm.
The present invention is owing to the method that adopts at the compound big thickness stainless steel compound plate of continuous casting billet higher slice, for the stainless steel clad plate of producing the big compound ratio of large tracts of land in enormous quantities has been created condition.Owing to adopt the design of suitable explosive consumption and compound plate greater than substrate, make continuous casting billet can produce neither that matrix damages or the edge is pulled, guarantee that again combined strength bination and recombination rate reach requirement, simultaneously owing to the design of having taked on compound plate, to slot, explode compound after, the redundance of compound plate can cut off automatically.The composite continuous casting base that adopts the present invention to make can be widely used in oil through rolling, and chemical industry is in the industries such as light industry and space flight.
