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 method of composite stainless steel plate; it is that substrate is positioned on the sand basis; placing between stainless steel compound plate and described substrate makes both keep the supporter of certain interval; on described compound plate, place the buffer protection layer; explosive and detonator are placed on the described protective layer; ignite described detonator; it is characterized in that: described substrate is a continuous casting billet, and described compound plate goes out 10-30mm greatly than the every limit of described substrate, and the gap between described compound plate and the substrate is the doubly thickness of described compound plate of 1-1.2; described explosive is the ammonium nitrate-fuel oil mixture that contains diesel oil 6%-10%; the amount of described explosive is the doubly weight of described compound plate of 0.3-0.5, and described compound plate thickness divides two-layer compound during greater than 18mm; after ground floor is compound; carry out 100% flaw detection, postwelding is repaiied at not compound place, it is compound to carry out the second layer again.
For guaranteeing composite quality, by the size fluting of described substrate, described groove depth is the thickness of 50-70% compound plate on the described compound plate, and groove width is 4-6mm.
Described explosive also can adopt rock explosive+30%NaCl No. 70%2.
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.
