Abstract
A method for welding double layers of stainless steel sheets to steel blank by exploding once features that two layers of stainless steel sheet with thickness great than 16 mm (the thickness differrence between two layers is less than 4 mm) are put on the steel blank with gaps between the first layer, the second layer and the steel blank, two supporters are put in the gaps, the weight of explosive is 0.2-0.3 times that of double layers of stainless steel sheet, and the exploding speed of explosive is 1800-2800 m/s. Its advantages are high quality of product and productivity and low cost.
Description
The present invention relates to a kind of manufacture method of composite metal plate, especially the method for stainless steel composite base.
Make the method for stainless steel composite base at present, mainly contain two kinds:
(1) thick corrosion resistant plate directly is welded on the steel billet with the explosive welding (EW) connection among the general, this method shortcoming is that explosive consumption is very big, and stainless steel is very big to the steel billet impulsive force, steel billet especially bloom is difficult to keep out, crackle often appears, even fracture, be difficult to ensure the quality of products, and the thick corrosion resistant plate adjustment very trouble of getting up also.
(2) thick corrosion resistant plate divides secondary to carry out explosive welding among the general, as patent CN1025947C,, reduce as explosive charge though this method makes progress than first method, thin stainless steel adjustment gets up to want easily, but yet have shortcoming: 1) divide the subsequent explosion welding, steel billet will be subjected to secondary pulse, so more impaired chances of steel billet, because steel billet is continuous casting billet especially, performance is very unstable, cracking often occurs, so loss percentage is very high.2) divide the subsequent explosion welding efficiency very low, after the ground floor explosive welding is intact, a lot of problems can occur: as the steel billet cracking, steel billet distortion or steel billet are compound bad.So just make very difficulty of second layer explosive welding process progress.Ftracture as steel billet, after steel billet will being carried out repair welding and finishing, carry out second layer explosive welding process again, and the blast place generally in the open air, steel billet will be transported back in the processing factory like this and be handled, and then transport the mountain and carry out second layer explosive welding, so to want sometimes to carry out second layer explosive welding immediately be impossible, therefore make produce in enormous quantities very difficult.
The purpose of this invention is to provide a kind of on steel billet the method for explosive welding double-deck stainless steel once.The inventive method improves explosive welding composite steel billet production efficiency greatly, and the composite steel billet quality is guaranteed, and can realize the production in enormous quantities of composite steel billet.
To achieve these goals, the present invention has taked following method:
Steel billet is placed on the blast basis,, on steel billet, puts double-deck stainless steel, leave the gap between steel billet and second layer corrosion resistant plate and ground floor corrosion resistant plate and the second layer corrosion resistant plate, be placed with support between every lamellar spacing as on the soil or on the sand base.
Topmost is to place buffer protection layer, explosive and detonator on the ground floor corrosion resistant plate.The thickness of steel billet is greater than double-layer stainless steel plate thickness sum, gap between ground floor corrosion resistant plate and the second layer corrosion resistant plate is 0.8-1 a times of ground floor corrosion resistant plate thickness, and the gap between second layer corrosion resistant plate and the steel billet is 0.3～0.6 times of second layer corrosion resistant plate thickness.The thickness sum of double-deck stainless steel is 16mm-30mm, and two-layer corrosion resistant plate thickness difference should be not more than 4mm.
Charge weight is 0.2～0.3 times of double-deck stainless steel weight, and explosion velocity of explosive is between 1800m/s-2800m/s.
The steel billet that the present invention uses can be a bloom.
The method of an explosive welding double-deck stainless steel of the present invention has following advantage:
(1) whole preliminary preparations of explosive welding composite steel billet can be carried out in processing factory, various like this technological parameters, quality just can guarantee.
(2) significantly reduced the influence of rarefaction wave to steel billet, the cracking phenomena that steel billet is often occurred is eliminated substantially.
(3) operating efficiency is significantly improved, production cost reduces significantly, and the production capacity of stainless steel composite base is significantly improved, and has created prerequisite for producing the stainless steel composite base in enormous quantities.
Embodiments of the present invention is described in detail below in conjunction with accompanying drawing:
Fig. 1 is relative position schematic diagrames such as steel billet before the cap sensitive of the present invention, corrosion resistant plate.
Fig. 2 is the vertical view of Fig. 1.
Among the figure:
The 1-electric cap; The 2-explosive; 3-medicine-chest, 4-protective layer, 5-ground floor corrosion resistant plate; 6-second layer corrosion resistant plate; The 7-supporter; The 8-steel billet; 9-weak soil basis (i.e. blast basis); The 10-supporter.
As shown in the figure, composite thickness is two corrosion resistant plates 5 and 6 of 12+10mm, its gross thickness is 22mm, at thickness compound above-mentioned two block length 1000mm on the steel billet of 120mm, wide 1000mm, gross thickness is the double-deck stainless steel 5 and 6 of 22mm, and (1) is placed on steel billet 8 on the weak soil basis 9 as substrate earlier.(2) supporter 10 being placed on above the steel billet 8, is that the corrosion resistant plate 6 of 10mm is placed on the supporter 10 as second layer corrosion resistant plate again with thickness, and gap 10 is 6mm between steel billet 8 and the second layer corrosion resistant plate 6.(3) place supporter 7 on corrosion resistant plate 6, the corrosion resistant plate 5 with thickness 12mm is placed on the supporter 7 again, and the gap between ground floor corrosion resistant plate 5 and the second layer corrosion resistant plate 6 is 10mm.(4) on ground floor corrosion resistant plate 5, put cushion 4 (with pitch or malthoid), put medicine frame 3 then, put into the explosive that weight is 45kg, put detonator 1 at last, ignite then, moment, on steel billet, composite stainless steel plate gross thickness was 22mm with the double-deck stainless steel explosive welding.
In the above-described embodiments, the explosion velocity of explosive is got 2500m/s～1800m/s, for the stainless steel composite base, thickness＞the 16mm of the double-deck compound plate of general stainless steel, double-layer stainless steel can be with approximate combination like this, that is: 8+8=16,8+10=18,10+12=22 etc., two-layer corrosion resistant plate thickness is more or less the same in 4mm.
