Placement steel billet material around titanium blank, what wherein contact with titanium blank upper surface is base-material on steel billet material, what contact with titanium blank lower surface is base-material under steel billet material, along the setting of titanium blank circumferential direction is steel billet material strip of paper used for sealing, on described steel billet material, under base-material, steel billet material, base-material and steel billet material strip of paper used for sealing form a relative airtight space, described titanium blank is arranged in this relatively airtight space, between both ends on described titanium charge length direction and steel billet material strip of paper used for sealing, there is gap, to give titanium blank lateral extension space freely;
(3) spot welding sizing: manual welding, gas shielded arc welding, argon arc welding can be adopted the spot welding sizing of having combined blank, guarantee that the relative position of blank can not be moved before handling enters next process;
(4) weld: by all faying face edges welded seal of the assembly blank after sizing.
Further, in the step (1) of the manufacture method of the blank for the production of steel titanium composite panel of the present invention, through the flatness≤1mm/m of the faying face to be welded of all blanks of surface preparation
2, guarantee that seal welding quality meets the demands.
Further, in the step (1) of the manufacture method of the blank for the production of steel titanium composite panel of the present invention, through roughness Ra≤12.5 μm of the faying face to be welded of all blanks of surface preparation, guarantee the heating rolling welding quality that steel titanium composite billet is follow-up.
Further, in the step (2) of the manufacture method of the blank for the production of steel titanium composite panel of the present invention, the width of steel billet material strip of paper used for sealing is 15-80mm.This width range is can ensure that weld strength reaches the Weld strength requirement needed for subsequent heat rolling.It should be noted that, because when assembly, the outer edge of steel billet material strip of paper used for sealing is concordant with base-material on steel billet material with the outer edge of base-material under steel billet material, therefore the width of steel billet material strip of paper used for sealing refers to the size extended towards the direction of titanium blank from the outer edge of steel billet material strip of paper used for sealing (or on steel billet material under base-material/steel billet material the outer edge of base-material) herein.
Further, in the step (4) of the manufacture method of the blank for the production of steel titanium composite panel of the present invention, adopt vacuum electron beam welding.Vacuum electron beam welding can make steel titanium weld and realize dark molten seal welding (welding seam deep width ratio can be greater than 20:1), farthest can not only reduce the heat affected area of blank, and can weld strength be ensured, avoid composite surface in following process process can not because weld seam gas leakage and oxidized.
Further, in the step (4) of the manufacture method of the blank for the production of steel titanium composite panel of the present invention, welding vacuum≤0.1Pa.This vacuum values effectively can prevent the formation of steel titanium surface oxide layer, reduces vacuum pumpdown time simultaneously, improves working (machining) efficiency, reduce processing cost.
Further, in the step (4) of the manufacture method of the blank for the production of steel titanium composite panel of the present invention, the depth of weld is 10-80mm.This depth of weld can ensure that weld strength reaches the Weld strength requirement needed for subsequent heat rolling.
Further, in the step (4) of the manufacture method of the blank for the production of steel titanium composite panel of the present invention, weld width >=2mm.This weld width can ensure that weld strength reaches the Weld strength requirement needed for subsequent heat rolling.
Further, the manufacture method of the blank for the production of steel titanium composite panel of the present invention also comprises step (5): welding stress is eliminated and seam inspection inspection.Electric and magnetic oscillation can be used to eliminate welding stress.Estimating defective welding position can be perfect with manual electric arc welding repair welding.
In the technical program, it is obtained that the steel billet material strip of paper used for sealing related to can adopt hot-rolled steel channel, U-shaped cold-rolled forming section to process.
The manufacture method production efficiency of the blank for the production of steel titanium composite panel of the present invention is high, and cost is low, and composite effect is good, applied widely, easy to process.Adopt the method can prepare thickness 10-1000mm, the steel-titanium of width 400-2000mm, length 2000-3500mm, the blank of steel-titanium-steel composite board.Metal material rolling, forging processing enterprise also can according to self process equipment condition and client's needs, by steps such as follow-up rolling, forging, processing, finishing, can based on published metal diffusion welding (DW) mechanism, determine rolling mill practice flexibly according to own heating, rolling, Equipment for Heating Processing, produce the steel-titanium composite panel within the scope of business equipment capacity limit, steel-titanium-steel composite board and steel-titanium forging, steel-titanium-steel forgings further.
