Description
Technical field
The invention belongs to the electrolytic etching of metal equipment technical field, be specifically related to a kind of restorative procedure of titanium starting sheet.
Background technology
Electrolytic etching of metal is to be that motherboard begins to produce the beginning step by kind of a plate, carries out electrolysis by the beginning step again and forms, so the quality of electrolytic metal plate be decided by the to begin quality of step, at present, electrolytic nickel mainly uses titanium starting sheet production beginning step.Titanium starting sheet is compared with copper kind plate, Stainless Steel Blank etc.; Have light weight, corrosion-resistant, long service life, without characteristics such as separant, electrolytic nickel quality height; But because the titanium starting sheet price is higher; Need recycling just can reduce cost, and existing technology can not be accomplished the reparation to waste and old and incomplete titanium starting sheet, can not satisfy the demand of titanium starting sheet recycling.
Summary of the invention
The technical problem that the present invention solves: a kind of restorative procedure of titanium starting sheet is provided, can accomplishes reparation,, prolong the work-ing life of titanium starting sheet, reduce the use cost of titanium starting sheet to satisfy the demand of titanium starting sheet recycling to waste and old and incomplete titanium starting sheet.
The technical scheme that the present invention adopts: a kind of restorative procedure of titanium starting sheet comprises following process step:
1) the incomplete position of waste and old or incomplete titanium starting sheet is trimmed to the geometrical shape of rule and cleans out through metal cutting technology becomes titanium starting sheet to be repaired; Waste and old or the incomplete titanium starting sheet of same model is trimmed to the geometrical shape that matches with said incomplete position and cleans out through metal cutting technology becomes subsequent use sheet material;
2) with of the corresponding incomplete position splicing of said subsequent use sheet material, make the two shape match back and butt seam position gas shield welding, then the weld is polished flat, form the titanium starting sheet that geometrical shape is complete with titanium starting sheet to be repaired;
3) said geometrical shape is complete titanium starting sheet successively fitly is deposited on the lower bolster; The top placement upper padding plate of last layer; And through thru-bolt lower bolster and upper padding plate four jiaos are connected and fix; Stacking height can be confirmed according to the height of heat treatment furnace, be advisable to guarantee the effective heating warm area height that is no more than heat treatment furnace.
4) whole stacking is sent into heat treatment furnace, according to the characteristic that is processed titanium starting sheet, can select recrystallization annealing temperature or stress relieving temperature to heat-treat, how many soaking times is confirmed according to characteristic that is processed titanium starting sheet and batch;
5) whole being stacked in the stove after the thermal treatment taken out behind the naturally cooling, and carry out moulding piecewise and be trimmed to and meet the requirements;
6) with the consistence of the titanium starting sheet pickling that trims with the assurance product surface;
7) adopt gas protection welding process on the titanium starting sheet after the pickling, to weld otic placode and become the finished product titanium starting sheet;
8) to finished product titanium starting sheet check back packing.
Pure titanium starting sheet for repairing for the first time is heated to 850 ℃ ± 50 ℃ of transformation temperatures, be incubated about 1 hour, naturally cools to 200 and comes out of the stove below spending; Pure titanium starting sheet for repeated multiple times is repaired is heated to 650 ℃-730 ℃, be incubated about 1 hour, naturally cools to 200 and comes out of the stove below spending.
The height of every buttress is controlled in 100 layers.
The centre of every buttress is provided with middle backing plate, and connects fixing with four jiaos of lower bolster, middle backing plate and upper padding plate successively through thru-bolt.
Metal or non-metallic material that said lower bolster, middle backing plate and upper padding plate select for use intensity to be higher than pending metal are manufactured, and carry out surface grinding, and the roughness on backing plate surface, polishing back should be less than 3mm; The length and width of backing plate are respectively greater than titanium starting sheet length and width 20～50mm, and plate thickness is guaranteed under thermal treatment process, not occur bending and deformation or rupture.
The present invention is compared with prior art through operations such as finishing, splicing, thermal treatment, shapings; Completion is to the reparation of waste and old and incomplete titanium starting sheet; And the titanium starting sheet after repairing can reach the technical requirements of novel species plate fully; Satisfy the demand of titanium starting sheet recycling, prolonged the work-ing life of titanium starting sheet, reduced the use cost of titanium starting sheet.

Embodiment
Below in conjunction with accompanying drawing 1,2 a kind of embodiment of the present invention is described.
A kind of restorative procedure of titanium starting sheet comprises following process step:
1) the incomplete position of waste and old or incomplete titanium starting sheet is trimmed to the geometrical shape of rule and cleans out through metal cutting technology becomes titanium starting sheet 1 to be repaired; Waste and old or the incomplete titanium starting sheet of same model is trimmed to the geometrical shape that matches with said incomplete position and cleans out through metal cutting technology becomes subsequent use sheet material 2; Expand 10-15mm again along said incomplete position outer contour during cutting and cut, remove the zone of influence, incomplete position, to guarantee the repairing quality of titanium starting sheet.
2) with of the corresponding incomplete position splicing of said subsequent use sheet material 2, make the two shape match back and butt seam position gas shield welding, then the weld is polished flat, form a titanium starting sheet 3 that geometrical shape is complete with titanium starting sheet 1 to be repaired;
3) said geometrical shape is complete titanium starting sheet 3 successively fitly is deposited on the lower bolster 4; Backing plate 8 in the 50th layer the top placement; In the top of backing plate 8 successively fitly stack 50 layers again, the top placement upper padding plate 5 of last layer, and connect fixing with four jiaos of lower bolster 4, middle backing plate 8 and upper padding plate 5 successively through thru-bolt 6; Stacking height also can be confirmed according to the height of heat treatment furnace, be advisable to guarantee the effective heating warm area height that is no more than heat treatment furnace.
4) whole stacking being sent into the resistance-type process furnace heat-treats; According to the characteristic that is processed titanium starting sheet; Can select recrystallization annealing temperature or stress relieving temperature to heat-treat, how many soaking times is confirmed according to characteristic that is processed titanium starting sheet and batch; Pure titanium starting sheet for repairing for the first time is heated to 850 ℃ ± 50 ℃ of transformation temperatures, be incubated about 1 hour, naturally cools to 200 and comes out of the stove below spending; Pure titanium starting sheet for repeated multiple times is repaired is heated to 650 ℃-730 ℃, be incubated about 1 hour, naturally cools to 200 and comes out of the stove below spending.Above-mentioned technology can be adjusted the tissue and the mechanical property of weld seam agent heat affected zone on the one hand, under pure titanium transformation temperature, makes creep under variable stress with the sheet material leveling through pressurization on the other hand, can obtain the sheet material of roughness≤3mm.
