Abstract
The invention discloses a technique for manufacturing square molybdenum plates with high creasing resistance, which comprises the following steps: firstly, a molybdenum blank undergoes rolling for three times and is cut into blocks, and the width of the blocks of the molybdenum blank is between 75 and 80 millimeters; secondly, the blocks of the molybdenum blank undergo rolling for three times, and are rolled into blocks with the thickness of between 0.45 and 0.5 millimeter; thirdly, the blocks are punched into square molybdenum plates with various specifications; and fourthly, the square molybdenum plates are washed clean. The square molybdenum plates prepared by the manufacturing technique have high creasing resistance, and can not generate delamination and cracking after undergoing right-angle (90 DEG) bending for two times; and the technique is simple and is easy to realize.
Description
Technical field
The present invention relates to a kind of manufacturing process of metal material, be specifically related to a kind of manufacturing process of high-anti-molybdenum square tablet.
Background technology
Power semiconductor device is used gradually and is developed to the second generation, the third generation, and molybdenum side's sheet is an indispensable important composition part in the components and parts.But at present domestic production molybdenum side sheet delamination splitting promptly occurs by a right angle (90 spend) bending, influences element service life.The common molybdenum side of market demands sheet transforms to high-anti-molybdenum square tablet.
Summary of the invention
Technical problem to be solved by this invention provides a kind of manufacturing process of high-anti-molybdenum square tablet, also delamination splitting can not occur after sheet process secondary right angle, molybdenum side (90 degree) bending by this technology manufacturing.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of manufacturing process of high-anti-molybdenum square tablet, it comprises the steps:
(1) the molybdenum base is rolled into the thick molybdenum plate of 7～8mm 1250～1300 ℃ of following heat tracings 70～80 minutes;
(2) molybdenum plate is rolled into the thick molybdenum plate of 3～3.5mm 1050～1150 ℃ of following heat tracings 60～70 minutes;
(3) molybdenum plate is rolled into the thick molybdenum sheet of 1.8～2mm 900～1050 ℃ of following heat tracings 30～40 minutes;
(4) molybdenum sheet is sheared piecemeal, make that width is 75～80mm, helps the tandem rolling of molybdenum sheet like this;
(5) molybdenum sheet is 800～900 ℃ of following heat tracings 30～40 minutes, and it is thick that molybdenum sheet is rolled into 1.2～1.3mm;
(6) pickling promptly uses the acetic acid of 20～30% (v/v) to clean;
(7) molybdenum sheet is 400～450 ℃ of following heat tracings 40～50 minutes, and it is thick to be rolled into 0.7～0.8mm;
(8) molybdenum sheet is at 820～860 ℃ of following annealing heat tracings 60～70 minutes, and it is thick that molybdenum sheet is rolled into 0.45～0.5mm;
(9) molybdenum sheet is become molybdenum side's sheet of all size through the punch press punching out;
(10) clean.
Beneficial effect: the molybdenum side's sheet by manufacturing process preparation of the present invention has high anti-folding characteristic, also delamination splitting can not occur after process secondary right angle (90 degree) bending, and process is simple, is easy to realize.
The specific embodiment:
According to following embodiment, the present invention may be better understood.Yet, those skilled in the art will readily understand that the described concrete material proportion of embodiment, process conditions and result thereof only are used to illustrate the present invention, and should also can not limit the present invention described in detail in claims.
