Abstract
The invention discloses a production technology of a phosphor bronze belt material, comprising the following steps: a) horizontally continuous casting; b) evenly annealing; c) double-sided milling; d) cogging and rolling; e) middle annealing; f) rolling manufactured materials; g) cutting edges; h) secondary middle annealing; i) cleaning the manufactured materials; j) rolling leftover; k) annealing the leftover; l) rolling a finished product; m) annealing the finished product; n) cleaning the finished product; and o) straightening the strip shape, wherein, in the step I) of rolling a finished product, the press force of a hydraulic press cylinder of a finishing mill is 100-120 ton; and in the step m) of annealing the finished product, the temperature in the furnace is 180-200 DEG C, and the annealing time in the furnace is 3-5 hours. Because of adopting the above structure, the invention has the advantage of improving the yield strength of bronze so as to improve the material fatigue durability. The yield strength of the original annealing technology is 534, and the yield ratio is 0.85; and after the technology is improved, the yield strength is 594, and the yield ratio is 0.95 which is improved by 12%.
Description
Technical field
The present invention relates to phosphor bronze band technical field, particularly a kind of production technique of phosphor bronze band.
Background technology
The ratio of yield strength and tensile strength is called yield tensile ratio.YIELD STRENGTH is high more, and its anti-fatigue performance is good more.Therefore, require material usually under the constant prerequisite of tensile strength, have high yield strength, promptly require to improve the yield tensile ratio of material.Material with high anti-fatigue performance, its yield tensile ratio must reach about 0.95.And at present, the material that common tin-phosphor bronze production technique is made, its yield tensile ratio can only reach about 0.85, and the plug number of times of connector is less, and its work-ing life is shorter.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, to provide a kind of high-yield-ratio, have the production technique of the phosphor bronze band of high anti-fatigue performance.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of production technique of phosphor bronze band, may further comprise the steps: a) horizontal casting, b) homogenizing annealing, c) two-sided milling, d) split rolling method, e) process annealing, f) the system material is rolling, g) cutting edge, h) secondary process annealing, i) the system material cleans, j) keep on file rolling, k) keep on file to anneal, l) finished product is rolling, m) finished products, n) finished product cleans and o) straightening plate shape, described l) adopting finishing mill to keep on file in the rolling step of finished product, product is rolling is finished product, the power of depressing that the hydraulic pressure of described finishing mill is depressed cylinder is 100 tons～120 tons, described m) adopt bell furnace that finished product is annealed in the finished products step, temperature is 180 °～200 ° in the stove, and the furnace annealing time is 3～5 hours.
Described o) step after the straightening plate shape step is p) finished product itemize, q) finished product packing.
Described m) the furnace annealing time is 4 hours in the finished products step.
The present invention adopts aforesaid method, has the following advantages: 1, improved bronze yield strength, thereby improved the fatigue performance of material.The original annealing process of Shi Yonging, yield strength is 534, and yield tensile ratio is 0.85, and after the process modification, yield strength reaches 594, and yield tensile ratio reaches 0.95, has improved 12%; 2, improved the work-ing life of band.
