Description
Technical field:
The present invention relates to the electric contact material technical field, refer in particular to a kind of processing technology of silver/copper double composite strip material.
Background technology:
Electric contact is the contact element of appliance switch, instrument and meter, it mainly bears the effect of connection and breaking current, it has decisive role to the safe operation of electrical equipment, in the material of producing electric contact, siluer metal oxide (as siller tin oxide AgSnO2, Agcdo AgCdO) material is owing to have anti-preferably electrical wear, resistance fusion welding and conductivity are used widely in low-voltage electrical apparatus.The two-sided composite material of silver tin/copper oxide is the new function material that is combined by special combination process by siluer metal oxide and two kinds of materials of copper, it had both kept the main characteristic of siluer metal oxide and base material copper, can obtain the not available performance of stock blend by complex effect again, silver, the anti-electrical wear of performance silver contact had both been saved, advantage such as resistance fusion welding and conductivity, can improve mechanical performance again, be an important joint silver technology.
Yet the bond strength of siluer metal oxide and copper is relatively poor, therefore, need have corresponding special process to process just and can make both strong bonded together, complements each other, and takes into account each other.At present domestic aspect composite material primary study the bar of yellow gold and oxygen-free copper compound, face is compound, there are indivedual factories testing the compound of siluer metal oxide and copper, the mode of production is for welding the edge of the siluer metal oxide plate ingot of 20mm and thick copper ingot two materials with argon arc welding earlier, then with heavy reduction rolling under the roughing mill, again through diffusion annealing repeatedly, the rolling combination that reaches different metal.This mode of production can not large-scale production, can only process the very little band of a segment length at every turn, utilizes this kind technology not process continuously, and production efficiency is extremely low.And along with the extensive use of electronic product, the demand of electric contact also increases day by day, and market prospects are very optimistic, but at present domestic production technology production efficiency is extremely low, the band poor bonding strength, and compound fastness is poor, and its production cost is high, can not satisfy the demand of existing market far away.
Summary of the invention:
The objective of the invention is to provide a kind of processing technology of silver/copper double composite strip material at the deficiencies in the prior art, this kind processing technology can process the silver/copper double composite strip material of rolling continuously, realize large-scale production, the production efficiency height, production cost is low, and the silver/copper double composite strip material bond strength height that is processed, compound fastness are good.
For achieving the above object, the present invention is achieved by the following technical solutions: it may further comprise the steps:
