Production process of beryllium bronze strip material

Abstract

The invention discloses a production process of a beryllium bronze strip material, which particularly includes the following steps: 1) selecting beryllium bronze material at high grade, melting the material at high temperature for 1 h to obtain molten electrolytic copper; 2) adding platinum and fully stirring the melt until the platinum is completely dissolved; 3) drossing the mixture melt in thestep 2); 4) discharging the mixture melt in the step 3), and cooling and shaping the mixture melt; 5) feeding the cooled and shaped cubic material in the step 4) into a furnace and performing heat preservation at 780 DEG C for about 10 h; 6) performing blowing-in hot rolling to the bronze bulk green body in the step 5) to form thin plate in 6.5 mm, performing twin-roller hot-rolling to 1.8 mm, andcoiling the hot-rolled strip material to obtain a workblank; 7) performing high temperature annealing to the workblank in the step 6) on a car bottom furnace. In the whole production process, temperature and steps are strictly controlled, and multi-time annealing is employed to increase hardness of the beryllium bronze strip material; in addition, by means of ammonia gas as protection atmospherein the annealing, when the ammonia gas is decomposed, oxidization of the product is prevented and production quality is effectively improved.

Description

technical field [0001] The invention relates to the technical field of production and processing of beryllium bronze strips, in particular to a production process of beryllium bronze strips. Background technique [0002] Beryllium bronze alloy is an alloy with good mechanical, physical and chemical properties. After quenching and tempering, beryllium bronze material has high strength, elasticity, wear resistance, fatigue resistance and heat resistance. It has high electrical conductivity, thermal conductivity, cold resistance and non-magnetism. Beryllium copper material has no spark when it hits. Beryllium copper is easy to weld and braze. It has excellent corrosion resistance in the atmosphere, fresh water and sea water. Beryllium copper alloy is A rare alloy. [0003] Beryllium copper strip can be used to make electronic connector contacts, various switch contacts, and important key components, such as diaphragms, diaphragms, bellows, spring washers, micro-motor brushes a...
