Copper Alloy Casting Introduction
Process flow of copper alloy casting
1.Raw material preparation: First of all, the chemical composition of raw materials analysis, the inspection of qualified raw materials to be adopted, the inspection of raw materials returned to be returned. Then, according to the raw material ratio calculation, structure weighing various raw materials.
2.Melting: Adding raw materials to the furnace according to a certain order and proportion of materials. If 88% copper is added into the furnace and heated into liquid, then 10% zinc and 1% lead are added into the furnace to stir evenly, so that the furnace temperature is consistent, and after 30 minutes it reaches 1200 degrees. After melting, the copper slag remover is used for preliminary slag removal.
3.Test before casting: After preliminary slag cleaning, sampling and testing, the results and product standards within 0.5%, and then add the required elements according to customer requirements.
4.Centrifugal casting: The copper water into the centrifugal casting machine, centrifuge speed control at 1000 to /min, temperature control at 1100-1200 degrees Celsius, 10 minutes after cooling to 500-600 degrees Celsius, pouring into the casting machine release agent, after cooling to take out the finished product.
5.Lathe processing, boring, sand blasting: casting molding castings according to customer requirements after boring lathe processing, sandblasting, finished products, packaging completed.
a. Complete production facilities: Owning Two sets of 3 tons induction furnace, One set of mid-frequency induction electrical furnace with 2000kg, One set of mid-frequency induction electrical furnace with 1500kg, Two sets of trolley resistance-heated electrical furnace with 2200 x 1200 x 650mm, Two sets of well tempering electrical furnace with ф1300 x 1700mm. Our technicians will do regular scheduled maintenance on these machines to guarantee them work well.
b. Technology Support: We have distinguished wear-resistant experts at home and abroad, which are engaged in research of anti-wear materials and innovation of wear-resisting casting products. We have cooperated with Tianjin Cement Research & Design Institute to improve the production of cement mills with our boltless lining technology. We have cooperated with Shanghai Silicate Research Institute under Chinese Academy of Sciences to develop ceramic boltless mill liners.
