Process flow of copper alloy casting

①Raw 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。

②Melting: 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 。

③Test 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

④Centrifugal 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 。

⑤Lathe processing, boring, sand blasting: casting molding castings according to customer requirements after boring lathe processing, sandblasting, finished products, packaging completed

⑥Inspection warehousing
