1、 Pickling of wear-resistant copper castings.
The casting process of wear-resistant copper sleeve is complex, and the requirements are very strict, because once there are problems in the casting process, the copper sleeve will have defects or even waste products. When casting wear-resistant copper sleeve, attention should be paid to pickling treatment before processing. If the pickling is not carried out, the oxidation will easily lead to the peeling of the copper sleeve. The oxidation problem of copper sleeve is very serious, so this problem should be avoided in the casting process of wear-resistant copper sleeve.
