Excuse me, what is the problem with copper polishing material
3, in the production process of improper operation, the water temperature of copper melting furnace is not high down, then put in the holding furnace temperature rise, the copper made at that time in the heating have small impurities (this is only part of copper impurity).In which case do you consider it yourself?..
There are words and copper impurities for 3 reasons:1, copper water temperature is not high enough, some small impurities did not melt.2, the material is difficult to melt (such as copper sand)
Polishing is not a material requirement, but a requirement for temperature and material,First of all, polished copper production, when it is best to use copper powder, such as the production of A bar, the water tank can be, but absolutely can not use copper sand, because copper sand is difficult to melt, so produced copper has some small impurities or trachoma, there is a temperature, high temperature, can put all small impurities have melted into the bar to go inside, to throw the polishing up.
