Points to be paid attention to by the upper priming operator

Operator should pay attention to matters
1. Regular daily maintenance of mold. Descaling and cleaning, to ensure smooth waterways; 2. Before entering the furnace, the electrolytic copper must be clean. It must be baked on the furnace to preheat and remove moisture.
3, feeding must be balanced, to add less frequently, keep the furnace temperature constant and stable copper liquid level, and add copper or copper scrap material, can not float on the surface of liquid copper, to timely use the rod pressed into liquid copper.
4, charcoal must be baked before the furnace, charcoal covering layer must be tight, and maintain enough thickness, avoid copper liquid inhalation of oxygen and hydrogen in the air; 5. Slag removal and carbon exchange must be carefully operated according to process specifications to avoid copper liquid exposure to air inhalation.
6. Regularly remove furnace wall hanging slag to prevent harmful substances from melting into copper liquid again; 7, should always pay attention to observe the quality of copper rod, copper liquid level height and charcoal coverage and changes in the process parameters. If abnormal quality of copper rods is found, timely measures should be taken to deal with them.
To sum up, the oxygen free copper rod pores are caused by comprehensive factors, any negligence in the production of each link will cause pores, can not say which link is particularly important, can only say that no link is not important. Only WITH SUFFICIENT GUARANTEE FROM RAW MATERIALS, TECHNOLOGY, EQUIPMENT, ENVIRONMENT AND PERSONNEL QUALITY CAN THE porosity OF COPPER ROD BE REDUCED. So what links should we focus on at present? According to my follow-up observation on the production link and product quality of up-drawing copper rod in recent years, there is still a gap between the sorting and classification of scrap copper wire before packaging and the requirements of "Quality Control Regulations on Scrap Copper Packaging Process". Its management needs to be strengthened and PERFECTED. We believe that with our joint efforts, the quality of the upper lead oxygen free copper rod will be gradually improved.
