Ⅱ.Process:
Burdening (Returns should be baled) → Smelting furnace → Chemical analysis → Heating up the sealed launder → Crystallizer → Primary cooling → Secondary cooling → Withdrawal machine → Shearing machine →Coiler

Select the raw materials according to process document, determine the feeding procedure according to melting points of metallic elements, furnace burden proportions, and difficulty of oxidation burning losses, and charge the raw material into the smelting furnace; When smelting, add certain thickness of covering agent into the furnace, which shall be supplemented in-time; When the molten copper inside the furnace reaches tapping temperature, lab-test the composition of molten copper inside the furnace; Before tapping, completely clean out the clinkers in molten copper; After the tapping of each furnace, keep around 800 kg molten copper inside the furnace, as the starting block. Transfer the molten copper (molten and well-adjusted in the melting chamber) through the sealed launder into the holding furnace, control the temperature of molten copper, keep the molten copper inside the holding furnace at the casting temperature and at certain level range. Under the action of level, the molten copper flows into the crystallizer, and get crystallized into plate-type copper billet through primary cooling by crystallizer. Under the continuous drawing by withdrawal machine, the plate billet of required shape is formed. Secondary cooling system is installed at plate billet outlet, and the flow rate of cooling water is adjustable. The main purpose for adopting these control measures is to ensure crystallization temperature as well as stabilization of process parameters, so as to ensure product quality. The withdrawal of strip billet is realized by means of the dragger, and the time of drawing, stop and reverse pushing by the dragger is continuously adjustable. The optimal control parameter should be determined and timely adjusted according to different materials, different specifications and surface quality conditions. The drawing is controlled by PLC program, realizing cyclical actions of drawing, stop, and reverse pushing.
