PROCESS DESCRIPTION?

? ? Nickel cupronickel strip horizontal continuous casting production process is as follows:

Electrolytic copper to medium frequency melting furnace, composition adjustment to the holding furnace - mold - time cooling, secondary cooling to the dummy machine, shearing machine, coiling machine

Choose raw materials as stipulated in the technology file (electrolytic copper), will join the medium frequency melting furnace smelting raw materials;

? ? To furnace smelting, add a certain thickness of coating agent, and regularly quantitative add raw materials, melting furnace cavity good molten copper water hydraulic dump into the holding furnace cavity, heat preservation of copper liquid temperature in the furnace, automatically control, the copper in the holding furnace casting temperature and keep the water in a certain level of scope, copper under the effect of liquid level, the water flow into the mold, by mold cooling crystallization into strip, copper billet continuous led by the dummy machine, to form the required shape of the slab. Slab at the exit is equipped with temperature measuring device equipped with a secondary cooling system, cooling water flow rate can be adjusted, water temperature, water pressure real-time monitoring, when the water temperature is higher than the set value, the water pressure is lower than the set value when casting machine stop drawing. Using these controls, mainly in order to guarantee the crystallization temperature, the stability of process parameters, to ensure product quality and safety.

? ? The strip is pulled out by tractors, tractor stop and reverse push time is adjustable, should according to different materials, different specifications, the surface quality of the situation, determine the best control parameters and adjust in time, led by PLC program control, implementation cycles, stop, backstepping.

? ? The strip after the dummy machine to send the strip to synchronous cutting machine.
