Background
The twin-roll thin strip continuous casting technology is a new technology for directly casting a thin strip with the thickness of 1-5 mm by taking liquid metal as a raw material and taking two casting rolls with opposite rotating directions as crystallizers. Compared with the traditional strip steel production process flow, the strip steel produced by the technology can save equipment such as a continuous casting machine, a heating furnace, a rough rolling unit, a finishing rolling unit and the like, is shortened by 83 percent compared with the traditional production line, saves the production cost, can effectively reduce the exhaust emission, reduces the energy consumption and the environmental pollution, improves the production efficiency and the economic benefit, and accords with the current economic development trend of low carbon and environmental protection.
The process flow of the twin-roll thin strip casting and rolling production process is as follows: liquid metal → casting rolls → rolling mills → ultra-fast cooling → flying shears → coiling. And rolling the cast thin strip by a rolling mill for one frame, and then, cooling the thin strip by ultra-fast cooling to enter a coiling machine for coiling. Because the distance from the outlet of the rolling mill of the thin strip casting and rolling production line to the coiling is only a few meters short, the conventional technologies such as laminar cooling, aerosol cooling and the like can not realize short-time, quick and accurate temperature control.
