After the molten steel produced by the converter is refined by the refining furnace, the molten steel needs to be cast into billets of different types and specifications. Continuous casting section is the process of continuous casting the refined molten steel into billets. The main equipment includes rotary table, tundish, mold, tension leveller and so on.
The non-sinusoidal vibration technology of crystallizer has significant effect on improving the casting speed, improving the surface quality of casting billet and reducing the rate of leakage. This technology can not only improve the casting speed, increase productivity, reduce tension leakage, make the continuous casting machine production stable, but also can provide high surface quality billet for rolling, improve the quality of rolling material.
The ladle containing refined steel is transported to the rotary table, which is rotated to the pouring station, and the steel is injected into the tundish, which is then distributed to each mold by the nozzle. Mold is one of the core equipment of the continuous casting machine, which makes the casting form and solidify rapidly. The tension straightening machine and the crystal vibration device work together to pull the casting out of the mold, after cooling, electromagnetic stirring, cutting into a certain length of slab.
Automatic control of continuous casting mainly includes speed control of casting roller, frequency control of mould vibration, fixed-length cutting control and other control technologies. Continuous casting and rolling requires continuous casting machine to be able to produce blank at high temperature, casting blank has high surface quality and internal quality, at the same time, continuous casting machine is required to have stable high productivity, high casting speed, in order to meet the needs of high-speed rolling. Non-sinusoidal vibration technology of mould is the key technology of continuous casting and rolling.
