And Control

Features and control methods in processes of unstable continuous casting of the 4th department of general steelmaking factory of WISCO were introduced, including ladle free-opening, tundish auto-casting, liquid level control and submerged nozzle’s quick replacing of mould, slag detection of ladle and so on. Countermeasures including updating facilities, improving accurate of controlling system, developing new technology were proved to be effective in practice, they can minimize the bad effect of the unsteady state to the producing stability and slab quality.

Immersion Nozzle

Swirling flow in an immersion nozzle is effective on improving quality of casting block and casting speed in continuous casting process of steel. However, a refractory swirl blade installed in the nozzle is liable to cause clogging, which limit the application of the process. In this study a new process is proposed, that is a rotating electromagnetic field is set up around an immersion nozzle to induce a swirling flow in it by Lorentz force. New types of swirling flow electromagnetic generator are proposed and the effects of the structure of the generator, the coil current intensity and frequency on the magnetic field and on the flow field in the immersion nozzle are numerically analyzed.
