SUMMARY:Multifunctional tundish with using electromagnetic actions on melt at continious casting of steel
DESCRIPTION:The PTIMA NASU proposed new concept of continuous casting of steel for small metallurgical plants. The idea is both reducing capital costs and amount of equipments. This is achieved by excluding “ladle-furnace” aggregate from technology, reducing number of metal overflows, performing in tundish the finishing liquid steel on temperature & chemical composition, and cleaning from non-metallics.
As such multifunctional tundish, it is proposed a pilot magnetodynamic (MD) mixer-batcher for cast iron and steel, developed at the PTIMA NASU. This aggregate uses electromagnetic energy for melt heating, stirring and pouring, and constructively combines functions of induction channel furnace and electromagnetic pump. Such tundish, depending on steel grades produced, process productivity and design of continuous casting machine (CCM), can have one or two chambers, induction channels with inductors, electromagnetic devices for metal stirring and pouring, and also it can be additionally equipped with submersible plasmatron for melt refining.
The proposed MD-tundish has following advantages: - adjustable induction heating and electromagnetic stirring of melt; - controlled low-pressure electromagnetic pouring of melt with possibility of distributing and stabilizing flow over the width of CCM mold; - possibility for periodic stop/restart at manufacturing small batches of cast ingots with various sections and from different steel grades; - reduction of metal losses and increasing metal yield; - increasing CCM work stability and productivity; - reduction of refractories’ consumption; - energy saving due to rational modes of melt heating and stirring; - exclusion of using special expensive systems for braking steel flows in CCM mold; - improving quality of cast ingots’ surface due to prevention of their cracking and swelling; - reducing porosity and number of non-metallics; - reducing risk of melt breakthroughs; - improvement of working conditions for personnel and ecology due to use of electrical energy, reduction of thermal radiation and harmful emissions.
