The roller electromagnetic stirring is applied in continuous casting of steel to improve steel quality and production.
The in-roll electromagnetic stirrer with high thrust force for the secondary cooling zone of slab has passed the
scientific and technological achievements appraisal of China Metal Society, as the technology of it is advanced.
The product has been applied on more than one hundred strand of continuous casting line for slab, and its
market share in China is over 90%;
It is easy to install. The in-roll electromagnetic stirrer is installed on the segment of the continuous casting
machine, replacing free supporting roller, without affecting the structure of the existing continuous casting
machine. The installation dimensions are exactly the same as that of the ordinary roller, and can be exchanged.
The position is easy to be adjusted;
lt adopts special magnetism shielding technology, non-cogging structure technology, numerical simulation
optimization of winding and iron core structure technology, the electromagnetic force is above twice that of
similar products (patented invention);
The roller sleeve is made of non-magnetic, high-Cr-Ni heat-resistant stainless steel, which has excellent wear
resistance and heat resistance; And its reasonable water circuit design provides high cooling efficiency;
The auxiliary supporting structure is adopted to be applied on continuous caster with plate width of 1800 mm to
2600 mm; and the splitting design is adopted, so as to make it applied on continuous caster with plate width of
2600 mm or more.
