Cold rolled silicon steel continuous decarburization annealing line (CNGO)

I-degrease ang ibabaw ng cold-rolled non-oriented silicon steel (CNGO), at magsagawa ng decarburization annealing at recrystallization annealing sa isang proteksiyon na kapaligiran upang mabawasan ang carbon content ng strip sa tinukoy na hanay, upang ang mga butil ng kristal ay lumaki at ang mapapabuti ang magnetic level, mapawi ang stress at ilapat ang insulation layer.
