Improve fluid of stainless steel steel clean spent center wraps new mastery of a skill or technique to include: Steel bag wraps the languid lazy gas of crystallizer to safeguard mould to central bag, center, pericardium blows argon to finish mould of languid lazy atmosphere in, central Bao Mi is sealed or vacuum mould; Steel bag, center package falls broken bits to detect, pericardium is chosen in prevent eddy current technical ability; Steel bag is full automatic irrigate and immersion leaves irrigate skill; Pericardium is applied in block wall, dam, block to flow implement hold dominate molten steel activity, apply filter, electromagnetism to rotate centrifugal implement or the bottom blows argon to cut down mingle, apply tall alkalinity to mask an agent to absorb mingle, build broken bits of the pericardium in reproducibility, apply alkalescent be able to bear or endure material drops corrode, choose H model or the pericardium in high capacity; Pericardium heats in hold accuse temperature to shake.
