连续铸钢的结晶器振动,是浇注时使铸坯和结晶器壁脱离(俗谓“脱模”)的一个重要手段。依据铸坯在结晶器内受力状态,其脱模机理有三个方面。 1.减小结晶器内阻力的机理 振动使润滑物质潜到钢液面以下,增大和改善了铸坯润滑面积和条件,减少了结晶器内的摩擦与粘结阻力。国内外试验得出振动的结晶器比不振动的结晶器,阻力最大可降低50％。
Continuous casting steel mold vibration, cast slab and crystallizer wall separation (popular so-called “demoulding”) an important means. According to the slab in the mold within the force state, the stripping mechanism has three aspects. 1. The mechanism of reducing the resistance of the mold Vibration makes the lubricating material dive to below the molten steel surface, increases and improves the lubricating area and condition of the billet and reduces the friction and the bonding resistance in the mold. Domestic and foreign experiments have found that the vibration of the mold than the vibration of the mold, the maximum resistance can be reduced by 50%.
