据苏刊报道,为了获得优质挤压铸造的铸钢件,试验研究了一种改进的挤压铸造法。在挤压铸造时,借助压型中锒衬玻璃壳的软化将压力机单向压力转化为各向压力,压向压型内正在结晶韵钢水。这种各向压力足以消除铸件内的缩孔,压型型膣被加热的温度也因有玻璃壳而比用一般涂料时为低,同时因钢水不与压型壁直接接触,从而可以提高压型的寿命。
According to Su-Jun reported that in order to obtain high-quality squeeze cast steel casting, the pilot study of an improved squeeze casting method. In the squeeze casting, with the help of pressure in the glass lining to soften the uniaxial press into one-way pressure, the pressure is within the pressure-type crystal rhyme steel. This is enough pressure to eliminate the shrinkage of the castings, the pressure type 膣 is also heated because of the temperature of the glass shell is lower than the average coating, at the same time because the molten steel is not in direct contact with the pressure wall, which can improve the pressure Type of life.
