复合半钢轧辊是随着我国轧钢工业的日益发展而出现的铸造轧辊新品种。一、复合工艺的选择:铸造轧辊的复合浇注工艺有多种形式。 1.冲洗浇注复合铸造法:(见图1)。 2.底漏浇注复合铸造法:(见图2)。 3.离心浇注复合铸造法:(见图3)。 4.隔套浇注复合铸造法:(见图4) 在轧辊辊身型腔里,放置一个不同厚度的钢板隔套,同时进行内、外层不同成分的钢水的浇注,当浇到隔套上平面时,停止外层钢水的浇注,继续进行芯 Composite semi-steel roller is with the growing development of China’s steel rolling industry emerged a new variety of casting roller. First, the choice of composite process: Foundry roll compound casting process has many forms. 1. Flush casting casting method: (see Figure 1). 2. At the end of pouring cast casting method: (see Figure 2). 3. centrifugal casting compound casting method: (see Figure 3). 4. The spacer casting compound casting method: (see Figure 4) In the roller body cavity, placed a different thickness of the steel spacer, while the inner and outer layers of molten steel pouring, when poured into the spacer Plane, stop casting outer molten steel, continue to core
