我厂专业生产各种冷硬铸铁轧辊,以往采用垂直浇注工艺,白口层很难控制,且易产生砂眼、气孔、夹杂、疏松等缺陷,轧辊的强度也不易保证。近几年来进行了复合离心浇注的试验,经过多次摸索,终于获得成功,于1962年开始成批投产。现将初步经验介绍如下: I plant specializing in the production of various chilled cast iron roll, the vertical casting process used in the past, the white layer is difficult to control, and easy to produce trachoma, porosity, inclusions, loose and other defects, the strength of the roll is not easy to guarantee. In recent years, the composite centrifugal casting test, after many exploration, and finally succeeded, began mass production in 1962. The preliminary experience is introduced as follows:
