我厂铸铁车间生产的轧辊中以冷铸轧辊为主。(同时也生产少量的球墨铸铁轧辊及带槽辊)。因限于设备条件,一般只生产直径500mm以下的轧辊,(或重在2.2吨以下)。由于我厂专门生产各轧钢厂所需轧辊,因此产品品种比较繁杂,每包鉄水得浇铸几种不同规格的轧辊,这样在控制轧辊白口深度上给带来许多困难。过去,我厂的轧辊的质量很差,一方面合格率波动不定,另一方面交货的轧辊用户意见很多,(反映白口浅,白口深度不均匀及开槽后发现气孔等等)。自1954年以来,一方面学习了兄弟厂的先进经验,及贯彻了苏联专家马洛夫提出的#9涂料等建议,另一方面
I cast iron plant production of chilled rolls in the roll-based. (Also producing a small amount of ductile iron rolls and grooved rolls). Due to the limited equipment conditions, the general production of only roll diameter of 500mm (or less than 2.2 tons). As I plant specializing in the production of the rolling mill rolls required, so the product variety is more complicated, each bag of water cast several different specifications of the roll, white roll in the control of the depth to bring many difficulties. In the past, the quality of the rolls in our factory was very poor. On the one hand, the qualified rate fluctuated. On the other hand, there were many opinions from the customers who delivered the rolls. (The results showed that the white mouth was shallow, the depth of white mouth was uneven, and the stoma was found after grooving. Since 1954, on the one hand, he has studied the advanced experience of Brother Factory and implemented the proposal of # 9 paint made by Soviet expert Maloff. On the other hand
