轧辊是耗用量很大的冶金工具,仅我省的每年用量就在6000吨以上。随着钢铁工业的发展,需求量将更大,因此,提高轧辊质量,降低轧辊消耗具有重要意义。 由于铸造轧辊性能良好,制造工艺简单、成本较低,因此在轧辊使用中占有很大比重。目前在我国,铸造轧辊占70％左右。铸造轧辊的质量在很大程度上取决于轧辊材质的改善。 Roll is a large consumption of metallurgical tools, only the amount of annual consumption in our province is more than 6,000 tons. With the development of the steel industry, the demand will be greater, therefore, to improve the roll quality, reduce roll consumption is of great significance. Due to the good performance of the casting roll, the manufacturing process is simple, the cost is low, so the roll uses a large proportion. Currently in our country, casting roller accounted for about 70%. The quality of the casting roll depends largely on the improvement of the material of the roll.
