随着轧钢事业的迅速发展轧辊的生产远远不能满足实际的需要,在以铁代钢以铸代锻的口号下我国轧辊生产者已大胆地铸造了φ1150mm的球墨铸铁轧辊代替钢轧辊在初轧开坯机架上得到了成功的应用从而为我国轧辊生产开辟了广阔的前途。 但是目前要求高强度高高硬度的冷轧薄板轧辊仍然采用若合金锻钢轧辊:这种轧辊需要经过一系列的热处理过程,生产周期很长,成本很高,因此大胆地以合金球墨铸铁轧 With the rapid development of rolling business roller production far can not meet the actual needs of the iron and steel to replace the slogan of cast forging under the slogan of our country has bold cast cast iron ductile iron φ1150mm instead of steel roll in the initial rolling Billet rack has been successfully applied to the roll production in our country has opened up a vast future. However, the current requirements of high strength and high hardness of the cold rolled sheet roll is still used if the alloy forging roll: This roll through a series of heat treatment process, the production cycle is very long, high cost, so bold to alloy ductile iron rolling
