The roll can achieve and exceed the service life and technical level as America’s D2 and H13, Japan’s SKD11 and SKD61, and Germany’s X155CrVMo121 and X40CrMoV5-1, and it is 2-3 times as long as GCr15, 9Cr2, 9Cr2Mo, 9Cr2MoV roll and is 3 times as long as 3Cr2W8V roll and is two times as long as Cr12 roll. 4. Several specific principles about selecting roll material For selecting roll material for every batch of rolled product the specific principles are as follows. 4.1. First principle for rolled product quality The roll must be to select good material for meeting the requirements of high quality, exact size and exact shape. 4.2. Difficult formed principle considered rolled product thickness, steel grade and product shape Good roll material must be selected to difficult formed and big rolling force condition and this is in security for realisation of cold roll formed and reliable production. 4.3. The principle about big or small rolling batch Big rolling batch must be to select good roll material. 5. Conclusion The manufacturing technology of roll relates to many technical fields and multiple subjects. The roll industry has had great development and progress accompanied by rolling steel technical progress and changed new rolling steel equipment, therefore only by paying close attention and deeply understanding the development trend of iron and steel industry can the roll manufacturer ascertain direction for self- development and progress, and only by close cooperation with the user of rolls in the ways of changed service condition and continuous technological progress can the roll manufacturer stand firm in the fierce competition and make contribution for our country to become the iron and steel power as soon as possible.
