钢管及冷弯型钢用新型高铬合金铸造轧辊的节能节材研究

介绍了钢管及冷弯型钢用轧辊在国内外的生产和发展概况,以及国内自主研发并制造的新型高铬合金铸造轧辊的情况.将新型高铬合金铸造轧辊与国内外先进水平的锻造轧辊进行了对比,包括使用性能、使用寿命和节能节材效果等方面;对比结果证明,新型铸造轧辊的材质和工艺与现有同类产品完全不同,其在满足先进生产机组和高级别合金钢管生产要求的同时,还具有明显的节能节材效果.

Study on Energy and Material-saving for Making of New Type High Chromium Alloy Cast Roll Used for Producing Steel Tube and Cold-bended Section Steel

Described here in the article are the pro duct ion and development situations of rolls as used for producing steel tube and cold-bended section steel both at home and abroad. Also elaborated is the new type high chromium alloy cast roll as developed and manufactured independently by domestic technical force. Moreover the said new type roll is compared with the advanced forged rolls as made at home and abroad in term of performance, service span and energy and material-saving effectiveness. The comparison result shows that material and process of the new type roll is completely different from the those of the similar products, and that the new material is not only capable of meeting requirements for relevant advanced pipe mills, and production of high grade alloy steel pipes, but also bring about high energy and material-saving effectiveness.
