鋼管及冷彎型鋼用新型高鉻合金鑄造軋輥的節(jié)能節(jié)材研究

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

摘要: 介紹了鋼管及冷彎型鋼用軋輥在國內(nèi)外的生產(chǎn)和發(fā)展概況,以及國內(nèi)自主研發(fā)并制造的新型高鉻合金鑄造軋輥的情況。將新型高鉻合金鑄造軋輥與國內(nèi)外先進水平的鍛造軋輥進行了對比,包括使用性能、使用壽命和節(jié)能節(jié)材效果等方面;對比結(jié)果證明,新型鑄造軋輥的材質(zhì)和工藝與現(xiàn)有同類產(chǎn)品完全不同,其在滿足先進生產(chǎn)機組和高級別合金鋼管生產(chǎn)要求的同時,還具有明顯的節(jié)能節(jié)材效果。

Abstract: 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.
