| | Some proved measures to reduce temperature loss of intermediate billet produced by conventional hot strip rolling mill were introduced.Meanwhile,their technique characteristics and choose principle were analyzed. | | 介绍了世界范围内现代化常规热轧带钢生产中中间坯保温方面的成熟技术,并分析了其技术特点和选择这些技术应遵循的原则。 | | 文摘来源 | | The new 2250 hot strip mill of Tisco.aims at producing wide and thin gauge stainless steel strip.To meet the needs of producing stainless steel,the means of transfer bar heat shield is one of the key issues in the production line.Four means of transfer bar heat shield used in conventional stainless steel hot strip mill at present are discussed.The ciolbox with edge heat shield is believed to be a better solution,With a space kept free to install a edge heater in future in the layout. | | 太钢新建2250热连轧机定位于宽、薄不锈钢规格的生产,鉴于热轧不锈钢生产的特点,中间坯的保温方式成为整条生产线的关键环节之一。对目前传统热连轧不锈钢生产线采用的四种保温方式进行对比,认为采用带端部隔热板的热卷箱同时预留边部加热器的方案是较佳选择。 | | 文摘来源 | | >=Along with the process of our industrialization more emphasis have been put on the quality and the widening of the hot rolled strip products, How to produce high value added products is becoming the focus of the con ventional hot strip mill. The main typical high value added products for conventional hot strip mill are silicon steel (HiB、GO、NGO),stainless steel (austenite,martensite and ferrotite),pipeline steel (up to X80) and high strength steel (up to 1200MPa). All those products require temperature an... | | 随着我国工业化进程的加快,市场对热带钢轧机的产品质量要求日益提高,热轧品种范围日益扩大。高附加值产品的生产比将成为常规热轧带钢轧机产品的主要立足点。目前常规热轧带钢轧机的主要高附加值产品包括硅钢(HiB、GO、NGO)、不锈钢(200-400系列)、管线钢(X80)、高强度钢(1200 MPa以上),供冷轧原料。这些高附加值产品的生产对热轧产品的温度控制和尺寸精度控制都提出了更高的要求。针对温度敏感性强的产品(如硅钢、不锈钢、镀锡原板、IF原板、DP、MP、Trip等)等产品的生产,克服中间坯温降的问题日益突出,采用何种方式减少中间坯的温差是每个生产厂都十分关心和必须解决的问题。本文介绍了世界范围内现代化常规热轧在中间坯保温方面的成熟技术并分析了这些技术的特点和选择这些技术所应遵循的原则。 | | 文摘来源 | |   |
