| 1. | Rail and - structural steel mill 轨梁轧机 |
| 2. | Second , identifying the disadvantages in technology and equipment compared with the advanced foreign countries . the infrastructure needs to be improved 第二:轨梁厂的技术、设备与国外先进水平比较还有差距,质量控制的基础条件有待提高。 |
| 3. | This paper is a thesis about the application of htac technology on furnace and introduces the furnace construction , regenerative combustion system and control system 摘要介绍了高温空气燃烧技术在攀钢轨梁厂加热炉上的应用,介绍了炉体结构、蓄热式燃烧系统、控制系统及改造后的效果。 |
| 4. | Taking the heating requirement on high speed rail to be produced in pangang into the consideration , this paper discusses the application of field bus fuzzy control system in heating furnace combustion control in pangang ’ s rail & beam plant 本文结合攀钢生产高速铁路用钢轨的加热要求,研究现场总线模糊控制系统在攀钢轨梁加热炉燃烧控制系统中的应用。 |
| 5. | Then , from my experience and my knowledge , the paper offers four improvement countermeasure : first , changing the present certificate to accord with the standard iso9000 : 2000 , recon structuring and improving its quality control level based on the idea of process control 第一:轨梁厂的质量管理体系的应按iso9000 : 2000版的标准及时完成换证工作,用过程控制的思想对现行的质量控制方法进行改进和再造。 |
| 6. | In order to be more typical and practical , the theses pays more attention to analyzing the quality control of the rail - girder factory of panzhihua steel - iron company . the factory is a highly automatic and mechanized heavy rolling mill . it has been practicing a relatively effective quality control for about 20 years 为使文章更具代表性和实用性,本文着重分析了攀钢轨梁厂的质量控制,攀钢轨梁厂作为一家机械化、自动化程度较高的大型轧钢厂其质量控制工作已经开展了20多年,应该说是比较成熟的。 |
| 7. | Abstract : heating curves of billet for heavy rail in reheating furnace are measured by use of dragging coupling methods . effects of fuel consumption , furnace temperature and heating time on billet temperature are studied and current thermal schedule of reheating furnace is evaluated , which provides the basis for optimizing and improving thermal schedule of reheating furnace 文摘:运用拖偶法测量了重轨钢坯在轨梁加热炉内的升温曲线,分析了燃料消耗、炉温与加热时间对钢坯温度的影响,评价了现行的加热炉热工制度,为优化、完善加热炉热工制度提供了依据。 |
| 8. | In order to adjust structure of production 、 meet requirement of market and improve economic benefit 、 cancel old mould casting system , pangang decided to enlarge continuous casting ratio and eliminate mould casting system , pangang decided to install one new bloom casting machine 、 one new 130t lf plants 、 one new 130t rh degassing plants 。 this rh can treat 1000000t molten steel in every year , it meet mostly request of the rail mill that they produce high quality and high speed heavy rail 。 the writer is a stuff member of this project 攀钢公司为了改善产品结构、增强市场竟争能力和提高经济效益,淘汰落后模铸系统,决定扩大连铸比并淘汰模铸,新建一台六流方坯连铸机、一台rh真空处理精炼装置、一座lf炉。这台新建rh真空处理装置年处理钢水100万吨,主要满足轨梁厂生产优质高速重轨和型钢的要求。作者作为该项目的三电部分主要参与人。 |
