[中文适用范围]： 本文件： ——规定了 3.1 中定义的处理钢水的二次炼钢机械和设备（SSME）的一般安全要求； ——处理与 SSME 有关的所有重大危险、危险情况和事件，按预期使用且在制造商预见的条件下使用，但也包括可预见的误用、故障和故障； ——规定了在设备的设计、预装配、运输、现场装配、调试、操作、维护、退役和拆解过程中应满足的确保人员安全的要求； ——假设 SSME 由经过充分培训且有能力的人员运营和维护。 设置、调整和维护的手动干预被视为设备正常使用的一部分。 本文件适用于在真空或常压下处理钢水工艺的 SSME，涵盖： ——LF、钢包炉、 — VD、真空脱气、 — VOD、真空氧气脱碳、 — RH (OB)、Ruhrstahl Heraeus（氧气）吹炼），— 与工艺相关的接口/交互（例如根据设计、控制）：a) 工艺介质，b) 一次和二次气体净化装置，c) 材料处理系统，d) 钢包转运车，以及 e)起重机和钢包。 注1：由于二次冶金工艺的多样性，除了本文件中讨论的主要工艺外，还有其他变体（例如VODC——真空氧气脱碳转炉、CAS、CAS-OB）。 大多数国家/地区要求实施特定于该设备的适用安全要求。 本文件不涵盖以下设备的安全要求： ——起重机； ——转运车，例如钢包转运车、罐车、维护车； ——叉车或其他运输设备； 1——钢包； ——换衬区域的换衬和预热设备； ——符合 ISO 13577-2 的燃烧器（RH 容器的燃烧器喷枪由 ISO 13577-2 涵盖，但最大主燃烧器点火时间除外，见 5.2.26.2）； ——除尘、排烟系统的清洁和处理； ——工艺介质（如空分、锅炉房、蒸汽发生系统）； ——物料搬运系统。 注2：本文件考虑了由于重型部件的运输/定位（例如通过起重机（例如钢包、容器、盖子））造成的重大危险和危险情况（见5.2.3）。 本文件不适用于中小型企业及在其发布之日之前制造的相关设备。 [外文原描述]： This document: — specifies the general safety requirements for secondary steelmaking machinery and equipment (SSME) as defined in 3.1 to treat liquid steel; — deals with all significant hazards, hazardous situations and events pertinent to SSME, when used as intended and under conditions foreseen by the manufacturer, but also includes foreseeable misuse, faults and malfunctions; — specifies the requirements to ensure the safety of persons which are to be met during the design, pre-assembly, transport, sites assembly, commissioning, operation, maintenance, decommissioning and dismantling/ disassembling of the equipment; — assumes that SSMEs are operated and maintained by adequately trained and competent personnel. Manual intervention for setting, adjustment and maintenance is accepted as part of the normal use of the equipment. This document applies to SSME involved in the treatment process of liquid steel under vacuum or atmospheric pressure and covers: — LF, ladle furnace, — VD, vacuum degassing, — VOD, vacuum oxygen decarburization, — RH (OB), Ruhrstahl Heraeus (oxygen blowing), — process related interfaces/interactions (e.g. according to design, controls) to: a) process media, b) primary and secondary gas cleaning plant, c) material handling systems, d) transfer cars for steel ladle, and e) crane and ladle. NOTE 1 Due to the variety of secondary metallurgical processes, there are other variants (e.g. VODC – vacuum oxygen decarburization converter, CAS, CAS - OB) in addition to the main processes discussed in this document. Most countries require that applicable safety requirements, specific to this equipment be implemented. This document does not cover safety requirements for the following equipment: — cranes; — transfer cars, e.g. ladle transfer cars, tank cars, maintenance cars; — fork lift trucks or other transporting equipment; — ladles; — equipment for relining and preheating in the relining area; — burners according to ISO 13577 ‑ 2 (the burner lances for RH vessels are covered by ISO 13577 ‑ 2 except for maximum main burner ignition time, see 5.2. 26 .2 ); — cleaning and treatment of dust and fume exhaust systems; — process media (e.g. air separation, boiler house, steam generation system); — material handling systems. NOTE 2 Significant hazards and hazardous situations due to transporting/positioning of heavy components, e.g. by cranes (e.g. ladles, vessels, covers) are considered in this document (see 5.2.3 ). This document is not applicable to SSMEs and associated equipment manufactured before the date of its publication.
