17、 (E) 4 European foreword This document (EN 16774:2016) has been prepared by Technical Committee CEN/TC 322 “Equipments for making and shaping of metals - Safety requirements”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by
18、publication of an identical text or by endorsement, at the latest by October 2016, and conflicting national standards shall be withdrawn at the latest by October 2016. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CEN
19、ELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directiv

25、roduction This European Standard is a type C standard as stated in EN ISO 12100. The machines and equipment concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this standard. This document assumes that the converter plant is operated a
26、nd maintained by adequately trained and competent personnel (see 7.5); manual intervention for setting, adjustment and maintenance is accepted as part of the intended use of the plant; the plant is used with adequate workplace lighting conforming to EN 12464-1. This document assumes that the input m
27、aterials do not contain the following hazardous components: radioactive scrap; explosives; entrapped water/ice; closed containers; oversized scrap which can lead to water leakage due to collision with lances (see 7.3.5). The charging should be done to avoid/minimize risk of explosion. When requireme
28、nts of this type-C standard are different from those which are stated in type-A or type-B standards, the requirements of this type-C standard take precedence over the requirements of the other standards for machines that have been designed and built according to the requirements of this type-C stand
29、ard. BS EN 16774:2016EN 16774:2016 (E) 6 1 Scope This European Standard applies for steel converter and its associated equipment (hereinafter referred to as converter plant) used in the process of carbon or stainless steel making as defined in 3.1 and illustrated in Annex B. This European Standard d
30、eals with significant hazards, hazardous situations and events relevant to the converter plant. It covers the intended use and foreseeable misuse. This European Standard specifies the safety requirements to be met during transport, assembly, commissioning, operation, maintenance (as described in Cla
31、use 5) and decommissioning/disassembly of the equipment. This European Standard applies to: Steel converter and its associated equipment for the oxygen steelmaking process from hot metal/liquid steel and scrap charging; via oxygen refining and stirring; temperature measurement and sampling equipment
32、; up to tapping including slag retaining device; cooling systems; maintenance devices (e.g. relining device, tap hole repair device); process related interfaces/interactions (e.g. according to design, controls) to media, primary and secondary gas cleaning plant, material feeding systems and ladle al
33、loying systems, transfer cars for steel ladle and slag pot, and charging/tapping equipment, e.g. crane, scrap chute, ladles and slag pots. This European Standard does not cover safety requirements for: usage of process media other than oxygen, nitrogen, argon and compressed air; primary and secondar
34、y gas cleaning plants; measuring devices with radioactive sources; material feeding systems and ladle alloying systems; transfer cars for steel ladle and slag pot; charging/tapping and de-slagging equipment, e.g. crane, scrap chutes, ladles and slag pots; auxiliary winches and hoists. BS EN 16774:20
35、16EN 16774:2016 (E) 7 NOTE 1 For variations of converter process where other gases and media, e.g. hydrocarbons, fuels, steam, etc. are used, additional safety measures have to be considered which are not covered in this safety standard This European Standard is not applicable to converter plant, ma
36、nufactured before the date of publication of this standard in the Official Journal (OJ). NOTE 2 In case of revamping, this European Standard can be used as a guideline for the specific parts to be revamped. 2 Normative references The following documents, in whole or in part, are normatively referenc
