6、kseinrichtungen. Representatives of manufacturers and users of steel converters, and of the employers liability insurance associations contributed to this standard. This standard contains specifications giving detail to the essential requirements set out in Annex I of the “Machinery Directive”, Dire
7、ctive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the European Union
8、, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in Clause 2 and in the Bibliography of the EN have been published as the cor

DIN EN 16774:2016-12 EN 16774:2016 (E) 5 Introduction 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, hazardou
31、s situations and events are covered are indicated in the scope of this standard. This document assumes that the converter plant is operated and maintained by adequately trained and competent personnel (see 7.5); manual intervention for setting, adjustment and maintenance is accepted as part of the i
32、ntended use of the plant; the plant is used with adequate workplace lighting conforming to EN 12464-1. This document assumes that the input materials do not contain the following hazardous components: radioactive scrap; explosives; entrapped water/ice; closed containers; oversized scrap which can le
33、ad to water leakage due to collision with lances (see 7.3.5). The charging should be done to avoid/minimize risk of explosion. When requirements 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 o
34、ver the requirements of the other standards for machines that have been designed and built according to the requirements of this type-C standard. DIN EN 16774:2016-12 EN 16774:2016 (E) 6 1 Scope This European Standard applies for steel converter and its associated equipment (hereinafter referred to
35、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 deals with significant hazards, hazardous situations and events relevant to the converter plant. It covers the intended use and foreseeable misuse. This Eu
36、ropean Standard specifies the safety requirements to be met during transport, assembly, commissioning, operation, maintenance (as described in Clause 5) and decommissioning/disassembly of the equipment. This European Standard applies to: Steel converter and its associated equipment for the oxygen st
37、eelmaking process from hot metal/liquid steel and scrap charging; via oxygen refining and stirring; temperature measurement and sampling equipment; up to tapping including slag retaining device; cooling systems; maintenance devices (e.g. relining device, tap hole repair device); process related inte
38、rfaces/interactions (e.g. according to design, controls) to media, primary and secondary gas cleaning plant, material feeding systems and ladle alloying systems, transfer cars for steel ladle and slag pot, and charging/tapping equipment, e.g. crane, scrap chute, ladles and slag pots. This European S
39、tandard does not cover safety requirements for: usage of process media other than oxygen, nitrogen, argon and compressed air; primary and secondary gas cleaning plants; measuring devices with radioactive sources; material feeding systems and ladle alloying systems; transfer cars for steel ladle and
40、slag pot; charging/tapping and de-slagging equipment, e.g. crane, scrap chutes, ladles and slag pots; auxiliary winches and hoists. DIN EN 16774:2016-12 EN 16774:2016 (E) 7 NOTE 1 For variations of converter process where other gases and media, e.g. hydrocarbons, fuels, steam, etc. are used, additio
41、nal safety measures have to be considered which are not covered in this safety standard This European Standard is not applicable to converter plant, manufactured before the date of publication of this standard in the Official Journal (OJ). NOTE 2 In case of revamping, this European Standard can be u
42、sed as a guideline for the specific parts to be revamped. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
