Industrial furnaces and associated processing equipment - Safety requirements for steel converter and associated equipment (ISO/DIS 23495:2019)

8. Scope
This document applies for new 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 document deals with significant hazards, hazardous situations and events relevant to the converter plant. It covers the intended use and foreseeable misuse.
This document specifies the safety requirements to be met during design, transport, setting up/installation, assembly, commissioning, operation, maintenance (as described in Clause 5) and decommissioning/dis¬assembly of the equipment.
NOTE 1   Assembly does not include erection because national regulations, e.g., national civil engineering laws and regulations or occupational health and safety regulations have to be considered.
This document applies to:
Steel converter and its associated equipment (see Annex B, Figure B.1) for the oxygen steelmaking process
   from charging hot metal/liquid steel and scrap;
   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, device for cleaning the converter mouth);
   process related interfaces/interactions (e.g., according to design, controls) to
o   process media,
o   primary and secondary gas cleaning plant,
o   material feeding systems and ladle alloying systems,
o   transfer cars for steel ladle and slag pot, and
o   charging/tapping equipment, e.g., crane, scrap chute, ladles and slag pots.
This document 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 slag pot;
   charging/tapping and de-slagging equipment, e.g., crane, scrap chutes, ladles and slag pots;
   auxiliary winches and hoists.
NOTE 2   For variations of converter process where other gases and process media, e.g., hydrocarbons, fuels, steam, etc. are used, additional safety measures have to be considered which are not covered in this safety standard.
NOTE 3   In case of revamping, this document can be used as a guideline for the specific parts to be revamped.

Sicherheit von Maschinen - Sicherheitsanforderungen an Stahlkonverter und zugehörige Einrichtungen (ISO/DIS 23495:2019)

Dieses Dokument gilt für neue Stahlkonverter und zugehörige Einrichtungen (nachfolgend als Konverteranlage bezeichnet), die bei der Herstellung von Kohlenstoffstahl oder nichtrostendem Stahl eingesetzt werden, wie in 3.1 definiert und in Anhang B illustriert.
Dieses Dokument behandelt die für die Konverteranlage zutreffenden signifikanten Gefährdungen, Gefährdungssituationen und -ereignisse. Die Norm deckt die bestimmungsgemäße Verwendung und eine vorhersehbare Fehlanwendung ab.
Dieses Dokument beschreibt die Anforderungen zur Sicherstellung der Sicherheit von Personen, die bei Konstruktion, Transport, Aufbau/Installation, Montage, Inbetriebnahme, Betrieb, Instandhaltung (siehe Abschnitt 5) und Außerbetriebnahme/Demontage der Anlage zu berücksichtigen sind.
ANMERKUNG 1   Montage beinhaltet nicht den Aufbau, da nationale Vorschriften, z. B. Nationale Gesetze und Vorschriften zum Bauwesen oder Gesundheits  und Sicherheitsvorschriften, beachtet werden müssen.
Dieses Dokument gilt für:
Stahlkonverter und zugehörige Einrichtungen (siehe Anhang B, Bild B.1) für das Sauerstoffblasverfahren:
—   von der Beschickung mit flüssigem Roheisen/Stahl und Schrott;
—   über Sauerstofffrischen und Spülen;
—   Temperaturmessung und Probenahmegeräte;
—   bis zum Abstich, einschließlich Schlackenrückhaltevorrichtungen;
—   Kühlsysteme;
—   Instandhaltungseinrichtungen (z. B. Ausmauerungsvorrichtung, Abstichloch-Reparatureinrichtung, Einrichtung für die Reinigung der Konvertermündung);
—   prozessbezogene Schnittstellen/Wechselwirkungen (z. B. auf Konstruktion und Steuerungen bezogen) zu:
—   Prozessmedien;
—   primären und sekundären Gasreinigungsanlagen;
—   Materialhandhabungssystemen und Pfannenzuschlagstoffsystem;
—   Transportwagen für Stahlpfannen und Schlackenkübel; und
—   Beschickungs-/Absticheinrichtungen, z. B. Krane, Schrottschurre, Pfannen und Schlackenkübel.
Dieses Dokument behandelt keine Sicherheitsanforderungen für:
—   die Verwendung anderer Prozessmedien als Sauerstoff, Stickstoff, Argon und Druckluft;
—   primäre und sekundäre Gasreinigungsanlagen;
—   Messeinrichtungen mit radioaktiven Quellen;
—   Materialhandhabungssysteme und Pfannenzuschlagstoffsysteme;
—   Transportwagen für Stahlpfannen und Schlackenkübel;
—   Beschickung/Abstich und Abschlackeinrichtungen, z. B. Krane, Schrottrutschen, Pfannen und Schlackenkübel;
—   Hilfs-Winden und -Hebevorrichtungen.
ANMERKUNG 2   Für Änderungen des Konverterprozesses, bei denen andere Gase und Prozessmedien, z. B. Kohlenwasserstoffe, Brennstoffe, Dampf usw., verwendet werden, müssen zusätzliche Sicherheitsmaßnahmen berücksichtigt werden, die nicht von dieser Sicherheitsnorm behandelt werden.
ANMERKUNG 3   Bei Modernisierungen kann diese Europäische Norm als Leitfaden für die zu modernisierenden Teile angewendet werden.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria nee
