Champ d’application

This standard applies to the design, manufacturing, and usage safety requirements of molten steel ladles utilized in steelmaking and casting production. It covers the specific equipment used in these heavy industrial environments. This standard is mandatory for all manufacturers producing or supplying molten steel ladles in the Chinese market. It does not apply to other types of metal melting or handling equipment, focusing exclusively on molten steel ladles.

Exigences techniques

The standard specifies comprehensive safety requirements addressing mechanical, electrical, thermal, and other associated hazards. For mechanical safety, it outlines material specifications for critical structural components (such as the barrel body, lifting lugs, and trunnions) and mandates specific design safety factors (e.g., a factor of 10 for lifting lugs and 5 for crossbeams). Manufacturers must ensure the ladle features a reliable self-locking mechanism and can withstand at least 2 times the rated load without abnormal phenomena. Regarding electrical safety, the standard requires compliance with GB 5226.1 and mandates proper thermal insulation and reliable fixation of cables to prevent electric shock and unexpected movements. For thermal safety, the standard requires the use of personal protective equipment, specific clearance heights for the molten metal surface, and strict prohibitions against using ladles with cracked linings. It is strictly forbidden to cool the hot ladle with water to prevent explosion hazards.

Méthodes d’essai

Compliance is verified through four primary judgment methods. Functional testing is used to check if safety functions meet requirements under operational conditions. Testing involves using measuring instruments to check specific parameters against standardized methods. Calculation or drawing inspection is applied to analyze aspects like stability, center of gravity, and mechanical strength. Finally, Observation relies on visual inspection of specified components and usage information. If multiple methods are used, their results must be consistent to demonstrate compliance.
