GB/T 23583.2-2009Molten steel ladles - Part 2: Technical requirements (English PDF)

Foreword

GB/T 23583 "liquid steel ladle" is divided into two parts.

--- Part 1. Types and basic parameters;

--- Part 2. Technical requirements. This is Part 2 GB/T 23583 of. This part is proposed by China Machinery Industry Federation. This part of the National Foundry Machinery Standardization Technical Committee (SAC/TC186) centralized. This section is drafted. Qingdao Green Environmental Protection Equipment Co., Ltd., Qingdao Zhongzhida Environmental Protection Equipment Co., smelting, casting machine Weihai Mechanical plant, Suzhou Jin-casting plant flowers. The main drafters of this section. Ronny first, gold segment very, Aviva late, Qin Wei Feng. Liquid steel ladle Part 2. Technical requirements

1 Scope

China's national technical requirements for molten steel ladles. It is Part 2 of GB/T 23583 and specifies the requirements, the test methods, the inspection rules and the marking, packaging, transport and storage for ladles used to hold and pour molten steel. Where Part 1 says what a ladle is, this part says what it must be, and every requirement in it derives from one fact: the consequence of a ladle failing is a breakout of liquid steel, which kills people and destroys the plant beneath it. So the shell is treated as a lifted structural component rather than a container. Its plate material, thickness and welding are specified, the welds are examined, and the trunnions and their attachment - the single point through which the entire load passes into the crane - carry the strictest requirements in the document, with a defined safety factor and mandatory examination. The shell must also tolerate the thermal condition it works in: the outside of a ladle in service runs at several hundred degrees, the shell expands against a rigid refractory lining, and the distortion that results is what eventually cracks a ladle. The lining is the other half. Its design and installation, the safety lining behind the working lining, and the criterion for taking a ladle out of service are specified, because a lining worn beyond its limit is exactly how a breakout happens. Around those sit the slide gate or stopper mechanism and its operation, the preheating requirement - charging steel into a cold ladle cracks the lining and chills the metal - the lifting and tilting arrangements, and the inspection regime over the ladle's life. Issued on 13 April 2009 and in force since 1 January 2010.

GB/T 23583 provisions of this part of the molten steel ladle technical requirements, test methods, inspection rules and warranty periods of time. This section applies to metallurgical industry open hearth casting liquid steel furnace and converter using a ladle (hereinafter referred to as a ladle).
