GB/T 23583.1-2009Molten steel ladles - Part 1: Types and basic parameters (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 1 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. Zhongzhida Qingdao Environmental Protection Equipment Co., smelting, Qingdao Green Environmental Protection Equipment Co., Ltd., Weihai casting machine Mechanical plant, Suzhou Jin-casting plant flowers. The main drafters of this section. GOLD Ting, Ren first, Aviva late, Qin Wei Feng. Ladle of molten steel - Part 1. Types and basic parameters

1 Scope

China's national standard for the types and basic parameters of molten steel ladles. It is Part 1 of GB/T 23583 and specifies the types, the basic parameters and the designation of ladles used to hold and pour molten steel. A ladle is the simplest-looking object in a steelworks and one of the most consequential: a steel shell lined with refractory, carrying up to several hundred tonnes of liquid steel at sixteen hundred degrees, lifted by crane over people and equipment. Its capacity is the unit in which a steelworks is organised - the converter, the ladle, the caster and the crane are all sized to each other - so the ladle capacity is not a free choice but the parameter around which a plant is designed. This part fixes the types and the parameters that make a ladle specifiable. The types divide by how the steel leaves: the lip-pour ladle, tipped to pour over its edge, used for smaller castings; the bottom-pour ladle with a stopper or a slide gate, which is what every continuous caster and every large casting operation uses, because pouring from the bottom leaves the slag floating on top behind instead of washing it into the mould; and by whether the ladle is a simple holding vessel or a treatment vessel with provision for stirring, alloy addition and heating. The parameters are the nominal capacity, the internal dimensions and the shell dimensions, the freeboard, the trunnion position and the total mass empty and full - the last two being what the crane and the plant structure are designed against. Issued on 13 April 2009 and in force since 1 January 2010.

GB/T 23583 provisions of this section and basic parameters of liquid steel ladle. This section applies to metallurgical industry open hearth casting liquid steel furnace and converter using a ladle (hereinafter referred to as a ladle).
