In the metallurgical and melting fields, a ladle is a vessel used to transport high temperature metal or pour out molten metals. Usually it has three different types, for example, casting ladle, transfer ladle, treatment ladle. Ladles are normally rated by their working capacity rather than by their physical size. Casting ladle: a ladle used to pour molten metal into moulds to produce the casting. Transfer ladle: a ladle used to transfer a large amount of molten metal from one process to another. Typically a transfer ladle will be used to transfer molten metal from a primary melting furnace to either an holding furnace or an auto-pour unit. Treatment ladle: a ladle used for a process to take place within the ladle to change some aspect of the molten metal. A typical example being to convert cast iron to ductile iron by the addition of various elements into the ladle.
We CSM ladles are made from Cast Steel, which is similar to the following standards, we will offer the material specification as you required.
Standard Specifications for Cast Steel
ASTM A 27
1. Wooden pattern Production
4. First cleaning
5. Heat treatment – grinding (inspection)
6. Rough machining (inspection)-finishing machining (inspection)
The fabrication route is governed by the provisions of the implemented Quality System ISO 9001: 2000. The standard documentation ensures the full traceability of every process step:
• Manufacturer test certificates according to DIN EN 10.204 § 3.1 including chemical composition, mechanical properties and non-destructive examination;
• Dimensional check supported with a “as-built“ sketch;
• Record of the heat treatment chart
