Large ladle crane
Foundry industry crane and Casting hanging Crane
Foundry crane is one of the main equipments in the continuous casting technology of steelmaking. It is mainly used for pouring melted iron from additive bay of converter to converter; Lifting melten steel from refining bay to refining furnace or lifting melten steel from melten steel bay to ladle turret of continuous casting machine.
The overall structure of foundry crane has the following forms: Two girder and two rail, four girder and four rail, and four girder and six rail, etc. The form of two girder and two rail, four girder and four rail, are mainly used for middle and large-tonnage foundry crane; The form of four-girder and six-rail and two trolley is mainly used for extra large-tonnage foundry crane.
