YZ Steel Mill Foundry Crane

Description

YZ Steel Mill Foundry Crane, also known as steel mill ladle crane, is an important lifting and transportation equipment in steel mill smelting workshop. The crane is mainly used for the transfer of liquid metal, pouring and molten iron in the continuous casting process of steelmaking, including the transfer of molten iron to the converter across the converter charging, as well as the lifting of molten steel to the refining furnace across the refining span, or the lifting of molten steel to the continuous casting rotary ladle across the molten steel span.

The structural design of YZ type metallurgical casting crane is divided into various forms according to the tonnage and application requirements, mainly including double girder and double rail, four girders and four rails and four girders and six rails and other types. Among them, double girder double rail and four girder four rail structure is usually applicable to medium and large tonnage cranes, while four girder six rail double trolley form is mainly used for larger tonnage cranes. 125 tons of cranes are usually used in the YZ-type double girder structure, while more than 125 tons of cranes are mostly used in the YZS-type four girder structure in order to meet the demand for higher load bearing.

Structure Design Features

Dafang metallurgical foundry cranes are divided into two types: YZ type and YZS type. The two are significantly different in structural design to meet the needs of different working conditions. YZ type adopts double girder and single trolley structure, which is mainly composed of bridge, trolley, hook beam, trolley running mechanism and electrical system. The main hook adopts a fixed-pitch hook beam, which is specially used for lifting steel ladle, while the secondary hook cooperates with the main hook to complete steel dumping, steel slag handling and other auxiliary lifting tasks. The operation mechanism and main electrical equipment are integrated inside the main girder, and the electrical room of the main girder is equipped with a chiller to ensure the stability of the equipment operation. In addition, the bottom of the main girder is equipped with heat-insulating boards along the span direction, which effectively reduces the heat radiation effect of molten steel on the metal structure.

YZS type adopts the structure of main and vice double trolley, four beams and four rails, which mainly consists of bridge, main trolley, vice trolley, hook beam, trolley running mechanism and electrical system. The main trolley runs on the main girder track on the outside of the bridge and is responsible for lifting the ladle of molten steel, while the vice trolley runs on the vice girder track on the inside of the bridge, which can traverse the underside of the main trolley and complete the tasks of molten steel dumping and slag handling through the hook and the main hook in cooperation. The running mechanism of the trolley adopts four-corner drive form to ensure smooth operation. In addition, the crane is equipped with special electronic scales and obvious display devices in the driver's room and on the bridge, which are convenient for real-time monitoring and operation. Both structural designs embody the features of high efficiency, safety and adaptability.
