Product Introduction

Foundry crane is used in the heat and high dust severe environment and lifting molten metal frequently with working duty A7. Main working process: used in converter adding material bay to charge hot metal to the converter and lift hot metal in refine bay to refine furnace or molten steel bay that lift molten steel to ladle turret. The crane is comprised of the bridge, trolley, long travel system, electrical equipment, etc. All of work operation can be finished in the cabin.

According to the needs of users and the working conditions of the crane, foundry cranes are generally divided into double-girder single trolley, four-girder four-track double-trolley type, and for the casting bridge crane of extra-large tonnage, the four-girder six-track double trolley structure type is adopted.

The Foundry crane is mainly composed of the main trolley, the auxiliary trolley, the bridge structure, the trolley operating mechanism, the gantry hook group, and the electrical control. The fixed gantry hook group is suspended on the main trolley by the wire rope, and the distance between the two hooks is fixed to lift the ladle. The two trolleys can be operated independently to complete various lifting operations, and can also be used together to complete the ladle tipping, residual steel, and waste slag operations.

Application

It is mainly used in the continuous casting technology of steel making for pouring melted iron from additive bay of converter to converter; lifting molten steel from refining bay to refining furnace or lifting molten steel from molten steel bay to ladle turret of continuous casting machine.

According to different use situation, suitable for high temperature steel workshop, aluminum workshop, copper workshop, heat treatment workshop and so on.
