Metallurgical overhead crane is one of the core equipment applied in steelmaking and continuous casting processes. It is mainly used for pouring molten iron into the converter in the converter charging span, transporting molten steel to the refining furnace in the refining span, and transferring molten steel to the continuous casting rotary ladle platform in the molten steel span.
The operation and control of the 260t metallurgical overhead crane is relatively sophisticated; however, it can be easily mastered once the operating rules are understood. As metallurgical cranes adopt short-time duty system, the motor operates according to the specified cycle under constant load conditions. If the motor fails to reach complete thermal stability, it can meet the operating requirements after stopping operation for a period of time for cooling.
When the crane is lowering loads, the transmission control is realized through self-excited dynamic braking. Though applicable to the same working scenarios as other braking methods, this approach eliminates the need for a transformer. It reduces costs while achieving braking and deceleration effects and cutting operating expenses. Therefore, this crane transmission mode features excellent economic performance and has been widely adopted.
The 260t metallurgical overhead crane has the advantages of light weight, compact structure and improved space utilization.
