Special Requirements of Metallurgical Overhead Cranes

Metallurgical overhead cranes, due to their unique operating environments, have specific requirements that differentiate them from standard bridge cranes. These requirements are crucial for ensuring safe and efficient operations in metallurgical facilities. Let's delve into the key aspects that highlight the special demands placed on metallurgical overhead cranes:

  1. Adaptation of Electrical Equipment: The electrical equipment and components of metallurgical cranes must be suitable for the working environment. In conditions where the temperature exceeds 40°C, it is essential to utilize H-class insulation electric motors or implement appropriate measures. Additionally, reliable thermal insulation and cooling measures should be employed for electrical control devices.
  2. High-Temperature Resistant Cables: The cables used for laying in metallurgical overhead cranes should be high-temperature resistant and flame-retardant to withstand the demanding conditions of the environment.
  3. Temperature Regulation in Workshops with Heat Sources: For workshops such as steelmaking and continuous casting that have heat sources, the electrical rooms should be equipped with cooling fans. The temperature in the electrical rooms should generally not exceed 35°C. Non-conductive rubber mats should be laid on walkway floors for safety.
  4. Control Mechanism for Hoisting Machinery: When using electric hoists as the lifting mechanism for overhead cranes, it is recommended to adopt control methods that are distant from heat sources to ensure safe and efficient operation.
  5. Enclosed Operator Cabins: Cranes operated from driver cabins should feature enclosed cabins with cooling fans to maintain a comfortable working environment. Effective insulation layers made of flame-retardant materials should be installed for added safety.
  6. Radiation Protection: Anti-heat radiation devices should be installed beneath the main beam's lower cover, except when lifting containers with top covers.
  7. Overspeed Protection: The hoisting mechanism should be equipped with overspeed protection devices to prevent accidents caused by malfunction or overspeed, such as falling or overloading incidents.
  8. Specialized Electric Motors: The electric motors used in the hoisting mechanism should be specifically designed for lifting and metallurgical applications to ensure optimal performance and safety.
  9. Safety Measures for Contactor-Controlled Brakes: When utilizing contactor-controlled brake actions in the hoisting mechanism, precautions should be taken to prevent control failures due to a single contactor damage or adhesion. Dual braking systems should be implemented for added safety.

These special requirements underscore the critical need for tailored solutions in the design and operation of metallurgical overhead cranes to meet the stringent safety and performance standards of the steel industry.
