Electric Hoist for Molten Metal: High-Temperature, Safe Lifting for Metallurgical Environments
The Electric Hoist for Molten Metal, also known as the Metallurgical Electric Hoist, is designed for lifting heavy loads, especially in environments involving molten metal handling. Typically installed on I-beam tracks, this hoist operates efficiently in a straight line or along a curve on the track, ensuring safety during operation. This version of the electric hoist is an enhanced iteration of the original CD and MD models, with specific modifications to suit the high-demand environment of molten metal lifting. It features high-temperature insulation protection and double-limit protection for the lifting mechanism.
- Lifting capacity: 2t～10t
- Lifting height: 9m-20m
- Lifting speed: 8（8/2）m/min, 7（7/1.75）m/min
- Running speed: 20m/min
- Work level: M6
Operating Environment
The electric hoist for molten metal is designed for environments without fire, explosion hazards, or corrosive media. It is typically used in conjunction with a metallurgical single-beam crane to lift molten steel in casting production lines.
For hoists with a rated lifting capacity greater than 5 tons, the electric hoist for molten metal is equipped with a working brake and a safety brake at low speed. In the event of failure of the working brake or a breakdown of the transmission components, the safety brake can reliably support the rated load. For hoists with a rated lifting capacity of 5 tons or less, the electric hoist for molten metal is designed to handle 1.5 times the rated lifting capacity.
However, the electric hoist for molten metal should not be used in environments with temperatures below 10°C or above 50°C, in explosive hazard areas, or in places filled with sulfuric acid or corrosive gases. It is also prohibited from lifting toxic or flammable materials to ensure safety and reliability.
Product Advantages
- The electric hoist for molten metal operates at the highest duty level of M6.
- The hoist mechanism consists of a supporting brake and a safety brake. In case of failure of the conical electric motor brake or intermediate drive, the DC electromagnetic brake installed on the high-speed shaft of the reducer or the ratchet brake on the drum starts to act, braking the load to prevent stalling.
- Features dual-limit and dual-limitation functions.
- Load weight limitation protection at startup.
- High-temperature insulation protection.
- The insulation grade of the hoist motor and working motor is H-grade, with an overheating protection device inside the hoist motor windings.
- The steel wire rope is made of high-strength, high-temperature-resistant steel rope, specially designed for metallurgical applications.
- The Electric Hoist for Molten Metal uses remote control as the preferred method of operation, ensuring ease of use.
- The product’s working grade reaches M6, the protection level is IP54, and the motor insulation grade is F-grade. When used outdoors, protective devices must be installed, and it is not suitable for use in environments with relative humidity greater than 85%.
