Metallurgical Equipment

This equipment is a converter tilting device that provides power for the tilting of the furnace body:

The tilting device of the converter adopts a four point meshing full suspension torsion bar balance device structure.

The four point meshing has high working reliability and safety. The secondary reducer is fully suspended and lifted on the ear shaft of the support ring. This design allows the tilting mechanism to absorb the elongation and bending deformation of the support ring.

The primary reducer is mounted on the high-speed output shaft of the secondary reducer, allowing the primary reducer to also be fully suspended and mounted on the secondary reducer. This design is conducive to eliminating the three point ultra static support structure formed by the insertion of the primary reducer on the secondary reducer, greatly improving the distribution of shaft load and gear load, and facilitating equipment manufacturing and installation and disassembly of the primary reducer.

The torque bar balance device at the lower part of the secondary reducer is used to absorb the tilting torque generated during the tilting process of the converter and slow down the impact of converter tilting. This is very beneficial for reducing the impact load on equipment components and extending the service life of the equipment.

The four motors of the converter tilting device adopt AC variable frequency motors, which can be continuously adjusted.

Four electro-hydraulic push rod brakes provide reliable assurance for the stopping position of the converter.

The biggest advantage of using AC motor drive is that it reduces the maintenance and repair workload of the motor, and improves the reliability of the equipment.

During normal smelting of the converter, four motors operate simultaneously. When one motor malfunctions or is disassembled, the other three motors can still maintain normal operation for 24 hours. When two motors fail simultaneously, the other two motors can still maintain the ability to complete a furnace of steel.
