New technology for diagnosing and commutation adjustment of direct current motors of primary drives of rolling mills

Efficient and reliable operation of rolling mills in many respects depends on reliability of direct current motors of primary drives, which is in large part determined by the conditions of commutation. Emergence of ring fire in the collector and increased sparking of the motor may cause the accident. Approximate cost of elimination of such accident may amount to tens of thousands rubles that convincingly confirms importance of vibration analysis and commutation adjustment of commutator electric machines of direct current.

The paper presents some results of examination of commutation conditions of motors of primary drives of finishing mill train 320 of JSC Metallurgical Plant in the Name of A.K. Serov and mill 800 of JSC Chusovoy Metallurgical Works.

We must conclude that the developed method of commutation adjustment in terms of operating conditions and application of a modern device system enables to reveal the reserve of use of the equipment installed. It results in the increase of productivity of rolling mills in whole or reliability of primary drive operation with lower operating costs.
