NIEL FOR STEEL MILLS (DC Motors) part -1

PART -1

One of the oldest and most pertinent questions that Mill owners and Engineers ask me is, should we choose AC motors or DC Motors to run our plant ?

The answer is different for different applications, and different installations in different conditions.

Typical Possibilities:

1. New plant - Small

2. New Plant - Large

3. Integrated Steel Plant

4. Old plant upgrade

5. New Plant remote location

6. Technical strategies are different for different types as above.

Another set of criteria can be:

1. Cost of Power

2. Quality of Power Supply

3. Availability of Skilled Labour

4. Availability of Capex and so on...

Each of the above calls for a deeper study.

Over the last 50 years, we have been one of the largest suppliers of Motors to the Steel Sector across 45 countries. This experience has given me a rather rich insight into this industry and its many challenges.

In one sentence, if you are setting up a large capacity STEEL unit higher than 5 Million Tons Per Year (5 MT/Y), with a good quality power supply, located near an industrial hub then go for AC Motor & AC controls, else choose DC Motors and DC Controls. Over the next few weeks I shall try to explain myself in more detail.

Will be Happy to take any questions to answer to the Best of my knowledge.
