Steel production is one of an essential heavy industry, serving for basic construction but has a high potential for environmental pollution. Producing 1 ton of steel will emit 0.5 to 1 ton of slag, 10,000m3 of exhaust gas and 100kg of dust. Therefore, the dust extraction system is very important in the production process of the steel mill. This system helps protect the environment, worker’s health and the community, ensures continuous production with high intensity, and stable plant operation efficiency.

Thanks to the experience of using INVT’s GD5000 medium voltage inverter for the Venturi fan system in the past, Hoa Phat Steel Joint Stock Company has continued to trust in using GD5000 medium voltage inverter with capacity of 4000 kVA to control sintering furnace electrostatic dust collector.
