Iron and Steel Industry

Increasing furnace combustion temperature is an effective way to save fuel. Such approach to saving fuel can substantially improve performance of basic metals manufacture.

Heating up to 1100 - 1200°C and above in blast furnaces is caused by the use of oxygen. This is a typical oxidizing agent that increases combustion intensity of almost all substances when raising concentration in the air from 30%. Various metals and complex substances such as carbon, magnesium and iron are known to burn in oxygen.

Average iron and steel works producing 1 million tons of steel per year uses over 3 billion mᶾ of oxygen.

Such oxygen can be generated using adsorption and cryogenic oxygen units. Grasys is the only developer and manufacturer of high-performance adsorption oxygen units in Russia.

Compressor units to produce compressed air are used in ferrous and non-ferrous industry.

Compressed dry air is required to clean pipes of furnaces and heat exchangers, to blend products that ensure pneumatic mechanisms operation, control and automation devices.

High-quality air treatment (removal of moisture, mechanical impurities, oil vapors) is the most critical compressed air requirement for solutions in the iron and steel Industry. A multi-stage air cleaning and drying system is deployed to meet the desired requirements using air dryers, filters, coal columns.

Composition of a typical Grasys stationary air compressor system: compressor unit, air drying and purification system, monitoring and control system, storage receivers.

Grasys compressor units operate automatically, and ensure unmanned performance.
