Iron & Steel Industry

Though you might not realize it, dry compressed air is used in every manufacturing unit in the Steel industry.

Use of Compressed Air in the Steel Industry

In Steel manufacturing units, generally, the following Compressed air powered pneumatic machines are used :

Jolt squeeze turnover machines
Bundling machine for semi-finished products
Pneumatic control and actuators

Applications

Ash Handling System
Injection molding
Coolant for hot tools and system
Assembling station powering
Spraying
Welding
Tool powering
Feeding of metal sheets
Conveying
Carbon reduction in steel production

Problems

A major problem in compressed air systems is the presence of water, dust particles, oil (oil particles are introduced by lubricated air compressors), and solid contaminants, which can adversely affect air quality.

If the contaminated compressed air is used through compressed air-powered pneumatic tools and machines, then there will be the following problems :

Malfunctioning of pneumatic tools and machines
Sluggish and inconsistent operation of valves and cylinder
Corrosion in pipelines, cylinders and other components
Increase in downtime
Increase in maintenance cost of pneumatic machines/tools/controls.
Freezing in exposed lines during cold weather.

The Delair Solution

Remove water, dust particles, oil (lubricated air compressors introduce oil particles), and solid contaminants from compressed air.

Delair offers a wide range of refrigeration and adsorption dryers that remove water/moisture from compressed air.

Delair Refrigeration Dryers

This dryer operates on the method of cooling the air to near freezing point to remove the moisture and reheating it to approximately 10°C below the incoming compressed air temperature at nominal conditions.

Delair Adsorption dryer

The dryer is based on the principle of heatless regeneration and the physical properties of the desiccant to adsorb and desorb water vapour. It uses the pressure swing principle / purge air to regenerate the desiccant bed.
