Steel

The steel industry produces a variety of products in multiple sizes and configurations with a wide array of finishes. The primary products include the following.

  • Hot Rolled Steel
  • Cold Rolled Steel
  • Coated Steel – Painted, Galvanized, Galvallume, and others
  • Steel Bars
  • Steel Wire
  • Steel Plate
  • Structural Steel
  • Steel Tube – ERW and Seamless
  • Stainless Steel

A steel mill uses a large amount of water and other aqueous fluids for a variety of purposes such as cooling, cleaning and lubrication. These fluids play a critical role in the manufacturing process. Throughout the process huge amounts of ferrous scale and fines are generated. There are several areas in the mill where ZGF technology can provide value by removing the contaminants from these fluids.

The primary contaminant in most steel mill process fluids is steel; such as steel fines, steel dust, steel particles and steel scale. Other contaminants include oil from lubrication processes, silt, dirt and suspended solids from “mill water” (typically, river water, lake water or well water) and air-borne / atmospheric dirt.

Zero Gravity Filters offers three patented separation / filtration technologies to meet the needs of the Steel Industry.

  • Maggie – Maggie is a fully automatic, in-line, high intensity, high efficiency, self-cleaning, patented magnetic separator.  Maggie is the best available technology for separating magnetic contaminants from process fluids.
  • Spring Filter – The ZGF Spring Filter is a 316 stainless-steel coil wound with a variable pitch that allows the filter element to open evenly from top to bottom ensuring that all contaminants are completely removed from the filter element with each backwash.  The “nidges” provide an absolute gap to ensure consistent and reliable particle capture. The Spring Filter element is utilized in the EZ Clean family of automatic filtration systems.
  • Tornado – The Tornado is high “G”-force, centrifugal separator.  The Tornado is a simple but extremely innovative device.  The Tornado has no moving parts and no media.  Tornado effectively removes particles without any regular maintenance.
  • MEC – The MEC is the only fully automatic, permanent media, in-line filter that combines magnetic and barrier filtration in a single system.  

With diminishing maintenance staffs and tighter profit margins, contamination control must be effective, consistent and reliable.

The selected filtration technology must be:

  • capable of removing small contaminants without negatively impacting the process fluid,
  • automatic to minimize operator involvement
  • relatively maintenance free

ZGF MaggieSpring Filter and Tornado technologies satisfy the criteria, and effectively and efficiently capture and remove the contaminants from the process.

ZGF technology can be installed in a variety of processes and applications.

To get a better understanding on where ZGF technology can provide value in the steel industry, click on one or more of the Process Diagram links below.  The process diagrams show you where a ZGF technology can be implemented in a specific process and the benefits it provides.

ZGF technology provides value

ZGF technology has been adopted as the best available technology by several steel manufacturing organizations.  As they continue to implement our technology and realize the exceptional value, some organizations have shared their success stories. 

Click on Success Stories to jump to the Success Stories / Case Studies page to learn how ZGF technology provides value.  Click on the links below to learn how our customers were able to reduce operating costs, improve process reliability and quality, and reduce the environmental footprint of their operations by implementing ZGF technology.

ZGF technology also provides value in facility support processes.  Click on the following links to find additional success stories in the following support processes.

ZGF Maggie, Spring Filter & Tornado technologies meet all purchasing and performance criteria by effectively and efficiently capturing and removing the contaminants from process fluids and process / cooling water.

ZGF technology will provide value because it is:

  • fully automatic
  • consistent & reliable
  • non-disposable
  • energy efficient - utilizing a minimal amount of electricity and air during purge/backwash
  • able to remove ferrous particles down to 1 micron and non-ferrous particles down to 20 micron
  • able to provide value throughout the mill and help optimize each process by effective and efficient contaminant capture and removal
  • environmentally responsible – does not generate additional waste, unlike bags, cartridges and roll media
