The challenges
Once applied to cool the iron-making furnace equipment, the water is gravity fed upstream to a collection sink basin before being pumped onwards at a flow rate of 13,210 GPM (3,000 m³/h) to a heat exchange recycle system. However, the water that is collected in order to be reused has a very high level of contamination, with iron fragments, sand and mineral particles being present. The water needs to be filtered in order to remove stated contaminants before it can be pumped onwards.
Eaton Model
The solution
Since XINXING had utilized Eaton's filtration products in hydraulic applications for a number of years, a reputation for quality and service had been built up between the two companies. Via an Eaton distributor, a filtration specialist was invited to the iron and steel facility to closely examine the contamination issue. Following a period of consultation involving an in-depth technical discussion it was determined that the Eaton Model 2596 automatic self-cleaning strainer with a 3.9 mm (5/32
Results
In this application just one 30 in Model 2596 is used within the process, which replaced three sets of filters previously, saving a significant amount of space on the factory floor. Furthermore, 98% of the greater than 4 mm particles are removed from the water therefore reducing the potential for damage to upstream components.
The new system with the 30 in Model 2596 installed cut down on unplanned interruptions to the local heating system and reduced water consumption in the plant by 20% Plant
