Bi-Metallic Perfomance at Economical Price

The advancement of clinker cooling technology over the last decade has significantly reduce the operating temperature of many cooler parts like clinker breaker hammers and clinker drag chain. The lower service temperature allows for the use of wider range of wear resistant alloy steels.

We have a selection of drag chain solutions, depending on the chain operating temperature.

1) HIGHER ULTIMATE AND YIELD STRENGTH
Most of the clinker drag chain supplied by other suppliers is made of 12-14% manganese steel, which has an ultimate strength of 125,000 psi and a yield strength of 60,000 psi. The Columbia Steel clinker drag chain made of H39 is more superior than clinker drag chain made of manganese steel because H39 has an ultimate strength of 210,000 psi and yield strength of 170,000 psi.

Benefits:
Less maintenance and likelihood of failure because the increased yield strength of the H39 (3X) compared to manganese will decrease the amount of “stretching” the chain links experience.
For “detachable style” clinker drag chain it is important that the “hook” portion of the chain link does not open up due to yielding as this could allow the integral link pin to escape. As a result of elongation on manganese steel, it is quite common that mill operators remove a chain link from time to time in order to maintain the chain tension.

2) LONGER SERVICE LIFE WITH H39 Steel and XTEND® OVERLAY – At least 2X increase in service life over Manganese Steel.

H39 has a hardness of 430 HB and is more abrasion resistant than Manganese steel (200-220 Hb).
We would recommend that the drag chain link should come with the Xtend® chrome carbide overlay (713 HB hardness), which will substantially increases the wear life of the drag chain.

Chain Operating Temp	Alloy Application
Less than 550°F (290°C)	High Strength Alloy Steel (H39) with Xtend® process overlay (bi-metallic hard facing), in which a layer of high chromium white iron is applied to high wear areas.
550°F to 1100°F (290°C to 580°C)	Our experience has shown that our Manganese Steel (G59) is the best wear material. A layer of our high chrome hard facing (Xtend®) can be applied to high wear area to increase service life.
Over 1100°F (580°C)	For very high temperature service, we recommend our SA2, which is a very quality heat resistant stainless steel

Aqua Alloy's Bearing Housing & Journal provides:-

• Longer Service Life
• Good Reliability
• Stronger Build
• Better abrasion resistance material
• Competitive Price

NOTE : Conventional cast iron bearing housing and fabricated welded joints couplings are not strong enough to withstand the high work load in abrasive and harsh environment and are thus prone to failure.

Users report :-

"We were using cast iron bushing with fabricated coupling (welded joints) in S45C material and they were lasting us less than 6 months. We were able to get 3X the life from Aqua Alloy bushing and coupling."

"We were previously using locally fabricated hanger bearings and they were wearing out in less than a year. We then installed Aqua Alloy bearing and it has been running for almost two years now without giving us any problem."

We keep in our inventory a wide range of bearings and journal housings of various OEM designs i.e FLS, Fuller, etc.
