Galvanized Steels Performance in Extreme Temperatures

3/4/2013Peeling is caused by metallurgical changes that create a series of closely spaced voids at the free zinc-alloy interface known as Kirkendall Effect. High temperatures above 480 F (250 C) will accelerate peeling and continued exposure can result in the zinc-iron alloy layers cracking and separating from the steel. low-temperature environments on HDG steel indicate a

How Temperature Conditions Affect Bearing

"If a bearing designed for operation at normal temperatures is used in an extremely high or low temperature environment, the bearing life and performance will be unsatisfactory," Leese says.

Within 20 seconds of entering the pellet mill, feed goes from an air-dry (about 10-12 percent moisture) condition at ambient temperature, to 15-16 percent moisture at 80-90 C. During subsequent compression and extrusion through holes in a ring' die, friction further increases feed temperature to nearly 92C.

The general rule is to provide the minimum viscosity required at the expected operating temperature: 100SUS (20cst) for roller bearings and 70SUS (13cst) for ball bearings. In addition, the increased thermal expansion of the shaft must be accounted for both axially (to ensure that high thrust loads are not induced) and radially (to ensure that radial internal clearance is
