The Mill Products Division has the capability to quench and temper
carbon and alloy steel bars in water, oil, or polymer. We can handle
round bars in diameters from 7/16 inches to 12 inches. We can also
heat treat flats and squares as thin as 1/4 inch in thickness and
up to 12 inches in width. Depending on the size and grade of the
bar, we can handle lengths up to 53 feet.
All
of our high temperature furnaces are gas fired roller hearth furnaces.
They are open fired and direct fired into the furnace chamber. Most
of what we heat treat is in the hot rolled as rolled condition.
All of our tempering
furnaces are continuous gas fired recirculating furnaces. After
bars are quenched, they are placed on the entrance table of the
tempering furnace. At this point the bars begin to travel the full
length of the furnace. Every inch of every bar passes through the
entire length of the furnace. This assures that the bars are evenly
tempered and that the hardness is uniform throughout the length
of the bar.
