Steel Mill Equipment

Belleville disc springs are performing important maintenance and safety functions worldwide in steel producing mills.  Their heavy duty spring forces are being used to keep high voltage electrode clamping devices tightly connected insuring the full energy load is being delivered to smelting pot operations.

Stacks of large, heavy bellevilles are designed into the latching devices on coke oven doors to ensure efficiency and help prevent loss of oven temperature. Belleville stacks are also employed in the tracks of rolling mills to help keep them balanced and producing consistent thicknesses of rolled steel.  A steel mill has many bus bar and other bolted connections that can suffer the effects of thermal expansion/contraction or simple vibration that can be rectified with disc spring pressure.
