Wheels and Sheaves

The cost of wheels can be reduced by finishing ODs before flame-hardening. We can work with wheels made of cast iron, ductile iron or steel.

Sheaves require groove-hardening only. Flame-hardening is a fast and economical method to achieve this.

Cams

Flame hardening of cams provides a superior wear surface on outside diameter cams, box cams, or barrel cams. This is accomplished by only selectively hardening the cam paths. This eliminates the need for costly die tool steels or thru-hardening of the cams. Our process also reduces the finishing time of the cams. If improved core properties are required, starting with a pre-heat treated grade of steel in the range of 280 to 320 brinell would be recommended.

Cable Drums

For either cast or fabricated cable drums flame-hardening is an ideal application. Our proven method of flame-hardening drums minimizes or eliminates distortion by allowing us to selectively harden only the groove area.

Chicago Flame Hardening has flame-hardened cable drums in excess of 30 ft. long and 10 ft. in diameter, weighing up to 100,000 lbs. Our capacity in this area is one of the largest in the country.
