Break Seized Chain Pins Fast — No Torches. No Hammering.
Seized drag chain pins from thermal cycling have your steel mill line down and losing production.
Why Pins Seize in Steel Mills
Steel mill heat, scale, and corrosion weld pins into the bushings. Thermal cycling tightens everything until the pin won’t move. Every hour down burns production, labor, and safety margin.
Why This Failure Happens
WH132, WDH159, and H-series drag chains pack tight with scale, corrosion, and abrasive fines. Thermal cycling expands the pin and bushing, forcing metal-to-metal galling under heavy load. The result is a seized pin that will not press out with hammers, rosebuds, or standard shop presses
