Break Seized Chain Pins Fast — No Torches. No Hammering.
Jammed conveyor chain pins in steel mill drags stop production fast and force immediate repair.
Why Pins Seize in Steel Mills
Heat, scale, and corrosion pack tight into pin bores until the pin locks solid. Steel mill drags run hot and dirty, accelerating wear and binding. When a pin jams, production loss and safety risks climb fast.
Why This Failure Happens
WH132, WDH159, and ER864 pins seize when scale, fines, and corrosion load the joint, creating galling and thermal lock. Heat and thermal cycling distort plates and bushings, tightening the bore onto the pin. Shock loads from uneven drag loading drive the pin deeper, locking the chain and halting the conveyor instantly.
