Molten steel produced through the reaction of iron oxide and aluminum is cast at a temperature exceeding 3500 °F into refractory molds designed to suit the rails to be welded. This process features our CJ One-Shot Crucible, which is available for all of our current thermite welding processes. We offer a full range of rail welding kits to suit all rail sections including Worn Rail Welding and Wide Gap Welding. The One Shot Crucible is tapped at the bottom, the molten steel flows into the mold, fusing with the rail ends and forming the weld. The breakdown time starts after the last drop pours, allowing the entire setup to progressively cool. After the recommended time, the mold is removed and the weld is cleaned and finished by grinding to produce a smooth joint.
