Product Description

Thermit Welding

Thermite welding is a track connection construction process with mature technology, simple, convenient, fast, and high-quality construction.Rail thermite welding is the thermite flux composed of aluminum powder, iron oxide and other metal additives in a special crucible, and a high temperature match is used to ignite the thermite reaction. During the reaction, a large amount of heat is released and the molten alloy mixture reacts to form.Because of its high density, molten steel sinks below, the slag generated by the reaction is relatively light and floats on the upper part, and the molten steel is filled with sand in a short time.At the same time, the aluminum hot molten steel itself acts as a filler metal, crystallizes and cools together with the molten steel rail, and the two steel rails form a whole.

The main process of the thermite welding

Preparation → Rail head cleanning and Rust removal→ adjusting Rail head distance → installation mold and clamping tools → Sealing → Preheating →Crucible installation → ignition → reaction → demoulding → remove mold and weld head → grinding
