深圳Exothermic welding mold

Exothermic welding molds are mostly used for the link of railway tracks. The chemical reaction between aluminum and copper powder produces liquid high-temperature copper liquid, and the high temperature generated by the exothermic reaction is used to realize the modern welding process of high-performance welding. Exothermic welding is suitable for equipment connection of various metal materials such as copper and copper, copper and steel, and steel and steel.

The welding reaction is carried out in a high temperature resistant graphite mold. The mold adopts high density, which has the advantages of reasonable design, long life and good ease of use. It can withstand the melting temperature of copper, steel, iron and other metals. The flow direction, flow rate and final shape of the molten metal are strictly designed, and the service life of the mold is about 200 times.

The connection between the ground wire and the ground electrode adopts the exothermic mold welding method. The basic operating procedure for this new grounding method is very simple. That is, the grounding resistance must be less than 1, because the working ground, protection ground, lightning protection ground and anti-static ground are connected to the computer ground at the same time to form a common grounding network. When using conventional galvanized flat steel and angle steel for construction, the number of grounding electrodes must be increased to ensure that the grounding resistance meets the requirements.

Graphite mold for welding: The mold consists of mold cover, mold cavity, welding cavity, diversion groove, mold clamp and other parts. Exothermic welding mold model selection: The mold has different shapes of connections, such as straight-through, T-shaped, cross-shaped, etc.
