High Precision Seamless Steel Rail Aluminothermic Welding Services 

Product Introduction 

SINCHOLD rail aluminothermic welding is the welding method as a heat source in a chemical reaction, to improve the comfort. SINCHOLD rail aluminothermic welding the welding principle is through the configuration of thermit after a light reaction inside the crucible to form high temperature aluminum hot molten steel into welding sand mold and stay within the cavity of the rail, high temperature molten steel casting in rail welding, melting parts to be welded rail end face. After cooling solidification to be welded rail connected into a whole.

Product Feature and Application 

Using aluminothermic welding to Seamless connection in China is along with the development of railway high speed up.This new technology is quickly used on crane rail of many factories ,mines, coking industries,goods yards, ports and wharves. Application of aluminothermic welding technology in building, expanding or rebuilding or the whole seamless welding loader walking tracks, in order to satisfy the requirement of the mechanical smooth, safe driving, reduce the impact of rail and  foundation when locomotive is driving , overcome the temperature influence on the rail , reduces the equipment, rail, basic maintenance cycle and cost, lengthen the service life and greatly improve the efficiency and handling capacity of the equipment.
