Product Details

Our long rod induction quenching and tempering line is an integrated continuous heat treatment device equipped with advanced IGBT medium frequency induction power. It completes automatic feeding, rapid quenching, circulating cooling, low-temperature tempering and unloading in one flow for carbon steel and alloy steel long rods.

Supported by PLC intelligent control and infrared temperature monitoring, the line delivers even heating effect, stable hardness, small deformation and zero surface decarburization. Modular adjustable structure adapts to rod blanks of different diameters and lengths.

It cuts energy consumption by 40% above with no exhaust pollution. Simple touch screen operation reduces labor input. Processed long rods obtain balanced hardness and toughness, perfectly suitable for manufacturing long shafts, piston rods and high-strength mechanical fasteners.
