Long Bar Heat Treatment Machine
Induction continuous heat treatment equipment for long bar heat treatment is a high-tech technology developed by applying induction heating technology. Thread rod induction hardening and tempering production line with low frequency or high frequency induction power supply is currently in leading technology and mature stage in China. The final products are widely used in some construction key projects, such as cross-sea bridge, nuclear power construction, and Western Gas Project, wind energy railway construction etc.
Long bar heat Treating is induction heating for bar hardening and tempering. Heat treatments available by induction hardening and tempering system, process includes heating and quenching, tempering and stress Relieving.
Duolin long bar heat treating line can process bar diameter from 6-100mm, length from 1000-14000mm, meet small & big production capacity.
