Continuous Annealing Line

We can provide annealing line for stainless steel, continuous annealing line and hood-type annealing line. Different annealing furnaces can be designed based on different energy sources according to your requirement, and different thermal treatment is applied on different processing material.

The technology is that strip is paid-off and delivered into the annealing furnace continuously, so that the harden strip can be annealed. There are two kinds of furnace, horizontal furnace and vertical furnace.
