Roller hearth furnaces in a controlled atmosphere for bright annealing of tubes: the ICMI solution
ICMI Industrial Furnaces strengthens its international presence in the metal tube heat treatment sector by securing a second major order from a prestigious tube manufacturer. This project confirms the company’s specialization in the design and manufacture of controlled atmosphere roller hearth furnaces for bright annealing and continuous heat treatment processes for metal tubes and bars.
ICMI has engineered this particular line to ensure high thermal uniformity and precise control of the protective atmosphere, both essential factors in the bright annealing process of stainless steel tubes, special steels, and metal alloys.
Bright annealing of tubes in a controlled atmosphere
In the bright annealing process, controlling the atmosphere inside the industrial furnace is essential to prevent surface oxidation and ensure high-quality surface finishes on the treated tubes. For this reason, ICMI Industrial Furnaces designs and manufactures complete lines integrated with controlled atmosphere generators developed to guarantee process stability and production repeatability.
The supplied plant includes:
- continuous roller hearth furnace for heat treatment;
- controlled atmosphere generator;
- preheating chamber;
- semi-automatic loading and unloading systems;
- water or forced-air cooling units;
- motorized inlet and outlet roller conveyors;
- bundle handling and bar singulation systems.
The configuration allows the treatment of metal tubes and bars with high production efficiency while maintaining constant metallurgical and surface quality of the material.
Modular structure and plug-in installation
One of the main strengths of the solution developed by ICMI Industrial Furnaces is the modular prefabricated structure of the entire heat treatment line.
The plant can be divided into preassembled modules, optimizing international shipping and installation operations. This configuration reduces assembly times and accelerates commissioning activities at the end customer’s facility.
As highlighted by the company:
“Our expertise in thermal processes and manufacturing experience allow us to prefabricate complete heat treatment lines, safely ship them worldwide, and install them in a plug-in configuration for rapid production start-up.”
