High Hydrogen Gas Bright Belt Annealing Furnace for Steel: Eco-Friendly Solution from China's Leading Suppliers and Factory
Product Introduction
The bright belt annealing furnace is an advanced industrial equipment used for non-oxidative heat treatment of metal coils, pipes, wires, etc. in a protected atmosphere or vacuum environment. Its core objective is to eliminate internal stress in the material, improve mechanical properties, while maintaining the original bright surface of the metal and avoiding the formation of oxide scales and decarburization layers.
The core principle is to isolate oxygen. The workpiece is placed inside a sealed inner cover, evacuated or filled with high-purity inert/reducing protective gases (such as a nitrogen-hydrogen mixture), and then heated through the outer cover. The main features of this equipment include:
-
🌡️Uniformity and Precise Control of Furnace Temperature Utilizing strong convective circulation technology, the temperature difference within the furnace can be kept within ±5℃, ensuring uniform material properties. The entire process is automatically controlled by a computer, which is precise and reliable.
-
⚡High Production Efficiency The "double furnace base" design is commonly adopted. When one furnace base is in heating mode, the other can be cooled and loaded, enabling quasi-continuous production. The loading capacity of a single furnace can reach 30 tons, resulting in high production efficiency.
-
🌿Green and Environmentally Friendly After annealing, the surface is bright and free of oxidation, eliminating the need for the traditional acid washing process after annealing. This fundamentally solves the problems of acid pollution and wastewater treatment.
This equipment is applicable to a variety of metal materials and is mainly divided into two categories:
Finished bright annealing of copper and copper alloys, aluminum alloys, etc.
Intermediate or finished annealing of coil and wire products such as stainless steel, silicon steel, ordinary carbon steel, alloy steel, etc.
The full automatic control system controls and manages the whole process of heating, heat preservation and cooling of each hood furnace, providing reliable guarantee for the production of users.
Secondary air inlet and saturated steam are used to convert coal into carbon monoxide gas and feed it into a covered furnace for combustion and heating. The proportion of air intake and steam to coal seam is automatically controlled by PLC system, and slag is automatically discharged.
