High Hydrogen Gas Bright Belt Annealing Furnace from China Suppliers | Eco-Friendly Factory Solutions for Steel Production
Product Introduction
The bright blet 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.
Core Principles and Characteristics
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:
1. Uniform Temperature Control
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.
2. 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.
3. Green & Eco-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.
Application Scope
This equipment is applicable to a variety of metal materials and is mainly divided into two categories:
- Non-ferrous metals: Finished bright annealing of copper and copper alloys, aluminum alloys, etc.
- Ferrous metals: 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.
Frequently Asked Questions (FAQ)
What is the primary purpose of a bright belt annealing furnace?
The primary purpose is the non-oxidative heat treatment of metal coils, pipes, and wires. It eliminates internal stress and improves mechanical properties while keeping the metal surface bright and free of oxide scales.
How does the furnace prevent metal oxidation during heating?
It isolates oxygen by sealing the workpieces inside an inner cover. This cover is either evacuated or filled with high-purity inert or reducing protective gases, such as a nitrogen-hydrogen mixture, before heating.
What temperature uniformity does this equipment offer?
By utilizing strong convective circulation technology, the temperature difference inside the furnace is strictly controlled to remain within ±5℃, ensuring uniform material properties.
How does the "double furnace base" design improve production efficiency?
The design allows quasi-continuous production. While one furnace base is undergoing the heating process, the other base can be cooled and loaded, supporting a single-furnace capacity of up to 30 tons.
Why is this annealing process considered environmentally friendly?
Because the process prevents oxidation, the metal surface remains clean and bright. This eliminates the need for traditional post-annealing acid pickling, fundamentally resolving acid pollution and wastewater treatment issues.
What control system manages the heating and combustion processes?
The entire process is managed by an automatic PLC system. It automatically controls the proportion of air intake and steam to the coal seam, manages heating and cooling, and automates slag discharge.
