      Product Details

      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.

      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:

      • 🌡️
        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.

      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 and related materials
      🔷 Ferrous Metals
      • Stainless steel coil and wire products
      • Silicon steel, ordinary carbon steel
      • Alloy steel (intermediate or finished annealing)
      💡

      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.

      ❓ Frequently Asked Questions
      Q What is the main purpose of a bright belt annealing furnace?
      A The bright belt annealing furnace is designed to perform non-oxidative heat treatment on metal coils, pipes, and wires in a protected atmosphere or vacuum environment. Its goal is to eliminate internal stress, improve mechanical properties, and maintain a bright, oxide-free metal surface — all without requiring post-process acid washing.
      Q How does the furnace prevent oxidation of metal surfaces during annealing?
      A The workpiece is sealed inside an inner cover that is either evacuated or filled with high-purity inert or reducing protective gases — such as a nitrogen-hydrogen mixture. This isolates the metal from oxygen throughout the entire heating process, preventing oxide scale and decarburization layer formation.
      Q What temperature uniformity can the furnace achieve?
      A Through strong convective circulation technology, the furnace maintains a temperature difference of within ±5℃ throughout the entire heating chamber. This ensures consistent material properties across the entire batch being processed.
      Q What types of metals can be processed using this equipment?
      A The furnace supports a wide range of metals. For non-ferrous metals, it handles copper, copper alloys, and aluminum alloys. For ferrous metals, it processes stainless steel, silicon steel, ordinary carbon steel, and alloy steel — covering both intermediate and finished annealing of coil and wire products.
      Q How does the double furnace base design improve production efficiency?
      A The double furnace base design allows one base to be in active heating mode while the other is simultaneously being cooled and reloaded with new material. This alternating workflow enables quasi-continuous production and significantly reduces downtime. A single furnace can handle a loading capacity of up to 30 tons.
      Q Is the bright belt annealing furnace environmentally friendly compared to traditional methods?
      A Yes. Because the annealed surface remains bright and oxide-free, there is no need for the acid washing process that traditional annealing requires. This eliminates acid pollution and wastewater treatment concerns entirely. Additionally, the PLC-controlled air and steam intake system ensures efficient fuel use and automated slag discharge, further reducing environmental impact.
