      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 & 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.
      🌡️ Uniform & Precise 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.

      ⚡ 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.

      🌿 Green & Environmentally Friendly

      After annealing, the surface is bright and free of oxidation, eliminating the need for the traditional acid washing process. 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 more.

      ⚙️ Ferrous Metals

      Intermediate or finished annealing of coil and wire products such as stainless steel, silicon steel, ordinary carbon steel, alloy steel, etc.

      🖥️ 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.
      🔥 Gas Conversion Heating: 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 a bright belt annealing furnace and how does it work?
      A bright belt annealing furnace is an industrial heat treatment equipment designed to anneal metal coils, pipes, and wires without causing surface oxidation. It works by sealing the workpiece inside an inner cover, removing oxygen through evacuation or filling the chamber with protective gases (such as nitrogen-hydrogen mixtures), and then applying heat via an outer cover — resulting in a bright, oxide-free surface finish.
      Q What metals can be processed in a bright annealing furnace?
      The furnace is suitable for both non-ferrous metals (such as copper, copper alloys, and aluminum alloys) and ferrous metals (including stainless steel, silicon steel, carbon steel, and alloy steel). It supports intermediate or finished annealing for coil and wire products across these material types.
      Q How accurate is the temperature control inside the furnace?
      Thanks to strong convective circulation technology, the temperature uniformity within the furnace can be maintained within ±5℃. The entire heating, heat preservation, and cooling process is managed by a fully automatic computer control system, ensuring precise and consistent results across each production cycle.
      Q Does bright annealing eliminate the need for acid washing?
      Yes. Because the annealing process takes place in an oxygen-free environment, the metal surface remains bright and free from oxide scale after treatment. This completely eliminates the need for traditional post-annealing acid washing, which in turn resolves issues related to acid pollution and industrial wastewater treatment.
      Q What is the "double furnace base" design and what are its benefits?
      The double furnace base design allows two furnace bases to operate in alternating cycles — while one base is in the heating phase, the other is simultaneously being cooled and loaded with new material. This enables quasi-continuous production, significantly improving throughput and reducing idle time. A single furnace can accommodate a loading capacity of up to 30 tons.
      Q How is the heating fuel managed and controlled in this furnace?
      The furnace uses a coal-gas conversion system where secondary air inlet and saturated steam convert coal into carbon monoxide gas, which is then fed into the covered furnace for combustion heating. The ratio of air intake and steam relative to the coal seam is automatically regulated by a PLC control system. Slag discharge is also automated, reducing manual intervention and improving operational efficiency.
