THERELEK BELL ANNEALER

  • Product Overview

    Bell Annealer brings in excellent temperature uniformity, consistent quality and good production rates

    Bell Furnace is suitable for black, bright and spherodized annealing of steel coils, non-ferrous strips, wires and general heat treatment processes upto 1100°C

    Bright annealing of cold rolled steel strip coils, and heat treatment of medium and thick hot-rolled plate, long products and wire coils are done using bell type furnace

    Type of furnace is usually rectangular or cylindrical form, single or multi-stack gas or electrically heated.

    Continuous purging of ammonia is deployed throughout the annealing cycle to avoid decarburizing.

    Overhead crane is used to load the base and move the equipment

    Coils are tilted to the right position and placed on the annealing base.

    The convection and heat transfer occurs in the base assembly

    Forced atmosphere circulation is used with the help of radial fans for temperature upto 950°C to improve convection.

    The cooling happens when furnace is removed with inner cover acting as protective atmosphere
    In both strip annealing and wire annealing, the convection flow goes up on the sides and down the center.
