Due to other reasons such as the need to install heating elements on the inner wall of the furnace, the cross-sectional area of the furnace opening on the furnace body of most small well-type annealing furnaces is usually smaller than the cross-sectional area of the furnace chamber. Such settings lead to larger diameters such as steel coils When the wire rod is annealed, the diameter of the steel bar coils placed in t

The invention relates to the technical field of metal smelting, in particular to an annealing furnace with a coil expanding function and an annealing process thereof.The annealing furnace comprises a furnace body, a furnace opening is formed in the furnace body, a furnace cover used for controlling the furnace opening to be opened and closed is further arranged on the furnace body, and the cross section area of a cavity of the furnace body is larger than that of the furnace opening; a plurality of heating resistance wires are arranged on the side wall of the furnace body cavity, a guide device used for guiding one end of a metal wire to a designated position in the furnace body is detachably arranged at the furnace opening, and a locking device used for locking the end of the metal wire led into the furnace body cavity is arranged beside the side wall of the furnace body cavity. A winding roller is arranged at the center of the bottom of the furnace body, and a winding device used for enabling the locking device to rotate around the winding roller is further arranged in a cavity of the furnace body. The small well type annealing furnace has the effect of improving the energy utilization rate of single annealing of the small well type annealing furnace with the cross section area of the furnace mouth smaller than that of the furnace body chamber.
Description
technical field [0001] The present application relates to the technical field of metal smelting, in particular to an annealing furnace with an expanding function and an annealing process thereof. Background technique [0002] The well-type annealing furnace is mainly composed of electric furnace body, furnace lining, furnace cover, heating elements and other components. It is mainly suitable for annealing heat treatment of coiled wire rods, copper parts, stainless steel, steel strips and metal parts. [0003] Due to other reasons such as the need to install heating elements on the inner wall of the furnace, the cross-sectional area of the furnace opening on the furnace body of most small well-type annealing furnaces is usually smaller than the cross-sectional area of the furnace chamber. When the wire rod is annealed, the diameter of the steel bar coils placed in the annealing furnace can only be set from a small size according to the size of the furnace mouth, so that a...
