A repairing process for the heating coil of the steel claw straightening machine for aluminum electrolysis

Abstract

The invention discloses a repairing process for a heating coil of a steel claw straightening machine for aluminum electrolysis. The process comprises the steps that (1) the heating coil is dismounted; (2) the heating coil is repaired; (3) a mold is manufactured; (4) a coil foundation is manufactured; (5) the middle of the heating coil is constructed; (6) the interior of the heating coil is constructed; and (7) the constructed heating coil is installed after being maintained at the room temperature to be dried, after the coil is heated and dried, pig iron is taken out, and equipment can be put on production when the coil has no abnormal condition. The repairing process has the beneficial effects that the consumed time is short, the total cost is low, and cost decreasing and benefit increasing are facilitated for enterprises. By the adoption of the made-to-order mold manufactured according to the contraction ratio of steel claws, damage to the coil from the deformed steel claws is prevented.

Description

Technical field [0001] The invention relates to the field of aluminum electrolysis equipment, and relates to a repair process of a heating coil of a steel claw straightening machine for aluminum electrolysis. Background technique [0002] The steel claw straightening machine is one of the important equipment used in the anode carbon block assembly process in the electrolytic aluminum production process. In the process of recycling the electrolytic aluminum anode steel claws, the cast steel claws will gradually bend under the action of thermal stress, especially the deformation of the two steel claws on the outer side is most obvious. In order to ensure that the anode steel claws after being pressed off and shot blasted can be put into the "carbon bowl" of the anode carbon block, steel claw straightening machines are generally used in the industry to heat and straighten the bent steel claws. The principle of the steel claw straightening machine is: put the anode steel claw to be ...

AI Technical Summary

Problems solved by technology

Once the masonry inside the coil falls off, the induction coil can no longer be used

It takes a long time to repair and re-build the induction coil. Therefore, most enterprises adopt the method of purchasing finished induction coils to prevent the above accidents. However, the overall procurement cost is high, and it is not easy for enterprises to reduce costs and increase efficiency.
