Abstract
The present invention provides a bake carbon flue straightener for straightening a flue wall of an anode baking surface from a deformed or bowed position to a straight or normal position. The flue straightener includes a plurality of remotely controlled and independently actuated hydraulic cylinders mounted on a plurality of elevations space apart at equal distances from each other, a steel frame for supporting hydraulic cylinders, such that each of the elevations of the hydraulic cylinders are coupled to a continuous length of extendable solid push plates for extending the push plates to the deformed or bowed flue wall so as to push or straighten with equally distributed forces the deformed or bowed flue wall back to the straight or normal position.

A bake carbon flue straightener for straightening a flue wall of an anode baking surface from a deformed or bowed position to a straight or normal position, said flue straightener comprising:
- a plurality of horizontally disposed remotely controlled and independently actuated hydraulic cylinders mounted on a plurality of elevations vertically spaced apart at equal distances from each other and operable as a unit,
- said cylinders being mounted with horizontal spacings and elevations with vertical spacings for positioning the cylinders to those locations on the wall determined to be deformed,
- a hydraulic control unit for actuating said hydraulic cylinders,
- a steel frame for supporting said hydraulic cylinders,
- each of said elevations of said hydraulic cylinders in a substantially horizontal direction coupled to a continuous length of one of a plurality of extendable solid push plates for extending said push plates to said deformed or bowed flue wall so as to push or straighten with equally distributed forces said deformed or bowed flue wall back to said straight or normal position.
In a bake carbon flue straightener for straightening a flue wall of an anode baking surface from a deformed or bowed position to a straight or normal position, said flue straightener including a plurality of remotely controlled and independently actuated hydraulic cylinders mounted at a plurality of elevations spaced apart at equal distances from each other, groups of said hydraulic cylinders vertically disposed at said elevations with respect to other groups of said hydraulic cylinders at other said elevations, a hydraulic control unit for actuating said hydraulic cylinders, a steel frame for supporting said hydraulic cylinders, each of said elevations of said hydraulic cylinders coupled to a continuous length of extendable solid push plates, the method comprising:
- the step of extending said push plates to said deformed or bowed flue wall so as to push or straighten with equally distributed forces said deformed or bowed flue wall back to said straight or normal position.
A flue straightener for straightening a bake carbon flue wall from a deformed or bowed position to a straight or normal position, said straightener comprising:
- at least one plurality of horizontally disposed hydraulic cylinders,
- said plurality of horizontally disposed hydraulic cylinders with at least one vertically disposed elevation,
- said horizontally and vertically disposed cylinders being spaced apart for positioning the cylinders to those locations on the wall requiring straightening,
- a hydraulic control unit for actuating said hydraulic cylinders individually or in unison for aligning to and pushing on said flue wall,
- a steel frame for supporting said hydraulic cylinders at said locations,
- each said plurality of horizontally disposed hydraulic cylinders coupled to a continuous length of one of a plurality of extendable push plates for extending said push plates to said deformed or bowed flue wall to push or straighten said deformed or bowed flue wall to said straight or normal position.
