Method for correcting deformed fire path wall of roasting furnace

Abstract

The invention discloses a method for correcting a deformed fire path wall of a roasting furnace. The correcting method performs completely correction for the deformed area of the fire path wall on the basis of a designed wall-correcting machine. The wall-correcting machine consists of a cross wall pushing plate (1), a horizontal hydraulic cylinder (2), a hinge support seat (3), a machine frame (4), a longitudinal wall pushing plate (5), a lower longitudinal hydraulic cylinder (6), an upper longitudinal hydraulic cylinder (7), a wall protection plate (8) and a balancing weight (9), wherein the longitudinal wall pushing plate and the cross wall pushing plate of the wall-correcting machine are aligned to a convex surface of the deformed fire path wall and not aligned to a concave surface of the deformed fire path wall, therefore, a rectangular material box located by the convex surface of the deformed fire path all is the place where the wall-correcting machine is mounted; the interior of the rectangular material box is provided with two layers of carbon anode blocks and is uniformly paved with auxiliary materials in a layered manner; and the concave surface of the deformed fire path wall must be an empty box so as to contribute to correcting the deformed fire path wall. The method is simple and practical, has good effect, does not influence normal work, does not damage the deformed fire path wall and can obtain greater economic benefits to a user.

Description

technical field [0001] The invention belongs to the technical field of electrolytic aluminum anode roasting furnaces, in particular to a method for correcting deformed flue wall of a roasting furnace. Background technique [0002] The roasting furnace is one of the key equipment for the production of electrolytic aluminum prebaked anodes. The longitudinal flue wall and transverse flue wall of the roaster are made of refractory bricks to form rectangular material boxes with equal volumes. Three layers of carbon anode blocks can be stacked in each rectangular material box. There is a longitudinal fire channel between the material boxes, through which the carbon anode blocks in each rectangular material box can be heated, and the heating temperature can reach 1150 degrees Celsius, which means that the wall of the fire channel should gradually change from the ambient temperature Raise to 1150 degrees Celsius to adapt to the work of the roasting furnace. At this time, the flue w...

Problems solved by technology

The static pressure type school wall device has a small amount of correction at one time, and requires multiple corrections for the deformed flue wall. The work is labor-intensive, low-technical, low in user acceptance, and it is difficult to promote.

[0005] There are no related reports on other correction methods for the deformed flue wall of the roaster
