Abstract
The invention provides a method for producing flame path wall of a high-performance monolithic refractory material carbon roasting furnace, which is characterized in that the flame path wall of the high-performance monolithic refractory material carbon roasting furnace is manufactured into a refractory concrete precast piece in advance, and is lifted in the furnace for assembly to complete the laying operation, or a casting or tamping method is adopted, the flame path wall is directly processed in the furnace to complete the laying operation. The production method comprises a material formula, a product matrix phase composition and a concrete construction method. The flame path wall is widely applied to new building, general overhaul or local repairing of the flame path wall of the carbon roasting furnace.
Description
Technical field:
The invention belongs to roaster technical field, be specifically related to a kind of production and construction method of indefinite fire-resistant material charcoal calcining fire wall of energy-saving high-performance for aluminum electrolyzing cell used carbon product sintering typing.
Technical background:
Carbon roasting furnace quirk wall is the main body of heater in the carbon roasting furnace.The quality of quirk wall performance directly influences service life of quirk wall.Because carbon roasting furnace needs to adorn repeatedly, go out carbon product in the course of the work, variations in temperature is big in the stove, easily causes the body of heater cracking; Again because long-term high temperature action easily causes the body of heater depressed deformation.The carbon roasting furnace quirk wall of current China all adopts chamotte brick and a small amount of high-alumina brick to build by laying bricks or stones.
The problem of brick quirk wall is a lot, and the most key problem has three, and the one, because brickwork joint is a lot, globality is poor, the overall construction intensity of masonry is not high under the high temperature, cracking and distortion easily during the quirk wall uses.The 2nd, because brick quirk wall construction labour intensity is big, efficient is low.The 3rd, because refractory brick will consume a large amount of energy aborning; And the described prefabricated flame path wall of Chinese patent CN2354092Y, CN201081549Y and CN1374495A is earlier the quirk wall to be prefabricated into big part, smallclothes or sub-assembly outside stove, and composite assembly forms in stove then.They structurally can solve the problem of quirk wall globality preferably, do not resolve the problem that thermal shock resistance is poor, creep rate is low and efficiency of construction is still lower but exist on the main performance of product.Owing to serviceability and life-span that these products all do not have fundamentally to improve carbon roasting furnace quirk wall, therefore fail in the actual use of industrial input.
For this reason, the invention provides a kind of production method of high performance indefinite fire-resistant material charcoal calcining fire wall.Its purpose is to overcome the major defect that current quirk wall exists aspect serviceability, improves quirk wall thermal shock resistance, creep resistance and bulk strength thereby reach, and the minimizing body of heater cracking and the distortion of maximum possible improve quirk wall life-span and efficiency of construction.This kind is energy-saving, high-performance, indefinite fire-resistant material charcoal calcining fire wall, can be newly-built at carbon roasting furnace quirk wall, use in overhaul or the modular repair.
Summary of the invention:
Raw-material material, granularity, the amount of allocating into, production method and aspects such as the use carbon roasting furnace, construction method thereof that the present invention uses when carbon roasting furnace quirk wall is made have proposed a kind of preparation method of high performance indefinite fire-resistant material charcoal calcining fire wall.
Carbon roasting furnace quirk wall of the present invention comprises composition, construction method of factory formula, the matrix phase of quirk wall etc.
It is characterized in that: this high performance indefinite fire-resistant material charcoal calcining fire wall can be made into the refractory concrete prefabricated component in advance, hangs in assembling in the stove then, finishes and builds operation by laying bricks or stones.Also can adopt the method for cast or the method for ramming in carbon roasting furnace, to construct, finish and build operation by laying bricks or stones directly this high performance indefinite refractory material.
