Abstract
The utility model provides a kind of energy-saving magnesia carbon brick heat-treatment furnace, comprises preheating device, main thermal, magnesia carbon brick stacking room.The utility model have employed waste heat recovery processing system, is imported by heat in another preheating device, plays the pre-heat effect to magnesia carbon brick, thus has saved resource, serves energy-conservation effect.Meanwhile, the heating wire of temperature-controllable ensure that shape and the performance thereof of magnesia carbon brick.
Description
Technical field
The utility model relates to a kind of heat-treatment furnace, particularly relates to a kind of energy-saving magnesia carbon brick heat-treatment furnace.
Background technology
At present, magnesia carbon brick is widely used in smelting iron and steel production as refractory material, and the liner tile generally as ladle uses.China is big steel country, and the annual magnesia carbon brick quantity consumed reaches more than 200 ten thousand tons, and discarded magnesia carbon brick reaches more than 600,000 tons, these used refractory are used as garbage disposal mostly, only have on a small quantity by coarse utilization, this not only wastes resource, and pollutes environment.Part domestic steel mill handle subsidizes converter again with rear magnesia carbon brick and electric furnace is lining with, to reduce the consumption of refractory material, some employing waste magnesia carbon bricks are processed into particle as electric furnace inserts, when the fire-resistant factory particularly had produces magnesia carbon brick and Al2O3C Bricks, add a small amount of with rear magnesia carbon brick and continuous casting alumina-carbon material, to reduce costs.But this coarse utilization, significantly reduces the performance of product, brings adverse influence to result of use.Except there is certain deficiency in the processing technology of magnesia carbon brick, the phenomenon that also existence wastes energy on the heat-treatment furnace heated magnesia carbon brick, cost is higher.How more efficient process due to magnesia carbon brick needs to use a large amount of heats, and therefore the energy consumption of its heat-treatment furnace is very high, utilize waste heat, and makes heat supply loop more easy to control, and this is problem demanding prompt solution.
Utility model content
For solving the problem, the utility model provides a kind of energy-saving magnesia carbon brick heat-treatment furnace, comprises preheating device, main thermal, magnesia carbon brick stacking room.Main thermal comprises heating wire, waste heat recovery processing system.Preheating device comprises blower fan, and preheating device is connected with main thermal by pipeline.Magnesia carbon brick stacks room between preheating device and main thermal.
Preferably, the cladding material of heat-treatment furnace is common brick.
Preferably, the quantity of heating wire is 8-15.
Preferably, the pipeline thermal conductive pipe of preheating device inside that comprises preheating device and the connecting pipe of waste heat recovery processing system and communicate with connecting pipe.
Preferably, connecting pipe is provided with by-pass valve control.
The utility model have employed waste heat recovery processing system, is imported by heat in another preheating device, plays the pre-heat effect to magnesia carbon brick, thus has saved resource, serves energy-conservation effect.Meanwhile, the heating wire of temperature-controllable ensure that shape and the performance thereof of magnesia carbon brick.
Accompanying drawing explanation
Fig. 1 is energy-saving magnesia carbon brick heat-treatment furnace top view.
In figure, 1 is heating wire, and 2 is preheating recovery and processing system, and 3 is connecting pipe, and 4 is preheating device, and 5 is blower fan, and 6 is magnesia carbon brick stacking room, and 7 is main thermal.
Detailed description of the invention
In the present embodiment, energy-saving magnesia carbon brick heat-treatment furnace comprises preheating device 4, main thermal 7, magnesia carbon brick stacking room 6.Main thermal 7 comprises heating wire 1, waste heat recovery processing system 2.Preheating device 4 comprises blower fan 5, and preheating device 4 is connected with main thermal 7 by pipeline.Magnesia carbon brick stacks room 6 between preheating device 4 and main thermal 7.
In the present embodiment, first utilize last time heat treated waste heat to carry out preheating to magnesia carbon brick, preheating is realized by preheating device 4.Be preheating to certain hour, opening power, start main thermal 7, the temperature of heating wire 1 is set in 600 DEG C-900 DEG C.Heated at constant temperature 8-26h is carried out by main thermal 7 pairs of magnesia carbon bricks.Energy-saving magnesia carbon brick heat-treatment furnace is when heating magnesia carbon brick, and heating, while transfer to preheating device 4 by heat by connecting pipe 3.Preheating device 4, except the function with preheating, also has waste heat recovery and leads to waste heat carries out post bake effect to magnesia carbon brick.Connecting pipe 3 is provided with by-pass valve control, waste heat can be controlled and whether transmit.
These are only the utility model preferred embodiment, therefore can not limit the scope of the utility model enforcement according to this, the equivalence namely done according to the utility model description changes and decoration, all should belong in the scope of the utility model covering.
