Further, the rollway is liftable is arranged on by lowering or hoisting gear, and specially rollway is fixed on feed and risen On falling unit, feed lowering or hoisting gear is fixed on melt pit.
Further, the boss of furnace bottom doorframe can be embedded in by being provided with the fire door, and the periphery of boss is provided with ring The insulation quilt of shape, improve the sealing thermal insulation effect of fire door.
Further, the heat-insulation layer is using aerosil nano heat insulating material.
Further, the thermal conductivity factor of the heat-insulation layer is 0.017-0.023w/mk.
Further, the connected mode of first aluminium foil layer and ceramic fiber layer is riveting.
Further, the resistance wire is processed helically shaped using nickel chromium triangle high-temperature alloy.
Further, the furnace roof cross section of the body of heater is arc, avoids dust from being deposited in furnace roof, influences electric furnace heating effect Fruit.
Compared with prior art, side blow-on door is changed to furnace bottom opening structure by the utility model, and fire door is placed in into stove Bottom, rise because when gases are heated, they expand, when opening workpiece in fire door replacing stove, hot gas moves upwards, from furnace bottom stove gate stream The heat gone out is considerably less, and most heats are still stored in stove, and in-furnace temperature will not excessively decline, and is sent second batch workpiece After entering in stove, stove heat temperature raising is given, in-furnace temperature will soon reach requirement, save heat energy, improve heat utilization efficiency, again Shorten every time change workpiece after give furnace warming time, improve work efficiency, simultaneously because shortening warm-up time, workpiece enters After entering in stove, temperature will soon be raised to the temperature needed for converted products, improve product quality.
Thermal conductivity factor is used as aerosil nano heat insulating material heat-insulation layer conduct O.017-0.023w/mk Main heat preservation component in industrial furnace liner, the heat preservation component of ceramic fiber layer and aluminium foil layer collectively as furnace lining is combined with, when When the thickness of industrial furnace liner reaches 190mm, if 850 DEG C of in-furnace temperature, furnace wall temperature only rises 3-5 DEG C than room temperature, protects If warm 3 hours, furnace wall temperature can rise 8-10 DEG C, compared to other industrial furnace liners, there is obvious energy-saving effect, even if It is substantially thinner than other industrial furnace liners on thickness if furnace wall temperature is identical.
A brick will be put on stove inwall and is changed to the less step bricks of thermal conductivity factor, resistance wire is placed in the stepped groove of step bricks, Reduce heat loss caused by putting a brick, effectively save the energy.
In summary, the utility model has the advantages of applied widely, easy to use, high insulating effect, energy-conserving and environment-protective.
