Energy saving periodic operation furnace is a trolley furnace with super energy saving structure. The trolley adopts anti-collision sealing brick, automatic brick turnover mechanism, automatic sealing trolley furnace door, integrated rail connection, without foundation installation, can be used when it is placed on the horizontal ground fixed with foundation pad iron expansion screw. It is mainly used for quenching, annealing aging of high chromium high manganese steel castings, nodular cast iron, roll, steel ball, 45 steel stainless steel, as well as heat treatment of various mechanical parts.
The shell of this series electric furnace is welded by steel plate section steel, the bottom of furnace body is connected with trolley light rail. Users don't need to install the foundation, they just need to put it on the flat cement floor. The furnace lining adopts light refractory brick as lining, which can save about 80% energy compared with traditional brick furnace. Long fiber thorn blanket, diatomite brick vermiculite powder are used as thermal insulation materials. Heavy anti-collision brick heavy high aluminum anti pressure brick are used for furnace mouth. The labyrinth refractory material is used between the furnace body the trolley, a self acting sealing mechanism is used to reduce the heat radiation convection loss of the electric furnace, the furnace temperature uniformity can be achieved. The heating elements are made of high-temperature resistance alloy wire, which are distributed on the furnace side, furnace door, back wall laying trolley wire laying bricks, are fixed with national standard socket bricks. The trolley is equipped with pressure high temperature resistant steel casting furnace bottom plate to carry the workpiece. In order to prevent the oxide skin falling into the heating element through the gap between the furnace bottom plate causing the heating element damage, the plug-in contact is adopted between the furnace bottom plate the furnace body. In order to ensure normal use, it is necessary to purge the oxide scale under the bottom plate of the trolley furnace frequently. Generally, once a week, lift the furnace bottom plate purge the oxide scale in the resistance wire groove with compressed air. Pay attention to prevent the oxide scale causing short circuit in the furnace wire.
Furnace door device structure
The furnace door device is composed of furnace door, furnace door lifting mechanism furnace door pressing device. The furnace door shell is made of welded section steel plate, with a solid frame structure, which is stacked with fire-resistant fiber pressing module. It requires good heat preservation performance light weight. The lifting device of furnace door adopts electric device, which is mainly composed of furnace door frame, furnace door lifting beam, reducer, chain wheel, transmission shaft bearing. The furnace door lifting is driven by forward reverse transmission on reducer. The furnace door lifting reducer is also equipped with a brake device, which can effectively prevent the furnace door displacement during the lifting process. The furnace door pressing device adopts the domestic advanced spring type pressing structure. When the furnace needs to be lifted, the self weight of the furnace door will automatically release the furnace door through the lever, move it horizontally out of a certain distance, then rise. When the furnace door is lowered in place, the furnace door is put down on the pulley on the trolley to be compressed, the spring elasticity will move the furnace door horizontally into the compression sealing state through the lever The pressing device makes no friction between the fiber surface on the furnace door the cotton at the furnace mouth, which has the characteristics of long operation mission.
