Abstract
Forge furnace fire door structure, relates to a kind of forge furnace.Comprise by the bottom of top furnace roof, lower furnace and the fire door that surrounds of left and right side furnace wall, at the bottom of described lower furnace, comprise and be positioned at the concrete foundation of bottom and be arranged on inner side furnace bottom and the outside furnace bottom in concrete foundation, outside furnace bottom comprises along a plurality of reinforcement cast steel backplates that are laterally fixed on cross section in concrete foundation and are L-type, between the reinforcement cast steel backplate of L-type and inner side furnace bottom, form U-shaped groove, in the U-shaped groove forming between the reinforcement cast steel backplate of L-type and inner side furnace bottom, be filled with corundum castable.The utility model can be kept out refractory material due to the thermal expansion force that high temperature produces effectively by the reinforcement cast steel backplate of a plurality of L-types, also can avoid workpiece with fire door downside position, friction occurs when taking on and collide and cause breach.
Description
Technical field
The utility model relates to a kind of forge furnace, is specially a kind of forge furnace fire door structure.
Background technology
Forge furnace is in high-temperature heating process, and oven door sealing is vital.Fire door downside adopted laying fireproof bricks or was formed by castable cast in the past, and fire door directly compressing forms oven door sealing in smooth fire door surrounding.In actual mechanical process, cause that fire door is damaged even to be destroyed, thereby affect oven door sealing, reduction fire door mainly contains two reasons service life:
1, heated parts, when packing into and take out, is easy to, with fire door downside position, friction and collision occur, and the flame that fire door downside position produces in breach burner hearth is scurried out outside stove at a high speed.
2, under long-time hot environment, fire door place refractory material can produce thermal expansion force, causes fire door downside outwardly, cannot guarantee concordant at grade with other positions of fire door, and causing the fire door cannot excellent sealing, the flame in burner hearth is scurried out outside stove from gap.
Utility model content
The purpose of this utility model is in order to address the above problem, a kind of forge furnace fire door structure is provided, can effectively keep out refractory material due to the thermal expansion force that high temperature produces, also can avoid workpiece with fire door downside position, friction occurs when taking on and collide and cause breach.
The technical scheme that realizes above-mentioned purpose is: forge furnace fire door structure, comprise by top furnace roof, an at the bottom of lower furnace and left side, the fire door that right side furnace wall surrounds, it is characterized in that: at the bottom of described lower furnace, comprise and be positioned at the concrete foundation of bottom and be arranged on inner side furnace bottom and the outside furnace bottom in concrete foundation, described inner side furnace bottom comprises the common brick layer setting gradually from the bottom up, undercloak and high aluminium brick layer, outside furnace bottom comprises along a plurality of reinforcement cast steel backplates that are laterally fixed on cross section in concrete foundation and are L-type, a plurality of reinforcement cast steel backplates be evenly arranged and between leave gap, between the reinforcement cast steel backplate of described L-type and inner side furnace bottom, form U-lag, in the U-lag forming between the reinforcement cast steel backplate of L-type and inner side furnace bottom, be filled with corundum castable, the upper surface of corundum castable is concordant with the upper surface of inner side furnace bottom.
In above-mentioned concrete foundation, be embedded with and connect steel structure, the many J-shaped screw-thread steels that described connection steel structure comprises horizontally disposed steel plate and is connected to steel plate lower surface, the upper surface of described steel plate is concordant with the upper surface of concrete foundation; Described a plurality of reinforcement cast steel backplates below is provided with the channel-section steel that Open Side Down, strengthening cast steel backplate fixes by bolt and channel-section steel respectively, the lower end of channel-section steel is supported with vertically disposed support bar, the Plate Welding of the lower end of support bar and concrete foundation upper surface, the upper end of support bar and channel-section steel welding.
The utility model is provided with a plurality of reinforcement cast steel backplates that a row cross section is L-type in the fire door position of bottom furnace wall, between the reinforcement cast steel backplate of described L-type and inner side body of wall, form U-lag, and in U-lag, build corundum castable, by the reinforcement cast steel backplate of a plurality of L-types, can effectively keep out refractory material due to the thermal expansion force that high temperature produces, also can avoid workpiece with fire door downside position, friction occurs when taking on and collide and cause breach.
