Abstract

The utility model discloses a honeycomb furnace bottom plate for a trolley resistance, relating to a furnace bottom plate and aiming at providing a honeycomb furnace bottom plate for a trolley resistance, wherein the honeycomb furnace bottom plate has the advantages of uniform force, less possibility of deformation and long service life, and comprises a square panel; the periphery of the lower surface of the square panel is provided with a side plate; a honeycomb grid framework is arranged on the lower surface of the square panel in the side plate; the honeycomb grid framework is connected with the side plate; and the edges of the two opposite sides of the upper surface of the square panel are provided with vertical baffle plates. The furnace bottom plate has the advantages that the design of the honeycomb grid framework is adopted to guarantee the heating uniformity and the less possibility of deformation; and force bearing points below the bottom plate are increased so as to enhance the service life of the furnace bottom plate and reduce the cost of the furnace bottom plate.

Description

A kind of chassis resistance furnace honeycomb briquet stove base plate

Technical field

The utility model relates to a kind of drop-bottom, relates in particular to a kind of chassis resistance furnace honeycomb briquet stove base plate.

Background technology

At present, the most frequently used drop-bottom is a monoblock or netted.The drop-bottom of monoblock does not have lacing wire, yielding more than 780～1000 degree high temperature for a long time, and the bottom heating is slow, and be subjected to various heavy casting and forgings and workpiece heat effect and irregular stressed influence, the phenomenon that occurs buckling deformation easily, also can crack, rupture when serious, cause it normally not use.When furnace bottom fire-resistant brick not at ordinary times, also can accelerate the drop-bottom deformation velocity.After the drop-bottom distortion, make the workpiece shove charge, go out extremely inconvenience of furnace operating, and, make also easily distortion thereupon of workpiece, cause workpiece normally not use because of the drop-bottom distortion.In addition, when the foreign material such as oxide skin of cleaning in the stove, also be difficult for drop-bottom is pulled out.When deflection is excessive, even can damage body of heater inside, accidents such as circuit breaking-up occur; Though and netted drop-bottom heating uniformity is protected, netted stress point is less, the refractory material under the drop-bottom is damaged by pressure to cause short circuit easily, and service life is just shorter.

The utility model content

At above-mentioned prior art, the technical problems to be solved in the utility model provide a kind of stressed evenly, long chassis resistance furnace honeycomb briquet stove base plate of not yielding and life-span.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of chassis resistance furnace honeycomb briquet stove base plate, comprise square panel, around the lower surface of square panel, be provided with side plate, be provided with the Cellular Networks framework on the square panel lower surface in side plate, the Cellular Networks framework also links to each other with side plate, and the edge, relative both sides of square panel upper surface also is provided with vertical baffle plate.

Compared with prior art, the utlity model has following advantage: the design of Cellular Networks framework, can guarantee being heated evenly property and gain in strength and make it not yielding, and increase the stress point under the base plate, also reduced cost the service life that has increased drop-bottom.
