Abstract

A kind of batch-type furnace chamber structure, including housing are the utility model is related to, the case inside wall is provided with refractory casting layer；The refractory casting layer is embedded with refractory fiber floor；The bottom of the refractory casting layer is embedded with fire brick layer；The refractory fiber floor is provided with least two layers, and the fire brick layer is located at the interlayer of refractory fiber floor.The burner hearth of this programme forms using castable refractory is integrated poured, can improve burner hearth sealing, can extend burner hearth service life.

Description

A kind of batch-type furnace chamber structure

Technical field

The utility model provides a kind of batch-type furnace chamber structure, belongs to firing equipment technical field.

Background technology

Batch-type furnace is mainly used in metalwork heat treatment, typically exists in heat treatment process to furnace atmosphere and requires.It is existing Batch-type furnace burner hearth be built into mostly using refractory brick, between refractory brick easily produce crack, cause hearth sealability poor, air Enter from crack in burner hearth, destroy furnace atmosphere.

The content of the invention

To solve the above problems, the utility model provides a kind of batch-type furnace chamber structure, concrete scheme is：

A kind of batch-type furnace chamber structure, including housing, the case inside wall are provided with refractory casting layer；The refractory casting Layer is embedded with refractory fiber floor；The bottom of the refractory casting layer is embedded with fire brick layer；The refractory fiber floor is provided with least Two layers, the fire brick layer is located at the interlayer of refractory fiber floor.

Further, the fire brick layer is spliced by the U-shaped refractory brick of polylith, the opening court of the U-shaped refractory brick Upper setting.

Further, the U-shaped refractory brick of the fire brick layer is spaced set.

Further, the U-shaped refractory brick of the fire brick layer is to be staggered.

Beneficial point of the present utility model is：The burner hearth of this programme forms using castable refractory is integrated poured, can improve Burner hearth sealing, refractory fiber floor is embedded in refractory casting layer, can further prevent refractory casting layer from ftractureing, extension uses the longevity Life；It is high to intensity requirement because burner hearth bottom needs to carry workpiece weight, fire brick layer is embedded in burner hearth bottom, stove can be improved The intensity of thorax bottom.In improvement project, fire brick layer can be risen using the U-shaped brick splicing set upward, U-shaped brick to refractory casting layer To preferable fixation, its intensity can further improve.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the structural representation of fire brick layer in the utility model.

Embodiment

A kind of batch-type furnace chamber structure as shown in Figure 1, 2, including housing 1, the madial wall of housing 1 are provided with refractory casting Layer 2；The refractory casting layer 2 is embedded with refractory fiber floor 3；The bottom of the refractory casting layer 2 is embedded with fire brick layer 4；Institute Refractory fiber floor 3 is stated provided with least two layers, the fire brick layer 4 is located at the interlayer of refractory fiber floor 3.

The fire brick layer 4 is spliced by the U-shaped refractory brick of polylith, the opening up setting of the U-shaped refractory brick.Institute The U-shaped refractory brick for stating fire brick layer 4 is spaced set.The U-shaped refractory brick of the fire brick layer 4 is to be staggered.

The burner hearth of this programme forms using castable refractory is integrated poured, burner hearth sealing can be improved, in refractory casting layer In be embedded refractory fiber floor, can further prevent refractory casting layer ftracture, increase the service life；Because burner hearth bottom needs to carry Workpiece weight, it is high to intensity requirement, fire brick layer is embedded in burner hearth bottom, the intensity of burner hearth bottom can be improved.In improvement project, Fire brick layer can be played preferable fixation to refractory casting layer, can be entered one using the U-shaped brick splicing set upward, U-shaped brick Step improves its intensity.
