Abstract
The invention discloses a kind of reinforced steel belt type reducing furnace burner hearth, including support, furnace shell, masonry for furnace wall, furnace roof；Furnace shell is that horizontally-arranged rectangular box, furnace shell made of metal blank are supported by support；Furnace roof, masonry for furnace wall are arranged in furnace shell inwall, and furnace roof is covered on masonry for furnace wall top, surround hollow burner hearth；Furnace roof cross section is ∩ shapes；Further improvement is that：Masonry for furnace wall is four-layer structure, for thermal insulation layer, outer furnace wall, midfeather, the internal protecting wall inwardly assembled successively from furnace shell inwall；Thermal insulation layer is the warming plate being made of high temperature silicic acid aluminium, and outer furnace wall is assembled using soft clay insulating brick, and midfeather is assembled using mullite insulation brick, and internal protecting wall is high-alumina refractory brick.Structural strength of the present invention, rigidity are high, and heat-proof quality is good.
Description
Technical field
The present invention relates to a kind of equipment technology field of powder metallurgy industry, more particularly to a kind of steel belt type reducing furnace stove
Thorax.
Background technology
Steel belt type reducing furnace is the visual plant of iron powder reducing, and the burner hearth cross section of existing steel belt type reducing furnace is rectangle,
This burner hearth is simple to manufacture, but structural strength, poor rigidity.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes that one kind can significantly improve structural strength and rigid reinforced steel band
Formula reduction furnace burner hearth.
The present invention is achieved through the following technical solutions technical goal.
Reinforced steel belt type reducing furnace burner hearth, including support, furnace shell, masonry for furnace wall, furnace roof；The furnace shell is to use metallic plate
Horizontally-arranged rectangular box, furnace shell are supported by support made of material；The furnace roof, masonry for furnace wall are arranged in furnace shell inwall, furnace top cover
Close on masonry for furnace wall top, surround hollow burner hearth；It is theed improvement is that：The furnace roof cross section is ∩ shapes.
In said structure, the masonry for furnace wall is four-layer structure, for the thermal insulation layer, outer inwardly assembled successively from furnace shell inwall
Furnace wall, midfeather, internal protecting wall.
In said structure, the thermal insulation layer is the warming plate being made of high temperature silicic acid aluminium, and outer furnace wall is protected using soft clay
Warm brick is assembled, and midfeather is assembled using mullite insulation brick, and internal protecting wall is high-alumina refractory brick.
The present invention compared with prior art, has the positive effect that：
1. furnace roof cross section is ∩ shapes, chamber structure intensity and rigidity are significantly improved.
2nd, masonry for furnace wall is four-layer structure, for inwardly assembled successively from furnace shell inwall thermal insulation layer, outer furnace wall, midfeather,
Internal protecting wall, there is preferable heat-proof quality.
3rd, thermal insulation layer is the warming plate being made of high temperature silicic acid aluminium, and outer furnace wall is assembled using soft clay insulating brick, middle
Wall is assembled using mullite insulation brick, and internal protecting wall is high-alumina refractory brick, has enough intensity under high-alumina refractory brick high temperature,
Mullite firebrick high temperature resistant, intensity are high, thermal conductivity factor is small, and soft clay insulating brick has preferable resistance to elevated temperatures, silicic acid
Aluminium warming plate, low thermal conductivity, heat-proof quality is good, and high temperature resistant, in light weight, stability is good, four kinds of different materials insulations, makes burner hearth
Heat scatters and disappears small, and the thermal efficiency is high.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
The invention will be further described below according to accompanying drawing and in conjunction with the embodiments.
The burner hearth of reinforced steel belt type reducing furnace shown in accompanying drawing, including support 1, furnace shell 2, masonry for furnace wall 3, furnace roof 8；Furnace shell 2
For the horizontally-arranged rectangular box made of metal blank, furnace shell 2 is supported by support 1；Furnace roof 8, masonry for furnace wall 3 are arranged in furnace shell 2
In wall, the cross section of furnace roof 8 is ∩ shapes, covers on the top of masonry for furnace wall 3, surrounds hollow burner hearth.
Masonry for furnace wall 3 is four-layer structure, for inwardly assembled successively from the inwall of furnace shell 2 thermal insulation layer 3.1, outer furnace wall 3.2, in
Partition 3.3, internal protecting wall 3.4, in the present embodiment, thermal insulation layer 3.1 is the warming plate being made of high temperature silicic acid aluminium, and outer furnace wall 3.2 is adopted
Assembled with soft clay insulating brick, midfeather 3.3 is assembled using mullite insulation brick, and internal protecting wall 3.4 is high-alumina refractory brick.
