Abstract
The utility model relates to a smelting furnace, in particular to a ferrochrome smelting furnace lining. A blast-furnace crucible is composed of a furnace shell, a copper cooling wall layer, a small carbon brick layer, a carbon ramming mass layer and a large carbon brick layer. Refractory bricks (7) with different heights are built on the furnace wall of a crucible lining layer and the furnace bottom, the lower portion of a crucible lining is provided with a graphite carbon fiber thermocouple (5), the bottom layer of the crucible is formed by building a plurality of layers of furnace bottom carbon composite bricks (8), and the bottoms of the furnace bottom carbon composite bricks are provided with furnace bottom protection linings (9). The refractory bricks built on the furnace wall of the crucible lining layer and the furnace bottom are arranged in sequence in a concave-convex mode. The furnace wall of the blast-furnace crucible lining layer and the furnace bottom are built by the refractory bricks arranged in sequence in the concave-convex mode, the erosion intensity of molten iron to the blast-furnace crucible lining can be reduced, the erosion of molten iron flowing to the crucible lining is restrained, the area of the erosion layer of the shell is increased, and the service life of the blast-furnace crucible is prolonged.
Description
Technical field
The utility model relates to a kind of smelting furnace, particularly relates to a kind of ferrochrome smelting furnace liner.
Background technology
Ferrochrome is the important additives of refining iron and steel, the blast furnace crucibe of refining ferrochrome requires cupola well each several part to have good heat conductivility, in the blast furnace crucibe of smelting chromium irons, molten iron impacting heat flux intensity is high, and molten iron is the basic reason that causes cupola well to damage to washing away and corroding of cupola well.In addition the one side that, molten iron is close to basque surface forms protective layer because the lower meeting of hearth wall temperature is set in basque surface.For extending the service life of blast furnace crucibe; avoid the corrosion to basque of molten iron and slag and wash away; in guaranteeing that furnace lining surface temperature control is below 1,000 degrees Celsius; reduce the impact resistance of molten iron, increasing the protective layer area of molten iron in liner is the key that guarantees the safe handling of ferrochrome steelmaking furnace cupola well.
Summary of the invention
The purpose of this utility model is to provide a kind of ferrochrome smelting furnace liner, this blast furnace crucibe is by furnace wall and the concavo-convex orderly refractory brick of masonry of well at basque layer, suppress the erosion of molten iron flow to bottom lining, increase crust body erosion aspect long-pending, the service life of improving blast furnace crucibe.
The purpose of this utility model is achieved through the following technical solutions:
A kind of ferrochrome smelting furnace liner; formed by furnace shell, copper cooling wall layer, fritter carbon brick layer, the carbon element ramming bed of material, carbon block layer; it is characterized in that; there is the different refractory brick of height the furnace wall of basque layer with masonry of well; basque bottom is provided with celion thermocouple; cupola well bottom by multihearth at the bottom of carbon composite brick build by laying bricks or stones and form, furnace bottom carbon composite brick bottom is provided with furnace bottom protection lining.
Described a kind of ferrochrome smelting furnace liner, the furnace wall of basque layer described in it and the refractory brick of masonry of well are concave-convex ordered arrangement.
Advantage of the present utility model and effect are:
1, the utility model is provided with celion thermocouple, can detect temperature in stove at any time, improves carbon ferrochrome smelting quality.
2, between the utility model copper cooling wall and the carbon element ramming bed of material, be provided with fritter carbon brick layer, improved the thermal conductivity factor of the carbon element ramming bed of material, be conducive to guarantee temperature in stove, improve the service life of furnace wall.
3, the furnace wall of the utility model basque layer and furnace bottom are all built concavo-convex orderly refractory brick by laying bricks or stones, can reduce the scouring intensity of molten iron to blast furnace crucibe liner, suppress the erosion of molten iron flow to basque, increase crust body erosion aspect long-pending, the service life of improving blast furnace crucibe.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
Mark in figure: 1 is furnace shell, 2 is copper cooling wall, and 3 is fritter carbon brick layer, and 4 is the carbon element ramming bed of material, and 5 is celion thermocouple, and 6 is carbon block layer, and 7 is refractory brick, and 8 is furnace bottom carbon composite brick, and 9 is furnace bottom protection lining, and 10 is air port.
As shown in Figure 1, the utility model is a kind of ferrochrome smelting furnace liner.This blast furnace crucibe is by furnace shell 1, copper cooling wall 2, and fritter carbon brick layer 3, the carbon element ramming bed of material 4, celion thermocouple 5, carbon block layer 6, refractory brick 7, furnace bottom carbon composite brick 8, furnace bottom protection lining 9, air port 10 forms.By build fritter carbon brick layer 3 by laying bricks or stones between copper cooling wall 2 and the carbon element ramming bed of material 4, improve carbon element ramming bed of material operating temperature, make the conduction of cupola well heat smooth and easy.Basque bottom is provided with celion thermocouple 5, can detect temperature in stove at any time, guarantees that the safety of smelting process is carried out, and improves carbon ferrochrome smelting quality.The furnace wall of basque layer is all built the different refractory brick 7 of height by laying bricks or stones with furnace bottom, and refractory brick is concave-convex ordered arrangement.Different by build height by laying bricks or stones at basque, arrange orderly refractory brick gear and protect brick, can significantly reduce the scouring intensity of molten iron to blast furnace crucibe liner, suppress the erosion of molten iron flow to basque, increase molten iron and condense into the area that corrodes layer at liner surface.Cupola well bottom by multihearth at the bottom of carbon composite brick 8 build by laying bricks or stones and form, furnace bottom carbon composite brick bottom is provided with furnace bottom protection lining 9.
Claims (2)
1. a ferrochrome smelting furnace liner; formed by furnace shell, copper cooling wall layer, fritter carbon brick layer, the carbon element ramming bed of material, carbon block layer; it is characterized in that; there is the different refractory brick (7) of height the furnace wall of basque layer with masonry of well; basque bottom is provided with celion thermocouple (5); cupola well bottom by multihearth at the bottom of carbon composite brick (8) build by laying bricks or stones and form, furnace bottom carbon composite brick bottom is provided with furnace bottom protection lining (9).
2. a kind of ferrochrome smelting furnace liner according to claim 1, is characterized in that, the described furnace wall of basque layer and the refractory brick of masonry of well (7) are concave-convex ordered arrangement.
