Abstract
The utility model discloses a furnace lining structure of ore furnace cooling method technology. A material poring layer, dense high-aluminum bricks I, high-conductivity graphite blocks and high-heat-conductivity charcoal blocks are sequentially laid on the furnace bottom of an ore furnace from bottom to top, graphite tiles, low-porosity charcoal blocks and dense high-aluminum bricks II are sequentially arranged on the furnace wall of the ore furnace from outside to inside, and semi-graphite charcoal-silicon carbide bricks are arranged on the periphery of an iron outlet of the furnace wall of the ore furnace. The furnace lining structure adopting the technical scheme adopts high-heat-conductivity materials, further optimizes material quality, reasonably matches materials on iron port parts, solves the problems that iron slag easily penetrates through the furnace bottom and furnace slag strongly corrodes a furnace lining, reduces destroy of flame-retardant materials of the furnace lining by smelting process, prolongs the service life from three months to more than three years or even longer, and greatly prolongs the integral service life of the ore furnace lining.
Description
Technical field
The utility model relates to a kind of furnace lining structure, specifically relates to a kind of furnace lining structure used when adopting the cooling method technology.
Background technology
What the hot stove furnace lining structure in present domestic ore deposit adopted is the thermal-insulating method furnace lining structure, and promptly at the base upper berth at furnace bottom position 1-2 layer asbestos board, side is built one deck light-weight insulating brick, up flat again 6-8 layer high-alumina brick or the clay brick built, and the furnace bottom end face is 3 layers of brick fuel.And at the furnace wall position: being close to the furnace shell steel plate is the thick alumina silicate fiber felt of one deck 30-40mm, and side ring is built one deck light-weight insulating brick inward, builds one deck high-alumina brick or clay brick for ring inward again, innermost working lining, and the bottom is a high-alumina brick.This furnace lining structure, for smelting the little alloy of proportion, as calcium carbide, effect is better.But the alloy bigger to proportion, as silicomangan, ferronickel, ferromanganese etc., because of smelting product than great, the slag that is easy to pierce the furnace bottom brickwork joint and smelts one of product furnace lining is had strong corrosivity, thereby result of use is bad, and the life-span is shorter.
Summary of the invention
The technical problems to be solved in the utility model is when the heavy metal of mine heat furnace smelting, prevents to cause at the bottom of the slag anvil poke that furnace bottom charcoal piece floats and to the corrosion of furnace lining, provides a kind of hot stove furnace lining structure in ore deposit of long service life.
For achieving the above object, the utility model is by the following technical solutions:
In the utility model, the laying cast bed of material, dense form high-alumina brick I, height are led graphite block and high heat conduction charcoal piece to hot stove furnace bottom successively from bottom to up in the ore deposit; The hot stove furnace wall in ore deposit is followed successively by graphite tile, low-porosity charcoal piece and dense form high-alumina brick II from outside to inside; Schungite carbon-silicon carbide brick is set around the tapping hole of the hot stove furnace wall in described ore deposit.
Establish blind hole in the described schungite carbon-silicon carbide brick, graphite cannula is set in the blind hole.
End face between the adjacent high heat conduction charcoal piece of every row is the inclined-plane.
Above described high heat conduction charcoal piece, protection tile is set.
Adopt the utility model of technique scheme, adopt the material of high heat conduction, the material quality is further optimized and iron oral area position material reasonably combined, when having solved the restriction mine heat furnace smelting than great metal, slag iron bores at the bottom of the poke easily, and slag has reduced the destruction of smelting process to fire proof material of furnace lining to the strong corrosion of furnace lining, greatly improved the whole service life of ore deposit hot stove furnace lining by bringing up in 3 months more than 3 years even longer service life.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the hot stove in ore deposit;
Fig. 2 is the structural representation at tapping hole position in the utility model.
The specific embodiment
What as shown in Figure 1, the utility model was related is the improvement of the hot stove in ore deposit whole furnace lining from the furnace bottom to the furnace wall.
Specifically, the laying cast bed of material 9, dense form high-alumina brick I 7, height are led graphite block 10 and high heat conduction charcoal piece 1 to the hot stove furnace bottom in ore deposit successively from bottom to up.End face between the adjacent high heat conduction charcoal piece 1 of wherein every row is the inclined-plane, and the angle of inclination difference on inclined-plane in every high heat conduction charcoal piece 1, can strengthen the frictional force between the high heat conduction charcoal piece 1 like this, prevents that " lot " and " floating " phenomenon from appearring in high heat conduction charcoal piece 1.In addition, can also above high heat conduction charcoal piece 1, protection tile 6 be set, at the bottom of preventing that better slag from boring poke, the sealing of steel plate of furnace hearth bottom, and use boiler exhaust gas machine exhausting, and make on the furnace bottom thermoisopleth and move, make alloy be difficult for piercing furnace lining.
The hot stove furnace wall in ore deposit is followed successively by graphite tile 4, low-porosity charcoal piece 2 and dense form high-alumina brick II 5 from outside to inside.And lead at graphite tile 4 and height and to lead little swollen ramming mass 8 with height between graphite block 10 and the dense form high-alumina brick I 7 and fill.Need to prove, hot slag line position, ore deposit is the furnace lining weakest link, be close in the furnace wall position outside that the furnace shell of furnace wall periphery is inboard builds a floor height conductive graphite watts 4, and the outside water spray that adopts of furnace shell is forced cooling, promptly need set up several spray heads outside the furnace shell of furnace wall position.When furnace shell external refrigeration intensity was enough big, the hot-fluid that is transmitted to furnace wall-slag interface by the burner hearth high-temperature region was equal to or less than the heat flow that furnace shell transmits, and slag is solidifying at the interface, formed nature furnace lining protection furnace wall slag lining.
As shown in Figure 2, the schungite carbon-silicon carbide brick 3 of high heat conduction is set around the tapping hole of hot stove furnace wall in the ore deposit, anti-ly wash away, thermal shock resistance is good, establish blind hole in the schungite carbon-silicon carbide brick 3, graphite cannula 11 is set in the blind hole, graphite cannula 11 arranged outside graphite bricks 12, thus make the iron mouth operate easily and change conveniently.
Principle of the present utility model is:
The utility model is used highly heat-conductive material and furnace wall water-cooled, shifts making the furnace lining cooling by the heat with furnace lining, and is lower than the fusing point of itself material.Produce the condensate layer slag like this; forming one deck has the skull of protective effect; this skull is wrapped in the high temperature surface of refractory material; it will make refractory material and high temperature completely cut off; play the effect of protection furnace lining; adopt oblique building by laying bricks or stones at furnace bottom in addition, prevented " lot " and " floating " of furnace bottom charcoal piece, extending furnace lining life.Because the furnace shell structure that shields is more loose, thermal conductivity factor is lower, has reduced the interior heat of burner hearth and has has outwards scattered and disappeared, and has reduced energy consumption.In furnace lining structure, reduced simultaneously the consumption of refractory material, thermal resistance between course of reaction and the cooling system is diminished, increased the stove internal volume, reduced investment cost, shorten the set-up time, thereby reached ore deposit hot stove safety, energy-conservation, efficient, long-lived purpose.
