Abstract
The utility model discloses a roaster for a swinging sluice liner of a blast furnace. The roast consists of a U-shaped roasting tube 1 and a conduit 3, wherein flame holes 2 are uniformly distributed on one side of the roasting tube 1 along the central line of the roasting tube; two tube openings in the top of the roasting tube 1 are both sealed up; and the bottom of the roasting tube 1 is communicated with the conduit 3. When the swinging sluice liner is roasted, the roasters are arranged on two end surfaces which are less heated and rapid in heat radiation, of the swinging sluice liner, coal gas is introduced through the conduit and is ignited, and flame is ejected from the flame holes in the roasting tube, then the temperatures of the end surfaces of the sluice liner are greatly raised; and as the flame holes are uniformly distributed, parts of a sluice liner casting material are generally uniformly heated, and situations that the sluice liner is subjected to cracks, fissures and damage caused by non-uniform heating are effectively avoided. The roaster is simple in structure and has a remarkable effect, the probability that the swinging sluice liner is discarded because of the non-uniform heating in the roasting process is effectively reduced, and other fireproofing materials of the U-shaped structure can also be roasted.
Description
Technical field
The utility model relates to a kind of ironmaking production utility appliance, especially a kind of roaster for blast furnace swing chute liner.
Background technology
Blast furnace swing chute is located at the casting house end, is installed in below the casting house trough, and its effect is that a molten iron that flows out through iron runner is transformed into left and right sides any direction, injects under the casting house platform, rests in the hot-metal ladle and carriage on the railway line.The swing chute is made up of chute, supporting mechanism and tilting mechanism, directly contacts with high temperature liquid iron for avoiding the chute body, and chute needs the pouring fireproof material liner before use, to prolong its work-ing life.The chute liner is for forming by using mould material to pour into a mould after at the chute body particular manufacturing craft being installed.Owing to contain certain moisture in the liner of new cast, be situation such as guarantee the crack not occur after it comes into operation, damage, come off, must toast liner, so that the moisture evaporation in the mould material, and solidify to form high strength, wear-resisting, heat-resisting liner, the working condition requirement that washes away, corrodes to satisfy high temperature liquid iron.
In the practice, the baking and thermal insulation of swing chute liner generally realizes by the method for burn wood and coke-oven gas.Because being middle ship shape roomy, that two ends are narrow, swing chute body constructs, therefore the fuel of placing at roomy position, chute middle part is more relatively, be heated bigger at the bake process middle part, two ends are heated slightly little, add that the chute thickness of inner lining is more than 300mm, and the direct ingress of air heat radiation in two ends is very fast, causes inconsistent, the suffered stress intensity difference of thermal expansivity of each position mould material of chute liner thus, thereby makes the chute liner produce crack, crackle, damage phenomenon.The chute liner is in case damage then can not be come into operation cast again after need scrapping.Be not damaged when toasting behind the liner in pouring in the chute for guaranteeing to swing, reduce and repeat operation and the wasting of resources, be necessary the apparatus for baking of swing chute is improved.
The utility model content
The technical problems to be solved in the utility model provides a kind of basic roaster that is used for blast furnace swing chute liner uniformly that is heated of each position of chute liner mould material in the bake process that makes.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: its baking pipe and conduit by U-shaped is formed; The one side of described baking pipe is evenly distributed with flame hole along the center line of pipe, and two mouths of pipe at baking pipe top all seal; The bottom of described baking pipe is communicated with conduit.
Two end tops of baking pipe described in the utility model all are connected with fixed hook; The bending direction of described fixed hook and the flame hole of baking on the pipe are towards consistent.
The beneficial effect that adopts technique scheme to produce is: when baking swing chute liner, its be heated less, the heat radiation faster two end faces the utility model is installed, feed coal gas from conduit like this and light, the flame hole on the baking pipe jets out flames and can obviously improve the temperature of chute liner end face; Because flame hole evenly distributes, it is even substantially that each position of chute liner mould material is heated, thereby effectively avoid because of the inhomogeneous situation that causes the chute liner crackle, crack, damage to occur of being heated.The utility model is simple in structure, and effect is obvious, effectively reduces swing chute liner because of the baking inhomogeneous probability of scrapping that is heated, and can also the refractory materials of other U-shaped structure be toasted.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Among the figure: baking pipe-1, flame hole-2, conduit-3, fixed hook-4.
Embodiment
Fig. 1, shown in Figure 2, this roaster that is used for blast furnace swing chute liner is made up of baking pipe 1, conduit 3 and fixed hook 4, and baking pipe 1 and conduit 3 are hollow steel tube and make.Described baking pipe 1 becomes " U " type by simmering and bending, and the one side of baking pipe 1 is evenly equipped with flame hole 2 along the tube wall center line of pipe, and two mouths of pipe in baking pipe 1 top are all dead with round plate shutoff weldering, avoid coal gas to discharge from the mouth of pipe, influence cured effect.
Shown in Figure 1, the described conduit 3 of this roaster is straight-through steel pipe, is the passage of coal gas being introduced baking pipe 1.Perforate under the bottom, axis of baking pipe 1 vertically is placed on conduit 3 position of opening and is welded into one with baking pipe 1.The latus rectum of conduit 3 is slightly less than the latus rectum of baking pipe 1, can fully burn so that enter the coal gas of baking pipe 1, avoids remaining coal gas to leak outside and causes environmental pollution.
Shown in Fig. 1,2, the described baking of this roaster is managed 1 two end tops fixed hook 4 is installed, and effect is fixing and supports U-shaped roaster.Described fixed hook 4 is made for wire rod or round steel bending, and totally 2, profile "
" shape, the shackle legs of fixed hook 4 is overlapped on baking pipe 1 top outer and is welded into one, the clevis arm of fixed hook 4 and baking manage set flame hole 2 on 1 towards consistent, the hook of fixed hook 4 is parallel with shackle legs and be in the same plane.
When this roaster uses, the baking pipe is provided with the one side of flame hole towards swing chute liner end face, the horizontal-arm of fixed hook is placed on the chute liner upper surface, adjust flame hole on the baking pipe apart from about the chute liner end face 10mm, hook with fixed hook embeds, is stuck in chute liner upper surface then, thereby U-shaped roaster is fixed on the end face at swing chute two.After this roaster fixes, feed coal gas from conduit and light, the flame hole on the baking pipe jets out flames, and finishes the baking to chute lining end face.
