The other side, the spray gun area of the reduction furnace bottom is provided with spray gun, and the liner of the reduction furnace bottom is in one after building by laying bricks or stones
Plane, restore furnace bottom thickness of inner lining be 70cm, the siphon build by laying bricks or stones after directly be connected in reduction furnace, the spray gun goes out
Mouth is flushed with the liner of reduction furnace bottom, and building by laying bricks or stones for the liner carries out from the bottom to top in reduction furnace, the block of the liner
Building method is：a：Liner lower portion takes the fissure of displacement to build by laying bricks or stones, after spray gun area indwelling dilatation joint, inside lining building half, makes arch
Mould accomplishes fluently support；b：Liner top half takes the fissure of displacement to build by laying bricks or stones, fills in filler material, when building by laying bricks or stones to fore shaft brick, need to process in advance
Fore shaft brick after fore shaft brick masonry is complete, is reinforced using 2 ~ 3mm steel plates and is locked, and ball collar broken end is built using flat, reserves expansion
Seam.
Further, refractory material used is built by laying bricks or stones by weight percentage at the top of the charge door, slag notch and liner：
0.7% SiO2, 0.9% CaO, 8% Fe2O3, 19% Cr2O3, 67% MgO, remaining is impurity, all components weight percent
The sum of number is 100%, and the floss hole, siphon, spray gun area and liner middle part, bottom build refractory material used by laying bricks or stones by weight
Percentages：0.8% SiO2, 0.8% CaO, 13% Fe2O3, 21% Cr2O3, 56.5% MgO, remaining is impurity, is owned
The sum of component weight percentage is 100%.
Further, the dilatation joint uses the yellow plate paper of 3mm thickness.
Further, the charge door has 1 ~ 2.
Further, the spray gun at least five arrange in spray gun area in single straight line.
A kind of building method of reduction inner lining of furnace, advantage are：
1. the bottom lining after method using the present invention is built by laying bricks or stones is in a plane, reduce the application of filler, convenient for more
When changing spray gun, shortens activity duration nearly 3 hours, improve operating efficiency；
2. method using the present invention build by laying bricks or stones rear siphon directly be connected in stove, when siphon blocks, can directly burn
It is logical, blowing out is avoided, the activity duration has been saved；
3. the refractory material that the present invention uses reduces iron-holder compared to common refractory material, chromium content is improved, from
And the probability that reduction reaction occurs in reduction furnace for the ferro element in refractory material is reduced, improve the service life of refractory material；
4. after method using the present invention and refractory material laying, bottom spraying gun tuyere area liner by overhaul in 1 year, 6 months
Light maintenance is extended for overhaul in 2 years, light maintenance in 1 year, and the reduction inner lining of furnace service life reaches 2 years or more, saves reduction furnace maintenance cost, energy
Higher economic benefit is brought for enterprise, good base has been established in the popularization that technique is also reduced directly for the liquid slag of a new generation
Plinth.
