Abstract
The utility model discloses a preinstalled jet nozzle for the bottom gun of the heat exchange rotating furnace. The utility model has the advantages of simple structure and convenient operation and can be effectively used for changing the bottom gun of the rotating furnace in the heat state to successfully solve the problem that the bottom gun of the rotating furnace is not synchronous with the service life of the furnace. Meanwhile, the utility model can also be used for the melting technologies of bottom blowing, side blowing and steel bag bottom blowing the argon and the service life of the furnace can be improved by changing the spray gun in the heat state.
Description
The utility model relates to giving of a kind of converter bottom and establishes nozzle, and particularly giving of rifle established nozzle at the bottom of changing top and bottom combined blown converter under the hot state.
At present, converter top bottom blowing technology is in vogue, but can not be synchronous with it because the end rifle life-span of converter often is lower than furnace life, many producers have to change top blast into and smelt after rifle is scrapped at the bottom of the converter, thereby have influenced the performance of the various superiority of combined blown converter.
Learn that by retrieval the patent documentation spy opens clear 57-73112 and discloses a kind of top bottom blowing bottom nozzle installation method and installed and establish nozzle with giving.This gives establishes nozzle and is mainly used in cold conditions to be installed the end and prevents the end rifle damage during rifle.And be used for hotly changing giving of rifle and establishing the nozzle arrangements complexity, operation inconvenience, and owing to stretch into part in the stove and cross kind of meeting at converter smelting and burnt, manage fusing, outer tube and cover brick bonding in the possibility of result causes even the bleed-out phenomenon occurs, therefore when heat is changed rifle, can run into many troubles, and the possibility that can't implement is arranged.
In view of the above problems, task of the present utility model provide a kind of simple in structure, easy to operate, can be used for effectively heat change combined blown converter at the bottom of giving of rifle establish nozzle, by change rifle solve the end rifle life-span can not with synchronous problem of furnace life.
Particular content of the present utility model is:
Other position of the furnace bottom of rifle is installed one or more giving and is established nozzle at the bottom of leaving converter.Give and establish nozzle and form by false rifle and the refractory materials sleeve pipe that is installed in the bottom brick, false rifle is made of stainless steel tube, the big nut with holes and the flange that are filled in refractory materials such as the magnesite refractory in the steel pipe and are contained in steel pipe one end, its shape, size that is contained in the inside pipe casing branch is consistent with true rifle to be changed, leave certain clearance between it and the sleeve pipe, when this gap should guarantee thermal expansion, can prevent from the gap bleed-out, can in sleeve pipe, extract false rifle easily again, in addition, false rifle is that logical flange is fixed on the steel plate of furnace hearth.
After rifle is scrapped at the bottom of the converter, can will give the false rifle of establishing in the nozzle and extract, then, will insert in the sleeve pipe at the circumscribed to be changed true rifle of finishing changing piping system of stove, and true rifle be fixed, thereby can utilize the new rifle of changing to proceed top bottom blowing by flange.
The utility model compared with prior art has following advantage:
1. simple in structure, easy to operate; Can be used for rifle at the bottom of changing converter under the hot state effectively, successfully solved the end rifle life-span can not with synchronous technical barrier of furnace life.
2. the utility model can be used for smelting technologyes such as other bottom blowing, side-blown and steel ladle bottom argon blowing, can improve stove work-ing life by hot replacing spray gun greatly.
Description of drawings:
Fig. 1 establishes the nozzle arrangements synoptic diagram about giving of rifle offside at the bottom of being installed in furnace bottom.
The 1st, false rifle, the 2nd, the refractory materials sleeve pipe, the 3rd, stainless steel tube, the 4th, magnesite refractory, the 5th, big nut with holes, the 6th, the gap between sleeve pipe 2 and the false rifle 1,7 and 8 is flanges, the 9th, bottom brick, the 10th, rifle at the bottom of the converter.
Now in conjunction with the accompanying drawings the utility model is described in detail as follows:
Give and establish nozzle installing one with the symmetrical position of rifle at the bottom of the converter 10, this gives establishes nozzle by false rifle 1 and give the magnesium carbon refractory sleeve pipes 2 that are embedded in the bottom brick 9 and form.False rifle 1 by stainless steel tube 3, be filled in the steel pipe 3
Water magnesia 4, big nut with holes 5 and the flange 8 that is welded on the steel pipe 3 constitute; Partial shape, size that false rifle 1 inserts sleeve pipe 2 are consistent with true rifle to be changed; 1～2mm is got in gap between false rifle 1 and the sleeve pipe 2; False rifle 1 is fixing by the flange on flange 8 and the steel plate of furnace hearth 7.
After rifle at the bottom of the converter 10 is scrapped, the tapping slagging is also tumbled converter to going out the top of the slag, insert in the hole of big nut 5 (diameter in hole is about 16mm) with the rod iron about a φ 12mm and after removing the flange constraint, rotate false rifle 1, then by hand or chain block extract false rifle 1.
After false rifle 1 is pulled out, will insert in the sleeve pipe 2, and, so far, change rifle and finish by the fixing true rifle of flange at the circumscribed to be changed true rifle of finishing changing piping system of stove.
Claims (2)
1, a kind of be used for heat and change combined blown converter at the bottom of giving of rifle establish nozzle, it is characterized in that giving and establish nozzle and form by false rifle 1 and the refractory materials sleeve pipes 2 that are installed in the bottom brick 9, false rifle 1 by stainless steel tube 3, be filled in the magnesite refractory 4 in the steel pipe 3, the big nut with holes 5 and the flange 8 that are contained in steel pipe 3 one ends constitute, false rifle 1 is consistent with the shape and size and the true rifle to be changed of the mating part of sleeve pipe 2, false rifle 1 leaves certain clearance 6 with sleeve pipe 2, and false rifle 1 is fixed on the steel plate of furnace hearth by flange 7 and flange 8.
2, establish nozzle according to giving of claim 1, it is characterized in that this nozzle the different positions of furnace bottom give establish one or more.
