Abstract
The present invention relates to treating method of metallurgical slag, and is especially treating method of high viscosity metallurgical slag. The treating method of high viscosity metallurgical slag includes initially dispersing the high temperature melting state metallurgical slag in a high speed rotating pelletizing roller, throwing to rotating drum filled with cooling steel balls for further pelletizing, crushing and cooling, further cooling the pelletized slag in the outer cylinder, and exhausting the slag. The treating method can obtain metallurgical slag in proper temperature and high safety, and has little balls in the drum, easy apparatus maintenance, low power consumption and stable running.
Description
(1) technical field
The present invention relates to the treatment process of metallurgical slag, relate in particular to the treatment process of high viscosity metallurgical smelting slag.
(2) background technology
The developing direction of modern metallurgical slag treatment technology is short flow process, resource utilization, cleans.Existing drum process metallurgical cinder treatment technology, the squirrel-cage cylinder of dress steel ball in adopting, as cooling body bits are carried out chilling and fragmentation by the steel ball that rolls, owing to need to adopt the steel ball of tens tons of rollings, therefore energy consumption is bigger, and facility investment is also bigger, and maintenance is higher relatively, this technology has the tapping temperature height when handling the high viscosity slag in addition, easily rings quick-fried shortcoming.Independent employing runner granulation is also arranged or adopt the cylinder granulation that slag is handled separately; slag to good fluidity is fine; but the slag to the flowability difference is single owing to the granulation means; the granulation link is few; granulation intensity is low, and the agglomerate slag is difficult to be disperseed, and big slag is rolled into a ball the phenomenon that just is easy to produce cinder ladle water when entering the spray district like this; blast, influence ordinary production and device security.
(3) summary of the invention
The object of the present invention is to provide a kind of treatment process of high viscosity metallurgical smelting slag; this treatment process adopts the technological thought of the hot first granulation postcooling of slag; the high viscosity slag is handled; overcome the defective that prior art adopts steel ball that slag is handled separately, made tapping temperature suitable, device security is good; the cylinder ball loadings is few; maintenance of the equipment is convenient, and power consumption is few, and is stable.
The present invention is achieved in that a kind of treatment process of high viscosity metallurgical smelting slag; it is characterized in that high temperature melt slag directly is poured on the granulation roller of high speed rotating and tentatively disperseed, thrown after the granulation and deliver in the swing roller; be full of the steel ball cooling body in the cylinder to the further granulation of slag, fragmentation and cooling; the cooled granulated slag of fragmentation is flowed out to enter in the outer cylinder body by the grid section gap of inner barrel and cools off, and then the discharge outer cylinder body obtains the finished product slag.
The present invention adopts metallurgical cinder after hot first granulation; mix the technological thought that carries out fragmentation and cooling process with the steel ball that rolls again; make the high viscosity slag become small dreg piece down easilier from the bulk slag hot; mix by fragmentation with steel ball again; and by the spray water cooling, slag becomes satisfactory finished product slag under rolling steel balls is ground like this.For flowability slag treatment preferably, also equally carry out, and treatment effect can be better.Treatment process of the present invention has overcome effectively not only that prior art adopts steel ball that slag is handled separately to cause that the steel ball number is many, slag easily rings quick-fried defective, and the finished product slag temperature that obtains is suitable, and security is good, the cylinder ball loadings is few, maintenance of the equipment is convenient, and power consumption is few, and is stable.
(4) description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the apparatus structure synoptic diagram of the treatment process of enforcement high viscosity metallurgical smelting slag of the present invention.
Among the figure: 1 granulation wheel apparatus, 2 loading hopper devices, 3 drum apparatus, 4 cylinder backing rings, 5 cylinder transmission bull gears, 6 vapor discharge channels, 7 riding wheel apparatus, 8 discharge of wastewater grooves, 9 discharge chutes, 10 steel balls.
(5) embodiment
Referring to Fig. 1; directly be poured on metallurgical cinder (as slag) on the granulation wheel 1 of high speed rotating through loading hopper 2; disperseed rapidly by granulation wheel 1; cutting also leaves to the cylinder 3 that rotates; because the steel ball 10 in the cylinder 3 is the state of leaving; enter slag and steel ball 10 thorough mixing and the fragmentation of cylinder 3; sharply cooled off by steel ball 10 and the water coolant that is loaded on the shower ejection on the cylinder 3 simultaneously; the granulated slag of cooling after the fragmentation spilt by the inner barrel grid section gap of cylinder 3 and enters outer layer barrel; because the water that has inner barrel to flow down in the outer layer barrel; slag is cooled off in outer layer barrel for the second time; when slag is transported to grid flight place with water; have only a slag to be raised the top that is transported to discharge chute 9 and fall into discharge chute 9; discharge outside the barrel 3; waste water flows out from the gap between cylindrical shell 3 and the vapor discharge channel 6 vertically in the bottom of blanking district cylinder 3; enter waste water chute 8, the steam that process produces is discharged by vapor discharge channel 6.
Claims (1)
1. the treatment process of a high viscosity metallurgical smelting slag; it is characterized in that high temperature melt slag directly is poured on the granulation roller of high speed rotating and tentatively disperseed, thrown after the granulation and deliver in the swing roller; be full of the steel ball cooling body in the cylinder to the further granulation of slag, fragmentation and cooling; the cooled granulated slag of fragmentation is flowed out to enter in the outer cylinder body by the grid section gap of inner barrel and cools off, and then the discharge outer cylinder body obtains the finished product slag.
