Abstract
An isolator used for stainless steel slag recovery processing comprises at least two clapboards and at least one groove is formed on both the clapboards. The clapboards are crossed, embedded and connected with each other through the grooves; drop hangers are arranged on the clapboards; two end sides of the clapboards are matched with the inner wall shape of a slag basin. When adopting the isolator of the utility model to hold hot stainless steel slag, the size of waste steel in the steel slag after cooling processing can meet the requirement for feeding a electrical furnace, thereby reducing the consumption caused by cutting the large-sized waste steel, increasing the recovery rate and the utilization rate of the waste steel, avoiding secondary pollution to environment by cutting, and reducing the labor intensity by eliminating the middle step of cutting the large-sized waste steel; at the same time, during the process of cooling, due to the distinct increase of natural-produced cracks on the steel slag in the slag basin after the using of the isolator, the cooling speed of the steel slag is picked up, the spraying time is reduced, the velocity is increased, and the spraying water consumption is reduced synchronously so as to save the water resource.
Description
Technical field
The utility model relates to a kind of slag steel recovery method, particularly a kind of shield retaining that is used for the recycling of stainless steel slag steel.
Background technology
The treatment process of stainless steel smelting slag is normally used the stainless steel slag of slag ladle splendid attire heat in the prior art, is transported to open-air cooling field, and air cooling+spray soaks cooling, turns over the treatment process of slag then.
The applicant proposed the treatment process of a kind of stainless steel smelting slag of number of patent application 200710042556.7 in 2007, it comprises air cooling, and---spray soaks cooling---turns over three processing steps of slag, compare the treatment process of existing stainless steel slag, owing to before spray soaks cooling step, added the air cooling step, the heat energy of high-temperature liquid state slag has evenly been discharged, thereby effectively reduce the generation of the quick-fried accident of spray, and slag cooling contraction produces be full of cracks, makes second step spray immersion refrigerative effect better.Spray soaks uninterrupted earlier water spray in the cooling step, is interrupted spray again and leaves standstill thermometric, has guaranteed the slag cooling performance, can effectively prevent still there is the liquid state slag in the slag ladle, thereby avoids meeting water when turning over slag and spray quick-fried.
And in connecing the slag process, slag contains a large amount of molten steel, and average every jar reaches 3-5T.Through after the cooling process, this part steel scrap size conforms to the inwall size of slag ladle, greater than steelworks electric furnace charging ability.Therefore, the steel scrap of this part bulk must step such as cut through burning, make steel scrap reach the size of electric furnace charging requirement, could utilize once more, and cut in the process in burning, have 17% steel scrap amount to be depleted, it is very big to the influence of environment to produce a large amount of toxic smogs simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of shield retaining that is used for the recycling of stainless steel slag steel, the control slag ladle connects and discards the volume that molten steel is formed the slag piece in the slag process in the jar on the source, reduce the steel scrap burning and cut loss, reduce pollution, improve the utilization ratio of stainless steel raw scrap material environment.
For achieving the above object, the technical solution of the utility model is:
A kind of shield retaining that is used for stainless steel slag steel recycling is placed in the slag ladle that collects stainless steel smelting slag, and it comprises, at least two dividing plates have a groove respectively at least on this dividing plate, and described two dividing plates intersect buckle mutually with this groove and connect.
Again, described at least two dividing plates are latticed connection.
The mutual square crossing of described at least two dividing plates connects.
In addition, described dividing plate is provided with suspension hook.
Described dividing plate both end sides and slag ladle inner wall shape are complementary.
The utility model shield retaining is placed in the stainless steel smelting slag of splendid attire heat in the slag ladle, overturning stainless steel smelting slag wherein is to stack up yard after the process cooling process, utilize the pneumatic pick machine to carry out broken apart according to the slit that separator plates produces, so that the steel scrap size that produces satisfies the requirement of electric furnace charging, reduce the heavy scrap burning and cut loss.
The beneficial effects of the utility model are:
After using shield retaining to collect the stainless steel slag of heat, through contained steel scrap size in the slag of cooling process, can satisfy the requirement of electric furnace charging, reduce heavy scrap and cut the loss that produces because of burning, the recovery rate and the utilization ratio of steel scrap have been improved, and stopped to burn and cut in the process second environmental pollution, remove heavy scrap from and burnt the middle-chain of cutting processing, alleviated labour intensity.In process of cooling, because after using shield retaining, the spontaneous crack of slag obviously increases in the slag ladle, has accelerated the speed of cooling of slag, spray cooling time decreased improved the turnover rate of slag ladle about 8 hours simultaneously, and water spray reduces nearly 4m synchronously
3, saved water resources.
Description of drawings
Fig. 1 is the user mode synoptic diagram of the utility model one embodiment;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3, Fig. 4 are two kinds of structural representations of the utility model dividing plate.
Embodiment
Referring to Fig. 1～Fig. 4, the utility model is used for an embodiment of the shield retaining of stainless steel slag steel recycling, be placed in the slag ladle that collects stainless steel smelting slag, it comprises, six dividing plates 1,2, have three grooves 11,21 on this dividing plate 1,2, described six dividing plates 1,2 are latticed, square crossing connection with the intersection buckle connection mutually of this groove 11,21; Dividing plate 1,2 is provided with suspension hook 3,3 '; Dividing plate 1,2 both end sides and slag ladle 4 inner wall shape are complementary.
Stainless steel slag with the slag ladle splendid attire heat that the utility model shield retaining has been installed, handling is to open-air cooling field, rest on naturally cooling in the air, behind 20 hours air coolings, beginning discontinuous measurement tank wall temperature, when the tank skin top temperature is 170 ℃ or more during low temperature, with spraying the uninterruptedly direct spray water in the surface of the slag in slag ladle of hydraulic giant, to accelerate the cooling of warm sludge, regularly measure tank wall temperature, until the tank skin top temperature is 110 ℃ or more during low temperature, slag ladle is transported to the stainless steel slag stack up yard, and overturning stainless steel smelting slag wherein uses the pneumatic pick machine slag of turning down to be carried out the letter sorting of steel scrap to stack up yard, the steel scrap that sorts out returns electric furnace material lattice, as the electric furnace charging raw material for standby.This process, having reduced the heavy scrap that produces in the former stainless steel smelting slag treating processes needs to cut to reach the middle-chain that the electric furnace charging size just can be used through special burning earlier, alleviated labour intensity, reduced steel scrap and burnt and cut caused 17% steel scrap loss, stopped steel scrap simultaneously and burnt and cut in the process second environmental pollution.
In sum, before connecing slag, settles by slag ladle the utility model shield retaining earlier, so that the high-temperature liquid state slag that collects is evenly isolated, through after the cooling process, can effectively sort the stainless steel steel scrap, solve the difficult problem that the stainless steel steel scrap needs special cutting, drops hammer, can directly return steelworks and use, thereby avoid repeated pollution, reducing cost reduces labor intensity.
