Abstract
The utility model relates to a device for producing nodule iron, which comprises a granulation tank, an iron outlet pipe, an iron outlet spray head and a condensing chamber, wherein, a fireproofing material layer is built in the wall of the granulation tank. The upper part of the granulation tank is provided with an iron inlet and the bottom is communicated with one end of the iron outlet pipe, and the other end of the iron outlet pipe is connected with the iron outlet spray head. The upper part of the granulation tank is communicated with a high pressure air pipe. The condensing chamber is arranged on the lower side of the iron outlet spray head and a water nozzle is arranged in the condensing chamber. Molten iron flow which is ejected out from the iron outlet spray head is solidified into nodule iron under the function of water mist which is sprayed by the water, and the nodule iron is gradually cooled down in the process of falling. The utility model has the advantages of effective control of granularity, uniform granularity, good smoothness, low iron loss, great improvement of yield and environmental pollution reduction.
Description
The utility model relates to a kind ofly makes motlten metal be solidified into the device of particle with physical method, particularly produces the device of granular iron.
Granulated iron is the granular iron of being made by the molten iron of blast furnace process.Granulated iron behind decarbonization process can become the substitute of steel scrap, is a kind of electric-arc furnace steelmaking raw material of high-quality.Existing granulated iron production does not generally have special equipment, and molten iron flows into along trough in the high pressure tank that is located at below the platform, is washed away after broken by water under high pressure is quick-fried.The granulated iron granularity of producing is inhomogeneous, does not meet quality requirement.The excessive decarburization quality that influences postorder of granularity, undersized is then owing to the gas permeability difference influences metallurgical effect.Simultaneously, because no suitable special equipment, granulated iron output is restricted, and environmental pollution is serious.
The utility model purpose is to overcome above-mentioned shortcoming of the prior art and a kind of device of producing granulated iron is provided, and makes it to produce even-grained granulated iron, improves granulated iron output simultaneously, reduces environmental pollution.
The utility model purpose is achieved by the following technical solution:
The utility model comprises the granulation jar in forming, goes out iron pipe, the shower nozzle that taps a blast furnace, condensation chamber, builds refractory masses in the granulation tank skin, and its top is provided with into Tie Kou, and the bottom communicates with going out iron pipe, goes out the other end of iron pipe and the shower nozzle that taps a blast furnace joins.Granulation jar top communicates with high-pressure air pipe.Condensation chamber is positioned at the preceding downside of the shower nozzle that taps a blast furnace, and is provided with water nozzle in it.The molten iron stream that penetrates from the shower nozzle that taps a blast furnace is frozen into spherical granulated iron and cooling gradually in dropping process under the effect of water smoke that water nozzle sprays.
The device of above-mentioned production granulated iron, described condensation chamber are tubular structure, and water nozzle is located on the condensation chamber inwall, and outlet is inclined upwardly.
The device of above-mentioned production granulated iron, the described shower nozzle that taps a blast furnace is provided with 3--9 spray orifice.
The device of above-mentioned production granulated iron, described granulation jar is provided with vent valve and Pressure gauge.
Use the utility model is produced granular iron, can effectively control granularity by the size of adjusting hole on the pressure in the granulation jar and the shower nozzle that taps a blast furnace, and product is spherical; epigranular, fineness are good; iron loss is extremely low, can increase substantially product quality and output, reduces environmental pollution.
Fig. 1 is the structural representation of the utility model embodiment.
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment:
The utility model comprises granulation jar 1 in forming, goes out iron pipe 2, the shower nozzle 3 that taps a blast furnace, condensation chamber 4; build refractory masses 5 in the strong smile wall of grain, its top is provided with into iron mouth 6, the bottom with go out iron pipe 2 and communicate; the other end that goes out iron pipe 2 joins with the shower nozzle 3 that taps a blast furnace, and evenly is provided with 3 spray orifices 9 on the shower nozzle that taps a blast furnace.Granulation jar 1 top communicates with high-pressure air pipe 7, so that fill high-pressure inert gas in granulation jar 1.Condensation chamber 4 is a upper and lower mouthful of barrel-like structure that opens wide, and is positioned at the orientation, whereabouts of tap a blast furnace shower nozzle 3 preceding downsides, molten iron, and its inwall is provided with outlet and is inclined upwardly 30 °--60 ° water nozzle 8.Flow into granulation jar 1 from trough through going into iron mouth 6 through pretreated molten iron, the iron pipe 2 of flowing through out again penetrates from the shower nozzle 3 that taps a blast furnace.This molten iron stream sprays under the effect of water smoke at water nozzle 8, is frozen into granulated iron and cooling gradually in dropping process, falls via the condensation chamber end opening.
Because the granularity of granulated iron and the pressure in the granulation jar are inversely proportional to, so can be by adjusting the pressure control granularity in the granulation jar.For ease of accurately grasping and adjusting a jar internal pressure, vent valve 10 and Pressure gauge 11 are housed on high-pressure air pipe 7.
