Abstract
The utility model discloses a consteel electric furnace ash discharging mechanism, which comprises a first ash discharging port (1) and a second ash discharging port (2). The first ash discharging port (1) is located at the joint position between a feeding section of the consteel electric furnace and a plate E, and the second ash discharging port (2) is located at the joint position between the plate E and a plate D of the consteel electric furnace. An ash catching hopper (3) is respectively installed on the first ash discharging port (1) and the second ash discharging port (2). Gaps are arranged at the joint position between the plate E and the feeding section of the consteel electric furnace and the joint position between the plate E and the plate D of the consteel electric furnace, thereby being capable of effectively removing a large quantity of dusts and sand and stones contained in steel scraps, improving recovery rate of the steel scraps, shortening smelting time, reducing smelting cost, and ensuring product quality.
Description
Technical field
The utility model relates to a kind of Kang Sidi electric furnace ash exhauster, belongs to metallurgical technology field.
Background technology
Kang Sidi electric furnace (CONSTEEL) is a kind of advanced electric steelmaking process that adopts furnace charge feeding continuously, continuously pre-heating and smelt continuously.It is low that it not only has a melting electric consumption, short and the flexible and controllable (40～60min) of smelting cycle, the characteristics that production efficiency is high, and noise in workshop is lower when smelting, only when each production cycle begins, utilize the crane of ladle handling to adorn steel scrap once, be used for the formation in the initial molten bath of the first stove production, just do not need crane to carry out basket charging then, do not had diffusing of reinforced flue gas of material basket and dust, working environment is greatly improved.
Kang Sidi electric furnace (CONSTEEL) is when reinforced, and steel scrap directly installs to the furnace charge conveyer by the steel scrap field, and conveyer divides two sections of feeding section conveyer and preheating section conveyers.Highly certain steel scrap moves on to preheating section from feeding section uniformly, and steel scrap is with the smoke pre-heating that electric furnace comes, and movably connects the steel scrap of dolly after with preheating and joins the electric furnace from preheating section.Steel scrap is the important raw and processed materials of smelting iron and steel, wherein often contains a large amount of dust and sandstone, the impurity that these are useless, prolonged the duration of heat, increased smelting cost, these impurity of online removal how guarantee that product quality is that we want the problem that solves always.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of Kang Sidi electric furnace ash exhauster that can effectively remove undesired impurities such as dust in the steel scrap and sandstone, thereby overcomes above-mentioned the deficiencies in the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of Kang Sidi electric furnace ash exhauster, its formation mainly comprises first ash discharging hole and second ash discharging hole, described first ash discharging hole is positioned at the feeding section and the E dish seam crossing of Kang Sidi electric furnace, and second ash discharging hole is positioned at the E dish and D dish seam crossing of Kang Sidi electric furnace; Below first ash discharging hole and second ash discharging hole, be equipped with and connect ash bucket.
In the above-mentioned Kang Sidi electric furnace ash exhauster, the A/F of described first ash discharging hole and second ash discharging hole is 20～30mm.
In the aforesaid Kang Sidi electric furnace ash exhauster, be provided with belt conveyor below connecing ash bucket described.
Beneficial effect: compared with prior art, the E dish that the utility model coils seam crossing and Kang Sidi electric furnace by feeding section and E at the Kang Sidi electric furnace cracks with D dish seam crossing ash discharging hole is set, can effectively get rid of a large amount of dust and the sandstone that contain in the steel scrap, thereby improve the steel scrap rate of recovery, shorten the heat, reduce smelting cost, guarantee product quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-first ash discharging hole, 2-second ash discharging hole, 3-connects ash bucket, 4-belt conveyor, 5-feeding section, 6-preheating section, 7-dynamic seal (packing), 8-electric furnace, 9-Kang Sidi driver.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
The specific embodiment
Embodiment 1.As shown in Figure 1, comprise that first ash discharging hole 1, second ash discharging hole, 2, the first ash discharging holes 1 are positioned at the feeding section and the E dish seam crossing of Kang Sidi electric furnace, second ash discharging hole 2 is positioned at the E dish and D dish seam crossing of Kang Sidi electric furnace; Below first ash discharging hole 1 and second ash discharging hole 2, all be equipped with and connect dust and the sandstone that ash bucket 3 is used for collecting steel scrap.The A/F of first ash discharging hole 1 and second ash discharging hole 2 is (to determine according to material) about 25mm.Connect ash bucket 3 below be provided with belt conveyor 4.
During making, respectively open a seam about 25mm at the feeding section of Kang Sidi electric furnace and E dish seam crossing and E dish with D dish seam crossing, obtain first ash discharging hole 1 and second ash discharging hole 2, on first ash discharging hole 1 and second ash discharging hole 2, respectively install one and connect ash bucket 3, the below that connects ash bucket 3 is provided with belt conveyor 4, and dust that leaks down in the seam with handle such as belt conveyor 4 and conveying pipelines and sandstone are discharged to prepare burden to stride and get final product.
Embodiment of the present utility model is not limited to the foregoing description, all belongs within the protection domain of the present utility model in the various variations of making under the prerequisite that does not break away from the utility model aim.
Claims (3)
