Therefore, if the hot steel slag at this high temperature is to be stabilized, it must be performed on the hot steel slag first. Only before the pre-treatment operation can the hot steel be placed in the hot-seal device. The above-mentioned pre-operation method is shown in @ 1. 5 It mainly includes the collection step w 1G, the ground splashing step, and the first time. Water spray cooling step 14, slag stacking step 16 and water spray cooling step 18, etc .; Among them, the 6th aggregate step 10 is to crush the remaining high-temperature steel after the steelmaking, and use the large slag bucket to hold it. For the purpose of carrying and conveying, and at the same time, a large meeting area is provided for the heating steel to cool down in spare time to facilitate the subsequent processing of the hot steel slag. Therefore, the large slag bucket is filled with Xixigu i A 丄. Awen heats the steel slag and carries it to the slag dumping area, that is, 10 for hot ship splashing ㈣12, directly stack the hot __ in the inverted site. Still continue the aforementioned 'Later for the stacked hot steel slag' for the first time water spray cooling (that is, the water spray cooling step ⑷), in order to cool the high temperature heat ㈣ first with water cooling 'When the temperature of the hot slag surface has fallen to a low level, c, then proceed to stack clearing step 15 step 16, that is, use a slag pusher to concentrate the hot steel slag stack at the-place Γ 空 and leave it to the site to do For the current hot steel slag pouring and cooling treatment approved by Ma Jiujiu, a second water spray cooling (18) is performed at the end, so that the hot water of the stack is sprayed with water again. However, after reaching 100 50 c, the cooled hot steel can be sent to Processing Wei is directly used, but because the hot steel has insufficient stability and does not meet the requirements of 20 in actual use, it has been further stabilized for the hot steel slag. However, the hot steel slag has been carried out for the previous demolition. In the previous processing operation, it was found that the following defects are worth improving: (1) Caused the air pollution problem: Because the high-temperature hot steel slag was liquid and poured directly on the ground of the slagging area in a splashing manner, and reused water spray Way, add water cooling cracking into 5 1225098 block, for subsequent transportation; however, the slag pile of hot steel slag after spray cooling cooling is easy to produce dust and air pollution, which leads to the lack of air pollution. It is very easy to cause public grievance for the rising awareness of environmental protection. Therefore, the pre-treatment operation needs to be improved urgently. 5 (2) There is a gas explosion safety problem: It is known that the large slag bucket has a capacity of 42 tons per barrel, so when such a large amount of hot steel slag is directly poured into the slag dumping area in a pouring manner. On the ground, due to the effect of repeated water spraying and slag stacking on the hot steel slag, the site is likely to be a tide seat or a state of standing water. Once a large amount of high temperature hot steel slag is covered with water °, it will quickly The water material is vaporized into steam, and then the production line explodes. At this time, the staff does not pay attention to it. 'It will be injured by the gas explosion. It will also cause damage due to the collapse of the equipment. Therefore, industrial safety incidents are frequent. (3) The subsequent stabilization process is slow and costly: It is known to perform the pre-treatment operation for hot steel slag, and finally, after cooling 5 hot steel and 2 water to _ ~ ah, then send it to the hot decanting process. However, since the hot steel rupture has been cooled down by water, the subsequent stabilization treatment operation to be carried out must be supplemented and improved with the use of large slab gas to provide the hot steel slag in the hot stuffing device. Stabilizing the operating temperature, it must consume a lot of steam thermal energy to maintain at a fixed temperature and pressure, which is not economically beneficial. (4) The slag pusher is severely damaged ... When the stacking step 16 was performed, the block heat_carrying stack was concentrated in the-place by the push car, and the block heat_ temperature was still as high as l〇 (MGG ° C 'Therefore, high temperature is likely to cause damage to the produced car 6 1225098. (5) Poor working environment: 5 Due to the conventional pre-treatment treatment for hot steel slag, the aforementioned air pollution and transfer will occur. Work safety and other issues, and the operator must always: work under high temperature environment, so the overall health environment is inferior to the operator. Tian Xin [Summary of the Invention] 10 Therefore, the object of the present invention is to provide a method to reduce air pollution. And gas explosion safety factors, as well as improving the quality of the operating environment, further provides a fast and low cost hot steel slag stabilization pre-treatment method for subsequent stabilization. 15 The hot steel smash pre-treatment method of the present invention is used for The pre-operation of the hot steel slag before the thermal steam curing and stabilization treatment includes an aggregate in sequence: a step, a -packing step, an air cooling step, and a demolding step. The aggregate step is to first convert the converter Steelmaking process The generated hot steel slag is collected in a large slag bucket. The dispensing step is to feed the hot steel slag in the large bucket into a plurality of fishing plates, and the air cooling step is to hot steel slag in each slag tray Perform air cooling to the surface temperature of 35 (TC below; this demolding step is to complete the completed air cooling step: 20 hot steel slag is removed from the rupture plate to form slag, and the removed slag is cooled to the heart from autumn The temperature is 500 ° C ~ 700 ° C. According to the present invention, the hot steel slag is sent from the ground to the stabilizing prince through the above steps, the material falls to the ground and the slag truck is used for slag stacking, and the hot Z slag treatment process is even less. Water spray cooling is required, so the quality of the working environment is improved. ", And there is no air explosion, industrial safety and air pollution problems. At the same time, it can reduce the damage of the slag pusher and the damage of the machine 7 5. Moreover, the core temperature of the hot steel slag finally removed can reach 5 〇〇〇c, the follow-up hot steam curing and stabilization treatment as the heat energy required by # can be provided by the slag, which can greatly reduce the heat required for mosquitoization operations, and the cost and cost of treatment operations.-[Implementation mode ] In the foregoing and other technologies related to the present invention , Characteristics and effects, in the detailed description of the preferred embodiment of the McCoy pattern with the mouth, will understand the main. 10 Read Figure 2, one of the hot steel slag pretreatment method of the present invention is better This embodiment is used for the pre-operation of hot steel slag before the thermal steam curing and stabilization treatment. The hot-steel crushing method of the front part of the method includes sequentially an aggregate step 2, a packing step 3, and an air cooling step. 4. And a demolding step 5. 15 In the aggregate step 2, this embodiment is based on the converter steel slag. The worker first collects the hot steel produced by the converter steelmaking process. And each big slag bucket can hold about 42 tons of hot steel slag. Among them, the hot steel slag is in a liquid state and its temperature is between 1200 and 1400 ° C due to the time of containing the hot slag bucket . 20 In step 3 of this sub-step, the hot steel slag in the large slag bucket is repacked into a plurality of slag trays, and a mold release agent must be applied before each slag tray is filled to facilitate hot steel slag hardening. In the demoulding operation, in addition, the hot steel slag is separately packed on the slag tray, so the hot steel slag on each slag tray can be maintained to have a specific size, size and weight. In the air-cooling step 4, the hot steel slag in each slag pan is air-cooled and cooled to reduce the surface temperature of the hot steel slag to 35 ° t: the following, and the hot steel 8? The surface of the hot steel method stacked in the tray is cooled to form a block. In the demolding step 5, the hot steel slag that has completed the air cooling step is transported to the Andinghua treatment plant one by one. The hot steel clear heart temperature is 50 (TC ~ 70 (rc), and then the hot steel slag that is block-shaped and from the lack of cold part is taken out from each plate, and placed directly in the hot stuffing device (not shown in the figure) ), In order to perform the stabilizing treatment of hot steam health maintenance after the performance. Through the above steps, the hot steel slag does not fall to the ground during the process of sending out to the stabilization process, and does not need to use a slag pusher to carry out slag stacking. Therefore, the quality of the working environment can be improved in 10 years, while there is no air pollution problem and the slag pusher equipment can be reduced = damage to 'more' is also because the pre-treatment process does not need to be cooled by water spraying. There is no air explosion safety problem, and the heart temperature can reach 500t due to the last block removed; ~ 70 (rc Therefore, the heat energy required for the subsequent thermal treatment steam stabilization treatment can be provided by the hot steel slag, which can greatly reduce the heat required for the stabilization operation by 15 and further reduce the cost of stabilization operation processing. Through the foregoing description, it can be concluded The following effects are detailed as follows: Φ (1) No air pollution problem: As the 咼 warm steel slag of the present invention is discharged as a liquid, it can be contained separately by 20 >> check disks, so that each-break disk can hold -^ The size and size of the hot steel edge, after the air is cooled for a period of time, the cooling and hardening heat is directly placed in the hot time (not a feature of the present invention, so it is not shown in the figure), so The hot steel slag does not fall to the ground during the whole process, nor does it need a slag pusher to carry out the stacking operation, and there is no water spray cooling to produce 9 1225098 dust, so the operating environment is neat and can effectively pollute. Ά (2 ) No gas explosion problem ... The high temperature hot steel slag of the present invention is cooled by air cooling during the entire processing process, so no hot steel is covered with water, and the water is quickly The gas explosion caused by gasification into vapor causes the workers and operating equipment to be injured or damaged by gas explosion, resulting in relatively low safety incidents. (3) The subsequent stabilization process is fast and low cost ... The temperature of the cleaned heart can be as high as $ ⑼. C ~ Che 'For the hot steel slag is subsequently placed in the hot stuffing device for hot steam curing ^ stabilization treatment' so hot steel can be used to clear the high temperature, and supplemented with Luo gas heating supplement at appropriate time ' In order to make the hot steel maintain a certain temperature and I force, the energy consumption of the hot steel slag processing process is relatively reduced, and the cost and cost is also relatively reduced. (4) The damage of the slag pusher equipment is reduced. It is not necessary to push the material to push the high-temperature hot steel into the seat, so there is no damage to the sidecar equipment. (5) The working environment is better: The present invention can effectively solve the pre-processing operation. The resulting air pollution and gas explosion safety issues, so for workers, the overall quality of the working environment is better than conventional. To sum up, the pre-treatment method for stabilizing the hot steel slag according to the present invention can effectively achieve the problems of no air pollution and gas explosion, and further improve the working ring = 10 5 muzzle. At the same time, the subsequent stabilization process has fast speed. And the cost, it can indeed achieve the purpose of the present invention. 4Effective ^ quasi X is only a preferred embodiment of the present invention, if not = to limit the scope of the implementation of the present invention, that is, what is simple according to the scope of the invention _ please patent scope and the description of the invention The equivalent changes and modifications should still fall within the scope of the patent of the present invention.
