实施例1Example 1
镍顶吹炉虹吸排渣装置的结构如图1所示，具体如下：The structure of the nickel top-blown furnace siphon slagging device is shown in Figure 1, and the details are as follows:
镍顶吹炉（1）高16500mm、直径5000mm，低镍锍排放口高度480mm，低镍锍液面高度＜900mm，熔体面高度2200mm，低镍锍排放口设置4个，渣放出口1个，虹吸排渣装置1个。Nickel top-blowing furnace (1) is 16500mm high, 5000mm in diameter, low-nickel matte discharge outlet height 480mm, low-nickel matte liquid level <900mm, melt surface height 2200mm, 4 low-nickel matte discharge outlets, 1 slag discharge outlet , 1 siphon slag discharge device.
虹吸排渣装置虹吸道（3）距顶吹炉（1）炉底中心高度1200mm，虹吸道（3）直径500mm，虹吸排渣口（4）下沿距炉底2200mm，虹吸井直径1000mm。Siphon slag removal device The height of the siphon channel (3) from the bottom center of the top blowing furnace (1) is 1200mm, the diameter of the siphon channel (3) is 500mm, the distance from the lower edge of the siphon slag discharge port (4) to the furnace bottom is 2200mm, and the diameter of the siphon well is 1000mm.
虹吸排渣装置的底排口（5）与虹吸道（3）在同一方向且中心距炉底高度一致（均为1200mm），虹吸道（3）堵塞排放不畅或虹吸井出现镍锍时，使用底排口（5）疏通。The bottom outlet (5) of the siphon slag discharge device is in the same direction as the siphon channel (3) and the center is at the same height from the bottom of the furnace (both are 1200mm). Use the bottom drain (5) to unclog.
虹吸排渣口（4）采用砖体砌筑方式，虹吸排渣出口设置倾动溜槽，倾动溜槽下方设置两条铜水套溜槽，可选择向某一条溜槽排放，另一条溜槽进行清理。The siphon slag outlet (4) adopts the brick masonry method. The siphon slag outlet is equipped with a tilting chute, and two copper water jacket chutes are arranged below the tilting chute. It is possible to choose to discharge to one chute and clean the other chute.
虹吸井顶盖（8）上方设置虹吸井工艺孔（7），当虹吸井内粘结、表面结壳或渣粘时，使用采用两相电极下熔池对搅拌处理。虹吸井表面结壳时，使用天然气喷枪消除表面结壳。A siphon well process hole (7) is set above the siphon well top cover (8). When the siphon well is stuck inside, crusted on the surface or slag is sticky, use the two-phase electrode to lower the molten pool for stirring treatment. When the surface of the siphon well is encrusted, use a natural gas spray gun to remove the surface encrustation.
利用上述镍顶吹炉虹吸排渣装置对镍顶吹炉渣进行排放，具体工艺过程如下：Utilize above-mentioned nickel top-blown furnace siphon slag removal device to discharge nickel top-blown furnace slag, the specific process is as follows:
（1）硫化镍精矿顶吹炉熔炼；硫化镍混合精矿、石英石熔剂、石灰石熔剂、精选原煤、烟灰等经圆盘和定量给料机配料后，通过胶带运输机运输至熔炼炉炉顶，通过移动胶带运输机加入炉内，熔炼炉镍熔炼炉渣Fe/SiO2为0.9～1.1，渣含Ni 1.2%～2.5%， 渣含MgO10%～14%，渣温1250℃～1300℃；(1) Nickel sulfide concentrate is smelted in a top-blown furnace; nickel sulfide mixed concentrate, quartz stone flux, limestone flux, selected raw coal, soot, etc. are batched by a disc and a quantitative feeder, and then transported to the melting furnace by a belt conveyor The top is fed into the furnace through the moving belt conveyor. The nickel smelting slag Fe/SiO 2 of the smelting furnace is 0.9~1.1, the slag contains Ni 1.2%~2.5%, the slag contains MgO10%~14%, and the slag temperature is 1250℃~1300℃;
（2）顶吹炉连续投料生产，熔体面上涨至2200mm，炉渣从虹吸井连续排出，根据炉内反应状况，顶吹炉液面保持稳定在2200~2400mm；(2) The top-blowing furnace is continuously fed into production, the melt level rises to 2200mm, and the slag is continuously discharged from the siphon well. According to the reaction status in the furnace, the liquid level of the top-blowing furnace remains stable at 2200~2400mm;
（3）顶吹炉停料时，虹吸井使用两相电极下熔池保温。(3) When the top-blowing furnace stops feeding, the siphon well uses the molten pool under the two-phase electrode to keep warm.
