Construction method for rotational flow pool bottom of bloom continuous casting machine
The invention relates to a construction method for a rotational flow pool bottom of a bloom continuous casting machine, and belongs to the technical field of construction of steelmaking bloom continuous casting machines. According to the technical scheme, the method comprises the following steps: 1, digging a circular pit in the center of the bottom of a rotational flow pool; 2, a steel pipe (15) is installed on a circular pit in the bottom of the rotational flow pool; thirdly, a metal frame is welded in the circumferential direction of the steel pipe (15), and pebbles and broken rocks with the thickness of 70-180 mm are added into the metal frame; fourthly, a layer of asphalt is poured on the steel plate (16) in a hot mode; fifthly, the blind plate (8) and an upper flange (10) of the steel pipe (15) are fastened and sealed through bolts (6), and then a plain concrete layer (3) is poured on the asphalt; sixthly, a reinforced concrete layer (2) is poured on the pool bottom plain concrete layer (3). The method has the beneficial effects that the efficiency of rotational flow pool bottom construction of the bloom continuous casting machine and the hit rate of rotational flow pool bottom construction water sealing can be improved, and the water sealing effect is good.
本发明涉及一种大方坯连铸机旋流池底的施工方法，属于炼钢大方坯连铸机建造技术领域。技术方案是：按照以下步骤进行操作：步骤一：在旋流池底部中心挖一个圆形坑；步骤二：将钢管（15）安装在旋流池底部的圆形坑上；步骤三：在钢管（15）的周向焊接金属框架，并在金属框架内填加70‑180mm厚的卵石和碎岩石；步骤四：在钢板（16）上热浇一层沥青；步骤五：用螺栓（6）把盲板（8）和钢管（15）的上法兰（10）紧固封死，然后在沥青上浇注素混凝土层（3）；步骤六：在池底素混凝土层（3）上浇注钢筋混凝土层（2）。本发明的有益效果是：能够提高大方坯连铸机旋流池底部施工的效率和旋流池底部施工封水的命中率，封水效果好。
