高炉炉皮的材质为A3钢,共由24带组成,总重344t,其纵、环焊缝共长达945m,其炉皮最大厚度为50mm,最小厚度为30mm。制作高炉炉皮时,首先要将炉皮边缘加工出X或K形坡口。开坡口时,通常是先在炉皮的一面放样、划样,铺设轴道后再切割坡口,然后再翻面。如此重复以上的工序。由于每块炉皮均较重,多次翻面不仅难度大,而且还大大降低了生产效率。为此,我们采用了单面铺轨 Blast furnace skin is made of A3 steel, a total of 24 with a total weight of 344t, the vertical and circumferential weld a total of 945m, the maximum thickness of the skin is 50mm, the minimum thickness of 30mm. Making blast furnace skin, the first edge of the furnace to be processed out of X or K-shaped groove. When opening a bevel, it is common to lay out a sample on the side of the furnace skin, pattern it, and then cut the bevel after laying the shaft, then turn it over again. Repeat the above procedure. Because each furnace skin are heavy, not only difficult to turn over several times, but also greatly reduce the production efficiency. To this end, we used a single track
