以往炼铜卧式转炉炉壳都是由简体部和端盖部组成,其端盖钢板由金属构件加固,并用拉杆和筒体部联接,为了避免耐火砖的膨胀和收缩引起的壳体变形,采用装在拉杆上的弹簧使端盖部和筒体部连紧,以保证炉壳的整体性和气密性。这种结构不仅部件 In the past, the horizontal converter shell of the copper smelting furnace consisted of a simplified part and an end cap part. The steel plate of the end cap was reinforced by a metal component and was connected with a rod and a barrel part. In order to avoid the deformation of the shell caused by the expansion and contraction of the firebrick, The spring mounted on the draw rod is used to tighten the end cap and the barrel to ensure the integrity and air tightness of the shell. This structure is not only a part
