4安装方法合理安装是成功利用马氏体钢轧自壁的关键因素。为了部分地补偿马氏体钢轧自壁固有的低冲击韧性，必须使轧自壁得到很好的支撑，使导致结合面开裂的拉应力最小。下述归纳的安装方法，能保证位于轧自壁外侧用以及沿其结合面边缘的背村与上架体承接环有金属对金属的接触
4 installation method Reasonable installation is the successful use of martensitic steel rolling from the wall of the key factors. In order to partially compensate for the inherent low impact toughness of the martensitic steel rolling from the wall, the rolling must be well supported from the wall, minimizing the tensile stress that causes the joint to crack. The installation method summarized below can ensure the contact between the back village and the upper frame, which are located on the outer side of the wall and along the edge of the joint, to receive the metal-to-metal contact of the ring
