The demand for lower cost of spherical rubber joints makes its production process develop in the direction of short process and near final molding. The advantage of spherical rubber joint is that it can damage the casting arrangement of the ingot, refine the grain of stainless spherical rubber joint, and eliminate the defects of microscopic arrangement, then make the metallographic arrangement of spherical rubber joint more dense and improve the mechanical function. This improvement is generally reflected in the direction of rolling, and then the stainless steel plate is no longer isotropic to a certain extent, together with the effect of high temperature and pressure welding previously poured bubbles, cracks and loose.
