• Advantages: ingot can damage the organization, grain refinement, the elimination of tissue defects, so that the dense steel, mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the steel is no longer a certain degree of isotropic body, resulting in the pouring bubbles, cracks and loose, but also under high temperature and pressure welding.
