Raymond's grinding roller grinding ring fails to escape the gas during metal solidification process. The metal is formed in a small hole, the ultrasonic wave has a high reflectivity, and because of its substantially spherical or elliptical shape, the porosity of the steel ingot is forged. Or after rolling, it is flattened into area type defects and found to benefit from ultrasonic testing. Ultrafine grinding of the grinding ring during the reaction of the grinding ring, or the addition of some components of the metal parts of the material to form incompletely molten metal inclusions, such as high density, high melting point, such as tungsten, molybdenum.
