Hot rolled seamless steel pipe is generally manufactured on automatic pipe rolling mill.
Hot rolling can destroy the cast structure of steel ingot, thin the crystal particle of steel, and eliminate the disadvantage of microscopic structure, thereby improving the steel's mechanical propetry along the rolling direction.In this way, the steel is not is otropic body. Under high temperature and pressure , the bubbles, crackles and loosened placed can also be closed.
Meanwhile, under the high temperature of hot rolling, the rolled piece has small resistance to deformation and can be deformed to a large extent. For instance, the thickness of continuously cast bloom is generally about 230mm. After rough rolling and precision rolling, the final thickness is 1~20mm.
