steel shot
Steel
shot is a cutting tool for grinding, which consists of many small and hard
abrasive particles and bonding agent made of porous objects. Abrasive grain
directly responsible for the cutting work, because of the different thickness
of steel balls, the work piece after processing the surface roughness and
processing efficiency is not the same, abrasive coarse for coarse grinding,
grinding fine for fine grinding, abrasive thicker, The smaller the particle
size. Low hardness of the steel balls for grinding high hardness of the work piece,
steel shot in high-speed conditions, in order to ensure safety, should be
checked before installation, there should be no cracks and other defects; in order
to smooth the work of steel shot should be carried out before use Dynamic
balance test.

scarring. For two reasons: (1) and inferior steel pipe material uneven,
impurities. (2). And inferior material manufacturer guide equipment simple,
easy to stick steel, these impurities after the roll bite are prone to
scarring. 4. Easy generation and inferior material surface crack, the reason is
that it's blank is adobe, adobe air, adobe in the process of cooling due to the
effect of thermal stress, cracks, after rolling there is crack. 5. Easy to
scratch and inferior steel pipe, the reason is false and inferior steel pipe
factory equipment simple, easy to produce burr, scratch steel surfaces. Deep
scratches to reduce the strength of the steel. 6. No metallic luster and
inferior steel tube, reddish or similar to the color of the pig iron, for two
reasons: (1), the billet is adobe. (2), and inferior material rolling
temperature is not standard, their steel temperature is through visual inspection,
so can't austenitic area of the rolling by the regulation, the performance of
