Causes of Surface Cracks in Wire Rod Rolling Mill

The cooling rate of high carbon steel wire rod after wire rod rolling mill rolling is too fast, which may also cause cracks in finished products, and the latter can also cause transverse cracks. Cracks formed by improper controlled cooling after rolling are not accompanied by decarbonization, and there is generally no oxide scale in the cracks.

Rolling (metalworking) Wikipedia

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
