Spheroidal Graphite Acicular Rolls

In addition to spheroidal graphite, spheroidal grafite acicular rolls include, bainite or acicular (bainite+martensite) which is formed as a result of high Ni-Mo alloying in structure. They have high wear resistance and also high thermal shock resistance. In order to remove the internal stresses and residual austenite after casting, low temperature and long-term tempering heat treatment is applied. It is generally preferred in rod, rib, wire rod finishing machines, light figured iron intermediate and finishing group and straightening and side rollers.
