Chilled Rolls For Automatic Tmt Rolling Mills

We are engaged in manufacturing, exporting and supplying an excellent quality Chilled Rolls for Automatic TMT Rolling Mills to our valuable clients in Malerkotla, Punjab, India. Indefinite chilled cast iron rolls consist of a hardened layer of white cast graphite free cementite and the metallic matrix. The thickness of the usable chilled layer can be up to 20 mm depending on the roll diameter, The core material is grey solidified and consists mainly of a perlitic matrix with lamella graphite. Between the outer chilled shell and the core there is a mottled iron zone consisting of grey and white solidified microstructures, the surface hardness and the wear resistance of the chilled cast iron is determined by the amount of ledeburit in the microstructure and the structure of the matrix. A perlitic, bainitic or martensitic matrix can be obtained using special alloying elements. An increase in the hardness and wear resistance will cause a decrease in the thermal and mechanical capability.
