M S Billet

MS Billets are semi-finished products used to roll mills for construction of long products like wire rods. Steel Billets are extensively used in forge shops and machine shops for production of engineering goods and as feedstock for seamless tubes.MS Ingot, on the other hand, is commonly referred to the large-sized castings produced in a foundry. There are no specific dimensions for ingots. In steel plants, the molten metal from the blast furnace is poured into large, cylindrical ladles. Billets are generally smaller in size. When the cross-section of a casting is a square, it is referred to as a billet.

In MS Ingot casting, the liquid steel flows through a refractory channel & and fills up cast iron mold under the static condition from one side. This process has certain insufficiencies, viz. refractory particles chip-off from the channel and gets assorted with liquid steel to cause undesirable inclusions in Ingot that leads to rolling defect, whereas in MS Billet casting continuous casting technology liquid steel flows from a furnace to caster through a copper mold. The water in the mold gets cooled and oscillates at a determined rate. The cooling, oscillation, and pausing is done in a controlled condition for the liquid steel to solidify into equiaxed crystals. Due to the process of solidification of MS Ingot, segregation of chemical alloys takes place. The chemical properties differ at different portions of Ingot. However, in MS billets, because of the continuous casting, chemical alloys are uniformly spread.
