Billet

Billet is a section of steel used for rolling into bars, rods and sections. Billets can be directly produced continuous casting. International standards :3SP/PS,5SP/PS, ASTM A 615 Grade 40, IS 2830, JIS 3101, SS400, ASTM-36, DIN 17100 ST 37.2, BS-4360, BS 4449.Q 235, Q237, Q257 . Billet casters solidify 80- to 175-millimetre squares or rounds, bloom casters solidify sections of 300 by 400 millimetres, and beam blank casters produce large, dog-bone-like sections that are directly fed into an I-beam or H-beam rolling mill. Huge slab casters solidify sections up to 250 millimetres thick and 2,600 millimetres wide at production rates of up to three million tons per year. In order to match the quantity of steel produced in a heat with the solidification capacity of a mold for a certain strand section, it is often necessary to use a multistrand caster. Some billet casters have six molds in one line next to one another, and all are fed from the same tundish.
