Steel billets are rolled at temperatures exceeding 1700°F, above the recrystallization point, allowing them to be shaped into desired forms.
Bars are rapidly cooled using a specialized water spray system, hardening the surface while retaining a hot inner core.
Heat from the hot core is transferred to the hardened outer surface, ensuring balanced strength and flexibility.
Our TMT Bars undergo rigorous tests, including:
JBA billets are produced using the high-quality raw materials such as sponge iron and pig iron to produce ideal billets. To billets
are produced by screening the properties of the molten material.
The manufacturing of TMT bars involves in melting the raw material such as sponge iron and pig iron in the laboratory. The raw materials are clearly tested in the Steel Melting Shop before being sent for TMT steel manufacturing.
The raw materials are melted in an induction furnace and ladle heating furnace; the melted liquid is transferred to billet caster.
The continuous casting is performed in the molten steel where the liquid steel is transformed into the strands of metal; this semi-finished product is called billets; the steel billets.
