PROCESS QUALITY RANGE
The manufacturing facility for TMT Bars at Arun Vyapar Udyog was started in 2007 with the installation of the quenching system . In Jettherm Technology, steel billets are heated in a reheating furnace and rolled through a sequence of rolling stands, which progressively reduces the billet to the final size and shape of the reinforcing bar. The intensive quenching process involved here can be defined as cooling (usually using pure water or low-concentration water) at a rate several times faster than the rate of conventional quenching. Intensive quenching requires very high cooling rates for parts within the martensitic phase. Very fast and very uniform part cooling reduces the probability of part cracking and distortion, while improving the surface hardness and durability of steel Bar.
Quality Assurance at each stage of production from raw material purchase to finished goods handling ensures that the prescribed tests and inspections are strictly
adhered to. The TMT Bars are then delivered as per the agreed specifications/norms of quality.
Arun TMT Bars are made from MS Billets and InHouse Ingots and come in a wide range to suit a multitude of applications like:
- IS 1786 / 1985
- Grade: Fe 415 & 415D
- Size: 8 mm to 25 mm
- 12 mts length & customized length requirements.
