The First Manufacturer of Thermex In Tamilnadu
RKKR THERMEX
Why RKKR Thermex?
The last few decades has witnessed a demand for low-cost reinforcement bars of higher yield strength viz 450 N/mm2, as in UK or 500 N/mm2, as in Germany, Switzerland and France. Cold twisting and other means such as raising carbon content directly affected the elongation and ductility and hence were found unacceptable.
THERMEX®, from HSE GERMANY is one of two patented technologies to manufacture thermo processed bars worldwide, of which THERMEX® Bars have a 80% of the market share in India and a 60% market share worldwide.
A short, intensive but very precise in-line cooling of the rolled bar is imparted in THERMEX process through a proprietary system. This treatment results in a cooled hardened periphery. On further cooling of the bar, a thermal exchange ( THERMEX ) occurs between the core and cooled outside martensite surface where by the resultant bar structure is a distinct tempered martensite at the periphery and a fine grained ferrite - pearlite structure in the central zone.
The RKKR THERMEX bars produced as above have the unique qualities of desired high strength and toughness combined with excellent ductility.
We are able to produce Thermex 500 routinely with the desired bar structure obtained in the very first bar rolled out. No 'trial and error' is involved in Thermex Technology.
