Thermex®, The Licensed Technology

HSE Germany developed, after years of research and field trials, a unique Quenching and Self-tempering (QST) process that allowed rolling mills to produce low-cost (without use of costly alloys), high strength deformed bars which fully met the demands of civil engineers of different countries. This basic process and subsequent improvements were patented worldwide.

Thermex® QST Technology gained immediate global acceptance due to its simplicity and ease-of-operation.

Thermex® Technology is available to rolling mills on a Licence basis.

Thermex clients obtain from H&K India all critical and proprietary equipment for the Thermex QST System. This critical and proprietary equipment is specifically designed to suit individual mill parameters and the rebar properties desired by the client. Thus, start-up time is reduced to a minimal and the desired Thermex rebar properties are established on Day 1.

Thermex®, The Process

A short, intensive but very precise in-line quenching of the rolled bar is imparted in Thermex® process through a proprietary system and this results in a hardened periphery.

On further cooling of the bar in atmosphere, a thermal exchange (THERMEX) occurs between the core and cooled outside martensite surface whereby the resultant bar structure is a distinct tempered martensite at periphery and a fine grained ferrite-pearlite structure in the central zone.

Thermex® Slit-Quenching, Made in India

H&K India has the expertise and experience to execute project orders for high-speed 2-strand, 3-strand and 4-strand Thermex® quenching systems.

The country’s first ‘Made in India’ 4-Strand Quenching Pipe was successfully commissioned by H&K India at Mahalaxmi TMT Pvt. Ltd, Wardha, Maharashtra.

This was due to the seamless transfer of slit quenching technology from HSE Germany.

H&K India, led by its Chairman, Raj Kumar Markan, undertook the entire engineering, manufacturing and commissioning process in less than 5 months. This included technology transfer, equipment design, raw material procurement, machining, assembly, testing, and erection and commissioning.

The Thermex® 4-strand quenching pipe at Mahalaxmi TMT Pvt. Ltd was successfully commissioned in less than 4 hours.

Currently, many high-speed slit orders are in operation and also under execution.
