In line with the Prime Minister’s “Make-in-India” initiative, H&K Rolling Mill Engineers Pvt. Ltd. has successfully commissioned its first indigenously manufactured 4-strand slit ‘Thermex Quenching and Self-Tempering’ pipe assembly at Mahalaxmi TMT Pvt. Ltd., Wardha, Maharashtra.

Franz Tamm, inventor of Thermex, the world’s leading Quenching & Self Tempering technology, congratulated H&K India on the successful transfer of slit-quenching technology from Hennigsdorfer Stahl Engineering GmbH, Germany (HSE Germany) to H&K India, leading to the seamless commissioning of the country’s first “Made-in-India” 4-strand slit quenching pipe assembly.

The H&K India team, led by its Chairman, Raj Kumar Markan, undertook the entire engineering and manufacturing process in India, including equipment design, raw material procurement, machining, assembly, testing, and erection and commissioning in less than 5 months. It only took rolling of a few billets for successful commissioning of the Thermex 4-strand slit quenching pipe assembly for rebar size 8mm at Mahalaxmi’s bar mill at Wardha.

“On testing, the 8-mm Thermex rebars recorded stellar properties such as Grades 550 and 600 with 1.14-1.17 stress ratio and 20-23 per cent elongation,” H&K informed.

H&K has revolutionised the Indian market by introducing the concept of quenching and self-tempering at a time when the standard Indian practice was to use Cold Twisted Deformed bars of grade Fe 415. The company introduced stop-start shears, Bundling-Binding Systems, grip tilters etc. in the Indian steel industry when it undertook the modernisation of the Durgapur Steel Plant and Kalyani Steel in 1990s.”

“The flawless execution of the 4-strand slit Thermex Quenching Pipe assembly is another testimony of our relentless efforts to upgrade Indian rolling mills with latest technologies from Europe,” Mr Markan said.

Mr Markan further opined that on reviewing the chemical composition and physical properties of the 8-mm rebars, it was observed that they met international standards and were as good as, if not better, than rebars of Indian primary producers. He has advised Mahalaxmi that it should maintain this level of quality rigorously. 

Yogesh Mandhani, Director, Mahalaxmi TMT Pvt. Ltd. announced that Mahalaxmi becomes the first bar mill in the country that has the capacity to effortlessly roll more than 1,000 tonnes of 8-mm Thermex rebars in a single day through the “Made-in-India” 4-strand slit Thermex pipe assembly.

The flawless execution of the 4-strand slit Thermex Quenching Pipe assembly is another testimony of our relentless efforts to upgrade Indian rolling mills with latest technologies from Europe.
