Bhushan Steel relies Zwick for their material testing needs

Bhushan Steel Ltd is one of the prominent players in the Indian Steel industry. Backed with more than 27 years of experience, they are now India's 3rd largest Secondary Steel Producing Company with an existing steel production capacity of 5.6 million ton per annum. As one of the largest integrated steel players in India, BSL is a source for vivid variety of products such as Hot Rolled Coil, CRCA,CRFH,  Galvanized Coil and Sheet, Galume Coil and Sheet, Color Coated Coils, Color coated Tiles, High Tensile Steel Strips, Hardened & Tempered Steel Strips, Precision Tubes, HFW/ERW Pipe (API Grade),3LP Coated Pipes, Billets and sponge Iron. Being amongst the prime movers of the technological revolution in Indian Cold Rolled Steel Industry, BSL has emerged as the country's largest and the only Cold Rolled Steel Plant with an independent line for manufacturing Cold Rolled Coil and Sheet up to a width of 1700mm. Along with this we also have a Galvanized Coil and Sheet line up to a width of 1350 mm.

Bhushan Steel Ltd bought several machines for their Khopoli plant for testing their ERW Pipe of API grade and other grade Pipes. In order to carry out necessary material tests, they are using a 1200kN Universal testing Machine, 450J Automated Impact Tester with Notch Vision, device for measuring notch impact samples, Automated Vickers hardness tester and Rockwell Hardness Tester from Zwick Roell Group.

1200kN UTM: This 1200kN floor standing electro-mechanical screw driven UTM, model Z1200E, is used for performing tensile test on Raw Material and sections of finished pipes  at ambient temperature. As the UTM is screw driven and has a large travel, so every kind of samples can be tested by simply moving the crosshead. Fully front open and parallel acting hydraulic grips provides easy insertion of heavy samples which results in saving of energy and time. The UTM is equipped with fully automatic macro extensometer to automatically measure elongation upto break of the specimens starting from automatic gauge length setting, closing / opening of sensors arm and hence avoiding any human intervention to ensure reliable, repeatable and reproducible test results.                                                                                            

450J Impact Tester: The 450J Impact Testing Machine, model RKP450) is supplied with semi-automatic tempering and feeding unit with capacity of 21 samples in tampering unit for testing from -180°C to 300°C.  A high reproducibility of the test results is obtained because operator influences are excluded (hand temperature, moist hands, eccentric or inclined insertion of specimens etc.) and automatic alignment facility before the start of the test. The test is always done repeatedly within 5 seconds after taking the samples out of the tempering unit.

Vicker’s and Rockwell Hardness Tester: The Automated Vickers hardness tester, model ZHV30A,  helps the users to map the indentation required on the polished and etched welded samples at weld, seam and body and record these values of hardness with respect to distances between indentation. The hardness Tester is equipped with fully motorized T-slotted X-Y table, with Auto Focusing, Joy Stick and Powerful Software to run the machine automatically and store the data.The Rockwell hardness tester is suitable for testing all 8 Rockwell scales and has an unique nose mounted indenter which allows accessibility on difficult to reach test areas. The hardness testers were supplied with suitable UKAS accredited Indenters and test blocks compliant with the relevant ISO and ASTM standards. 

Shrikant Yadav, Asst Engineer and Markanday Kunwar, deputy manager – QC Lab of Bhushan Steel  said “ We using the Zwick products for a very long time and are satisfied with the reliable test results provided them. The service support provided by the Zwick India team is very efficient !
