Radyne wire line heads to India

INDUCTOTHERM Heating and Welding Limited has secured an order in India for its established Radyne spring wire line. Working with a global wire manufacturer and aiming for a production start date of late 2019, this specific IT (induction tempered) line will be designed to process 7mm to 14mm spring wire at a production rate of 2t/hr. The resulting hardened and tempered wire will be predominantly used for cold coiling of automotive suspension springs. The modern lines offer the efficient and clean technology of induction heating and safe and environmentally clean water quenching systems. The new temper lines produce material to a more consistent specification than the traditional oil tempered (OT) process. • Very little decarburisation due to the extremely short heating times • Minimal grain growth during heating • The ability to heat treat the more exotic alloy steels that require higher hardening temperatures • In some cases, producing material with higher tensile strength while maintaining ductility • High-efficiency environmentally frien- dly heat treatment process are manufactured to a high mechanical standard, using a precision-built modular design for ease of installation, maintenance and operation within the rigours of a wire production facility.

At the heart of the wire line is a PLC/ PC control system that utilises modern communication techniques to ensure ease of installation and reliable operation by minimising the number of interconnections that have to be made for the running of the line. The control system allows multiple wire setups to be stored in the PC memory, which are then downloaded to the PLC when required. The PC also operates a monitoring system that continually takes running data from the line and stores it for both immediate viewing and long-term historical review. The modern lines are designed to produce up to three tonnes of wire per hour and up to 17mm diameter wire. Materials that are processed include

carbon steels, chrome silicon and chrome silicon vanadium, such as SAE9254, EN10270/2 (2001), 55CrSi and wire to A229 specification. More recently the lines have been developed to cater for alloys containing nickel additions. One of the most important aspects of the Radyne line is its ability to run continuously, without slowing or stopping to change feed coil at payoff or to remove a coil at take up. The operator welds the end of the first coil to the beginning of the second coil while the line is still running. Inductotherm Heating andWelding – UK Website : www.inductothermhw.co.uk

Tenova HYL, a Tenova company leader in direct reduction, has been chosen by China’s Sinosteel Equipment and Engineering as the technology provider for a direct reduction (DR) micro-module for Empresa Siderúrgica del Mutún (ESM) at Puerto Suárez, municipality of Santa Cruz in Bolivia, South America. Tenova HYL’s direct reduction technology will be used for the first stage of the project, which will include a 250,000 metric t/year DRI facility, a 650,000 metric t/year concentration plant, a 400,000 metric t/year pelletising facility for Mina El Mutún and a steel plant with a continuous caster and rolling mill with a total capacity of 190,000 metric t/year of long products. This micro-module will use the Energiron Zero-Reformer (ZR) process and will be capable of supplying the melt shop with high-quality direct reduced iron (DRI) with metallisation levels of 94 per cent and an adjustable high carbon content in the range of three to four per cent. Micro-module ‘cornerstone’ for Bolivia

“We are very proud to be part of this groundbreaking project that after years of effort and planning has finally become a reality. It is very significant for us that ESM and Sinosteel chose our technology for the construction of this cornerstone in what surely is the beginning of the steelmaking industry in Bolivia,” said Rubén Rodríguez, sales manager at Tenova HYL. “After the recent successful projects in Asia, Africa, Europe and North America, we are glad that the first DR plant built in South America in the last 20 years will use the state-of-the-art Energiron technology,” added Stefano Maggiolino, president and CEO at Tenova HYL. “We trust that the team effort among ESM, Sinosteel and Tenova will be the key for the success of this strategic project that will promote a sustainable industrial development of Bolivia. The plant is expected to be in operation in mid-2021.”
