SMS Demag modernized record CSP plant at JSW Steel - Economic regional online
JSW Steel Ltd., one of the largest steel producers in India, has awarded SMS Demag (www.sms-siemag.com) mandates the comprehensive modernization of the delivered SMS 1998 CSP plant at Dolvi, in the state of Maharashtra. The main objective is to increase the production capacity microsoft access from the current 3.0 million microsoft access to more than 3.3 million tons per year.
The CSP plant with the continuous caster No.. 1 started production in 1998 and was the CSP pioneer in India. In 2003 JSW production doubled with a second CSP caster. JSW Dolvi holds a casting speed of eight meters per minute microsoft access on average - and this for over a month - the world record in fast casting.
To achieve the goal of economic production microsoft access of 3.3 million tons per year, various modifications to the continuous caster and a comprehensive modernization of the electrical and automation systems to be implemented at the mill.
"The modernization concepts microsoft access of SMS Demag give us the opportunity to implement an extensive optimization of our system on the cutting edge of technology and automation without large standstill," says Ashok Kumar Aggarwal, Jt. Chief Executive Officer (CEO) of JSW Steel Ltd.
The capacity increase is achieved by a new strand guide and the extension of the cast strand no. 1 from the current 6,970 millimeters to 9,420 millimeters. For this, the casting platform no. 1 is raised to the level of the casting platform no. 2.
In the plant no. 1 the electromechanical oscillation is replaced by a hydraulic oscillation, with the same design and the same functions as in plant # 2., The new strand guide is equipped with Liquid Core Reduction (LCR1) and so also be able , the thickness microsoft access adjust flexibly. The mold level control microsoft access (Mold Level Control) is being modernized and provided with new hydraulics and appropriate microsoft access hardware.
SMS Demag has developed for the reconstruction of the mechanics and for the modernization of the electrical and automation systems, a custom approach that is transferable to other systems. The modernization of the electrical and automation microsoft access systems involves adjustments and additions in the control systems and the integration of technological systems such as X-Pact mold level control (Mold Level Control), hydraulic mold oscillation (Hydraulic Mold Oscillation) microsoft access and adjustment of the bending and straightening.
After the modernization of the plant is shedding microsoft access high quality slabs from niedriggekohlten (LC) and low HSLA steels, medium-carbon steels in the first place. For slab thicknesses from 65 to 50 millimeters, the plant is designed for a casting speed of up to seven meters per minute. The economics of spare parts inventory and maintenance increases significantly with the modernization, since the two continuous casting will be identical after conversion.
The existing electrical and automation is completely renewed by SMS Demag. The modernization, starting with the descaling of the six finishing stands and the cooling line to the two downcoilers including the federal government transport is realized microsoft access in a downtime of only 23 days.
"After the modernization, the caster will be equipped with the latest technology and automation. Our hot strip mill will be available with all-new automation and direct ac converted for production. We are sure that the application, which the team of SMS in terms of planning and level of detail and engineering shows, will provide for an even shorter standstill period as provided and may be that produced from the beginning in high quality, "says Satya Prakash, associate vice president (AVP) of JSW Steel Ltd.
Included with the X-Pact electrics and automation include the Level 2 control systems with pass schedule microsoft access calculation (PSC), profile, contour and flatness control (PCFC) microsoft access and cooling line control (CSC) and the replacement microsoft access of the complete Level-1 systems including the plant control microsoft access systems (TCS) and basic automation.
The implementation of the innovative HMI concept of SMS Demag with new control panels ensures an ergonomic control process. In order to allow the short shutdown of the plant, developed by SMS Demag Plug & Work method is used. The entire automation microsoft access with the original controllers at SMS Demag is tested against a real-time simulation of the CSP process and optimized. Errors are detected and removed in advance by this unique process. As part of the Plug & Work-testing and operating personnel of the customer is pre-trained microsoft access with the modernized system operation, so that the customer's personnel quickly einfi in the new operating concepts
