Schaeffler UK team successfully completed the the main trunnion bearing replacement BOS (Basic Oxygen Steelmaking) plant in Port Talbot, Tata Steel. Driven by replacement ear shaft bearing partition of rolling bearings, Schaeffler also help save customers five additional work. If has been used in a solid, rather than the split bearing, the customer will have to disassemble the large gear unit (i.e., the the BOS plant container main drive unit). Tata Steel Port Talbot the two BOS steelmaking vessels (V1 and V2) operation. The original container was installed in the late 1960s by the British company Ashmore, Benson, Pease and then upgrade grid in 1991/1992, including trunnion bearing replacement. Each container has a steel production capacity of 3.3 million tons. The BOS vessel operating losses will lead to a significant loss of revenue for the Tata Iron and Steel Company. Simon Life, the BOS plant department engineers Tata Steel Port Talbot comments, bearing replacement work is very successful. Schaeffler expertise throughout the installation process, the bearing of a high standard installation. Bearing conversion process , we encountered several components are damaged, and the top of the problem. however, all issues were discussed with Tata, Schaeffler engineers and central engineering support, between the parties, the solutions generated list of actions for the preparation and implementation of remedial measures. no expertise Schaeffler, the change in the bearing will not run so smoothly. "in July 2011, received a phone call from a region engineers BOS Schaeffler British plants, proposed a sudden bearing failure non-drive end (NDS) V2 BOS plant container. Shortly after the BOS plant engineers arranged a meeting, and a request was made two Schaeffler engineers on-site Port Talbot. Subsequent meetings took place in Port Talbot discuss the action plan and how to replace the trunnion bearings. Memories as a senior applications engineer Dave Wall, Schaeffler UK said: "the Schaeffler British, specified in the order and method statement documents drafting replace the bearings, and an overview of the TATA requirements in this document includes a detailed tool list and the drive side (DS) and the non-drive end bearing (NDS) removal and installation step by step process. "," standard "solid" relationship DS replaces a special FAG Spherical roller bearings SSRB, which is recommended replacement spare, because it reduces the downtime during the installation of the replacement bearings. NDS bearings are replaced with similar solid bearings. addition, a variety of peripheral components need to be replaced secondary damage caused by bearing failure have been identified, once confirmed, "Wall Street delete the drive side bearing, cutting existing bearing spent a total of 36 hours. The distance between the trunnion, the spacer (bearing seat width) measurements to determine required two special the Tata design, split "swallowtail" The thickness of the separator. These requirements, in order to ensure correctly secured in the proper position, and the new split bearing a new partition SRB inner ring half and the two halves of the clamping ring, the outer half-ring and the bottom roller cage, without any problem the fitting. Non-drive side of the removal of the original bearings bearing the NDS failed during operation, causing the BOS converter down. Now, some people put the lifting of the bearing housing and the housing cover, remove the partially damaged bearings, including cage pieces; fragments of the outer ring and the inner ring and the rolling elements. All components of the forensic examination, was rushed to the TATA Central Engineering Metallurgical and Inspection Department of the housing back cover, bearing the pressure plate and sets the interval was found to have been seriously damaged. New urgent production of Tata Iron and Steel Company, Central Branch (CES). The disintegration of the bearing inner ring and the sleeve to be cut off because of the shape of the deformation. After removing the damaged bearing, it was also found that the trunnion back bulkhead is in need of repair. Similarly, machining work urgently by the CES. Subsequent damage to the bearing housing, the Schaeffler expertise required to manually repair the surface and restore it back to an acceptable condition, in the process of demolition the NDS ladder extended bearing rollers have to be replaced. Bearing cover, solid grinding rollers for convenient trapezoidal replacement and installation of the TATA production houses must be kept away from the lower half of the use of specially manufactured beams magazine. The new bearings installed a new non-drive end bearing of the first pre-installed, in order to determine the the right sleeve partition width. The lower half of the casing, and then moving back to the original position, and beam construction deleted. Install new bearings is challenging, caused by the collapse of the original bearing vessels moving alignment. Reduce the converter is also a challenge, because ships must sideways finishing 40mm in order to achieve the correct installation position. Side turn a problem, initially to relieve the Contractor of the container, but succeeded in overcoming this problem. Final installation step DS and DS DS bearing, and the rest of the roller holder and the outer half-ring bearing mounting. Two bearings, installation and housing Caps 100% full of grease, including free space around. The position of the tensioning device and a new sealing member and the housing cover with a bolt fixed to the mounting of each bearing. Successful completion of the work, after two weeks, Schaeffler engineers glad to leave a very satisfied customer. Bearing installation, the job is not complete. Schaeffler British prepared a proposal to the actual maintenance schedule, engineer forwards the BOS, which is well received. In addition, customers have built "drawings of the cross-section is updated to show the actual parts of the V2 (measurement). Schaeffler UK to attend and bearing failure with the Tata Iron and Steel Company, replacement of bearings, BOS Review Conference of the blood vessels to make a contribution. "Since the replacement of the trunnion bearings Schaeffler UK engineers oversee further the BOS container bearing in a very short time, within a short period of two months, the converter C the SSI the UK  steel Taer Bo Special Harbour and converter. Schaeffler Group has been selected as the preferred supplier of two main trunnion bearing BOS factory vessels in Port Talbot, Tata Steel, "confirm Dave walls.
