Guangdong Shaoguan modernising with addition of advanced Kocks machinery

THE Chinese iron and steel producer Guangdong Shaoguan Iron and Steel Group Company has commissioned a new combined wire rod and BIC line incorporating a RSB ® 300++/4 in 5.0 design from Friedrich Kocks GmbH & Co KG, Germany. The RSB ® 300++/4 operates as a finishing unit for the production of BIC within a dimensional range from Ø15.0 up to Ø50mm and supplies as pre-finisher all feeders for the wire rod line. Thanks to the remote control system, size changes can apply within a billet gap and stand changes can be done within a maximum of five minutes due to the advanced stand quick change design.

EVT Eiberger Verfahrenstechnik releases innovative tube cleaning model – the VARIO

EVT EIDERGER Verfahrenstechnik GmbH has been supplying the metalworking industry worldwide with parts cleaning plants for the use of solvents of all kinds for 26 years. In addition to CHCs such as perchlorethylene (PER) and methylene chloride (MeCl), hydrocarbons (KWL) and modified alcohols are used. The size of the system and the process technology are based on the geometry and the desired throughput of the workpieces to be cleaned. From the smallest turned or stamped parts to large engine parts for aircraft and rocket engines through to drive shafts weighing tons for marine diesel engines – the variety of parts that is cleaned in EVT plants is enormous.

Even 10m long copper pipes with an average batch weight of 2.5 tons have been cleaned in EVT systems on the American market for many years. “In our recently developed cleaning system, pipe coils are cleaned and dried inside and out,” said Harald Eiberger, managing director of EVT GmbH. This procedure in this form has so far only been successfully implemented by EVT. The tubes wound on coils have an inside diameter of less than 1mm and an unwound length of 3km. Connected to a hydraulic system, the tubes are rinsed with solvent under 300 bar and then dried with nitrogen. With the experience from over 500 built plants, EVT engineers have now developed a new basic model.

cleaning processes customary on the market and also contain new cleaning- effective process steps that you won’t find in conventional cleaning systems.” Michel Lubinsky, sales manager at EVT, is certain that this range of programs can meet almost all cleaning requirements. In addition to spray cleaning with high pressure at approximately 10 to 12 bar, turbulent cleaning in combination with flooding the working chamber, the new process steps also include the boiling of the solvent in the working chamber during the immersion cleaning process. The movement of goods can be designed individually for each process step. EVT is in a steady process of gaining know-how, which is characterised by the type of plants that are built there. All are special systems, there is nothing from the rod – yet a good middle way has been found to summarise modules, where individual assemblies remain the same. In this way, the design and production process can be optimised, while maintaining the individualisation possibilities. The next 500 plants will also bring some innovations and EVT will continue to deliver reliable results as a creative and solution-oriented partner and advisor on industrial parts cleaning.

“The task was to plan a plant that can work with all common solvents and be equipped with both Schäfer baskets and EURO baskets as standard,” explained engi- neer Stefan Haag, who played a key role in the construction of the new type of plants. “The new system should be able to reproduce all
