About Co-Engineering Casting MachiningAssemblyMarkets Media Jobs Quality System At Proferro, our reputation is determined by the quality of our products and processes. Quality is built into our products and services, from the development, planning, all the way through to procurement, production, assembly, testing and training services. In 1994, Proferro obtained the ISO 9001 certificate, confirming our role as a trendsetter in quality assurance field in its sector. We appeal amongst other things to process controls and final inspection: spectrometric analysis, thermal analysis, ultrasonic testing, mechanical testing, micrography and 3D control systems. Furthermore, we are certified by various inspection bodies to provide test certificates for cast iron vessels. At Proferro, we also focus on ensuring World Class Manufacturing. Consequently, we are continually striving, with the help of all of our employees, to eliminate losses and become a world class company.

About Co-Engineering Casting MachiningAssemblyMarkets Media Jobs Melting Oven Cupola The iron is melted in the hot air blast cupola furnace and is then poured into the casting moulds. The hot air cupola has a melting capacity of 18 to 27 tons per hour and can melt basic iron for both nodular and grey cast iron. The charging system is fully automatic and the cupola consists of a long, vertical cylinder into which the charge is loaded from above. Hot air is blown in near to the bottom around the melting zone where the temperature is approximately 2000°C, enabling the iron and steel in the charge to melt. The coke causes carburetion of the metal and removes any rust by deoxidization. The entire process is controlled from the control room. The molten iron flows out at the bottom through a tap hole, while on the other side of the furnace the liquid slag is drawn off through the slag hole. The slag is used for road building and the construction industry. Before the molten iron is used for casting, thermal and spectrographic analyses are carried out in the lab to determine the carbon and silicon content as well as other elements.
