The Manufacture of Steel
Iron occurs mainly as oxide ores, though it is also found in smaller quantities as its sulfide and carbonate. These other ores are usually first roasted to convert them into the oxide. On a world scale the most important ore is haematite (Fe2O3), but in New Zealand the starting materials are magnetite (Fe3O4) and titanomagnetite (Fe2TiO4). The oxides are reduced with carbon from coal, through t...
متن کاملA Soft Computing System for Modelling the Manufacture of Steel Components
In this paper we present a soft computing system developed to optimize the laser milling manufacture of high value steel components, a relatively new and interesting industrial technique. This multidisciplinary study is based on the application of neural projection models in conjunction with identification systems, in order to find the optimal operating conditions in this industrial issue. Sens...
متن کاملFungi and paper manufacture
Fungi have a significant impact on the economics of paper making and the end use of paper and products employing paper related components. Paper on a practical basis is a derivative of wood, and fungi that possess cellulose-degrading enzymes can directly impact the value and utility of various types of products. Fungi further have a negative economic impact on the pulp produced during paper man...
متن کاملStreamlining Cell Therapy Manufacture
T he cell therapy industry (CTI) is no longer a cottage industry; it is a distinct and sustainable component of the global healthcare sector (1). Today, CTI prospects are strong, with annual revenues exceeding US$1 billion/year, supported by improving investor sentiment and public support (1–3). The next phase of CTI growth — toward a multibillion-dollar global industry — will depend on the bio...
متن کاملThe Manufacture of Lactose
Industry throughout the world is faced with a common problem that of the disposal of waste materials from manufacturing processes. In the case of the dairy industry, one such 'waste' which is produced in enormous quantities is the whey resulting from cheese and casein manufacture. In the 1996/97 season alone it is estimated that around five billion litres of whey were produced in New Zealand. I...
