When the market is in an expansion phase, the necessity to increase the production is a must involving an expansion of the production facilities. The revamping of an existing plant set several constrains, mainly due to the ladle size, therefore the reduction of the tap to tap is the only solution: a faster furnace. When the market is stable or in recession, it is necessary to reduce the transformation costs through the efficiency of the whole process and of the production facilities, mainly the one of the melting furnace. The present paper has the aim to catalogue the main items affecting the “faster” and the “efficient” adjectives and to illustrate the last technological developments, such as the UHCP (Ultra High Chemical Power) furnace, that Concast has implemented allowing a further step ahead. Some outstanding UHCP will be analysed.
