Temperature and time in temperature of the product surface Composition of the atmosphere around the product When the combustion occurs around the stechiometric ratio normal conditions the oxidation due to the atmosphere composition is insignificant in comparison to that due to high temperature That means that in normal working conditions an increase of losses due to oxidation exclusively depends on a longer permanence of the products in a high temperature furnace which is normally due to stops or pace reductions not balanced by a ready and correct reduction of the zone temperatures T A C T 3 evaluates the permanence time of the product in the different areas of the furnace and can intervene immediately to correct the zone temperatures to maintain two main guidelines he products are discharged at correct temperature and are not overheated products reach the high temperature as late as possible thus reducing the time in temperature Decarburation control Also the depth of steel decarburation is directly proportional to the surface temperature and to time in temperature thats why the same principles that allow T A C T 3 to reduce oxidation also guarantee the decarburation reduction Capacity of heating curves repetition T A C T 3 is set up thanks to the collaboration of a process engineer and or with expert operators 2007 R A System All rights reserved Ver 1 2 15 06 2009 Page 8 of 43
