Heat Treatment Steel plates 40 cm per side and 1 cm thick are heat treated in a static oven. Inside the oven there is a shelf where 10 separate plates are placed, in such a way that the heat treatment of one does not affect the treatment of the others. The oven is electric and emits radiation heat towards the plates. In the oven an atmosphere with nitrogen is generated to avoid the oxidation of the material, this gas acts as a convective medium on the plates. Before being placed in the oven, the plates are at room temperature of 25 ° C. The heat treatment of the plates begins with a preheating. At this stage, the combined convection and radiation heat transfer coefficient in the oven is 46 W / m2- ° C. During preheating, the oven controls the internal temperature with a quadratic compensation, therefore, the walls and the nitrogen atmosphere have a temperature Th that varies according to the expression: Th = a + bt2 where a = 750 °C, b = 3 x 10- 5°C/ s2 and t is the time in seconds.…

Don’t use Heissler charts to answer this question Heat sterilization of lumber, timbers, and pallets is used to kill insects to prevent their transfer between countries in international trade. This is analogous to food sterilization by heat. A typical requirement here is that the slowest heating point of any woodconfiguration be held at 56 °C for 30 minutes. Consider hot air heating of wooden boards that maintains their surface temperature at 70 °C.
