请高手帮帮忙,谢谢!不要翻译软件直接照搬照抄的,翻译软件翻译的都不通顺
The reheating furnace is filled with hot-oxidizing combustion gases and the slabs are heated up by these gases. In addition, these gases react with the steel slabs resulting in the formation of iron oxide layer that is generally termed scale. As above mentioned, scale growth rate of most metals at high temperature follows the parabolic regime of Eq.(1).Fig. 5 shows growth of the scale layer on the top and bottom surface of the slab. As shown, since the temperature is relatively low from non-firing
Zone to preheating zone, the growth rate is low. On the other hand, the growth rate of the scale increases since the heating zone where the temperature is relatively high. Also, it can be seen from the figure that because of the temperature difference between the upper and lower zone of the furnace, the scale layer formed on the top slab surface is thicker than the scale layer formed on the bottom slab surface. At the furnace exit the thicknesses of scale on the top and bottom slab surfaces are 1.75mm and 1.55mm, respectively.
As listed in Table 1, the thermal conductivity of scale is very small compared to one of steel, while the specific heat of scale is somewhat large. As a result, the existence of scale formed on the slab surface can greatly affect the heat transfer behavior. Namely, due to the very small heat conductivity of scale, it should prevent the heat energy, which is transferred from the surroundings to the slab surface, from conducting into the inside of the slab. And the surface of scale should be slowly heated due to its large specific heat. Fig.6 shows the heat flux distribution on the surface and the temperature distribution inside the scale and slab in each zone of the furnace according to existence and non-existence of the scale. It can be seen that although more heat energy is transferred to the surface in a case of considering the scale layer, the surface temperature rises slowly due to the specific heat of the scale. Also, due to the thermal conductivity of the scale, the temperature gradient within the slab in that case is more severe, especially near surface.
