The process of heat transfer through the furnace lining in an industrial furnace is that the heat of the hot flue gas in the furnace is transferred to the furnace wall through radiation and convection. In the furnace lining, the heat is transferred from the inner wall to the outer wall through conduction.Vacuum brazing of ceramic and metal materials When calculating the heat transfer of the furnace lining, in order to simplify the calculation, the following assumptions are generally made based on the actual situation: 1. The thermal conductivity of the furnace lining is stable, that is, the heat flow (or heat intensity) does not change with time; 2. The thermal conductivity of the furnace lining is one-dimensional. , that is, heat is only transferred along the normal direction of the isothermal surface; 3. The thermal conductivity of each layer of material is constant and equal to the thermal conductivity at the average temperature of the wall temperatures on both sides of each layer of material; 4. The contact between each layer So good that the contact surfaces of the two layers have the same temperature.Atmospheric Pressure and Vacuum Sintering of High Purity Dense MgO Ceramics When designing furnace linings, heat-resistant and insulating materials are generally pre-selected based on the operating temperature of the industrial furnace (hot surface temperature), and then the cold surface temperature is selected to determine the thickness of various materials to meet the system design requirements.Applied Crack Repair Technology of Vacuum Brazing  Cold surface temperature is the most important variable that determines the economics of the entire furnace lining design.

According to the appearance, they are roughly divided into the following four categories: box furnaces, vertical furnaces, cylindrical furnaces, and large square furnaces. This classification method is based on the appearance of the radiation chamber and has nothing to do with the convection chamber. The so-called box furnace, as its name implies, has a radiation chamber that is a "box-shaped" hexahedron. vacuum-brazing-repair-method-for-cracks  Compared with it, the width of the radiation chamber of the vertical furnace is narrower, and the ratio between the distance between the two side walls and the height of the furnace is about 1:2.
