Industrial furnace heat 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.The function of vacuum heat treatment for Cutting Tools 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.Debinding and sintering of metal injection molding components 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.Research on vacuum brazing technology of dissimilar metals Cold surface temperature is the most important variable that determines the economics of the entire furnace lining design. The selection of cold surface temperature should be determined based on comprehensive considerations such as reducing the heat loss of industrial furnaces and reducing production and infrastructure investment costs. Generally, the cold surface temperature of a continuously operating high-temperature industrial furnace is preferably 60 to 70°C. There are many variables involved in the heat transfer calculation of the furnace lining. In order to simplify the calculation, the concept of "thermal resistance" is introduced, thereby combining the two variables of the furnace lining thickness and material thermal conductivity into one variable.Effect of filler metal on vacuum brazing of cemented carbide and steel Posted at 12:43 AM |
