The resistance furnaces are insulated closed chambers with a provision for ventilation. Resistance-heated furnaces are compact and provide a secure environment for various processes. The most widely used resistance furnaces are indirect-heat ones that melt fusible metals. Temperature control is necessary for heated resistance furnaces as temperature could have to be kept constant or varied according to requirements. Temperature Control could be manual or automatic.
An Atmosphere Furnace is manufactured to accommodate broad processing areas where an inert atmosphere is required to protect heating samples prone to oxidation. The furnace offers clean finishes and is free of residues that would cause oxidation. The atmosphere furnace offers features for precise heating, consistent thermal homogeneity, and complete control over all thermal process parameters. An atmosphere furnace must have the tightness of its chamber to avoid the infiltration of external air. Let us read further to learn more about Resistance heated furnaces and Atmosphere Furnaces.
Applications of Resistance heated furnaces and Atmosphere Furnaces
The resistance furnaces are used for the following applications, including commercial and domestic cooking, drying and baking pottery, stove the enameled ware, heat treatment of metals such as hardening, annealing, etc. The resistance heated furnaces are necessary for sintering, melting, and heat treatment of the material and volatile experiments. The key features of an atmosphere furnace include ideal for inert atmosphere applications, double shell structure, uniform heat transfer, fan cooling method, excellent process control, etc. The Atmosphere Furnace is used in laboratories and industries that need to control each thermal work precisely. The controlled atmosphere furnaces are used for heat treatment performed in numerous atmospheres, including hydrogen, nitrogen, argon, ammonia, etc., and various other reducing and oxidizing atmospheres.
Types of Resistance Heated Furnaces
Resistance-heated furnaces include rocking-resistor furnaces, salt-bath Furnaces, resistance-heated batch furnaces, box-type resistance furnaces, etc. Salt-Bath Furnaces are used for tempering, quenching, and hardening steel tools. Using a Salt Bath Furnace, you can heat or cool work by immersing it in a liquid with the proper composition of fused salts. Salt Bath Furnaces facilitate various industrial applications in the aerospace, medical, and manufacturing industries.
Resistance-heated batch furnaces are commonly used in heat treatment. Where materials must be heated before they are melted, dried, or pressure shaped. Box-type resistance furnace, also known as muffle furnace, is basically for laboratory use. Its broad application areas cover industrial & mining enterprises, scientific research institutes, universities, laboratories, and other experiments purpose. In the rocking-resistor furnace. The whole body of the furnace is rocked clockwise and counter-clockwise to expose the charge to be heated to a desired atmosphere. It is used in manufacturing carbon film resistance in electronic circuits.
Advantages of Resistance heated furnaces and Atmosphere Furnaces
The resistance furnace benefits mining operations by offering a range of temperatures above 1500 C. An automated control unit in these furnaces is responsible for circulating and maintaining temperatures. Resistance-heated furnaces are well-sealed and have a vacuum that prevents heat from escaping. Resistance heated furnace contains a gaseous medium that eliminates chances of oxidizing and hardening metals. The advantages of the atmosphere furnace include Available in 1200°C, 1400°C and 1700°C temperatures, high performance; low energy consumption.
Thermal homogeneity; accurate controls and safety devices; reduction of operating costs; heating parts in any format; safety for the production process, etc. Furnace manufacturers can also customize atmosphere furnaces to meet specific application needs. According to the choice of temperature range, chamber size, and various valuable accessories available on request. The Atmosphere Furnace is used in laboratories and industries that need to control each thermal work precisely. The controlled atmosphere furnaces are used for heat treatment performed in numerous atmospheres, including hydrogen, nitrogen, argon, ammonia, and various other reducing and oxidizing atmospheres.
