Heat therapy generally represents metalworking procedure used to alter actual physical and substance properties of components. In simple language the materials are heated or chilled at very high and low temperatures. It is a very sensitive procedure especially in the industrial manufacturer of metals This process requires special condition and to be precise controlled environments which are commonly termed as furnaces. This is where the actual heat treatment takes place. There are numerous types of furnaces and they are chosen according to their role. The furnaces are chosen according to unique factors such as the material type, temperature range, energy efficiency and the viscosity of the material. Every kind of heater is particular to its area of program. Heat therapy heaters have a number of applications.
A furnace is basically a thermal controlled environment and is employed to manufacture raw materials at high temperatures both in solid state and liquid state. Furnaces process specific materials in heat treatment and application areas. They can be categorized into physical or chemical types. In actual physical kind heaters the condition of the content remains the same In substance kind the condition changes from fluid to gas or the other way around. Physical type furnaces are coke oven for coal to coke conversion. Rotary kiln for cement production Hearth furnace for changing sulphide to oxide Continuous type for heat treatment. In chemical type furnaces ,induction furnaces for production of castings of metal alloys and flash melted for matte production.
For a furnace to be excellent it should possess several abilities. Energy performance, durability, excellent fluid circulation inside the heater, precise heat range management methods and excellent warm restoration program. Energy efficiency means that the furnace should use minimum energy to produce the desired results. The furnace design is vital to realize this ability. The furnace should be durable. This means that it should work its role for the longest time possible. Good fluid flow means that the fluid flowing in the furnace should not stop at any instance. The user interface in terms of temperature control should be exact. It should also have a good heat recovery system. Heat recovery system is where the heat transfer takes place.
Heat treatment furnaces require sources of energy. These sources of energy maybe fossil fuel ,electric energy or chemical energy. The most available energy source is the most advisable. Different types of heaters use different energy sources. Energy efficiency should be prioritized when choosing the furnace type. .It would be cost effective to minimize production costs.
Another requirement of furnaces is good refractory material, The refractory material should be excellent. Refractory design should be highly considered. Thermal enclosure of the heater is designed and made keeping the requirements in view For instance refractory facing the thermal enclosure must be chemically inert and refractory.
