For kiln equipment such as rotary furnaces, we need to carefully understand its structural characteristics in order to better use and maintain it. Rotary furnaces are a commonly used firing equipment, with a wide range of uses, including particularly simple usage. However, even simple equipment has a structure, and in order to operate the equipment well, we need to have a thorough understanding of its structure. So, next, we need to have a thorough understanding of its structure Let's learn about the structure of the device
1. The rotary furnace body produced by our company consists of a furnace shell and a furnace lining. The furnace shell is welded from steel plates, while the furnace lining consists of three parts: a working layer, a permanent layer, and a filling layer. The working layer is directly in contact with the liquid metal, slag, and furnace gas in the furnace, and is prone to corrosion. Asphalt magnesium bricks are commonly used for masonry in China. The long-term layer is tightly attached to the furnace shell to protect the steel plate of the furnace shell. The long-term layer cannot be removed during furnace repair. Set a filling layer between the long-term layer and the working layer, consisting of tar magnesia or tar dolomite, to reduce the pressure on the furnace shell caused by the thermal expansion of the working layer and facilitate furnace dismantling 2. In order to reduce splashing and heat loss during blowing, as well as the discharge of furnace gas, the shape of the rotary furnace cap is made into a truncated cone or a spherical truncated cone, and its furnace mouth is a normal furnace mouth for feeding, inserting oxygen blowing pipes, and discharging furnace gas and slag. Therefore, the safety is poor 3. The buried tube water-cooled furnace mouth is a serpentine steel pipe used for cooling water that is buried in cast iron. This structure has lower cooling strength than the water tank type, but higher safety and lifespan than the water tank type 4. The water-cooled furnace mouth can be connected to the furnace cap with a wedge, but due to the bonding of the slag, it is often necessary to use flame cutting when replacing damaged furnace mouths. Therefore, in China, card welding is commonly used to fix the furnace mouth on the furnace cap in small and medium-sized converters 5. The rotary furnace body, which is the load-bearing part of the entire furnace, is cylindrical in shape 6. There are two types of furnace bottom: truncated cone type and spherical type There are three ways to connect the three sections of the furnace cap, furnace body, and furnace bottom: dead furnace cap, live furnace bottom, dead furnace cap, and overall furnace shell. The three types of connection are related to the furnace repair method, with both the dead furnace bottom and the overall furnace shell being repaired upwards, while the live furnace bottom is repaired downwards The above is the relevant introduction to the rotary furnace, which is very important for every part of its structural problems, has existing significance, and is indispensable. The reason why the rotary furnace equipment can operate normally is also due to the mutual coordination of its various parts. Therefore, we need to maintain each component well in our daily life
