KUNGFLEX PH152 R8 High Voltage Resistant Insulating Resin Insulating Tube is mainly used for insulation protection of conductive pipes on submerged arc furnaces to ensure the safe and stable operation of submerged arc furnaces. The following is a detailed analysis of the application of insulated tubes in submerged arc furnaces:
1. Overview of submerged arc furnace and its conductive tube
Submerged arc furnace, also known as electric arc furnace or resistance electric furnace, is mainly used for reducing raw materials such as smelting ores, carbonaceous reducing agents and solvents. It is an important equipment for the production of ferroalloys such as ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, and silicon-manganese alloys in the metallurgical industry.
The conductive pipe of the submerged arc furnace is one of its key components, which is subjected to harsh environments such as high temperature and high pressure during the working process. If the conductive pipe is poorly insulated, it is easy to lead to insulation failure, which in turn leads to safety accidents such as short circuit and fire.
2. Application of insulating tube in submerged heat furnace conductive tube
Insulation protection: The main function of the insulating pipe is to provide electrical insulation and prevent electrical connections between the conductive pipe and other components, so as to avoid the occurrence of safety accidents such as short circuit and fire.
High temperature resistance: The conductive pipe of the submerged arc furnace will produce high temperature when working, so the insulating pipe needs to have good high temperature resistance to ensure that it can still maintain a stable insulation effect in a high temperature environment.
Electrical properties: The insulated tube should also have excellent electrical properties such as high insulation resistance and low dielectric constant to ensure the electrical safety of the conductive tube.
Mechanical strength and corrosion resistance: The insulated pipe needs to have good mechanical strength and corrosion resistance to cope with the complex working conditions and environment of the submerged furnace, such as high temperature, high pressure, corrosive gas, etc.
3. Types and selection of insulating pipes
There are many types of insulating tubes in the market, such as glass fiber insulating sleeves, PVC sleeves, heat shrinkable sleeves, Teflon sleeves, ceramic sleeves, etc. These insulated tubes have their own advantages in terms of high temperature resistance, electrical properties, mechanical strength, etc. When selecting insulating pipes, it is necessary to consider comprehensively according to the specific working conditions and needs of the submerged arc furnace. For example, ceramic insulating materials have good high temperature resistance and electrical properties, and are suitable for insulation protection in high temperature environments; The glass fiber insulating sleeve has excellent flexibility and elasticity, as well as good dielectric and chemical resistance, and is suitable for wiring insulation and mechanical protection of motors, electrical appliances and other devices.
Fourth, the maintenance and inspection of insulating pipes
In order to ensure the long-term stable operation of the insulating tube on the submerged furnace, the conductive tube and its insulating material need to be inspected and maintained regularly. This includes checking that the insulating pipe is in good condition and that there is no damage or age, as well as checking that the connection between the conductive pipe and the insulating pipe is strong and reliable. If the insulated pipe is found to be damaged or aged, it should be replaced with a new insulating pipe in time to ensure electrical safety.
5. Example application
An insulating pipe clamping device for conductive copper pipe of submerged furnace gripper enhances the insulation effect and reduces the occurrence of leakage and arc phenomenon by using a pipe clamp made of epoxy resin insulating plate. The design of this insulated pipe clamping device is reasonable, the structure is simple, and the locking and loosening of the conductive copper pipe can be realized by adjusting the locking bolt, so as to ensure the electrical safety of the conductive copper pipe of the submerged furnace holder.
The application of insulating tubes in submerged arc furnaces is of great significance. By selecting high-quality insulating materials and strengthening daily inspection and maintenance work, the probability of safety accidents can be effectively reduced, and the production efficiency and service life of submerged arc furnaces can be improved.
