The quality of enameled wire is largely dependent on the quality of raw materials, such as varnish and wire, as well as the objective conditions of the mechanical equipment. However, if a series of issues, including baking, annealing, speed, and others, are not adequately addressed, the quality of the enameled wire will suffer. If the operating techniques are not mastered, patrols and stop-and-sort are not carried out conscientiously, and process hygiene is not done well, even if the objective conditions are favourable, the production of high-quality enamelled wire will not be possible.
1. Prior to commencing operation, it is essential to activate the fan to facilitate the circulation of hot air within the furnace. It is essential to electrically preheat the furnace and catalytic zone in order to reach the specified catalytic combustion temperature.
2. There are three levels of diligence and three inspections in production operations.
It is important to measure the varnish film frequently, at least once every hour, and to calibrate the zero position of the micrometer before taking measurements. When measuring the wire, ensure that the micrometer is moving at the same speed as the wire and that the large wire is measured in two perpendicular directions.
It is important to regularly monitor the return line and adjust it as necessary. It is important to ensure that the lubricating oil is suitable for the task.
It is important to monitor the surface regularly to identify any defects, such as particles or paint peeling, that may occur during the coating process.
Once any issues are identified, it is essential to determine the root cause and implement a solution. In the event of defective products in the vehicle, please remove them promptly.
It is important to ensure that all moving parts are functioning correctly during operation. Particular attention should be paid to the tightness of the pay-off shaft in order to prevent issues such as rolling heads, broken wires and thinning wire diameters.
Monitor and adjust the temperature, speed and viscosity in line with the requirements of the process.
It is essential to ensure that the raw materials comply with the technical specifications throughout the production process.
3. It is also important to pay attention to the potential for explosions and combustion during the production and operation of enameled wire. Combustion can occur in the following ways:
The entire furnace chamber may burn, typically caused by high steam density in the furnace cross-section or high furnace temperature. Additionally, threading may result in excessive coating of several wires, leading to multiple wires catching fire. To prevent fire, it is essential to strictly control the process furnace temperature and ensure adequate ventilation.
4. Finishing after stopping.
Once the machine has been stopped, the main tasks are to clean the old glue from the furnace opening, clean the paint tank and guide pulley, paint the machine and clean the surrounding area. To maintain the cleanliness of the paint tank, cover it with paper if the machine is not going to be used immediately to prevent the introduction of impurities.
