Although the quality of enameled wire depends to a large extent on the quality of raw materials such as paint and wires and the objective conditions of machinery and equipment, if the operation does not take a series of problems such as baking, annealing, speed, etc. seriously and understand their interrelationships , Without mastering the operating technology, not doing the touring work and parking arrangement work seriously, and not doing well in the process and hygiene, even if the objective conditions are good, it will not be able to produce high-quality enameled wire. Therefore, the decisive factor for a good enameled wire is people, and people's sense of responsibility for work.
1. Before starting the catalytic combustion hot air circulation enameling machine, the fan should be turned on to make the air in the furnace circulate at a slow speed. The furnace and the catalytic zone are preheated with electric heating, so that the temperature of the catalytic zone reaches the specified catalyst light-off temperature.
2. "Three Qin" and "Three Checks" in production operations.
The diligent paint film is measured once an hour, and the zero position of the micrometer card is corrected before the measurement. When measuring the line, the micrometer and the line are kept at the same speed, and the large line should be measured in two mutually perpendicular directions.
Frequent school wiring often observe the back and forth wiring and tension tightness, and correct it in time. Check whether the lubricating oil is proper.
Check the surface frequently and observe whether the enameled wire has any defects such as graininess and paint peeling during the coating process, find out the cause, and correct it immediately. For the defective products on the car, unscrew the axle in time.
Check the operation to check whether the running parts are normal. Pay attention to the tightness of the pay-off shaft to prevent the rolling head, wire breakage and wire diameter thinning.
Check the temperature, speed and viscosity according to the process requirements.
Continue to pay attention to whether the raw materials meet the technical requirements during the production process of raw materials.
3. In the enameled wire production operation, attention should also be paid to explosion and fire problems. There are several kinds of fire situations:
One is that the entire furnace is fully burned, which is often caused by the excessive density of all vapors in the cross section of the furnace or the excessively high furnace temperature;
The second reason is that when threading, the amount of paint on a few wires is too much, which causes a few wires to catch fire. To prevent fire, firstly, strictly control the temperature of the process furnace, and secondly, make the furnace ventilated smoothly.
4. Finishing after parking
The finishing work after parking mainly refers to cleaning the old glue at the furnace mouth, cleaning the paint tank and guide wheel, and doing the enameling machine and the surrounding environmental sanitation work. In order to keep the paint tank clean, if you do not drive immediately, cover the paint tank with paper to prevent the introduction of impurities.
