Although the quality of enameled aluminum wire largely depends on the quality of paint, wires, and other raw materials and the objective conditions of machinery and equipment, if the operation does not follow a series of issues such as baking, annealing, speed, etc., carefully understand the mutual relationship between them Relations, do not master the operation technology, do not do the inspection work and parking arrangements carefully, do not do the workmanship and sanitation, even if the objective conditions are good, the high-quality enameled wire cannot be produced. Therefore, the decisive factor for the quality of the enameled wire is people and their sense of responsibility for work.
1. Before starting the catalytic combustion hot air circulation enamel machine, the fan should be turned on to make the air in the furnace circulate slowly. The furnace and the catalytic zone are preheated by electric heating so that the temperature of the catalytic zone reaches the specified catalyst light-off temperature.
2. "Three checks" and "three checks" in production and operation.
The paint film is measured every hour, and the zero position of the micrometer card is corrected before the measurement. When measuring the line, the micrometer and the line maintain the same speed, and the large line should be measured in two directions perpendicular to each other.
Frequently check the wiring, always observe the back and forth wiring and tighten the tightness, and correct it in time. Check whether the lubricating oil is suitable.
Check the surface frequently to 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 defective products on the car, unscrew the axle in time.
Check the operation, check whether the moving parts are normal. Pay attention to the tightness of the pay-off shaft to prevent winding head, wire breakage, and wire diameter reduction.
Check temperature, speed, and viscosity according to process requirements.
In the production process of raw materials, continue to pay attention to whether the raw materials meet the technical requirements.
3. In the enameled wire production operation, attention should also be paid to explosion and fire problems. There are several fire situations:
One is that the entire furnace is fully burned, which is often caused by the excessive density of all steam in the furnace section or the excessively high furnace temperature;
The second reason is that the amount of paint on the wires was too much when the wires were threaded, which caused the wires to catch fire. To prevent fires, one is to strictly control the temperature of the process furnace, and the other is to ensure smooth ventilation in the furnace.
4. Tidy up after parking
The finishing work after parking is mainly to clean the old glue at the furnace mouth, clean the paint trough and guide wheel, and do a good job in the glazing machine and the surrounding environmental sanitation. In order to keep the paint cans clean, if you do not drive immediately, cover the paint cans with paper to prevent impurities from entering.
