? ? Although the quality of enameled wire largely depends on the quality of raw materials such as paint and wire and the objective situation of mechanical equipment, if we do not seriously treat a series of problems such as baking, annealing and speed, do not master the operation technology, do not seriously patrol and stop sorting, and do not do a good job in process hygiene, we can not produce high-quality enamelled wire even if the objective conditions are good. Therefore, the decisive factor to do a good job of enamelled wire is people and people’s sense of responsibility for work.
1. Before starting the catalytic combustion hot air circulation enameling machine, turn on the fan to make the air in the furnace circulate slowly. Preheat the furnace and catalytic zone with electric heating to make the temperature of catalytic zone reach the specified catalyst combustion temperature.
2. Three attendance and three inspection in production operation.
The paint film shall be measured frequently and once every hour. The zero position shall be corrected with a dial card before measurement. When measuring the line, the dial card shall keep the same speed as the line, and the large line shall be measured in two vertical directions.
Frequently observe the back and forth arrangement and tension tightness, and correct it in time. Check whether the lubricating oil is suitable.
Often look at the surface, observe whether there are particles, paint peeling and other adverse phenomena during the coating process of enamelled wire, find out the causes and correct them immediately. For defective products in the vehicle, remove the axle in time.
Check whether all operating parts are normal during operation, and pay attention to the tightness of the pay off shaft to prevent rolling head, wire breakage and wire diameter thinning.
Check the temperature, speed and viscosity according to the process requirements.
During the production of raw materials, continue to pay attention to whether the raw materials meet the technical requirements.
3. During the production and operation of enamelled wire, attention shall also be paid to explosion and combustion. There are several situations of combustion:
Firstly, the complete combustion of the whole furnace is usually caused by too high steam density or too high furnace temperature in the cross section of the furnace; Secondly, when threading, the coating amount of several wires is too large, resulting in several wires on fire. Firstly, strictly control the process furnace temperature, and secondly make the furnace ventilated smoothly.
4. Clean up after stopping.
The finishing after topping is mainly to clean the old glue at the furnace mouth, clean the paint tank and guide wheel, and do the painting charter and surrounding environmental?sanitation. In order to keep the paint tank clean, if you don’t start immediately, please cover the paint tank with paper to avoid introducing dirt.
