10 度即可。 Choose 10 degrees higher than the actual use temperature . According to the process requirements, calculate the actual required temperature difference to ensure the effect of baking. 160 度， 220 度， 360 度， 440 度，按最高设计温度 500 度做。 Example: If the use temperature is 160 degrees, 220 degrees, 360 degrees, 440 degrees, the maximum design temperature is 500 degrees. 个温度，如果是同一种产品。 4 temperatures, if it is the same product. Control is best to use SCR. Different products have slightly larger temperature differences when used at low temperatures. 度和 220 度的实际使用效果，没有低温烤箱好。 160 degrees and 220 degrees of actual use, not as good as a low temperature oven. 500 度烤箱， 160 度烘烤温差比低温 250 度烤箱要高 2~5 度。 Use a medium-temperature 500- degree oven. The 160- degree baking temperature difference is 2 to 5 degrees higher than a low-temperature 250- degree oven . It depends on the quality of the manufacturers' equipment. 0-250 度 ) 、中温 250-600 度 ) 、高温 (600-1500 度）超过 1200 度公司建议采用碳硅棒加热，完全可以根据产品的工艺要求选择。 The oven is divided into low temperature ( 0-250 degrees ) , medium temperature ( 250-600 degrees ) , high temperature (600-1500 degrees) more than 1200 degrees. The company recommends using carbon-silicon rods for heating, which can be selected according to the product's process requirements.Use and maintenance of industrial oven
1. Clean the surface and inner cavity of dust to keep the machine clean and hygienic.
2. Check whether the current of the ammeter is the same as normal. If there is something abnormal, notify the maintenance worker to carry out maintenance.
突然停电，要把加热开关关闭，防止来电时自动启动。 3. Sudden power failure, turn off the heating switch to prevent it from starting automatically when a call comes in.
4. Check whether the fan is running normally and there are no abnormal sounds. If there is any, turn off the machine immediately and notify the maintenance worker for maintenance.
检查通风口是否堵塞，并清理积尘。 5. Check if the vent is blocked and clean up the dust.
6. Whether the fan runs normally.
维修工检查电流是否正常。 7. The maintenance worker checks whether the current is normal.
8. Check whether the temperature controller is accurate. If not, please adjust the static compensation or sensor correction value of the temperature controller.
9. Check whether the heating tube is damaged and whether the line is aging.
10. Check whether the delayer is accurate and whether the error is allowed.
