Stainless steel heating oven tube after treatment is heating blue will not be red?
Unless they are not stainless steel, or they control the temperature of the heating tube, the continuous heating will be red, after all, the material has not changed. If the outside of the heating tube is ceramic, it won't be red.
Because sometimes we do tubular heater, in order to better improve its life, will reduce the heating pipe surface power, but it itself heating speed is slow, take more time to reach the temperature you want.
When the power is not enough, his argument is clearly untenable, and technology is a kind of metal surface treatment. Heating 250 degrees is not red, can not say is not normal, only can meet your work requirements, no problem.
