Aluminum shell -- how about the structure and principle of automatic stamping die?
The automatic stamping die adopts the drum type incineration system. The combustion supporting air is blown by a special fan. The pressure in the radiant tube is positive, which is higher than the pressure of the maintenance Gas in the furnace. In this way, in case of the rupture of the radiant tube, the oxidizing gas in the tube will enter the steel strip heating area. The automatic stamping die will lead to the oxidation of the steel strip and affect the product quality. Therefore, the drum type incineration system was later changed to suction type, and the pressure in the radiant tube was changed from positive pressure to negative pressure.
The pressure in the ejector tube is changed from positive pressure to negative pressure. The automatic stamping die incinerator adopts the method of directly controlling excess air. If the function of the ejector is not good, it will affect the incineration. Therefore, it is necessary to investigate the flame at any time and regularly measure the residual oxygen content in the waste gas.
