生产过程中发生停电，彩涂线热工设备的操作采取的措施

在生产过程中，如果发生突然停电，彩涂板关键的热工设备应根据各自的工作特点、相应采取不同的应对措施，具体如下:
　　(1)如果长时间停电，则可以打开彩涂板固化炉和焚烧炉的炉门，使炉温迅速降低，避免循环风机和排烟风机因长时间在高温状态下停车而损坏。

(2)彩涂板此时应避免各种明火接近炉区，以免发生爆炸危险。
　　(3) 彩涂板对各种循环风机，当介质温度低于250℃以下时，一般可不采取紧急措施;当介质温度高于250℃以下时，最好采取手工盘车的方式，使风机叶轮转动，以避免风机轴因长期高温状态下承受单向弯矩而弯曲，影响动平衡，直到介质温度低于250℃以下时，方可停止手工盘车操作。
　　(4)对排废气风机，因排废气温度一般在250℃左右，所以可不采取紧急措施。如果排废气温度超过250℃时，要采取手动盘车方式避免风机损坏。对补新风风机，由于工作温度为常温，所以也可不采取紧急措施。
　　(5)对烧炉排烟风机，应紧急切断烟道闸板，避免焚烧炉内的高温烟气进入排烟风机而损坏。如果此时烟气温度已经超过250℃时，要采取手动盘车方式避免风机损坏。
　　(6)对彩涂板固化炉各区燃烧机，由于燃烧机的连锁保护功能，煤气会自动切断，但为了保险还需要将各区彩涂板燃烧机的煤气入口阀门关闭，彻底切断煤气供应。
　　(7)对 彩涂板焚烧炉燃烧机，也应像固化炉燃烧机一样，关掉煤气入口门。另外，当焚烧炉的炉压为正时，应迅速打开焚烧炉炉门和燃烧机与焚烧炉之间的安装螺栓，拉动燃烧机内部将控制线路烧坏。操作时应特别注意避开从燃烧机安装口喷出的高温炉气，以避免烧伤。

In the production process, if there is a sudden power cut, the key thermal equipment of color coated sheet should take different measures according to their respective working characteristics, as follows:

(1) If the power is cut off for a long time, the doors of the color coated plate solidifying furnace and incinerator can be opened, so that the temperature of the furnace can be rapidly lowered and the damage of the circulating fan and the exhaust fan can be avoided due to the long time stopping at high temperature.
(2) All kinds of open fires should be avoided from approaching the furnace area in order to avoid explosion danger.
(3) For all kinds of circulating fans, when the medium temperature is lower than 250 C, emergency measures are generally not taken; when the medium temperature is higher than 250 C, it is better to take manual turning mode to make the fan impeller rotate, so as to avoid the fan shaft bending due to the long-term high temperature, affecting the dynamic balance until the medium. When the temperature is below 250 C, the manual turning operation can be stopped.
(4) For exhaust fan, because the temperature of exhaust gas is generally about 250 C, emergency measures can not be taken. If the temperature of exhaust gas exceeds 250 C, manual turning should be adopted to avoid fan damage. For the fresh air blower, because the working temperature is normal, no emergency measures can be taken.
(5) For the exhaust fan of the burner, the flue gate should be cut off urgently to avoid damage caused by high temperature flue gas entering the exhaust fan of the burner. If the flue gas temperature has exceeded 250 C at this time, it is necessary to adopt manual winding to avoid fan damage.
(6) Gas will be cut off automatically for burners in different areas of color coated plate solidification furnace due to the chain protection function of burners, but in order to insure, the gas inlet valves of color coated plate burners in different areas need to be closed and the gas supply completely cut off.
(7) For the burner of the color coated plate incinerator, the gas entrance door should also be shut down like the burner of the curing furnace. In addition, when the pressure of the incinerator is positive, the bolt between the door of the incinerator and the burner and the incinerator should be opened quickly to pull the internal control circuit of the burner to burn out. During operation, special attention should be paid to avoiding the high temperature furnace gas ejected from the burner mounting port in order to avoid burns.
