  当热风炉停机或需要维修时,需进行保温,根据停机时间的长短和维修位置及设备的不同,可采取不同的保温方法。那么在做绝缘工作时我们需要注意什么呢?正确的绝缘知识是保证炉内温度稳定所必需的。
  When the hot blast stove is shut down or needs maintenance, it needs to be insulated. Different insulation methods can be adopted according to the length of shutdown time, maintenance location and equipment. So what should we pay attention to when we do insulation work? Correct insulation knowledge is necessary to ensure the temperature stability in the furnace.
  (1)高炉6天内风管、热风炉等多处维修工程,在风管受热前,炉顶温度将被烧至许用高值。
  (1) in 6 days of blast furnace, air ducts, hot blast furnaces and other maintenance works, before the air ducts are heated, the furnace top temperature will be burned to the allowable high value.
  (2)高炉10天无风,无维护工程。在高炉无风前需要对高炉进行冷却,特别是降低废气温度,在保温期间炉顶温度低于700℃时进行燃烧,可使废气温度维持10天。
  (2) the blast furnace is free of wind and maintenance works for 10 days. The blast furnace needs to be cooled before there is no blast, especially to reduce the temperature of exhaust gas. During the heat preservation period, the temperature of furnace top is lower than 700 ℃ and the temperature of exhaust gas can be maintained for 10 days.

  (3)若时间较长(超过10天),炉顶温度低于750C应加温;当排气温度高于350℃时,通过送风降温。为了防止热风进入高炉,在高炉和风管之间筑了一堵墙。
  (3) if the time is long (more than 10 days), the furnace top temperature shall be increased when it is lower than 750C; when the exhaust temperature is higher than 350 ℃, the temperature shall be reduced by air supply. In order to prevent the hot air from entering the blast furnace, a wall is built between the blast furnace and the air duct.
  当炉顶温度降至750℃时,强制燃烧,再燃烧时间为0.5 vl。哦,温度达到1100^ -12000c。当排气温度达到350℃时,通过送风降温。冷风量约100^-300m3/min,风压5kPa,冷空气由其他高炉分配或安装通风机。操作程序与热风炉正常工作程序一致。每班更换一台热风炉。
  When the top temperature of the furnace drops to 750 ℃, it is forced to burn, and the re burning time is 0.5 VL. Well, the maximum temperature is 1100 ^ - 12000c. When the exhaust temperature reaches 350 ℃, it is cooled by air supply. The cold air volume is about 100 ^ - 300m3 / min, the air pressure is 5kpa, and the cold air is distributed or installed by other blast furnaces. The operation procedure is consistent with the normal operation procedure of the hot blast stove. Replace one hot blast stove in each shift.
  通过以上介绍,我们可以看出,热风炉的保温是根据不同的工况进行操作的。这是一项需要你掌握一定技能的工作。在保温过程中,应及时观察设备的运行情况,并提前做好保温准备。
  Through the above introduction, we can see that the heat preservation of the hot blast furnace is operated according to different working conditions. This is a job that requires you to master certain skills. In the process of heat preservation, the operation of the equipment shall be observed in time and the heat preservation preparation shall be made in advance.
