is transferred to the kiln stopping time, the inner fire material is uniformly heated, extended stay late time in the kiln charcoal, charcoal even cooling zone is supplied to the kiln, to accelerate the coal combustion remains favorable. This stage should be controlled to ensure that when the fire, temperature rise is too slow economy, particularly in the case of excess air coefficient is high, the kiln temperature is slow, but use less fuel missing. Because a lot of the excess heat is used to heat the air, and then discharged from the kiln in vain. But the fire was too much, too fast warming, will cause damage refractories, the more the need to prevent, and numerous production practice shows, the diameter of 2.5 meters below the kiln, the open kiln time (starting from the lead with firewood to start cutting only), lies in the three hours or so more appropriate, smaller kiln, the kiln time can also be shorter. Pulverized coal combustion stabilized, it should be fed through the primary air volume and the amount of coal regulation, so that the initial PCI used when a relatively high concentration of coal down. You must also analyze the pressure and flame kiln atmosphere, always adjust the kiln pumping force to ensure lower fuel burn more completely . Before feeding, kiln speed can be controlled slower than normal production. Furnace temperature was raised, then have to consider the question: When can I start feeding, how to feed materials, as well as what parts of the kiln temperature as the starting material under indicators, this indicator is selected properly, have a good feed the timing and amount of initial feeding on whether the feeder is easy to grasp, can not enter the firing zone in the material (also known as the expansion zone for ceramic kilns), the kiln is neither knot nor raw burn, are very important. Should be burning zone refractory surface temperature as an indicator for exhaust gas temperature indicator, as long as lower than normal production can be, because the Secretary kiln workers fear there is the following two situations: First, because of the kiln exhaust gas temperature high raw material particles into the kiln due to acute heat burst; Second burning zone temperature is too high, the material into a bonding occurs. Serious, outset knot ring, so that the height of the firing zone becomes uneven, leaving the kiln may easily hidden. Controlling the surface temperature of the refractory firing zone, to slightly below the sintering temperature of ceramic, it can prevent the junction kilns. At high temperatures, materials (regardless of its existing form is a solid, liquid or gaseous) the relationship between temperature and hue is a scientifically based, has long been engaged in high-temperature operation of the majority of staff (including silicates, metal smelting, metal heat treatment, etc. industry) use. In fact, the well-trained staff to see the fire, the mind goes on accumulated temperature and hue "table" than described in this article goes above table also subdivided specific, Rod Mill,pin crusher otherwise, how to deal with change in temperature kiln. As we all know, a lot of expansion temperature range of ceramic materials is less than 1000C. Two outside, before feeding, firing with refractory material layer covering the surface without the temperature is easy to see hue, it is easier to control the temperature.
