Brick kiln out effective prevention method

Article source：

Rotary kiln can be applied to various areas, such as building materials, metallurgy, environmental protection and other aspects. The operation of the rotary kiln inevitable emergence of some failures, as long as we can well prevent these problems can make the losses to a minimum. Fall within the brick kiln phenomenon believe that many users have encountered, red brick kiln off situations occur, you must immediately stop the kiln, kiln, etc. After cooling again in accordance with the criteria to select and fine refractory lining of the kiln for inserts puzzle, the kiln lining made of masonry is completed, the ignition temperature according to the standard curve, and the temperature was increased slowly in the axial direction between the refractory combustion slowly paperboard, cardboard will be a gap between the expansion of the refractory block up, the temperature gradually rises, the radial direction between the brick and the brick joints iron will react to form a new crystalline phase, which has high temperature characteristics, even as a whole will bricks, the heating temperature in the rotary kiln process, must be avoided which could lead to heat generation of the interrupt factor, and the collapse of the refractory bricks and the appearance of damage are not allowed. Once its solution is not easy, so that everything should take preventive measures to advance the prevention of this phenomenon, for the prevention of brick kiln out an effective way for you to be summarized as follows: 1, first firebrick selection, to have high refractoriness, Fight transition temperature resistance, corrosion resistance, compact machining defects and other characteristics. 2, in the rotary kiln to heat the liner to be strictly in accordance with the heating temperature curve, so that the temperature rise slowly after the ignition, the production conditions in certain circumstances, can be used or a kiln exit gas temperature of the cyclone as control indicators, the general heating up time of 24-48 hours. 3, according to the actual diameter of the rotary kiln and the supply of bricks brick masonry to select the appropriate method. 4, in the brick kiln handling process, we should be very careful not to be hit, but not brutal handling, the bricks are incomplete or fine cracks appear. 5, on entering the venue of the bricks to be sub-categories storage, different specifications should be stored separately to avoid mixed together, resulting in identification difficult. 6, brick store to avoid the rain, and in the use of defective and get wet are not able to use. 7, in the rotary kiln refractory brick type and size should be uniform, you can mark them in order to avoid the generation of an error, resulting in an accident arising out of bricks. 8, in bricklaying bricks workers, must be through professional training and assessment through, and with a strong sense of responsibility, to ensure the kiln lining inlay puzzle without any quality problems.
