Техническое обслуживание и техническое ремонт спекающей кирпичной печи Китая Китай

В конце каждого года, на производство большинства предприятий по производству стеновых материалов влияют погода или праздник Весны., и они останутся на какое -то время производства. Это время может быть использовано для комплексной проверки, техническое обслуживание или техническое преобразование печей – туннельные печи, in order to make the production of the following year more convenient and efficient.
1. Обслуживание
After about three days of cooling down after the kiln is turned off, все тележки внутри печи можно вытащить. Тщательно осматривая печь внутри и снаружи, а также связанные с ней вспомогательные помещения и оборудование., and based on the understanding of the aging and damage situation in various places, можно составить план технического обслуживания.
1.1 Давление дымоудаления
Check whether there is any air leakage, трещины, collapse or other phenomena in the main flue and branch flue. Clean up any debris that affects ventilation, such as smoke and rust stains. Weld or replace severely corroded metal pipes. Clean up the broken blocks inside the Hafeng to solve the problem of hindering the pulling force and affecting the preheating of the lower part of the billet stack, and repair the wall of the Hafeng vent damaged by the collapse of the billet stack. Understand the usage status of the air brake, including durability and whether it is tightly closed, and whether it can be flexibly opened and closed. Кстати, check if the waste heat extraction system is working properly and perform maintenance on it one by one.
1.2 Kiln Wall and Kiln Roof
Check if there are cracks or protrusions on the kiln wall to determine if it is a precursor to the foundation sinking and endangering the kiln roof. Minor cracks with a small quantity can be ignored, and gaps larger than 2mm should be carefully examined. Especially if there are bricks falling and protruding from the kiln roof, they should be repaired. В противном случае, minor cracks can easily cause the brick stack to collapse, and severe ones can collapse during operation, leading to forced flameout and even injury accidents. Check for bubbles or lumps on the walls and roof of the high-temperature section kiln, which are often caused by poor material quality, improper masonry orientation, or insufficient length resulting in high-temperature burning. Check for any debris such as broken bricks in the contraction and expansion gaps, clean them, and then re plug them with aluminum silicate fiber cotton. Understand the quantity and extent of damage to the curved seal bricks, which are often caused by the following reasons: ① kiln car scratches and dents due to excessive height or width (some production problems or deformation caused by derailment, falling, and collision due to careless operation); ② Defects in local masonry or track laying of kiln walls; ③ Scratching of collapsed brick stacks. If the curved sealing bricks are damaged repeatedly, it will endanger the safety of the kiln walls and roof.
1.3 Sand sealing
After one year of use, a large amount of broken bricks, soil debris, fuel slag, and sand particles that have become finer due to friction will be mixed into the sand sealed groove, which will have a negative impact on normal sealing. Clean it completely before sieving it, removing impurities that are too large or too fine, leaving behinddry sand particlesthe size of mung beans for later use. Repair the collapsed or scraped sand groove, and then fill it with screened sand particles. Check if the Gaza pipeline is unobstructed, as it is prone to blockage due to sand particles being too wet or mixed with large debris.
