What are the common quality issues in the construction of lime kilns
During the construction process of lime kilns, due to the involvement of multiple professional fields and complex processes, some quality problems are prone to occur, which have adverse effects on the subsequent operation of lime kilns.
Basic engineering issues
The foundation is the fundamental basis for the stable operation of lime kilns. If the foundation treatment is improper, such as the backfill soil not being compacted in place, or effective reinforcement measures not being taken for weak foundations, uneven settlement will occur under the load of the kiln body, leading to tilting and cracking of the kiln body, seriously affecting the structural safety and service life of the lime kiln.
Quality issues with masonry construction
The construction of refractory bricks is a crucial step in the construction of lime kilns. Uneven and incomplete thickness of the mortar joint is a common problem, which can lead to a decrease in the insulation performance of the kiln body, an increase in heat loss, and may also cause the bricks to loosen and fall off. In addition, the selection and arrangement of refractory bricks do not meet the design requirements. If the temperature distribution and material erosion inside the kiln are not considered, it will lead to premature damage of local refractory materials.
Construction issues of steel structures
If the welding quality of the steel structure is poor and there are weld defects, it will reduce the structural strength. At the same time, insufficient installation accuracy leads to loose connection of components, resulting in air and material leakage, which affects the thermal efficiency and production quality of the lime kiln.
The construction party needs to strengthen quality control, strictly control each link, and ensure that the construction quality of the lime kiln meets the standards.
