How to Control the Construction Quality of Industrial Lime Kiln Construction
As the core equipment for lime production, the construction quality of industrial lime shaft kiln directly affects production efficiency and product quality. To achieve high-quality construction, it is necessary to establish a rigorous quality control system from multiple aspects.
Material control is the foundation. Strictly review the qualification certificates of key materials such as steel and refractory materials, conduct sampling and re inspection to ensure that their strength, heat resistance and other indicators meet the standards. The fire resistance and load softening temperature of fire-resistant bricks must meet the design requirements, and inferior quality must be avoided.
The construction process is crucial. In the masonry process, follow the "Three One" bricklaying method to ensure that the mortar joints are uniform and full, with an error controlled within ± 2mm; The vertical deviation of the kiln body shall not exceed 0.15% of the height to ensure the stability of the kiln body structure. During welding operations, welders must hold a certificate and undergo non-destructive testing on the welds to avoid defects such as cracks and porosity.
Process supervision is indispensable. Arrange professional supervisors to be present throughout the entire process, conduct key inspections on concealed works such as foundation pouring and installation of kiln anchor components, and retain image data. After each process is completed, quality acceptance is carried out, and only after passing the inspection can the next step be entered.
By strictly controlling materials, standardizing construction processes, and strengthening process supervision, the construction quality of industrial lime shaft kilns can be effectively improved, laying a solid foundation for efficient production in the future.
