The Design of Automatic Control System for Tunnel Kiln Sintering Process
Tunnel kiln is one of the commonly used furnace types in the continuous firing process of refractory materials.The automatic control level of tunnel kiln has a crucial impact on the quality and cost of product firing.The tunnel kiln firing belt is equipped with multiple burners,and the temperature,firing atmosphere,and required pressure inside the kiln vary under different product firing curves.In the past,manual intervention during curve transformation was time-consuming and labor-intensive,and could easily cause temperature and pressure jumps,re-sulting in unqualified products.By optimizing the design of the automatic control system,the firing curve is associated with the cart system to achieve automatic control of kiln pressure,automatic adjustment of the optimal air fuel ratio for the entire kiln,automatic calculation of heating and insulation time and position,and automatic switching of firing curves for different product processes at different positions with the cart sys-tem.It has high automation and low firing cost,and has certain promotion and application value.
