Coke cupola
The coke cupola manufactured by SUNTHERM has the characteristics of high calorific value and stable combustion. Coke combustion can provide a stable heat source to ensure smooth raw material smelting. This is crucial for the continuous operation of the rock wool production line and stable product quality.
Coke produces less ash during combustion, which is conducive to reducing the formation of slag, thereby increasing the metal recovery rate. In rock wool production, the increase in metal recovery rate means the improvement of raw material utilization, thereby reducing production costs.
The coke cupola consists of a furnace body with a water-cooled jacket, a furnace bottom door and an opening device, a furnace bottom iron discharge port and an opening device, a blast port and an air ring, a siphon flow port, an upper furnace body, a distribution device, and a feeding port.
Curing furnace
The curing furnace produced by SUNTHERM uses far-infrared heating technology, which can directly heat the rock wool, reduce the loss of heat energy, and improve the heating efficiency. At the same time, it may also be combined with hot air circulation technology to ensure uniform temperature distribution in the furnace and further improve the heating effect.
The curing furnace is equipped with a high-precision temperature control sensor that can monitor the temperature in the furnace in real time and make precise adjustments according to the preset process parameters. The temperature control system adopts advanced algorithms and control strategies, which can automatically adjust the heating power and temperature curve according to the characteristics of rock wool and the requirements of the curing process to ensure the stability and consistency of the curing process.
The curing furnace is equipped with an automatic control system, which realizes fully automated operation from heating, curing to cooling, reduces manual intervention, and improves production efficiency and product quality.
The curing furnace also has remote monitoring and fault diagnosis functions, which can monitor the operating status and performance parameters of the equipment in real time, detect and handle abnormal situations in time, and ensure the stability and safety of the production process.
