The heating rate of the combustion furnace is determined according to the data provided by the manufacturer. Pay main attention to the removal of adsorbed water and crystalline water; actively participate
All of these have temperature rise curves; if you need them, I can send them to you! Up to 600 degrees, the temperature increase is 10 degrees; above that, it is 25 degrees per unit
The heating rate is related to the refractory materials: during the first start-up, it is necessary to dry the refractory materials, and a constant temperature must be maintained. The technical manual specifies that the temperature should be maintained at 120 degrees, 350 degrees, and 500 degrees. The heating rate is generally required not to exceed 10 degrees. For normal driving, according to the manual, a heating rate of around 10 degrees is required. However, given the inherent properties of refractory materials, heating at a rate of 30 degrees will not cause any problems. As a reminder, no problems will occur during heating, but be sure to pay attention to the cooling rate when stopping the machine. If a brick + castable structure is used, the cooling rate must be carefully controlled, as this can lead to the bricks coming loose.
How is the cooling rate controlled? What is the general control level?
The new furnace should be heated in accordance with the heating curve provided by the manufacturer; thereafter, the heating rate can be increased slightly
Driving for the first time 7×24 hours. Drive normally for 1×24 or 2×24 hours. The heating rate is 10 degrees per hour below 300 degrees, and 15 to 20 degrees per hour above that. The oven drying curve provided by the manufacturer should be referred to. Some take a relatively short time, while others take a relatively long time.
