What are the stages of temperature control during the drying process of a newly built furnace?
0–150 degrees: Removal of free water from the lining; 150–350 degrees: Removal of crystalline water from the lining; 350 degrees and above: High-temperature sintering of the lining
⑴150°C, remove free water； ⑵320°C, removal of crystalline water ； ⑶500°C, sintering of refractory materials. With the new type of refractory lining, newly built heating furnaces no longer require drying out.
Although it is a new type of material that does not require baking, it is still best to undergo three stages of treatment
Pay attention to the preparation of the pouring material during construction; it is preferable that it be thick and water-resistant. After the pouring material is prepared, it is best to allow natural ventilation for more than 10 days. In this way, there is basically no need to heat the furnace.
