Refractory cement manufacturing of fire resistance is not less than 1580 degrees Celsius. According to different composition can be divided into aluminate refractory cement, low calcium aluminate refractory cement, calcium magnesium aluminate cement and dolomite refractory cement.
The main raw material of refractory cement is dolomite, which is made of high temperature cement by adding apatite and iron ore. The use of high temperature can produce chemical reaction and hardening materials, such as refractory sulfate, borate and phosphate as cementing materials such as high temperature resistant cement.
In order to ensure the construction of the series of refractory material have enough time to complete the mixing, transportation, molding and other processes, the cement initial setting time should not be too short; After construction, in order to cement as soon as possible to harden, produce strength, so the final setting time should not be too long. The initial setting time of refractory cement shall not be earlier than 45 minutes and the final setting time shall not be later than 390 minutes.
