Example Embodiment
[0020] Example 1: Press CaO 40%, SiO 2 30%, MgO 10%, 20% of other elements, select one or more of lime-based raw materials; select one or more of magnesium-based raw materials; select one or more of siliceous raw materials, and select flux minerals The standard deviation of one or more of the ingredients is controlled at 1%, and then the raw meal is prepared, and its fineness is over 100 meshes and enters the raw meal homogenization warehouse. When the homogenization degree reaches the standard and the deviation is not greater than 0.2%, the It is sintered in a mechanical shaft kiln. The sintering temperature is controlled at 1150 to 1250℃, and the sintering time is controlled at 8 hours. After the kiln is fully cooled, it is pulverized in the production workshop, and its fineness is over 100 mesh. When the temperature is less than 40℃ and the standard deviation is less than 0.2%, it can be packed in 50kg, 40kg, 25kg.
Example Embodiment
[0021] Embodiment two:
[0022] Press CaO 60%, SiO 2 20%, MgO 5%, 15% of other elements select one or more of calcareous raw materials, select one or more of magnesium raw materials; select one or more of siliceous raw materials, select flux mineral The standard deviation of one or more of the ingredients is controlled at 1%, and then the raw meal is prepared, and its fineness is over 100 meshes and enters the raw meal homogenization warehouse. When the homogenization degree reaches the standard and the deviation is not greater than 0.2%, the It is sintered in a rotary kiln. The sintering temperature is controlled at 1150 to 1250℃, and the sintering time is controlled at 0.5 hours. After the kiln is fully cooled, it is pulverized in the manufacturing workshop with a fineness of 100 meshes. After cooling, For homogenization, when the temperature is less than 40℃ and the standard deviation is less than 0.2%, it can be packed in 50kg, 40kg, 25kg.
