WebThe cement production process, for example, starts with mining of limestone, which is then crushed and ground to powder. It is then preheated to save energy before being transferred to the kiln, the heart of the process. The kiln is then heated to a high temperature of up to 1480 degrees to convert the material to a molten form called clinker. WebTherefore dry out and initial heat-up methodology is very important. As cured most castable refractory mortars contain about 10% total water. Approximately 50 – 75% of this water is free water while the remainder is chemically bound. The free water has to be removed during air-drying and for a period of time at 230 degrees Fahrenheit. how many platforms at edinburgh waverley
