A large number of studies have shown that the addition of carbon raw materials will have a great impact on the fluidity and construction performance of calcium aluminate cement (CAC) combined with castables. In order to explore the impact of carbon raw materials on performance when used in Al2O3-SiC-C iron ditch castables, this paper uses site measurement, experimental equipment collection and result subdivision methods to collect data, streamline the algorithm and use the algorithm to better clarify the influencing factors. And design a theoretical result that can cover its influencing factors. Through microscopic inspection, the X-ray diffraction (XRD) images of the two sets of samples with 0.8% and 6.8% carbon content after heat treatment at 1050°C and 1500°C were studied. The results showed that the X-ray diffraction (XRD) images with 0.8% carbon content were compared with carbon. The main crystalline phases of the W group samples with a content of 6.8% are corundum and SiC. After heat treatment at 1500℃, the sample with 6.8% carbon content has a higher main peak of SiC than the sample with 0.8% carbon content. , Indicating that as the carbon content increases, more SiC is formed in the sample. Further exploring the high-temperature flexural strength of the sample after heat treatment at 1500℃, we can find that when the carbon addition is 4.7%, the high-temperature flexural strength of the sample has a maximum value of 2.8MPa. With the increase of the carbon addition, the sample the high temperature flexural strength has been improved. It has basically realized the combination of theory and practice, and obtained the available research results.
