Nitrited Low Carbon Ferro Chrome
The solid-phase decarburization reaction of high-carbon ferrochrome powder has the advantages of relatively low reaction temperature, good reaction selectivity, and relatively simple process flow. However, because the solid-phase reaction needs to undergo a nucleation and phase formation process, the solid-phase reaction will not occur. Requires longer reaction time and higher reaction energy.
Industrial Ferrochrome
Scholars from Taiyuan University of Technology conducted a kinetic study on the solid-phase decarburization of high-carbon ferrochrome powder using microwave heating. Calcium carbonate powder was used as the solid decarburization agent, and the carbon in the high-carbon ferrochrome powder and calcium carbonate powder were completely decomposed to produce The molar ratio of CO2 is 1:1 and 1:1.4. The high-carbon ferrochromium powder with calcium carbonate is heated to different temperatures in a microwave field and kept for a certain period of time to decarburize. Measure its carbon content and calculate solid-phase decarburization. apparent activation energy of the reaction.
High Carbon Ferro Chrome Low Silicon
Experiments show that when the proportion of calcium carbonate is increased, the decarburization rate of the material will increase accordingly, but the microwave heating rate of the mixed material will become smaller; for materials with the same decarburization molar ratio, as the decarburization temperature increases and the holding time increases, The decarburization rate of the material increases accordingly. When decarburization is held at 1200°C for 60 minutes, the decarburization effect of the material is best under the two decarburization molar ratios, with the decarburization rates being 65.56% and 82.96% respectively. The microwave field can promote the activation and diffusion of carbon and the adsorption and diffusion of CO2 in high-carbon ferrochrome powder.
