| Abstract: | Using hot core box shooting machine, the core of sodium silicate-bonded sand was made, in which methyl formate gas was used as a curing agent. The effects of sodium silicate and methyl formate contents on core making process were analyzed. After the testing of process, the actual production parameters were determined and the trial production was carried out. The results show that the tested core-making process of sodium silicate-bonded sand can basically meet the production requirements. New sodium silicate-bonded sand is beneficial to environmental protection and has a certain cost advantage. |
