Embodiment Construction
[0024] A method for preparing low-viscosity mold flux for making steel mold castings, the parts by weight of the components are:
[0025] Modified fly ash 55
[0026] Blast furnace slag 20;
[0027] expanded perlite 30;
[0028] soda ash 5;
[0029] Expanded graphite powder 12
[0030] Flake graphite powder 5
[0031] Li 2 O 8;
[0032] Na 2 O 4;
[0033] The preparation of the modified fly ash is to place the burnt fly ash successively in 20% sulfuric acid and 16% sodium hydroxide solution, stir for 22 hours, and then filter out the fly ash from the acid-base immersion solution. , Rinse with deionized water until neutral, and test with PH test paper to confirm, finally filter, dry, and then send the three materials into the fluidization according to the weight ratio of fly ash: calcium carbonate powder: quartz sand powder 1:0.35:0.58 Roast at 1050-1100°C in the bed for 1.5 hours, and grind into nano powder after cooling;
[0034] It is obtained by mixing the raw mat...
