Abstract:
A basic research about microwave sintering of three kinds of concentrate has been investigated.Three parameters are included: microwave heating time,carbon addition in sample,variable basicity(CaO/SiO_2).As the microwave heating time increased,the temperature of magnetite concentrates increased too,once the temperature reached a point,the temperature change slowed down.With the same microwave heating condition,to add carbon powder will decrease the heating temperature of sample.In the condition of that the basicity is 2.5,the heating time is 20 min,and the microwave output power is 1 000 W,the sinter product with hole can be got,but the density is lower compared with the regular sinter product,and the reason needs a further research.
