At present, domestic and foreign titanium alloy block manufacturers generally choose round cake-shaped briquettes. The round cake-shaped briquettes have the advantages of balanced force, uniform compaction density, simple pressing equipment requirements, and long tool life. But it also has its shortcomings, which are mainly manifested in the low charging efficiency, low space utilization, and prolonged pre-vacuum time when the volume of the material box is fixed. The melting rate of the round cake-shaped briquette material is not as stable as the rectangular briquette material, and the probability of the material phenomenon is big.

In accordance with the purpose of the utility model, in order to improve the efficiency of charging, increase the utilization rate of the space of the material box, significantly shorten the pre-vacuum time, significantly increase the titanium melting rate, reduce the phenomenon of miscellaneous materials, improve the quality of smelting, and reduce energy consumption. After changing the round cake-shaped briquettes to rectangular briquettes, the charging efficiency is improved, the space utilization rate of the bin is increased, the pre-vacuum time is significantly shortened, the titanium melting rate is significantly improved, the phenomenon of smelting is reduced, and the quality of titanium smelting is improved. Reduce energy consumption.
