Abstract:The upper material valve is a key device in the bell-less furnace top equipment. This article takes a new parallel-tank upper material valve as an example to introduce the composition, working process and principle of the upper material valve. The design of the upper material valve should be considered. The calculation of material quantity and hydraulic cylinder pressure, as well as the key technical points of this kind of upper material valve, the eccentric structure of the material punching cone liner and the drive shaft.

Key words:Bell-less furnace top;Upper material valve; Overfeed;Feeding structure;Drive shaft eccentric structure
