#$%^&*AU2020101680A420200917.pdf#####ABSTRACT The present invention discloses a device for measuring an instantaneous flow velocity and an instantaneous flow length of a high-temperature metal melt. The device includes a gate, a runner, a buffer tank, flow-shaped grooves, a horizontal working table and LRC-800 resistance measuring instruments. The buffer tank is connected to the runner and the flow-shaped grooves. The bottom of each of the flow-shaped grooves is provided with a groove body which has a length similar to that of the flow-shaped groove while having a width and a depth which are smaller than those of the flow-shaped groove. The groove body can be used for installing a resistance wire to test changes of a flow velocity of the high-temperature metal melt with time. Both ends of the resistance wire are connected to the LRC-800 resistance measuring instruments respectively. The device has a low manufacturing cost, is simple to operate, and can accurately measure the fluidity of the high-temperature metal melt, thus providing certain theoretical and experimental support for the casting industry.1/2 DRAWINGS 5 3 - - 2 14- -1 1 8 J -16 - 17 FIG.1I E-E FIG. 2 FIG. 3
