Embodiment Construction
[0026] refer to figure 1 , figure 2 As shown, the magnesium alloy continuous rheological casting and rolling feeding system device of the present invention mainly includes a front box and a feed nozzle connected subsequently; The inner cavity of the feed nozzle is connected.
[0027] The front box is built with a thermal insulation crucible 2. The function of the thermal insulation crucible is to store the magnesium alloy semi-solid slurry and provide stable slurry for the casting and rolling mill. The heat preservation crucible is divided into an upper heat preservation chamber 21 and a lower heat preservation chamber 22. The upper heat preservation chamber 21 is located higher than the lower heat preservation chamber 22. The bottom of the upper heat preservation chamber 21 is open and communicated with the lower heat preservation chamber 22 through a crucible guide tube 23. . And a feed pipe 5 is connected to the upper heat preservation chamber 21 through the feed inlet,...

The invention discloses a material feeding system device for continuous rheological casting and rolling of magnesium alloy, comprising a front box with a feeding port and a discharging port and a material feeding nozzle for following connection. The material feeding system device is characterized in that the front box is internally provided with a heat-insulating crucible which is divided into an upper-position heat-insulating chamber and a lower-position heat-insulating crucible; the upper-position heat-insulating chamber is higher than a lower-position heat-insulating chamber; the bottom of the upper-position heat-insulating chamber is provided with an opening and is communicated with the lower-position heat-insulating chamber by a crucible flow guide pipe; a feeding pipe is communicated into the upper-position heat-insulating chamber by the feeding port, a protecting gas pipe is communicated into a lower-position heat-insulating chamber by a protective gas inlet; the tail end of the lower-position heat-insulating chamber is provided with a discharging port which is communicated with an inner cavity of the material feeding nozzle by the flow guide pipe; three flow splitting blocks are fixed near the discharging port of the material feeding nozzle; and a magnesium alloy liquid level height stabilizer is arranged at the center of a heat-insulating cover at the top of the front box. The material feeding system device can be conveniently butted with magnesium alloy semisolid slurry equipment, and the prepared magnesium alloy semisolid slurry is stored and conveyed to a casting and rolling machine continuously and stably for casting, rolling and forming.
Description
technical field [0001] The invention belongs to the technical field of casting and rolling equipment for magnesium alloy strips, and in particular relates to a feeding system device for continuous rheological casting and rolling of magnesium alloys. Background technique [0002] At present, the consumption of magnesium alloys in the world is showing a growing trend. my country is a country with large magnesium resources, but the processing and production level of magnesium alloys is backward and the cost is too high, which seriously restricts the expansion of its application market. Therefore, the development of low-cost short-process technology suitable for magnesium alloys is an indispensable key technology to expand the application of magnesium alloys. [0003] The twin-roll continuous rheological casting-rolling technology combines the semi-solid processing technology with the twin-roll continuous casting-rolling technology, and combines the advantages of these two advan...
