Front box of cast rolling machine

Abstract

The invention discloses a front box of a cast rolling machine. The front box of the cast rolling machine comprises a box body, a first partition board, a second partition board and a third partition board, wherein the first partition board, the second partition board and the third partition board are arranged in the box body. The box body is divided by the first partition board into an upper box body layer and a lower box body layer. The second partition board and the third partition board are connected with the first partition board and are oppositely arranged in the upper box body layer in a spaced manner. The upper box body layer is divided by the second partition board and the third partition board into a liquid injection area, a filter area and an area to be cast and rolled. The liquid injection area and the filter area are spaced by the second partition board. The filter area and the area to be cast and rolled are spaced by the third partition board. The liquid injection area, the lower box body layer, the filter area and the area to be cast and rolled are communicated in sequence. According to the front box of the cast rolling machine, the stability of the liquid level in the front box of the cast rolling machine is improved, impurities in metal casting liquid are promoted to be deposited in the lower box body layer under the action of gravity, and the content of the impurities in the metal casting liquid is lowered.

Description

Technical field [0001] The invention relates to processing cast-rolling equipment, in particular to a front box of a cast-rolling mill. Background technique [0002] The front box is an indispensable equipment in the casting and rolling production line. The existing front box has a simple structure, and its shape is similar to a hexahedron without a top cover. There is no blocking device for casting liquid in the front box, and the flow control hole is near the movable runner. The outlet is on the bottom side near the casting nozzle. Taking the aluminum alloy casting and rolling production line as an example, the molten aluminum enters the front box from the flow control hole, and quickly enters the casting nozzle through the outlet, resulting in the following shortcomings in the existing front box: [0003] 1. The liquid aluminum stays in the front box for a short time, which causes a large amount of inclusions to be deposited in the nozzle, resulting in serious slagging inside t...

AI Technical Summary

Problems solved by technology

[0003] 1. The residence time of molten aluminum in the front box is short, so that a large amount of inclusions are deposited in the nozzle, resulting in serious slagging inside the cavity of the nozzle;

[0004] 2. The liquid level of the front box fluctuates greatly, which affects the quality of the product board surface;

[0005] 3. The aluminum liquid is unevenly distributed due to the presence of impurities;

[0006] 4. The temperature distribution of the melt in the nozzle is uneven
