A Quantitative Bottom Injection Device for Melting Ingot Making

Abstract

The invention relates to a quantitative bottom injection device for melting ingots, which includes a ladle assembly, a plunger assembly and a ejection reset assembly, the ejection reset assembly is arranged on both sides of the ladle assembly, and the column The plug assembly is arranged above the ladle assembly through the ejection reset assembly, and the ejection reset assembly is drivingly connected with the plunger assembly; the ladle assembly includes a tundish, and the bottom of the tundish is set There are several flow passages; the plunger assembly includes several plungers corresponding to the flow passages; when the ejection reset assembly drives the plunger out, the gap between the plunger and the flow passage Open, the molten metal in the tundish is poured; when the ejector reset component drives the plunger to reset, the gap between the plunger and the flow channel is closed, and the molten metal in the tundish stops pouring. The invention improves the production safety, ingot quality and production efficiency of molten ingot making.

Description

technical field [0001] The invention relates to the field of high-temperature molten metal casting ingot making, in particular to a quantitative bottom injection device for molten ingot making. Background technique [0002] Metal ingot is an important auxiliary material for catalysis or deoxidation of molten steel in steelmaking plants. At present, most enterprises use the method of pouring high-temperature molten metal into a mold to make ingots. However, this method of ingot production faces many technical difficulties. The temperature of the molten metal in the tundish is too high to cause oxidation of the metal or the temperature is too low to cause poor fluidity of the molten metal; if the flow channel design is unreasonable, the flow channel mouth will have flashing edge; if the pouring method is unreasonable, it cannot Quantitative pouring leads to uneven weight of ingot products; if the pouring trajectory is too long and the pouring point is unreasonable, resulting i...
