Double-faced cooling multifunctional efficient vacuum rapid-condensing furnace

Abstract

The invention belongs to the technical field of vacuum rapid-condensing furnaces and particularly relates to a double-faced cooling multifunctional efficient vacuum rapid-condensing furnace. According to the double-faced cooling multifunctional efficient vacuum rapid-condensing furnace, in a smelting chamber, a pure metal raw material is melted in an inductor and casted, after passing a funnel and a tundish, molten metal is rapidly condensed to be a slice on the surface of a water-cooling roller, and then the slice falls into a water-cooling material receiving barrel through a slice crushing mechanism, an upper guiding device and a lower guiding device to be subjected to secondary cooling; a gas cooling device is additionally arranged above the water-cooling roller, made of red copper and of a fan-shaped hollow interlayer structure, a cooling water pipe for cooling is arranged on the side, close to the water-cooling roller, of a copper plate, a plurality of exhaust holes are drilled in the copper plate, and cooling gas is introduced into a hollow interlayer; and the funnel and the tundish which are used for casting the molten metal, a tundish moving mechanism and a water-cooling roller mechanism are placed on the same moving trolley, the slice crushing mechanism is arranged below the water-cooling roller and comprises two shafts which rotate relatively, each shaft is provided with multiple rows of external gears, and the gears of the two shafts are arranged in a staggered mode, so that the magnetic performance is improved.

Description

technical field [0001] The invention belongs to the technical field of vacuum quick-setting furnaces, in particular to a double-sided cooling multifunctional high-efficiency vacuum quick-setting furnace. Background technique [0002] The existing vacuum quick-setting furnace is a water-cooled roller single-sided cooling sheet quick-setting furnace (SC furnace). In the melting chamber, the pure metal raw material is melted in the inductor, and after passing through the tundish, the surface of the water-cooled roller is quick-condensed into a thin sheet, and then Drop into the water-cooled plate for secondary cooling, and stir on the water-cooled plate with a stirring mechanism with cold air to reach the temperature of the furnace, and then manually release the flakes from the furnace. The metal flakes are cooled on one side on the surface of the water-cooled roller, and the flakes are crystallized on the side of the roll. Good, but the crystallization effect on the free side ...

[0002] The existing vacuum quick-setting furnace is a water-cooled roller single-sided cooling sheet quick-setting furnace (SC furnace). In the melting chamber, the pure metal raw material is melted in the inductor, and after passing through the tundish, the surface of the water-cooled roller is quick-condensed into a thin sheet, and then Drop into the water-cooled plate for secondary cooling, and stir on the water-cooled plate with a stirring mechanism with cold air to reach the temperature of the furnace, and then manually release the flakes from the furnace. The metal flakes are cooled on one side on the surface of the water-cooled roller, and the flakes are crystallized on the side of the roll. Good, but the crystallization effect on the free side is not ideal. When the air is cooled, some fine metals will be blown away, resulting in a decrease in the yield of the material. During the casting and quick-setting process, some harmful substances will be adsorbed on the upper surface of the sheet, which will affect the product quality. The cooling time of the flakes in the water cooling plate is long and the production efficiency is not high due to the manual operation of the furnace. The working environment is harsh and the cycle is long when the water cooling roller is polished and the tundish is replaced. The outer dimension of the metal flake is too large, which is not conducive to the secondary cooling and the next process. Process use
