Teapot nodulizing packet

Abstract

The invention discloses a teapot nodulizing packet which has simple structure, convenient use and high utilization rate of nodularizer and can also be used as a pouring packet. The teapot nodulizing packet comprises a packet body (6), and the inner bottom of the packet body (6) is provided with a dike (5) which divides the bottom of the packet body (6) into a feed chamber (2) and a nodulizing chamber (4). The teapot nodulizing packet is characterized in that the upper part of the packet body (6) is provided with a single sealing side cover (7), one side of the packet body (6) is provided with a pot nozzle (1), and the lower part of the packet body (7) is provided with a molten iron inlet and outlet port (3) communicated with the pot nozzle (1). The feed chamber (2) is communicated with the pot nozzle (1) through the molten iron inlet and outlet port (3). The invention has simple and reasonable structure, and nodulizing and pouring are carried out in one packet. During a nodulizing reaction, the absorption rate of magnesium can reach more than 85 percent, the addition quantity of the nodularizer is reduced, the labor intensity is lightened, the working environment is improved, and the air pollution is reduced; meanwhile, the tapping temperature of molten iron is also reduced, so that production cost is lowered.

Description

Technical field: [0001] The invention relates to a spheroidizing device in the casting production process, in particular to a teapot-type spheroidizing bag. Background technique: [0002] At present, most of the spheroidizing methods with a light amount of single-pack spheroidizing molten iron adopt open-mouth spheroidizing treatment, resulting in a large amount of dust during spheroidizing, a large amount of nodulizing agent, fast spheroidizing decline, and a large amount of molten iron splashing, causing environmental pollution. , Increased production costs, unstable product quality and increased labor intensity of operators. At the same time, since most of the spheroidizing devices used in the spheroidizing treatment are special spheroidizing reaction ladles, the molten iron needs to be subcontracted after spheroidizing, and the spheroidized molten iron is poured into a teapot-type pouring ladle for subsequent pouring. degradation problem. The patent number is 200620162...

AI Technical Summary

Problems solved by technology

Since the feed port during spheroidization and the pouring port during pouring are set separately, its structure is complex and inconvenient to use; moreover, the spheroidizing chamber is directly connected to the pouring port, and it is easy to cause magnesium vapor to escape during spheroidizing. At the same time, the sprue is an open ladle nozzle, which has a large contact area with the air, and the temperature of the molten iron drops quickly
