Embodiment Construction

[0041] Such as figure 1 , figure 2 As shown, the present invention is composed of a coil 1, an iron core 2, a yoke 3, a bearing 4, a slip ring 5, a transmission wheel 6, a main shaft 7, a bracket 8, a rectification system and a drag system, wherein the rectification system is connected to the slip ring , the drag system is connected to the transmission wheel, which is not shown in the figure.

[0042] The coil and the iron core are two groups, which are installed on the plane of the circular mounting plate, that is, the yoke iron 3 . The plane of the yoke and the main shaft are installed perpendicular to each other. The main shaft is installed on the bracket 8 through a set of bearings, the collector ring is installed in the middle of the main shaft, the positive and negative poles of the rectified power supply of the rectification system are connected to the collector ring 5, and the two excitation coils of the agitator are connected to the collector ring through wires. I...

Abstract

The invention discloses a bottom-mounted electromagnetic stirrer used for a direct current (DC) electric-excitation melting furnace, consisting of an exciter coil, an iron core, a yoke iron, a collector ring, a mainshaft, a bracket, a rectifier system and a trailing system. The electromagnetic mixer is mainly characterized in that a DC power supply supplies the power to the exciter coil, namely, the magnetic field source of the stirrer is provided by a DC electromagnet consisting of a magnetic pole which consists of the iron core and the coil with DC. The stirrer has low material cost, the magnetism is not affected by the environmental temperature, the coil can be replaced during the malfunction, and therefore, the mixer has more advantages than an electromagnetic stirrer working at low frequency and a permanent magnetic mixer which uses the permanent magnets.

Description

Technical field: [0001] The invention relates to a bottom-mounted electromagnetic stirrer for a smelting furnace, in particular to a bottom-mounted electromagnetic stirrer for a smelting furnace with DC excitation. Background technique: [0002] In 2007, the output of non-ferrous metal primary aluminum in my country has reached 12 million tons, an increase of 28.34% compared with 2006, and the output ranks first in the world. [0003] In most cases, non-ferrous metals are smelted in reverberatory furnaces. For smelting furnaces using fuel oil or gas, it is necessary to use a stirring process to solve the following problems: [0004] 1. Melting efficiency and energy saving [0005] The melting speed of the furnace is an important assessment index. Generally, the melting speed of ingots, block materials, bars and packing materials is slow, which affects the operation rate; slow melting speed is not good for burning loss and energy consumption, so the stirring process is gen...
