Embodiment 1

[0039] Such as figure 1 As shown, it is the first basic structure of the heating device at the bottom of the liquid metal container - the bottom electric heating filter box, the main body is a refractory material box 1, and the bottom of the box has a cavity 2, and the heating chamber 3 is embedded in the cavity to generate heat The body 4 is placed in the heating chamber, the heat conduction plate 5 is placed above the heating chamber, and the filter plate 9 is placed in the box above the heat conduction plate. The heating element preheats the filter plate in advance, and the aluminum melt 6 enters the box body through the aluminum melt inlet 7, passes through the filter plate to remove dross, and is discharged from the aluminum melt outlet 8.

Embodiment 2

[0041] Such as figure 2 As shown, it is the second basic structure of the heating device at the bottom of the liquid metal container - launder heated at the bottom, smaller static furnace, holding furnace and various refining devices outside the furnace. The main body is a refractory material box 1 , The bottom of the box has a cavity 2, the heating chamber 3 is embedded in the cavity, the heating element 4 is placed in the heating chamber, and the heat conducting plate 5 is placed above the heating chamber.

Embodiment 3

[0043] Such as image 3 As shown, it is the third basic structure of the heating device at the bottom of the liquid metal container - a larger static furnace, a holding furnace and a refining device outside the furnace. The main body is a refractory material box 1, and the bottom of the box has two The cavity 2 and the heating chamber 3 are embedded in the cavity, the heating element 4 is placed in the heating chamber, and the heat conducting plate 5 is placed above the heating chamber.

Abstract

This invention relates to a device used for preheating, warming and insulating fining vessel in processing non-ferro metals, which comprises a vessel used for filling liquid metal, a heating room inserted in the bottom of the vessel, a heater set in the heating room and a heat conducting board. The heat conducting board separates the heating room and said vessel, and the top connects metallic flux, the lower supplies heat, by which to heat liquid metal. The device has high calorific efficiency, and can control temperature; in addition, the heater can be changed freely without interrupting operation.

Description

Technical field: [0001] The invention relates to the heating technology of liquid metal, and in particular provides a device for liquid metal, especially aluminum melt transmission, for heating, heat preservation or container preheating of liquid metal in the refining process outside the furnace. Background technique: [0002] In the process of aluminum melt transmission and refining outside the furnace, some equipment needs to be preheated slowly and evenly to a temperature close to the aluminum melt before contacting with the aluminum melt; in the process of aluminum melt transmission and purification, the temperature It must be kept within the range of process requirements; heat preservation is required in intermittent fashion for the next round of operation. The heating methods commonly used at present mainly include the following types: [0003] 1. Flame heating. Use combustible gas or oil as fuel, and use nozzle fire to directly act on the part to be heated. This me...
