Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Referring to FIG. 1 , the electric arc furnace of the present invention includes a molten pool 10 formed by a furnace body and electrodes inserted into the molten pool 10 . The furnace body is closed, and its top is provided with a feed inlet 15 extending into the molten pool 10, and the bottom of the molten pool 10 is provided with a slag outlet 11 and a taphole 12 extending out of the furnace body. The volume ratio of molten pool 10 is 1-1.5MVA / t. The power is large, and the slag-iron mixture can be melted quickly; continuous operation, the feeding device cooperates with the separate slag outlet 11 and iron outlet 12, and continuous smelting production can be realized.

[0014] Referring to Fig. 1, the feeding port 15 is connected with the continuous feeding device, and the feeding port 15 is fixedly arranged on the furnace cover constituting ...

Abstract

This invention discloses a kind of electric-arc furnace in order to make it work continuously and smelt quickly, primely satisfy the demand of low-grade smelt, or large quantity of slag, or the iron-bearing material having the special request in discharging slag. It includes molten pool (10) formed by the stove body and the electrode inserted into molten pool (10). The body of the furnace is sealed, and the feed head (15) inserted into molten pool (10) is installed at the top of it. There are a slag hole (11) and a taphole extending and coming out of the furnace at the bottom of the molten pool (10). Power transformer and the volume of the molten pool (10) are in a ratio of 1-1.5 MVA / t.

Description

technical field [0001] The invention relates to an electric arc furnace, in particular to an electric arc furnace which is particularly suitable for smelting low-grade iron-containing materials. Background technique [0002] With the rapid development of the iron and steel industry, the supply of iron-containing raw materials is becoming increasingly tight. The treatment of iron-containing waste and the rational application of low-grade ore are particularly important. For the utilization of low-grade iron-containing raw materials, it is possible to use them directly in the iron and steel production process without any treatment, such as adding low-grade iron-containing raw materials or iron-containing scraps in the process of blast furnace ironmaking or converter steelmaking, but there is no doubt It will reduce the technical indicators of production, especially for some multi-element composite symbiotic iron-containing raw materials, such as vanadium-titanium magnetite, et...
