Problems solved by technology

The furnace cover of the existing refining furnace is generally made of solid refractory materials or poured. During the use of the refining furnace, the electrodes move up and down in the electrode holes opened on the furnace cover. Electric arc drawing, due to long-term high temperature, the service life of the furnace cover is low

Abstract

The invention discloses a refining furnace which comprises an electrode, a furnace body and a furnace cover. A slag discharging port, an iron discharging port and a charging port are formed in the furnace body. The furnace cover is arranged on the furnace body and seals the furnace body, and comprises an inner furnace cover body and an outer furnace cover body, and an electrode hole for allowing the electrode to penetrate is formed in the inner furnace cover body. The electrode movably penetrates the electrode hole, and the inner furnace cover body is coaxially sleeved with the outer annular furnace cover body. The inner furnace cover body is in an inverted frustum shape, and the shape of a cavity in the outer annular furnace cover body is matched with the appearance of the inner furnace cover body. A first cooling chamber is formed in the inner furnace cover body, and a first water inlet and a first water outlet communicating with the first cooling chamber are formed in the inner furnace cover body. A second cooling chamber is formed in the outer annular furnace cover body, and a second water inlet and a second water outlet communicating with the second cooling chamber are formedin the outer annular furnace cover body. According to the refining furnace, slag is not likely to be bonded on the furnace cover, the furnace cover is easy to clean, and the service life of the furnace cover is prolonged; and the cooling effect is good, and repairing is convenient.

Description

technical field [0001] The invention relates to a smelting equipment, in particular to a refining furnace. Background technique [0002] Refining furnace is a kind of smelting equipment in the thermal processing industry, and it is mostly used for the final deoxidation and alloying process of molten steel in ferrous metallurgy. The furnace cover of the existing refining furnace is generally made of solid refractory materials or poured. During the use of the refining furnace, the electrodes move up and down in the electrode holes opened on the furnace cover. With electric arc drawing, the service life of the furnace cover is low due to the high temperature for a long time. Contents of the invention [0003] The object of the present invention is to provide a refining furnace to solve the problems of the above-mentioned prior art, make the furnace cover not easy to slagging and easy to clean, improve the service life of the furnace cover, have a good cooling effect, and fac...
