Abstract
The utility model discloses a smelting furnace with a double-molten channel structure for phosphor and copper, which comprises a furnace body. Smelting molten channels are formed in the furnace body; each smelting molten channel comprises a heating body arranged in the middle and two molten channel cavities annularly arranged around the heating body; a refractory layer and a cooling layer are arranged among the molten channel cavities and the heating body. Due to the adoption of the double-molten channel structure, the current density can be increased compared with a homalographic single molten channel, so that the current density of the molten channels can reach 9-12 A/mm2, and the current density of a coil can reach 2-2.5 A/mm2, thereby improving the electro-thermal efficiency of the heating body; and because the cross section of each molten channel cavity is round or elliptical, the heat transmission capacity is improved, and the channel blocking phenomenon is effectively prevented. The utility model also can be used in the smelting production process of bronze, brass and other metal products. Because the energy consumption is reduced, the smelting furnace facilitates the development of low carbon economy and has good economic benefit and social benefit for popularization and application.
Description
Technical field
The utility model relates to a kind of structure of smelting furnace, more specifically is meant a kind of smelting furnace structure of suitable phosphor-copper.
Background technology
In the prior art, smelting furnace is the indispensable firing equipment that copper product carries out continuous casting processing, normally adopt the mode of line-frequency induction heating, and most employing is built-in heating arrangement, promptly coil and iron core calandria as the line-frequency induction heating, place in the middle of the smelting furnace, the copper base is placed in the channel cavity, inductor as the line-frequency induction heating, carry out liquefying behind the eddy-current heating, between the channel of smelting furnace and calandria (comprising coil and iron core), can be provided with a thermostabile bodies, the skin of this thermostabile bodies is the refractory layer that is made of exotic material, and internal layer then is water-cooled cooling layer, but because the power that single channel can adopt is limited, but when adopting excessive power, then damage whole furnace construction easily.Because the power that single channel can adopt is limited, thereby limited the production efficiency of smelting furnace.
Based on the defective of above-mentioned prior art, our company's technical research staff development a kind of smelting furnace that comes out with two channel structures.
The utility model content
The purpose of this utility model is to provide a kind of smelting furnace with two channel structures for overcoming the deficiencies in the prior art.
Technology contents of the present utility model is: the smelting furnace that has two channel structures that is used for phosphor-copper, comprise body of heater, be provided with the melting channel in the described body of heater, it is characterized in that described melting channel comprises the calandria in the middle of being located at, and be located on calandria two channel cavitys all around, be provided with flame retardant coating and cooling layer between described channel cavity and the calandria.
Its further technology contents is: described calandria comprises coil and iron core, be that the melting channel comprises outermost channel cavity, and the flame retardant coating (be called not only fire clay), cooling layer (but also being called water jacket), the calandria (comprising coil and iron core) that are positioned at channel cavity center zone successively.
Its further technology contents is: the cross sectional shape of described channel cavity is for circular or oval.
Its further technology contents is: described cooling layer is provided with water cooled pipeline or air-cooled pipeline.
Its further technology contents is: described body of heater is provided with the insulation channel in the side of melting channel.
The utility model beneficial effect compared with prior art is: the utility model is owing to adopt the structure of two channels, with single channel of homalographic mutually specific energy strengthen current density, make the current density of channel can reach 9～12A/mm
2, coil current density reaches 2～2.5A/mm
2, can improve the electrothermal efficiency height of calandria; Because the cross section of channel cavity (being called the induction channel again) has been improved the transmission capacity of heat energy and has been effectively prevented stifled ditch phenomenon for circular or oval.The utility model can also be used for other melting production technology as metallic articles such as bronze, brass.Because the current density of channel can be bigger, the electrothermal efficiency height of calandria, the life-span of heater is long, thereby has reduced the consumption of energy, helps developing low-carbon economy, and of the present utility model applying has good economic benefit and social benefit.
