Abstract
The utility model provides a molten slag chute for a metallurgical furnace, which comprises a chute body and copper pipes; more than one group of U-shaped copper pipes are arranged in the chute body; the copper pipes are prefabricated in the chute body for forming in chute casting; each group of copper pipes are provided with refrigerant inlets and refrigerant outlets, and serve as an independent cooling system; refrigerants in the copper pipes adopt circulating water, compressed air or other mediums; and internal threads or flanges are prefabricated at the inlet ends and the outlet ends of the copper pipes to prolong the service life of the chute. The utility model has the advantages that the continuity of industrial large-scale production is improved, the energy consumption of the smelting production department is reduced, the labor intensity is reduced, and the cost is saved.
Description
Technical field
The utility model belongs to field of metallurgy, relates to the device that slag that a kind of metal produces in the metallurgical production process is realized continuous blow-down.
Background technology
The slag chute that uses in the nonferrous metallurgy field at present adopts the copper or solid chute of cast steel usually, and high temperature washes away and chemical erosion makes the service life of this chute often very short, all is forced to mostly change in 3 to 5 weeks.Because the resistance to elevated temperatures of copper chute is poor, as the slag temperature of copper metallurgy, be controlled between 1200-1250 ℃, and the fusing point of copper is 1083 ℃, is washed away damage by scorification so soon; And the chute of steel is met the metallic compound contain sulphur and chemical reaction at high temperature takes place is damaged (as FeO+Cu2S=FeS+Cu2O).Changing a chute needs the working time more than six hours just can finish at least, greatly reduces rate when producing like this, has increased the production unit energy consumption.
In addition, the fritting body slag that is bonded in the chute surface is not easy cleaning, and labour intensity is very big, even must bring serious restriction for continuous discharging slag and suitability for industrialized production with mechanical vibrator, removing.
Summary of the invention
The purpose of this utility model is to adopt the mode of the built-in copper pipe cooling of copper cell body to solve the difficult problem that prior art exists, and a kind of metallurgical furnace slag chute is provided.
The technical scheme that the utility model adopted is: 1, a kind of metallurgical furnace slag chute, form by chute body and copper pipe, it is characterized in that having in the chute body 1 group of above U type copper pipe, it is prefabricated when copper pipe is the chute casting to the interior moulding of cell body, copper pipe is S type or other suitable type shape, and every group of copper pipe all is provided with refrigerant and imports and exports, and is cooling system independently, the copper pipe refrigerant is recirculated water or compressed air or other medium, prefabricated internal thread of copper pipe entrance end or flange.
Compared with prior art, the beneficial effects of the utility model have: because refrigerant is lowered the temperature and the marriage of surface condensation protective film, prolonged the service life of chute; Can not influence rate when producing because of the damage maintenance of chute, improve the continuity that industrial scale is produced, reduce smelting production unit energy consumption; Reduced labour intensity, when deslagging finishes, only need an operative employee gently the slagging scorification film on ramming chute surface will come off voluntarily, reduced manual labor, do not using mechanical removal; Economize on the use of funds, can not change chute because of frequent casting increases production cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is cell body among the figure, and 2,3 is copper pipe.
The specific embodiment
A kind of metallurgical furnace slag chute, form by chute body 1 and copper pipe 2 and 3,1 group of above U type copper pipe 2,3 is arranged in the chute body 1, prefabricated moulding in the cell body 1 when copper pipe 2,3 is cast for chute, every group of copper pipe 2,3 all is provided with refrigerant and imports and exports, be cooling system independently, copper pipe 2,3 refrigerants are recirculated water or compressed air or other medium, copper pipe prefabricated internal thread of 2,3 entrance ends or flange.
Because the heat transfer rate of copper is very fast,, can suppresses the chute temperature effectively and can not cross and make its temperature be higher than 850 ℃ with the slide of high-temperature slag by the cooling medium of copper pipe circulation.
Because cooling effect chute surface can adhere to one deck low temperature slag blanket film, be like this have metal oxide with slag discharge also not can with chute generation chemical reaction.
Make ramming gently slightly with drill rod, slagging scorification will come off voluntarily.
Compare the service life of four different chutes:
Claims (4)
1. a metallurgical furnace slag chute is made up of chute body and copper pipe, it is characterized in that having in the chute body 1 group of above U type copper pipe.
