Abstract
The utility model discloses a titanium slag electric furnace slag notch which has long service life. The slag notch comprises a passage main body which is built by magnesia bricks. The outlet end of the passage main body is provided with a slag tapping nozzle which is made of high temperature resistant and erosion resistant material. The slag tapping channel is communicated with the passage main body, forming the passage. The slag tapping nozzle has good high temperature resistant and erosion resistant performances, plays heat preservation role to the magnesia bricks, and greatly relieves the damage to the magnesia bricks resulting from thermal shock, ensuring that the service life of the slap notch is prolonged. The slag notch is suitable for the titanium slag electric furnace, submerged arc furnace, ferroalloy furnace and so on.
Description
Technical field
The utility model relates to titanium slag electric furnace, is specifically related to the titanium slag electric furnace slag notch.
Background technology
The titanium slag electric furnace slag notch plays the deslagging effect.When titanium slag electric furnace was smelted, the slag notch from the furnace wall bottom that titanium slag is interrupted flowed out.The duct of existing titanium slag electric furnace slag notch is built by laying bricks or stones by magnesia brick and is formed.Since the temperature of titanium slag up to 1800 ℃ about, have extremely strong erosiveness at the following titanium slag of this temperature, and the resistance to thermal shocks of magnesia brick is poor, at high temperature very easily corroded, so slag notch is shorter service life, has only about 10 heats by titanium slag, not only difficult in maintenance, and the cost of use height.
The utility model content
The technical problem that the utility model solved is: the titanium slag electric furnace slag notch that a kind of long service life is provided.
The technical scheme that solves the problems of the technologies described above is: the titanium slag electric furnace slag notch, comprise by magnesia brick and build the duct main body that forms by laying bricks or stones, the port of export of duct main body is provided with the mouth of being made by high temperature resistance erosion resisting material of slagging tap, and the slag releasing channel in the mouth of slagging tap is communicated with the formation duct with the duct main body.The mouth of slagging tap has slowed down the damage that magnesia brick causes because of rapid heat cycle greatly, and the mouth of slagging tap made by high temperature resistance erosion resisting material, therefore is largely increased in the titanium slag electric furnace slag notch life-span.
Further be that the mouth of slagging tap adopts carbofrax material to make.Carborundum is all good materials of a kind of high temperature resistance erosion resisting, and this lower cost for material, can effectively reduce manufacturing cost.
Further be that the mouth of slagging tap adopts silicon carbide castable is carried out integrated poured moulding at the port of export of duct main body.Adopt integrated poured moulding to make to slag tap mouth and magnesia brick to combine closely, prevent Yin Wendu cataclysm and long-time use that causing slags tap and have a loose tongue moving.
Further be, the mouth of slagging tap be shaped as cuboid.The mouth of slagging tap of rectangular shape can further improve the tight ness rating that the mouth of slagging tap combines with magnesia brick, and preventing to slag tap, it is moving to have a loose tongue.
The beneficial effects of the utility model are: the mouth high temperature resistance aggressivity of slagging tap is good, and magnesia brick has been played insulation effect, has slowed down magnesia brick greatly because of the damage that rapid heat cycle causes, and the slag notch life-span is greatly prolonged.The utility model is applicable on slag notches such as titanium slag electric furnace, the hot stove in ore deposit, ferro-alloy furnace and uses.
Description of drawings
Fig. 1 is the structural representation of the utility model titanium slag electric furnace slag notch.
Be labeled as among the figure: the mouth 1 of slagging tap, slag releasing channel 2, duct 3, duct main body 4.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Embodiment
Titanium slag electric furnace slag notch as shown in Figure 1, comprise by magnesia brick and build the duct main body 4 that forms by laying bricks or stones, the port of export of duct main body 4 is provided with the mouth 1 of slagging tap, this mouth 1 of slagging tap adopts silicon carbide castable to carry out integrated poured moulding, the mouth 1 of slagging tap after the moulding is shaped as cuboid, and its slag releasing channel 2 is communicated with formation duct 3 with duct main body 4.Wherein, slag releasing channel 2 is 80mm with duct main body 4 equal diameters.In the process of slagging tap, titanium slag is flowed through after the duct main body 4, enters the mouth 1 of slagging tap, the damage of having avoided magnesia brick to cause because of rapid heat cycle, contact with the extraordinary mouth 1 of slagging tap of corrosion resistance at the outer high temperature titanium slag of slag notch, reduced the situation that the slag notch that causes because of the titanium slag corrosion widens damage.Brought up to 200 heats more than by average 10 heats the service life of this titanium slag electric furnace slag notch, has great economic worth.
Claims (4)
