Detailed description of the invention
For further describing the present invention, below in conjunction with drawings and Examples, the present invention is described in further detail.
A kind of spray of the pressure for amorphous band pressure band processed bag shown in Fig. 1-7, mainly to store molten steel and use for when band spray, it comprises spray pack housing 10 and the feeding unit to transportation of molten steel in spray bag, described spray pack housing 10 inner bottom parts are provided with the drain cavity 12 of big up and small down terrace with edge shape, described drain cavity 12 is connected with the injection cavity 13 arranging thereunder, and the bottom of described injection cavity 13 is connected with nozzle 50.
The top of described housing 10 is provided with sealing plate 30, and one end of described sealing plate 30 offers the passage 31 being connected with suction nozzle, imports gas while being convenient to spray band; The other end offers through hole 32, and described feeding unit comprises and is placed in the mozzle 20 that this through hole 32 is hollow form.

Pressure for amorphous band pressure band processed spray bag of the present invention, it is a complete totally enclosed space, the molten steel flowing in spray bag is not directly contacted with air, and the inner pressure that has all the time 0.035~0.04MPa left and right in the time of work of spray bag, make molten steel become to be greater than atmospheric pressure in spray bag internal rows, cause molten steel better from nozzle, to extrude in spray bag, thereby reach the effect that density is high, thickness is even, burr are few.
When spray band, molten steel enters in spray bag through mozzle from drain funnel, molten steel is because dead weight flows to unique outlet---nozzle in spray bag, open a width according to manufacturing technique requirent in nozzle installation site and be about 1mm, length is the openning between 10~50mm, the normal working temperature of molten steel is 1400~1500 DEG C, it runs into the copper roller directly contacting with it after flowing out from nozzle, copper roller inside is hollow structure, and pass to cooling water always, surface temperature is generally between 20~30 DEG C, in the time that the molten steel of high temperature runs into the copper roller of low temperature, moment just condenses and becomes solid, because opening is flat, so noncrystal after moulding is just flat band shape.
When molten steel pour into spray bag reach a certain height as Fig. 1 as show liquid level A time, just stopped down molten steel, at this time common spray bag just can only be extruded from nozzle by the deadweight of the interior molten steel of bag, because weight is limited, so the strip surface density contrast spraying.And the present invention is provided with passage in the sealing plate left side of spray bag, in the time that molten steel reach a certain height, (be inert gas because of nitrogen by adding air pressure in suction nozzle at the nitrogen of 0.035~0.04MPa left and right, after adding, can not cause chemical reaction to molten steel), at this moment the pressure of nitrogen adds the deadweight of molten steel, when molten steel is extruded from nozzle, can form than common band processed and have more the pressure of nearly one times, thereby reach good strip density, (common strip density is at 6~7g/cm 3), spray by pressure the strip density packing out and can reach 7.5cm 3above.
In spray bag, it is the space of a sealing, all the time there is certain air pressure inside, can avoid like this as common spray bag because the time of falling steel molten steel dark, shallow inconsistent, cause the strip density of extruding from nozzle too low, thick, thin inhomogeneous, thereby directly affect the performance of band, cannot ensure the high-quality of product.And common spray is while wrapping in molten steel lower than the position of spray bag half, because the weight of molten steel self is inadequate, the band of ejection is scratch tape substantially, and pressure spray bag is because have all the time air pressure in airtight bag, so the liquid level of molten steel is low again, because there is the reason of pressure, thereby ensure that the band of its ejection has a good quality in the same old way.
