Description
Technical Field
The invention relates to the ferrous metallurgy technology, in particular to an air blowing type molten steel flow distribution device applied to double-roller thin-strip continuous casting.
Background
The twin-roll thin strip continuous casting refers to a production process for directly introducing liquid metal into two casting rolls with opposite rotating directions as crystallizers to produce thin strip steel with the thickness of less than 10 mm. Compared with the traditional thin strip production process, the twin-roll thin strip continuous casting process has the advantages of shortening the process flow, saving energy, reducing the production cost, improving the mechanical property of a strip blank and the like, so the technology is considered to be one of the most promising near-net-shape continuous casting technologies in the 21 st century.
The strip continuous casting process in the prior art is a casting and rolling process which is not only connected with the traditional continuous casting but also distinguished from the traditional continuous casting process: the main process is that after molten steel is poured into a tundish, the molten steel is distributed into a flow distributor through a water gap, and then the molten steel is poured into a molten pool enclosed by two water-cooled crystallization rollers and side sealing plates through the flow distributor, the molten steel is gradually solidified on the surfaces of the two crystallization rollers to form blank shells, and after the molten steel is completely solidified near a connecting line of the two crystallization rollers, the molten steel is rolled through the reverse rotation of the two rollers to form a compact metal band with certain thickness and width.
Therefore, a rational flow distribution system is of great importance for twin roll strip casting. The reason is that the flow distribution system directly influences the quality of thin strip products, according to statistics, when the fluctuation range of the liquid level of the molten pool exceeds +/-2 mm, longitudinal cracks can appear on a strip blank, but if the liquid level fluid area of the molten pool is too calm, the liquid level is not beneficial to updating of molten steel on the upper part of the molten pool, and the liquid level is easy to crust, so how to keep the balance between the two is a precondition for pouring qualified thin strips.
The patent disclosed by the current distributor in the prior art mainly has a three-pack structure, a two-pack structure and a single-pack form, and the three-pack structure, the two-pack structure and the single-pack form are as follows:
the distributor mainly has a three-ladle structure, namely a tundish, a transition ladle and a distributor, three steel containers are connected through large and small water gaps, the distributor is of a square structure, molten steel flows into the distributor through the water gaps of the transition ladle, and the bottom of the distributor is provided with a discharge hole.
After the field application, the flow distributor has the following defects:
1) the structure is more and complicated, and an additional transportation link of the equipment is added;
2) the installation difficulty of the intermediate transition ladle is increased due to the addition of the intermediate transition ladle, and an additional mechanism is required to be equipped during taking off and landing;
3) because the molten steel directly falls into the lower flow distributor through the narrow slit, the fluctuation in the flow distributor caused by the overlarge fall is also large, and the effect of flat turbulence is avoided.
Two package structures-this type distributor's characteristics mainly are that the middle package is constituteed with two steel container that contain of distributor, utilize the mouth of a river to link up between the two, the patent of applying for each country is many, japanese patent JP1317658 discloses a distributor, at the bottom of distributor tiling a porous refractory plate, after the mouth of a river outflow of molten steel through the middle package, at first reach on the porous refractory plate, porous plate has better flat turbulent action, and then molten steel flows into distributor bottom through the aperture, flows out to dissolving in the pond through the aperture.
After the field application, the flow distributor has the following defects:
1) although the porous refractory plate has a good turbulence leveling effect, under the casting conditions of high flow rate and high pulling speed, the flow distributor is easy to overflow due to the limited steel passing amount of the refractory plate;
2) the porous refractory plate conveys molten steel through the micropores, and when encountering micro-particle inclusions in the molten steel, the porous refractory plate forms blockage to gradually influence the throughput of the molten steel;
3) it is verified that the porous refractory plate can pass through the molten steel properly.
The two-bag structure is similar to that of the patents-CN 02283420.6 and CN200820058904.X in China, and respectively discloses a flow distributor form, the upper part of the flow distributor is of an open structure, two sides of the lower part of the flow distributor are provided with a plurality of discharge holes, and the bottom of the flow distributor is of an oblique angle or an arc shape.
However, the flow distributor still has the following defects: the liquid level fluctuation at the position is increased while the molten steel is supplied near the side sealing plate, and the solidification quality of the strip steel is easily influenced.
In addition, there are methods of controlling the position of dross by providing a slag trap in the bath and controlling the flow direction of dross by blowing inert gas into the surface of the bath, which have solved various problems of the two-ladle structure, but the results are unsatisfactory.
The single ladle structure and the flow distributor of the type are characterized in that the steel container only has a tundish and flows into a molten pool between two rollers through a nozzle. As early as 10 months in 1996, the patents of tsen steel and co-pending in his noll sa-sienoll company, based on the original conventional nozzle, propose a new type of flow distribution scheme, the arrangement of which changes the opening at the bottom of the nozzle from one to two, and at an oblique angle.
The advantages and disadvantages of the design are also obvious: simple form, low cost but difficult control of fluctuation and solidification uniformity.
In summary, various flow distributors or flow distribution systems in the prior art have more or less defects, and a new flow distribution device needs to be designed to solve the above problems.
