Most of double-roller continuous casting machines adopt solid side seal material.These side seal materials have boron nitride, aluminium oxide, silicon nitride, graphite, quartz etc.The subject matter of using solid side seal material to exist has: the cost height, and it accounts for about 20% of totle drilling cost; Life-span is low, the incompatibility need of industrial production; Thermal insulation is poor, makes the temperature field skewness of bandwidth direction, thereby causes the defective of casting strip quality; Side seal is not tight, and the slit between molten steel easy inflow side shrouding and the roller end face makes the edge, Cast Strip produce overlap, burr or is torn, and forms irregular limit portion, has a strong impact on the quality of band steel.
Existing document comprises side seal board, electromagnetic side sealing and the combination side seal that is combined by both relevant for the report of strip casting mill lateral seal; Also have by regulating side seal board, regulate the report of strand width; Relevant for the report of distolateral seal along the vibration of casting direction; Also relevant for liquid core of continuous casting billet casting and the report of gently depressing the technical progress aspect.Though in the above-mentioned report lateral seal is had the different improvement of all angles, all be difficult to break away from the problem that produces big friction and edge crust between molten steel and the lateral seal, thus influence casting quality.
Summary of the invention
Thereby, the invention provides a kind of strip casting mill with closed type and vibration side seal that can greatly alleviate the friction problem between molten steel and the casting and rolling machine at the problem that has big friction influence casting quality between the side shield of present casting and rolling machine and the molten steel.
Strip casting mill with closed type and vibration side seal of the present invention, it comprises the horizontal roller 1 that pair of parallel arranges, the side seal board 2 that is arranged on horizontal roller 1 two ends, be provided with side roller 3 below the described side seal board 2, the axis of described side roller 3 contacts with adjacent two horizontal roller 1 with axis normal and its edge of horizontal roller 1, in the casting and rolling machine of this structure, horizontal roller 1 is a drive roll, side roller 3 is a driven roll, horizontal roller 1 drives 3 rotations of side roller by friction, when realizing sealing, again can be owing to the rotation of side roller is avoided the molten steel crust or had big friction;
Preferably, the side seal board 2 of casting and rolling machine vibrates by frequency 100～300Hz, and oscillating plate and molten steel contact site form the base shell, and vibration can make the base shell produce relative slip with oscillating plate, and the base shell glides with the crystallization molten steel and do not produce bonding with oscillating plate.
In Casting steel strip equipment, use casting and rolling machine of the present invention, molten steel is slided and unlikely bonding with side seal board at side seal board edge crust, side roller 3 forms closed pass with horizontal roller 1, the base shell that moves down from side seal board plays the effect of gently depressing through side roller 3, thereby make whole made-up belt in above-mentioned closed pass, have the identical speed that moves down, thereby improved the surface quality of made-up belt, especially quality of edges.Thereby eliminated the limit portion crackle of made-up belt casting, improved lumber recovery, accomplished the strip base casting of practical significance, therefore be beneficial to and apply.

The specific embodiment
Present embodiment is a kind of strip casting mill with closed type and vibration side seal, with reference to Fig. 1～Fig. 4, it comprises the horizontal roller 1 that pair of parallel is arranged, be arranged on a pair of side seal board 2 at horizontal roller 1 two ends, be provided with side roller 3 below the described side seal board 2, the axis of side roller 3 contacts with adjacent two horizontal roller 1 with axis normal and its edge of horizontal roller 1, be understandable that, the lower end of side seal board 2 and horizontal roller 1 and side roller 3 all are to contact and profile is close-fitting, be appreciated that simultaneously the edge of side roller 3 and the profile of adjacent two horizontal roller 1 also are close-fitting, like this, closed type when the side roller 3 of pair of parallel constitutes casting with the horizontal roller of pair of parallel 1, horizontal roller 1, side seal board 2 and side roller 3 have promptly been formed a molten bath.
Can know clearly, the present invention is with respect to prior art, main innovative point is to be provided with the side roll structure and since when casting the side roller together rotate with horizontal roller, therefore eliminated present side seal board molten steel produced the problem that big friction and steel band edge crust.
Those skilled in the art can know that horizontal roller 1, side seal board 2 and side roller 3 all are water-cooling structure, and the intensity of cooling of horizontal roller 1, side seal board 2 and side roller 3 all is complementary.Therefore in casting process, the horizontal roller 1 that is arranged in parallel is two driven rollers, side roller 3 is two driven rolls, side roller 3 is by the friction driven rotary of horizontal roller 1, at this moment, at the molten steel of side seal board 2 coolings, gently depress by side roller 3, prevent " triple point " district crust, therefore can make the steel strip surface quality good.
Be appreciated that, the concrete thickness of steel band is to be determined by the axial length of side roller 3 (side roller thickness), therefore in the practical application, the side roller of different length can be set according to the needs of steel band different-thickness, but all will guarantee closely cooperating and can realize relative rotatablely moving between side roller and the horizontal roller.
