Description
Technical Field
The invention relates to a casting and rolling manufacturing technology of metal alloy materials, in particular to a double-roller casting and rolling device of metal alloy strips.
Background
At present, the production process of the non-ferrous metal strip comprises a hot rolling process and a casting and rolling process, the casting and rolling process is short in process, low in production cost and more popular in application. Casting and rolling, also known as ingot-free rolling, are combined forming methods of casting methods and rolling methods. The casting and rolling process is one technological process of casting and rolling molten metal liquid into semi-finished blank or finished product, and features that the molten metal liquid is crystallized, solidified and hot rolled in two rotating rolls with liquid cooling system in short time to form one integral, and the metal material product is produced through casting and rolling.
The casting and rolling equipment mainly comprises a casting nozzle trolley and a roller, wherein the roller mainly comprises a roller body, a roller sleeve and the like. In the working process, the roller continuously rotates, so that the surface of the roller sleeve is subjected to periodic cycle alternating action of cold and hot loads, the roller sleeve forms an alternating temperature field, corresponding thermal stress is generated, and the peripheral surface of the roller sleeve is cracked. As the working time increases, the number of fracture cracks on the peripheral surface of the roll shell gradually increases and expands. When the peripheral surface of the roller sleeve reaches certain damage, the roller sleeve needs to be dismounted for turning and polishing, so that the service life of the roller sleeve is greatly reduced.
The non-uniformity of the sleeve temperature also affects the effective heat exchange coefficient between the non-ferrous metal and the sleeve, thus varying the thickness of the non-ferrous metal strip rolled. More importantly, part of active nonferrous metals, such as aluminum, are easy to react with oxygen in the air to form an oxide film under natural environment, and the oxidation reaction is quicker under high-temperature environment. Due to the inherent characteristics of the twin roll casting process, the molten metal in the gap between the nozzle and the rolls is exposed to air which inevitably oxidizes and forms an oxide film. Most non-ferrous metal oxides are hard and brittle impurities, and particularly, the oxide films which are not naturally formed in the casting and rolling process have the characteristics of discontinuity, randomness and persistence. With the rotation of the roll with the uneven temperature, which has cracks on the surface, the oxide film is more easily brought to and remained on the surface of the metal strip by the roll sleeve, thereby forming holes on the surface of the metal strip or causing strip breakage, and causing adverse effects on the quality of the surface of the metal strip product.
In order to solve the technical problem that the roller sleeve has uneven temperature, ZL00813911.3, name: continuous casting rolls of metal strip with cooling circuits that periodically reverse the direction of flow of the cooling fluid in the roll body increase the cost of roll manufacture and also place higher demands on the associated equipment. ZL00126702.7, name: the utility model provides a casting roll core, this patent sets up square dashpot between water inlet and cooling water tank, and the cooling water flows into the apopore again to assembling the groove by the dashpot, and then increases cooling medium's area of contact between core and the roller shell, but the temperature of its roller shell still exists very big inequality. The above methods all reduce the temperature difference in the roller sleeve to different degrees, but the effect is general or the cost is greatly increased.
