Description
Technical Field
[0001] The utility model belongs to the technical field of casting and rolling mills and relates to a titanium wire feeding device for casting and rolling mills. Background Art
[0002] The aluminum alloy twin-roll casting and rolling machine is a process in which the molten liquid aluminum alloy after being refined in a static furnace is passed through a static furnace mouth, a front box nozzle, and casting and rolling rollers that rotate towards each other and have circulating cooling water inside, so that the liquid aluminum alloy is crystallized and produces a certain deformation rate, thereby realizing the process of casting and rolling the aluminum alloy from the molten liquid metal into plates, and then forming cast-rolled coils after cutting and coiling.
[0003] In order to improve the quality of cast strip and obtain fine grains, the commonly used process is to continuously add aluminum titanium boron wire (hereinafter referred to as titanium wire) refiner in the flow channel of the casting and rolling machine; the titanium wire refiner is extruded into φ8-12mm wire, and then coiled into a coil for use; after entering the high-temperature aluminum alloy melt, the titanium wire is melted and mixed with the aluminum alloy melt, which plays a role in refining the grains when forming the cast strip.
[0004] The titanium wire feeding device is composed of a wire unwinding rack, a titanium wire slip alarm device, and a titanium wire feeder. The titanium wire reel is placed on a wire unwinding rack designed with bearings. The titanium wire feeder is driven by an AC variable frequency motor and a grooved feed roller is driven by a reducer. A clamping roller device is provided above the feed roller, which can effectively bite the titanium wire and smoothly feed it into the flow channel. In addition, different alloy grades and plate widths require different titanium wire feeding speeds. The conventional titanium wire feeding device feeds the titanium wire into the aluminum alloy melt from the upper side (side) of the flow channel. The position of the titanium wire entering the flow channel is fixed. The mixing of the titanium wire with the aluminum alloy melt after melting cannot be guaranteed to be uniform.

In recent years, with the increasing demand for battery foil products, more stringent requirements have been placed on the quality of the cast strip used as battery foil raw materials.
