Embodiment Construction

[0035] A kind of Al-Ti-C wire refiner is used to produce double-zero aluminum foil wool, and the mass fraction of alloy elements in the aluminum foil wool is as follows:

[0036] Its Fe:Si is between 4.3~5.3:1.

[0037] Among them, the preferred scheme is: Fe: 0.35~0.45%; Si: 0.08~0.12%

[0038] Its preparation includes the following process flow: material preparation→batching→feeding→melting→stirring→primary refining in smelting furnace (powder injection refining with argon gas)→slag removal→sampling→component adjustment→secondary refining in smelting furnace (using carbon tetrachloride Refining)→slag removal→converter→one-time refining in static furnace (refining with carbon tetrachloride)→intensified refining in static furnace (argon refining every 2 hours)→add Al-Ti-C wire master alloy fine online Chemical agent→Ar on-line degassing→Filter box dual-channel dual-stage foam ceramic filter plate filtration (the upper filter plate mesh is 30PPI and the lower filter plate mesh...

Abstract

The invention relates to a light gauge aluminum foil woolen produced with AL-Ti-C wire refiner and a preparation method. The iron-silicon rate of the woolen ranges between 4.3-5.3. The process of the preparation technology is sequentially as follows: material preparation, batching, feeding, melting, stirring, primary refining of a smelting furnace, drossing, sampling, ingredient adjustment, secondary refining of the smelting surface, drossing, converter, primary refining in a holding furnace, intensified refining in the holding furnace, online addition of AL-Ti-C wire intermediate alloy refiner, Ar online degassing, filtration, continuous casting into 7.0-7.5mm cast rolling plates, cold rolling, high-temperature homogenizing annealing of a primary sheet strap, cold rolling, trimming of a rereeling machine, cold rolling, intermediate annealing of a secondary sheet strap, cold rolling to 0.26-0.32mm, trimming of the rereeling machine, and packaging. The cost is low, the quality is stable, the calendaring of the aluminum foil and grain refining are good in effect, and the probability of generating pinholes is low during production.

Description

technical field [0001] The invention relates to a double-zero aluminum foil wool produced by using an Al-Ti-C filament thinner and a preparation method. The invention belongs to the technical field of aluminum foil processing. Background technique [0002] At present, the main production methods of double-zero aluminum foil wool are hot-rolled aluminum foil wool, electrolyte direct continuous casting and rolling aluminum foil wool and aluminum ingot remelting continuous casting and rolling aluminum foil wool. Among them, the hot-rolled aluminum foil wool production technology mainly produces aluminum foil wool through the multi-pass large-deformation hot-rolling method. This method has high investment costs, a large plant construction area, and slow results, but the product quality is very stable; direct continuous casting and rolling of the electrolyte is the use of 40~60% cold material and intermediate alloy refiner to produce aluminum foil wool. Compared with the former,...
