Continuous casting and rolling process for producing 3005 aluminum-plastic strip blank

Abstract

The invention relates to the aluminum processing industry, in particular to a continuous casting and rolling process for producing a 3005 aluminum-plastic strip blank. In the process, an aluminum melting furnace, a heat preserving furnace, an online refining device, a two-stage filtering box, a continuous casting and rolling unit are used in the production method. The process method comprises the following steps of: 1) preparation; 2) feeding; 3) melting and stirring; 4) drossing and sampling for analysis; 5) degassing and refining, standing and heat preservation; 6) online melt treatment; 7) continuous casting and rolling; 8) reeling and cutting; and 9) checking. The continuous casting and rolling process in the invention has the advantages that an 80% electrolytic aluminum liquid is adopted in the production process, the burning loss of aluminum is reduced to be below 1.5%, and the unit consumption of gas is reduced to be below 80Nm<3>/tAl, thus both the burning loss of aluminum and the energy consumption are reduced by 50% as compared with a casting and rolling method which adopts aluminum ingot for remelting to produce the 3005 aluminum-plastic strip blank, and the production yield is up to over 99%. The continuous casting and rolling process method for producing a 3005 aluminum-plastic strip blank in the invention is applicable to the aluminum and aluminum alloy casting industry at home and abroad.

Description

technical field [0001] The invention relates to the aluminum processing industry, in particular to a continuous casting and rolling process for producing 3005 aluminum-plastic strip blanks. Background technique [0002] Domestic 3005 aluminum-plastic strips are generally cast-rolled billets, and the final rolled thickness is generally greater than 0.2mm. The production method of the casting billet is: let the molten aluminum pass through a set of devices to guide the "roll gap" formed between the two rolls, and after the forced cooling, crystallization and deformation of the two rolls, the thickness is 6mm ~ 8mm. of cast-rolled coils. During the casting and rolling process, the molten aluminum is crystallized by the rapid cooling of the two rolls in the narrow gap between the two rolls, and the solidified billet is rolled and deformed by the two rolls to a certain extent at the same time, and the obtained cast-rolled sheet The internal structure of the crystal belongs to t...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a double-drive tilting type in view of the shortcomings in the current production method of 3005 aluminum-plastic strip that the aluminum ingot for remelting needs to be remelted, the burning loss of aluminum is relatively large, and the energy consumption is high.
