Casting process of aluminum alloy slab ingot

Abstract

The invention relates to a casting process of a aluminum alloy slab ingot, which is particularly suitable for co-casting the aluminum alloy slab ingot with different specifications and belongs to the production technical field of aluminum processing industry. The casting process comprises the following steps of: 1, establishing casting process parameters; 2, simulating casting; 3, confirming fusant temperature in a heat preserving furnace; 4, laying out a crystallizer; 5, casting; 6, sampling from final components; and 7, cooling aluminum liquid. The casting process of aluminum alloy slab ingot is capable of casting the aluminum alloy slab ingot with two or more than two specifications at one step, and has high production safety, low investment cost and easy operation.

Description

technical field [0001] The invention relates to an aluminum alloy flat ingot casting process, which is particularly suitable for producing aluminum alloy flat ingots of different specifications in the same casting process, and belongs to the production technology field of the aluminum processing industry. Background technique [0002] Existing casting machines generally can only produce aluminum alloy flat ingots of one specification at one casting time. There are considerable safety hazards in casting two or more specifications at one casting time, such as aluminum leakage, ingot hanging, Low liquid level and high liquid level are the most likely phenomena. At present, there is basically no casting process of aluminum alloy flat ingots with two specifications or even three specifications in the same casting time in China. The existing light alloy melting and casting workshop generally has 20 sets of crystallizers of different specifications: the thickness range is 520-640mm...

Problems solved by technology

[0002] Existing casting machines generally can only produce aluminum alloy flat ingots of one specification at one casting time. There are considerable safety hazards in casting two or more specifications at one casting time, such as aluminum leakage, ingot hanging, Low liquid level and high liquid level are the most likely phenomenon. At present, there is basically no aluminum alloy flat ingot casting process with two specifications or even three specifications in the same casting time.

The existing light alloy melting and casting workshop generally has 20 sets of crystallizers of different specifications: the thickness range is 520-640mm, the width range is 1150-2130mm, and the length of the ingot produced is up to 9150mm, and only one type can be used for each casting. Standard crystallizer casting, and many orders are very small (with test materials) or ordered according to the number of blocks required by customers, which cannot reach the minimum production capacity of casting, and in order to attract customers, production must be organized, so we can only arrange more than planned Casting several ingots has reached the minimum production capacity of melting and casting, and the over-cast ingots are backlogged at the workshop site, resulting in a large amount of metal backlog, resulting in waste of resources, increasing production costs, and causing serious damage to unit metal circulation and capital turnover. A lot of pressure
