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...

Examples

Embodiment 1

[0031] The aluminum alloy flat ingot casting process of the present embodiment refers to the appended Figure 1-2 , casting 3 aluminum alloy flat ingots with a specification of 560×1310×8400, and 2 aluminum alloy flat ingots with a specification of 620×1150×8200. The specific process is as follows:

[0032] 1. Check devices and instruments

[0033] Check all safety devices and ensure that all instruments are functioning properly;

[0034] Formulate casting process system

[0035] First, compare the casting process parameters of ingots of different specifications cast in the same casting order, namely casting speed, water flow rate, secondary water valve, control pin opening degree, and casting transition section, and find out the same process parameters and different ones by comparison. Process parameters, among them, the casting speed shall be subject to the slowest process of the same casting time, the water flow rate shall be subject to the maximum water flow rate of the ...
