Problems solved by technology

In addition, in general, in the rolling of high-purity materials called 29, 39, and 49, whose aluminum purity exceeds 99%, 99.9%, and 99.99%, significant condensation occurs to hinder lubricity, or a large amount of Abrasive powder that hinders productivity improvement
[0007] Therefore, a sufficient rolling limit cannot be obtained by adding conventionally known oil-based agents, so measures are taken to increase the amount of oil-based agents added or to reduce the rolling speed or reduction ratio for rolling.
However, by increasing the oily agent, the following problems will occur: the occurrence of stains during annealing, the occurrence of slippage between the work roll and the rolled material, the uneven gloss of the rolled plate surface, and the increase in the amount of abrasive powder. Deterioration of the operating environment due to increased odor of the oil agent, increase in the cost of rolling oil, etc.
Abrasive powder itself is easy to rust and absorbs oil such as anti-rust oil, so the oil film will be lost and rust will occur
In addition, when abrasive powder or dust remains on steel sheets used in automobile bodies, etc., problems such as damage during press molding may occur.

Embodiment 1

[0314] In this example, a test was performed as an aluminum rolling oil.

[0315] The base oils in Table 1 were blended with butyl stearate, lauryl alcohol, and oleic acid as oily agents in the amounts shown in Table 2 to prepare metalworking oils.

[0316] Next, the aluminum rolling test, the determination of the odor, and the oil agent removal test were carried out with respect to the obtained processing oil.

[0317] All the results are described in Table 3 below.

[0318] Test method for rolling process:

[0319] Using aluminum (JIS A1050; thickness 0.15 mm, width 78 mm), rolling was performed at a rolling speed of 250 m / min and a reduction ratio of 35%, and the load required for processing was measured. When the required load is small, the workability becomes good, which is preferable.

[0320] Determination method of odor:

[0321] The odor was judged in the state which heated the sample oil to 40 degreeC.

[0322] 10 judges made the evaluation, an...

Embodiment 2

[0334] In this example, a test was performed as an aluminum heat sink processing oil.

[0335] The base oils in Table 1 were blended with butyl stearate, lauryl alcohol, 1-tetradecene, and tetrapropylene glycol in the amounts shown in Table 2 to prepare metalworking oils.

[0336] Next, a test of processing aluminum fins was performed on the obtained processing oil. That is, as the lubricity, the coefficient of friction was evaluated. Odor and dryness were also evaluated.

[0337] The results are all described in Table 4.

[0338] The test methods of the test items are as follows.

[0339] Lubricity test method:

[0340] Material Aluminum JIS A1050 material

[0341] The coefficient of friction was evaluated using the Bauden test.

[0342] Load 250g, sliding speed 100mm / s

[0343] Determination method of odor:

[0344] The odor was judged in the state which heated the sample oil to 40 degreeC.
