AI Technical Summary

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 conducted as aluminum rolling oil.

[0315] The base oil of Table 1 was blended with butyl stearate, lauryl alcohol, and oleic acid as oiliness agents in the amounts shown in Table 2 to prepare metal working oil.

[0316] Next, the aluminum rolling process test, odor determination, and oil removal test were performed on the obtained processing oil.

[0317] The results are shown 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 rate of 35%, and the load required for processing was measured. If the required load is small, the workability becomes good, which is preferable.

[0320] Method for measuring odor:

[0321] The odor was determined in a state where the sample oil was heated to 40°C.

[0322] 10 judges made the evaluation. The scoring standards were: don't mind: 0 points, slightly odorous: 2 points, od...

Embodiment 2

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

[0335] The base oil of Table 1 was blended with butyl stearate, lauryl alcohol, 1-tetradecene, and tetrapropylene glycol in the amounts shown in Table 2 to prepare metal working oil.

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

[0337] The results are shown in Table 4.

[0338] The test method of the test item is as follows.

[0339] Lubricity test method:

[0340] Material aluminum JIS A1050 material

[0341] The Bauden test is used to evaluate the friction coefficient.

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

[0343] Method for measuring odor:

[0344] The odor was determined in a state where the sample oil was heated to 40°C.

[0345] 10 judges made the evaluation. The scoring standards were: don't mind: 0 points, slightly odorous: ...
