专利说明:
tal, i.e., - (HjO... Sodium metaphosphate, potassium metaphosphate, monosodium phosphate (anhydrous or containing), sodium tetraborate ditetrahydrate, potassium tetraborate tetrahydrate as well as ortho, meta, pyrophosphates and borates can also be used. The material is effective in hot drawing of alloys that are difficult to draw, for example, an alloy containing, in particular, 4, 2% copper and about 1.2% lead magnesium and manganese. These alloys are usually subjected to drawing at low speed to avoid surface tregDin., alloy Drawn using the proposed lubricant, there are no cracks on the surface, voids in the center, usually caused by differences in the speed of drawing in the core and the peripheral part, and do not have a coarse-grained peripheral zone as a result of recrystallization in a heated state — as it passes through the drawing wire. The ability of the proposed lubricant to be dissolved in water, pure or weakly acidic, allows the lubricant to be removed from the surface of the products by simple washing. Example 1 A vitreous material is prepared as a drawing lubricant consisting of 270 g of sodium dihydrate primary phosphate dihydrate and 30 g of potassium tetraborate 30 g of water. Both products are thoroughly mixed, gradually heated until complete dehydration, then brought to a vitreous melting state. After cooling, the vitreous material is crushed so as to completely pass through a sieve with a mesh size of 63 microns,;. Then 200 g of this crushed glass material is pressed into a disk with a diameter of 84 mm and a thickness of 15 mm. As a result, a lubricant of the following composition is obtained, weight,%: 62.1 6.9 27.1 3.9 Lubricants are usually made of phosphates (ortho -, meta or pyrophosphates) and borates and, if necessary, with the addition of boric anhydride. Example 2. Composition of lubricant, weight,%: Anhydrous monosodium NaHiPO phosphate p Boric anhydride, 7 Anhydrous disodium phosphate, 9 After melting, the lubricant has the following composition, weight,%: Р2.05 64.9 3.1 .32.0 Example 3, Composition lubricants. This lubricant provides a drag speed of 300 m / min. Example 4. Lubricant composition, weight,%: In this composition, the amount below the proposed limit, which causes the formation of crystals and the profiles come out with severe damage (this composition does not preserve the vitreous state and recrystallization occurs). It is not suitable for practicing the invention. Thus, the proposed lubricant formulations (examples 1-3) have the required qualities to provide high speed drawing, i.e. viscosity P, 400-650 s, solubility in water and the absence of crystallization. When tested, the lubricant disc is brought into contact with. drawing point in a stamp of a high-speed drawing press, preheated approximately to. Then, a blank of a certain alloy with a diameter of 83 mm is introduced. 100 mm long, pre-heated with dO approximately and covered over the entire surface with the same vitreous material, and immediately proceed to the drawing. An aluminum-based metal containing 4.2% Cu and 1.2% Pb is tested. The feed speed of the compacting part of the press is adjusted so that the profile with a diameter of 12 mm at the corresponding speed leaves. The test results are presented in the table. Composition of lubricant according to drawing speed, m / min. Example. Low speed, damaged profiles. Known 14. Known lubricant has the following composition, wt.%: PjiOy46,2 AljiO, 5.0 ,eight As can be seen from the table, the proposed lubricant compositions for drawing alloys based on light metals provide fairly high drawing speeds of up to 382 m / min. The resulting bars of the wire: locks do not have any external or internal objects. The coefficient of stretching is 50.
