Definitions
- Lubricants used in the hot forming of metals have long been known.
- Such lubricants consist for example of mixtures of graphite and mineral oil. Such mixtures decompose at the usual application temperatures of 1100 to 1300 ° C and result in a strong environmental impact.
- Lubricants that are used in the manufacture of seamless tubes for the lubrication of the so-called mandrel bars must meet special requirements and therefore consist of graphite and mixtures of substances that provide these special properties.
- DE-B-2 350 716 describes a high-temperature lubricant made from 10 to 90% graphite, 2 to 60% alkylene polymer or copolymer, 0.2 to 8% suspension aid and 2 to 40% film stabilizer.
- EP-A-0 554 822 describes a lubricant which, in addition to graphite, contains one or more clay minerals from the smectite class, polysaccharide and a nonionic surfactant.
- the previously known lubricants contain, in addition to graphite, organic and thus decomposable substances and / or additives which heavily contaminate the wastewater that arises later, for example through sludge formation, and thus represent a great environmental burden.
- the object on which the invention is based was therefore to obtain a lubricant which, in particular, can be used as a mandrel lubricant, which, in addition to graphite, contains essentially no organic substances which can be carbonized as far as possible and has as little environmental damage as possible with regard to the wastewater pollution.
- this object is achieved with a lubricant with a content of 75 to 90% by weight of graphite, which is characterized in that it contains 1 to 10% by weight of phosphates.
- lubricants according to the invention over those according to the prior art, in particular over dome lubricants, can be seen in the fact that they need not contain any organic substances and preferably do not contain any organic substances at all, so that the graphite is the only decomposable component. They therefore preferably contain only inorganic substances.
- Graphite which has the main lubricating effect of such lubricants, consists of pure carbon, which burns at high application temperatures in an oxygen-containing environment, producing carbon dioxide, which creates a gas cushion on which the first
- REPLACEMENT BLART (RULE 26) Line based on the separation of tube and mandrel bar.
- the other ingredients of the lubricant have the task of producing a uniform lubricating film, causing the lubricating film to dry quickly and avoiding damage to the mandrel rod or the inner surface of the pipe.
- these objects are primarily achieved by the phosphates, which form a low-viscosity, reactive melt at the high application temperatures, which is able to dissolve scale and similar impurities and thus to avoid their harmful effect.
- the lubricants according to the invention preferably contain 85 to 90% by weight of graphite and advantageously 3 to 5% by weight of phosphates.
- a phosphate mixture of tetrasodium diphosphate, primary zinc orthophosphate, primary manganese orthophosphate, disodium dihydrogen diphosphate and potassium polyphosphate as phosphates in the lubricant according to the invention.
- This phosphate mixture advantageously contains 25 to 50, preferably 33 to 43% by weight of tetrasodium diphosphate, 1 to 20, preferably 3 to 11% by weight of primary zinc orthophosphate, 0.5 to 20, preferably 1 to 10% by weight of primary manganese orthophosphate, 2 to 25 , preferably 5 to 15% by weight disodium dihydrogen diphosphate and 8 to 35, preferably 15 to 25% by weight potassium polyphosphate.
- a phosphate mixture fine-tuned for this purpose contains about 38% by weight of tetrasodium diphosphate, about 7% by weight of primary zinc orthophosphate, about 5% by weight of primary manganese orthophosphate, about 10% by weight of disodium dihydrogen diphosphate and about 20% by weight of potassium polyphosphate.
- the phosphate mixture added to the lubricant as phosphates additionally contains 5 to 25, preferably 10 to 20% by weight of boric acid and / or 0.5 to 15, preferably 1 to 10% by weight of hydroxyapatite.
- the finely tuned phosphate mixture listed above appropriately contains about 15% by weight of boric acid and about 5% by weight of hydroxyapatite.
- the lubricant according to the invention advantageously also contains 1 to 4, preferably 2 to 2.5% by weight of alkali silicate, in particular sodium disilicate , and / or 1 to 10, preferably 4 to 6% by weight of bentonite, preferably commercial bentonite 34 with 6 m 2 / g BET surface area, and / or 0.5 to 1, preferably 0.7 to 0.9% by weight.
- % Silicophosphate which enhance the effect of the phosphate mixture described above.
- the latter percentages relate to the total weight of the solids content of the lubricant according to the invention, while the percentages of the phosphate Mixtures including those of boric acid and hydroxyapatite refer to the total solids weight of the phosphate mixture alone.
- As sodium silicate one with a ratio of SiO 2 : Na ⁇ -O of 2 is expediently used.
- the silicophosphate used advantageously contains about 22% SiO 2 and about 54% P 2 0 5 .
- the mandrel lubricants according to the invention are preferably used as aqueous suspensions with a solids content of 20 to 40% by weight, preferably 25 to 35% by weight.
- the lubricant is applied in the usual way by spraying the suspension onto the mandrel bar after it has left the cooling bath and is transported back to the rolling process.
- the lubricants according to the invention can advantageously also contain customary solid lubricants, such as calcium fluoride, cryolite, antimony trioxide, molybdenum sulfide, zinc pyrophosphate, boron nitride or iron III pyrophosphate.
- customary solid lubricants such as calcium fluoride, cryolite, antimony trioxide, molybdenum sulfide, zinc pyrophosphate, boron nitride or iron III pyrophosphate.
- a lubricant according to the invention was prepared in the form of a 30% aqueous slurry, the solids content of which had the following composition: 85 parts by weight of natural graphite with 95% purity in the form of carbon
- the mandrel bars in circulation were sprayed with the above-mentioned lubricant on an MPM line for the production of seamless steel tubes. After the water content had evaporated, the layer weight of the dry lubricant film was 60 g / m 2 of the surface of the mandrel bar.
- a lubricant according to the invention was produced in the form of a 15% by weight aqueous slurry, the solids content of which consisted of the following components:
- the pilgrim mandrels were sprayed with an aqueous suspension of the above-mentioned lubricant.
- the layer weight on the mandrel bar was 20 g / m 3 before the forming process started.
- the mandrel bar was smooth and free of scale particles.
- the inner tube surface was also smooth.
- the internal roughness of the pipes had decreased significantly.
- the mean value was 10 ⁇ m.
- the surface of the mandrel bar was tainted with scale particles when using a known lubricant. These particles had to be ground by hand after twelve forming processes, which represents a considerable delay in production and is to be regarded as uneconomical.
- the mean value of the internal roughness of the pipes was 53 ⁇ m.
