Definitions

  • the present invention relates to a composition for protection against scale and as a lubricant for the hot processing of metals.
  • thermoforming metals especially steel
  • in a temperature range of 500-1300 ° C such as rolling or drop forging
  • it comes on the heated metal surface of the ambient air to the formation of scale which can be designed differently strong depending on the transfer time to the next process step
  • a solid material is pierced and a hollow block is formed, which is then elongated in subsequent rolling steps.
  • the danger of scale formation on the heated metal surface of the hollow block during the transfer to the Elongierrind is particularly high.
  • this scale attack can lead to internal defects of the seamless pipe. For this reason, the resulting scale is blown out, for example, with compressed air or inert gas.
  • lubricant or mordant or scale solvent on the inner surface of the hollow blocks.
  • examples of such agents include graphite, boron nitride, molybdenum sulfide, silicates, sodium salts, alkali sulfates, saponified fatty acids or alkaline earth phosphates and mixtures thereof. Frequently alkali borates with different water of crystallization or boric acid are used.
  • the forging process in particular of large and heavy parts, such.
  • a contouring, wheel rolling and finish forging is at> 1200 ° C preheater, upset before the Hauptumform suitsen, cylindrical metal block in a preforming press, ie roughly preformed into a disk shape. Due to the process-related relatively long residence times of the heated parts it comes to the surface strong secondary delays that adversely affect the forming as well as the quality of the parts surfaces. If such a metal part before heating or the first forming step with lubricating, pickling, u. Coated with scale solvents of the aforementioned type, these negative influences reduce significantly.
  • a lubricant for the hot processing of metals which contains a high proportion of water-soluble boron compounds, is for example in the WO 2008/000700 described.
  • the object of the present invention was therefore to provide a composition acting as protection against scale and as a lubricant for the hot processing of metals, in which the risk potential based on the boron compounds previously used as constituents is reduced compared with the prior art, the good trickle and has flow behavior and good properties in terms of scale dissolution on heated metal surfaces and lubrication and applied in powder form allows a good coverage of the metal surface and requires little or no graphite.
  • lubricant according to the invention may contain further constituents, as long as they do not significantly adversely affect the desired advantageous properties.
  • the composition according to the invention is very well suited as an agent for protecting against scale and as a lubricant for the hot processing of metals, although they have no or, compared to known borate-based lubricants, only a very small optional amount of borates or boric acid having.
  • the proportion of easily water-soluble borates, which entail a high hazard potential for humans and the environment, is considerably reduced or at best even completely excluded in the case of the composition according to the invention compared with known agents.
  • the composition according to the invention forms the desired melt faster than in the case of known lubricants and ensures good lubrication and good protection against scale. This is achieved by the inventive combination of ingredients, it was surprising that the requirements for the lubrication and protection against scale of the composition despite the proportion of ground boron-silicate glass and the low proportion of boric acid or borate could be achieved.
  • a particular advantage of the composition according to the invention consists in a significantly lower solubility of the borate portion compared to the prior art with comparable or even better effectiveness and functionality.
  • This reduced solubility of the borate portion is achieved by a low or no amount of boric acid and / or boric acid salt according to component (e) and may be further modified by varying the ratio of the proportion of fatty acid and / or fatty acid salt of component (b) to boric acid and / or boric acid salt according to component (e).
  • the borate content in the milled boron-silicate glass is extremely poorly water-soluble.
  • the composition has a hemisphere point> 400 ° C.
  • the hemisphere point is reached when a specimen in the examination of the ash melting behavior in the heating microscope has approximately the shape of a hemisphere.
  • a hemisphere point> 400 ° C. of the composition according to the invention has the advantage that the melting point of the composition is not reached too early and a viscosity suitable for the application is maintained. If the hemisphere point of the composition is below 400 ° C., the viscosity of the melt in the range of use of 600-1300 ° C. is too low and a sufficient melt film is not obtained.
  • Secondary and / or tertiary calcium phosphate compounds have surprisingly proven to be particularly suitable flow aids in a composition of the type according to the invention for the hot processing of metals.
  • Monocalcium phosphate is unsuitable because it leads to clumping when humid.
  • the calcium phosphate compound (a) is selected from hydroxy dia- betite [Ca 5 (PO 4 ) 3 OH] and tricalcium phosphate [Ca 3 (PO 4 ) 2 ], with hydroxy dia- pate being particularly preferred.
  • the calcium phosphate compound (a) is contained in the composition in an amount of 1 to 5% by weight.
  • the composition of the present invention further contains a fatty acid, a fatty acid salt or a mixture thereof in combination with the other ingredients. It has surprisingly been found that by using a fatty acid or a fatty acid salt, the agglomeration of the fine-grained powder can be significantly reduced and the storage stability can be improved. Without the applicant's being bound by theory, it is believed that the fatty acid or fatty acid salt attaches to the granules of one or more other constituents of the mixture and thus prevents or reduces clumping of the granules, preventing moisture from the granules and thereby improves the storage stability and the flow or flow behavior of the lubricant. In addition, it is believed that the fatty acid or fatty acid salt improves lubrication due to decomposition in the range of use of 600 - 1300 ° C and formation of a gas cushion.
  • the fatty acid or fatty acid salt (b) is selected from saturated and unsaturated fatty acids containing 6 to 26 carbon atoms or their salts, preferably caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, margaric acid, stearic acid, Arachidic acid, behenic acid, lignoceric acid, cerotic acid, palmitoleic acid, oleic acid, elaidic acid, vaccenic acid, icosenoic acid, erucic acid, nervonic acid, linoleic acid, linolenic acid, arachidonic acid, timnodonic acid, clupanodonic acid or salts thereof, provided that the fatty acid or the fatty acid salt is> 30 ° C is present as a solid.
  • the fatty acid or the fatty acid salt is particularly preferably stearic acid or salts thereof.
  • the fatty acid or fatty acid salt (b) is in an amount of 1 to 15 wt .-%, preferably from 1 to 10 wt .-%, particularly preferably from 3 to 7 wt .-% in of the composition.
  • the milled boron-silicate glass (c) has a grain size with an average particle size D50 of ⁇ 300 ⁇ m.
  • the milled boron-silicate glass improves the uniform distribution of the composition on the hot metal surface and reduces scale formation. At the high temperatures of metal processing, the composition forms a melt, the boron-silicate glass improving the rapid formation of the melt and ensuring it over a broader temperature range than known lubricants. If the average particle size of the milled boron-silicate glass in the composition is too large, the formation of the required melt after application of the composition may disadvantageously take too long.
  • the boron-silicate glass (c) in an amount of 3 to 80 wt .-%, particularly preferably from 5 to 15 wt .-% in the mixture.
  • the condensed alkali metal phosphates (d) are condensed sodium or potassium phosphates or mixtures thereof, preferably polyphosphates and / or pyrophosphates and / or metaphosphates or mixtures thereof, more preferably disodium pyrophosphate [Na 2 H 2 P 2 O 7 ] trisodium pyrophosphate [Na 3 HP 2 O 7 ], tetrasodium pyrophosphate [Na 4 P 2 O 7 ], sodium tripolyphosphate [Na 5 P 3 C 10 ], sodium trimetaphosphate [(NaPO 3 ) 3 ], sodium polyphosphate [(NaPO 3 ) n ] , Dipotassium pyrophosphate [K 2 H 2 P 2 O 7 ], tripotassium pyrophosphate [K 3 HP 2 O 7 ], tetrapotassium pyrophosphate [K 4 P 2 O 7 ], potassium tripolyphosphate [K 5
  • the condensed alkali metal phosphates (d) in an amount of 40 to 80 wt .-%, preferably from 40 to 75 wt .-% in the mixture.
  • the constituent (e) of the composition according to the invention is boric acid [H 3 BO 3 ], borax [Na 2 B 4 O 5 (OH) 4 .8H 2 O or Na 2 B 4 O 7 .10H 2 O], sodium borates such as Na 2 B 4 O 7 .5H 2 O, Na 2 B 4 O 7 (anhydrous), sodium metaborate [NaBO 2 .4H 2 O] boric anhydride [B 2 O 3 ] and Mixtures thereof selected.
  • the mixture has an average particle size D50 of ⁇ 250 ⁇ m, preferably of ⁇ 200 ⁇ m. Due to the small average particle sizes of the constituents of the mixture according to the invention, the flow and flow behavior of the composition according to the invention compared to known lubricants is significantly improved, facilitates the spraying on surfaces as a powder and ensures better and more uniform layer formation or occupancy on the metal surface. At the same time, the combination of the constituents of the mixture according to the invention prevents or reduces clumping which has regularly occurred in the case of lubricants according to the prior art with small particle sizes and has led to considerable disadvantages.
  • the mixture has an average particle size D50 of ⁇ 3 ⁇ m, preferably ⁇ 10 ⁇ m, particularly preferably ⁇ 15 ⁇ m. It has been found that too small average particle sizes can only be produced with great difficulty and at relatively high costs on the one hand and on the other hand they also increase the tendency to clumping again. An average particle size in the range of 20 to 50 microns has therefore proved to be optimal.
  • the invention also includes the use of the inventive composition for the protection against scale and as a lubricant in the hot processing of metals, wherein the composition is applied in powder form to the metal, preferably inflated.
  • the composition of the invention is characterized by more stable storage properties, faster melting in contact with the hot workpiece due to the larger surface, better inflatability and more uniform distribution on the surface of the workpiece as well as safer and more economical Dosage off.
  • the dry, powdered use of the composition of the invention has the advantage that no unwanted cooling of the workpiece is carried by the liquid and also the additional step of preparing the application suspension is unnecessary ,
  • the average particle size of the mixture or constituents of the composition according to the invention is determined by means of a Cilas Model 715/920 laser granulometer from Cilas. Inc. Approximately 80 mg of sample is suspended in 2-propanol and the measurement is made one minute after preparation of the suspension according to the manufacturer's instructions.
