Definitions
- the present invention relates to a composition for lubricating and / or descaling in the hot processing of metals, the composition consisting of a mixture of solids.
- the present invention also encompasses the use of the composition according to the invention in the hot processing of metals, the composition being applied to the metal in powder form or granulate form.
- Descaling agents are typically mixtures of solids that are pneumatically introduced into the interior of the hollow block that has been created immediately after the piercing process. When it comes into contact with the steel surface, which has a temperature of approx. 900 - 1250 ° C, the solid mixture melts and reacts with the hard scale, which immediately forms through a reaction with the oxygen in the air and primarily consists of layers of FeO (wüstite), Fe3Ü4 (magnetite) and Fe2Ü3 ( Hematite).
- unconverted scale can damage the inner surface of the pipe and thereby reduce the quality of the pipe produced.
- scale can damage the mandrel Cause rods, which has a considerable effect on the economy of the production process, since the costs for tools are comparatively high.
- High-temperature lubricants are used in the manufacture of seamless steel tubes by means of rolling processes. Many conventional high temperature lubricants are based on a mixture of borax and sulfates. Other high temperature lubricants known from the prior art are based on condensed phosphates or borates.
- Phosphate-based formulations are relatively sensitive and complex in practical use and do not forgive mistakes.
- particular attention must be paid to metering and adherence to relatively narrow limits when setting the systems in order to achieve an even distribution of the amount of lubricant over the entire inner surface of the hollow block.
- Local overdosing in particular in the hollow block increases the risk of internal defects when rolling out the steel pipes.
- Borax-based formulations have proven to be very reliable and relatively easy to use (especially with regard to overdosing).
- the main disadvantages of formulations based on borax are the lack of additional lubrication compared to phosphate-based formulations and the tendency to clump due to water absorption at increased air humidity.
- high-temperature lubricants are also known which are based on kondensier th phosphates and have a proportion of borates. Above all, the proportion of water-soluble borates is usually kept deliberately low due to the existing ecological and toxicological risks (e.g. DE 102013 102 897).
- the object of the present invention was to provide a composition for the lubrication and / or descaling in the hot processing of metals that does not have the disadvantages, as can be observed with the conventional high-temperature lubricants described above, such as local overdosing or clumping.
- composition for lubricating and / or descaling in the hot processing of metals consisting of a solid mixture that contains the following components:
- boron compound selected from boron-silicate glass, boric acid, boric acid salt or a mixture thereof,
- the composition according to the invention is very suitable as an agent for descaling and as a lubricant for the hot processing of metals. This is due in particular to the balanced ratio of components (a) condensed alkali metal phosphate and (b) boron compound and to the fact that the sum of components (a) and (b) makes up at least 50% by weight of the mixture. In certain embodiments, the sum of components (a) and (b) even makes up at least 60% by weight of the mixture.
- the composition proposed here is able to chemically convert scale very effectively.
- there is also a pickling reaction on the steel surface which leads to a higher quality.
- the composition according to the invention has proven to be very reliable and relatively easy to use (especially with regard to overdosing).
- the proportion of condensed alkali metal phosphate according to the invention ensures that a high-temperature stable hydrodynamic lubricating film is formed which demonstrably leads to a reduction in the rolling force. It has also been shown that this effectively reduces the risk of secondary scaling.
- the lubricating effect imparted by the proportion of condensed alkali metal phosphate protects the tool (mandrel bar) from wear and thus increases its service life.
- alkali metal or alkaline earth metal sulfate and fatty acid, fatty acid salt or a mixture thereof have the effect that the composition according to the present
- the invention also does not suffer from the disadvantages of the conventional high-temperature lubricants described above, such as, for example, local overdosing or clumping.
- the composition according to the present invention can be dosed via pneumatic injection systems with relatively wide tolerance ranges, within which a uniform distribution of the amount of lubricant is achieved over the entire inner surface of the hollow block. The risk of local overdosing in the hollow block is thus reduced.
- the composition according to the present invention does not tend to clump even with increased air humidity.
- the condensed alkali metal phosphates (a) used according to the invention can be polyphosphates, pyrophosphates, metaphosphates or mixtures thereof.
- the condensed alkali metal phosphate (a) is selected from condensed sodium or potassium phosphates or mixtures thereof.
- the condensed alkali metal phosphate (a) is disodium pyrophosphate [Na 2 H 2 P 2 0y], trisodium pyrophosphate [Na 3 HP 2 0y], tetrasodium pyrophosphate [Na 4 P 2 0y], sodium tripolyphosphate [NasPsOio], sodium trimetaphosphate [(NaP03) 3], sodium polyphosphate [(NaP03) n ], dipotassium pyrophosphate [K2H2P2O7], tripotassium pyrophosphate [K3HP2O7], tetrapotassium pyrophosphate [K4P2O7], potassium tripolyphosphate [K5P3O3), potassium tripolyphosphate [K5P3O3], potassium polyphosphate [K5P3O3], potassium polyphosphate [K5P3O3], potassium polyphosphate [K5P3O3], potassium polyphosphate [K5P3O
- the proportion of condensed alkali metal phosphate (a) is 20 to 60% by weight of the mixture. In certain embodiments of the invention, the proportion of condensed alkali metal phosphate (a) is 30 to 50% by weight of the mixture. In specific embodiments of the invention, the proportion of condensed alkali metal phosphate (a) is 35 to 45% by weight of the mixture.
- the boron compound (b) used according to the invention can be boron-silicate glass, boric acid, boric acid salt or a mixture thereof.
- the boron compound (b) is selected from boric acid [H3BO3], sodium borates, boric anhydride [B2O3], borosilicate glass and mixtures thereof.
- the boron compound (b) used according to the invention has a proportion of sodium borate or consists of it, the sodium borate being selected from sodium tetraborate and its hydrate stages [Na2B4Ü7 x H2O], in particular anhydrous sodium tetraborate [Na2ß407], sodium tetraborate pentahydrate [Na2ß4075H 2 0], sodium umtetraborate decahydrate [Na2B4Ü7 IOH2O], sodium metaborate [NaB0 2 4H 2 0] and mixtures thereof.
- sodium borate being selected from sodium tetraborate and its hydrate stages [Na2B4Ü7 x H2O], in particular anhydrous sodium tetraborate [Na2ß407], sodium tetraborate pentahydrate [Na2ß4075H 2 0], sodium umtetraborate decahydrate [Na2B4Ü7 IOH2O], sodium metaborate [Na
- the proportion of boron compound (b) is 10 to 40% by weight of the mixture. In certain embodiments of the invention, the proportion of boron compound (b) is 15 to 35% by weight of the mixture. In specific embodiments of the invention, the proportion of boron compound (b) is 20 to 30% by weight of the mixture.
- the solid mixture of the present invention preferably contains only a small proportion of soluble borates or boric acid, since these pose a high risk potential for humans and the environment.
- the boron compound according to component b) consists preferably of at least 70% by weight, at least 80% by weight or even at least 90% by weight of borosilicate glass. Boron-silicate glass is advantageous from this point of view as the borate content in the ground boron-silicate glass is poorly soluble in water, so that the high requirements of the applicable waste water guidelines are easier to meet.
- the sulfates used according to the invention in cooperation with the boron compound used according to the invention, form a particularly good pickling agent and thus make a significant contribution to improving the quality of the steel surface.
- the sulfates (c) used according to the invention can be alkali metal or alkaline earth metal sulfates or mixtures thereof.
- Alkali sulphates have a comparatively low melting point and therefore pass relatively quickly into the liquid phase when used, which is desirable in most cases.
- Alkaline earth sulfates have a higher melting point.
- the alkali metal or alkaline earth metal sulfate (c) is an alkali metal sulfate that is selected from sodium or potassium sulfate, potassium hydrogen sulfate or mixtures thereof.
- the proportion of alkali or alkaline earth sulfate (c) is 10 to 30% by weight of the mixture.
