Definitions
- the present invention relates to a lubricant for lubricating two surface-contacting heated metal objects, which perform a relative movement to each other, wherein the lubricant has a content of graphite and a content of at least one sheet silicate. Moreover, this invention relates to the use of such a lubricant in the hot deformation of metals and in particular in the manufacture of seamless pipes.
- a solid steel block is heated to a specific forming temperature and rolled out into a short, thick-walled hollow body, the pipe core.
- This tube blank is inserted via a tool, the mandrel, and extended or forged over the mandrel without additional heat supply.
- lubricants for lubricating two heated metal objects in contact with each other in terms of area, such as, for example, a mandrel and a tube.
- Various lubricant compositions are known from the state of the art, which are basically suitable for lubricating two hot metal objects contacting each other in a planar manner.
- a large proportion of these lubricants contain graphite as an ingredient, which is also well-known as a lubricant for metal objects at ordinary ambient temperatures.
- a disadvantage of graphite-containing lubricants is that, in particular at high processing temperatures, carburization frequently takes place, the graphite occupying outer grid positions of the B-scale crystal (iron carbide formation), which can lead to partial embrittlement.
- the brittle material breaks at this point, and the part is unusable. The reject rate is increased, which is economically unsustainable.
- EP 0 745 661 discloses a graphite-containing lubricant which has a proportion of one or more clay minerals from the class of smectites. In addition, these lubricants either have a content of silica sol or potassium aluminosilicate. According to EP 0 745 661, such lubricants can largely overcome the disadvantage of the Aufkoh ⁇ ment of graphite-containing lubricants at relatively high operating temperatures.
- lubricants containing both graphite and alkali-containing phyllosilicate may have less carburization in metalworking, they often require improvement in the friction ratios between the metal surfaces in order to improve the durability of the tooling tools, e.g. the mandrel rods, extend.
- the object underlying this invention is therefore to provide a graphite-containing lubricant which has no carburization when lubricating two heated metal objects which contact one another in a planar manner and which move relative to one another, and the restraining forces occurring between the surfaces of the metal objects reduced in comparison to corresponding lubricants from the prior art, so as to extend the durability of the very expensive tools (eg mandrel bars).
- a lubricant of the type mentioned which is additionally da ⁇ characterized in that the lubricant, based on the solids content, at least 5 wt .-% alkali-free hydrous sheet silicate has.
- the group of alkali-free hydrous sheet silicates has the common feature that these phyllosilicate minerals are substantially free of alkali.
- the group of alkali-free wasserhal ⁇ term sheet silicates includes, inter alia, the minerals kaolinite, antigorite, halloysite, greenalite, pyrophyllite, talc, margarite, vermiculite, sudoite and chlorite.
- the mica or micaceous sheet silicates are among the three-layer silicates.
- the group of three-layer silicates includes e.g. the frequently used alkaline-containing smectites (inter alia montmorillonite), which are contained, inter alia, in the bentonites as main minerals.
- the lubricant contains at least 30% by weight of graphite, based on solids content.
- the graphite used can be of synthetic as well as natural origin.
- the graphite content of a lubricant according to the invention is in a range of 30-90% by weight, and more preferably the graphite content is 50-80% by weight, based on the solids content. It is astonishing that even with lubricants according to this invention with relatively high graphite content no carburization could be detected on the surface of the machined metal objects.
- the lubricant comprises at least 10% by weight of phyllosilicate based on solids content.
- the lubricant preferably comprises 10-50% by weight of phyllosilicate, and phyllosilicate fractions, based on the solids content, of 20-40% by weight are particularly preferred. It should be noted that in some embodiments the proviso only applies that the proportion of alkali-free hydrous sheet silicate in the Bacllsili ⁇ catgehalt of the lubricant is at least so high that the proportion of alkali-free hydrous sheet silicate, based on the solids content of the total lubricant, at least 5 wt. -% is.
- Vor ⁇ preferably comprises the lubricant, based on the solids content 10-90 wt .-% alkali-free hydrous sheet silicate, wherein the lubricant particularly preferably 20-60 wt .-% alkali-free hydrous sheet silicate comprises.
- alkali-free hydrous sheet silicates which have single-component single layers, for example kaolinite, antigorite and halloysite.
- Further preferred alkali-free hydrous sheet silicates selected from the group of non-hydrated alkali-free hydrous phyllosilicates.
- Kaolinite is white, soft and flaky in its purest form.
- the two-layered kaolinite layers are not hydrated and are unfolded.
- Particularly characteristic of kaolinite is the great tendency for intercalation of chemical substances between the individual kaolinite layers.
- the unfolded silicate layers are particularly stabilized.
- the hydrated aluminum ions act in principle as very large ions.
- Kaolinite is obtained either by slaking the clay kaolin or synthetically from polysilicic acid and aluminum hydroxide. Since kaolins consist predominantly of the mineral kaolinite (about 88%), kaolin is used instead of pure kaolinite in some embodiments, i. that the proportion of kaolinite, based on the solids content, is achieved by a correspondingly higher addition of kaolin. In other embodiments, both kaolinite and kaolin are used in appropriate amounts. The same applies to synthetically produced kaolinite, i. in that preferred lubricants according to the present invention are additionally characterized by comprising kaolin or synthetically produced kaolinite. The advantage of using the kaolin clay is the lower cost of the raw material.
- the lubricant according to the invention comprises both kaolin and synthetically produced kaolinite.
- Further embodiments of the invention are additionally characterized in that they comprise at least one thickener.
- the at least one thickener is a bentonite, among which particularly smectites are preferred among the bentonites, and montmorillonite is particularly preferred among the smectites.
- a particularly preferred specific embodiment of the present invention comprises, based on the solids content, at least 50-79% by weight of graphite, 20-40% by weight of kaolinite and 1-10% by weight of thickener.
- preferred embodiments of the invention comprise at least one alkali metal thophosphate, particular preference being given to those alkali metal phosphates which are selected from trisodium, tripotassium or trilithium orthophosphate.
- alkali orthophosphates is well known in the art, and for the purposes of this invention, preferably comprises 0.5-15% by weight, based on the solids content of the lubricant. Particularly preferred is the - -
- Alkali orthophosphate content in the range of 1-10% by weight, based on the solids content of the lubricant, and more preferably in the range of 1-7.5% by weight.
- the lubricants according to the invention can be used wherever, at high temperatures, two metal objects in contact with one another flatly make a relative movement relative to one another. These include e.g. also roller cages for plain bearings, where elevated temperatures can occur.
- the lubricants according to the invention are preferably used in contact with one another on flat metal objects, one of which is a tool and another is a workpiece.
- the lubricant according to the invention is in the form of an aqueous solution or dispersion or suspension.
- the solids content of such a solution or dispersion / suspension is preferably 25-35% by weight.
- aqueous preparation of a lubricant according to the invention can, for example, be applied to the tool (for example a mandrel bar), the lubricant forming a fine separating and lubricant film after evaporation of the water.
- the inventive concept is suitable for the lubrication of any metal objects, but is preferably used in the hot deformation of metals, preferably at working temperatures of about 700-1300 9 C.
- Under metal pipes are understood here, for example, tubes made of non-ferrous metals, aluminum or the like.
- the graphite used in this example was a natural graphite having a purity of> 98% and an average particle size of 6 ⁇ m.
- the kaolinite used was obtained by kaolin slurry (kaolin EGS 80, Erbslöh).
- the thickener used was a modified bentonite (Optigel WM, Süd-Chemie).
- the 30% aqueous suspension of the above composition was sprayed on the about 80 9 C hot mandrels of a MPM (Multiple Purpose MiII). After evaporation of the carrier liquid, the tubes were rolled. The case determined restraining forces were 85 to at a 1150 0 C block temperature. The durability of the spikes was 2000 pipes.
