    Schmierstoff für die Verwendung bei der spanlosen Verformung von Stahl bei hohen Temperaturen und insbesondere bei der Herstellung von nahtlosen Rohren in sogenannten Multiple pipe mills, wobei der Schmierstoff wasserfest auf dem Werkzeug haften muss. Erreicht wird dies durch einen Schmierstoff, enthaltend neben einem Festschmierstoff und einem Verdickungsmittel einen Binder aus der Reihe der carboxylierten Styrol-Butadienlatices.

    专利说明:

    Binding refers to a lubricant intended for use in the hot working of metals by pressure.
    The purpose of the invention is to increase the water resistance and thickness of the lubricating film of the material.
    For preparing lubricant material, graphite and / or molybdenum disulfide is used as a solid lubricant filler, a compound selected from groups including polysaccharides, polyacrylic acid, polynvinylprondolndon, clay, and as a bond - clrboxed styrene-diene latex with 60-90 wt.X styrene content in it.
    Among solid lubricants, graphite gives particularly good results and it is preferable to use graphite with high purity, for example over 96Ј and with an average grain size of no more than 300 microns. The best results are achieved using graphite 99.5%. purity with an average grain size JOO microns. The lubricant is a 40-60% aqueous dispersion. The viscosity of the dispersion is preferably 500-15,000 cP at 10-30 ° C. The lubricant is prepared by simply mixing the components in water. The composition of the lubricant is given in table.1.

    ABOUT
    For comparative tests, a COMPOSITION of a known lubricant (composition 12) was prepared, which is an OOH aqueous lubricant dispersion, comprising the following components, in wt.%:
    Graphite54
    Complete phosphate 11
    Buru5
    Sodium silicate 10
    Polyethylene 1B
    Alkyl cellulose 2
    Water dispersion can be applied to the instrument with a temperature of 80-350PC and more. In this case, in contact with the hot surface, the aqueous dispersion carrier evaporates and a lubricant film of uniform thickness is formed. The lubricant film is homogeneous and, to a large extent, waterproof, as it does not wash off with water, and the film does not swell. The lubricant is suitable for disassembling a tool, for example a mandrel, a mandrel bar or a matrix, when used in machining workpieces, for example, liners or Tpy6v, in particular, for thermomechanical treatment of steel and rolling sleeves to produce seamless pipes on tube rolling mills with 6-8 stands , if necessary, on peeler stanlh, in presses for pressing rods or forging presses,
    Smolzochenn materials of compositions & 1–12 igpitals on pipe rolling stanlhs with 6–8 cages. During the test, the coheenon properties of the lubricant (adhesion of the lubricant to the metal surface), water resistance, which was determined by the amount (%) of the thin film insoluble about water, the trussiness of the film, determined by the Iar Pan method (according to Seekens) at 150-260 ° C, plank thickness and viscosity
    water d: lubricant sperm. The test results are shown in table 2.
    As can be seen from the data of Table 2, the resistance of the proposed lubricant is 3 times higher than the known one, and the thickness of the lubricating film on the metal surface increases from 15 to 40-60 microns.
