Abstract

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.

Description

Из бретение относитс  к смазочному материалу, предназначенному дл  применени  при гор чей обработке металлов давлением.The invention relates to a lubricant intended for use in hot metal forming.

Цель изобретени  - повышен е водостойкости и толщины смазочной пленки материала.The purpose of the invention is to increase the water resistance and thickness of the lubricating film of the material.

Дл  приготовлени  смазочного ма- териала используют в качестве твердого смазочного наполнител  графит и/или дисульфид молибдена, в качестве зл густнтел  - соединение, выбранное группы, включающей полисахариды, полиакриловую кислоту, полнвинилпнрро- лндон, глину, и в качестве св зуте- го - клрбокснлированный стиролбутл- диеновый латекс с содержанием в нем 60-90 мас.Х стирола.To prepare the lubricant, graphite and/or molybdenum disulfide are used as a solid lubricating filler, a compound selected from a group including polysaccharides, polyacrylic acid, polyvinylpyrrolidone, clay is used as a thickener, and crystalline styrene butyl diene latex containing 60-90% by weight of styrene is used as a binder.

Из числа твердых смазочных материалов графит дает особенно хорошие результаты и предпочтительно использование графита с высокой чистотой, например свыше 96Ј и со средним размером зерен не более 300 мкм. Наилучшие результаты достигаютс  применением графита 99,5%. чистоты со средним размером зерен JOO мкм. Смазочный материал представл ет собой 40-60%-ную водную дисперсию. В зкость дисперсии предпочтительно составл ет 500-15000 сП при 10-30°С. Смазочный материал готов т простым смешением компонентов в воде. Состав смазочного материала приведен в табл.1.Among solid lubricants, graphite gives particularly good results and it is preferable to use graphite with a high purity, for example over 96Ј and with an average grain size of no more than 300 µm. The best results are achieved by using graphite of 99.5% purity with an average grain size of JOO µm. The lubricant is a 40-60% aqueous dispersion. The viscosity of the dispersion is preferably 500-15000 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.

Дл  сравнительных испытаний был приготовлен СОСТЕВ известного смазочного материала (состав 12), который представл ет собой ЗОХ-ную водную дисперсию смазки, включающей следующие компоненты, мас.%:For comparative tests, a COMPOSITION of a known lubricant (composition 12) was prepared, which is a 300-degree aqueous dispersion of lubricant, including the following components, wt.%:

Буру5Buru5

Силикат натри  10Sodium silicate 10

Полиэтилен 1ВPolyethylene 1B

Алкилцеллюлоза 2Alkylcellulose 2

Водную дисперсию можно наносить на инструмент с температурой 80- 350РС и более. При этом в реэульта- те соприкосновени  с гор чей поверхностью водный носитель дисперсии испар етс  и образуетс  пленка смазочного материала равномерной тол- цины. Пленка смазочного материала  вл етс  гомогенной, а значительной степени водостойкой, так как не смываетс  водой, пленка при этом не набухает. Смазочный материал пригоден дл  смтки инструмента, например оправки, стержн  оправки или матрицы , при их применении при обработке заготовок, например, гильз или Tpy6v в частности при термомеханичес кой обработке стали и прокатке гильз дл  получени  бесшовных труб на трубопрокатных станах с 6-8 клет ми, при необходимости и на пилнгрнмопых станлх, в прессах дл  прессовани  прутков или ковочных прессах,The water dispersion can be applied to the tool with a temperature of 80-350С and more. In this case, as a result of contact with the hot surface, the water carrier of the dispersion evaporates and a film of lubricant of uniform thickness is formed. The film of lubricant is homogeneous, and to a large extent water-resistant, since it is not washed off by water, and the film does not swell. The lubricant is suitable for the lubrication of tools, such as mandrels, mandrel rods or matrices, when used in the processing of workpieces, such as sleeves or Tpy6v, in particular in the thermomechanical processing of steel and rolling of sleeves to produce seamless pipes on pipe rolling mills with 6-8 stands, if necessary also on sawmills, in presses for pressing rods or forging presses,

Смлзочнне материалы составов & 1-12 игпытынали на трубопрокатных станлх с 6-8 клет ми. В процессе испытани  оценивали когеэнонные свойства смазочного материала (силу сцеплени  смазочного материала с поверхностью металла), водостойкость, которую определ ли по количеству (%) смлзочной пленки нерастворимой о воде , тлордость пленки, определ емую методом иар панъ  (по Сиккенсу) при 150-260°С, толщину планки и в зкостьLubricating materials of compositions 1-12 were tested on tube rolling mills with 6-8 cells. During the test, the cohesive properties of the lubricant (the adhesive force of the lubricant to the metal surface), water resistance, which was determined by the amount (%) of the lubricant film insoluble in water, film thickness, determined by the IAP method (according to Sikkens) at 150-260 ° C, strip thickness and viscosity were evaluated.

водной д:сперсии смазочного материала . Результаты испытаний приведены в табл.2.aqueous dispersion of lubricant. The test results are given in Table 2.

Как видно из данных табл.2, водостойкость предлагаемого смазочного материала в 3 раза превышает известный , при этом толщина смазочной пленки на поверхности металла повы- шаетс  с 15 до 40-60 мкм.As can be seen from the data in Table 2, the water resistance of the proposed lubricant is 3 times higher than the known one, while the thickness of the lubricating film on the metal surface increases from 15 to 40-60 microns.
