Abstract

The present invention relates to a water resistant lubricant used for the thermoplastic processing of steel, which is used for the processing of rolling and forging type drawing production, etc. in the state of high temperature, and is especially suitable for a rolled seamless steel pipe with a core rod. The lubricant has favorable water resistant performance under the working environments that the water resistant lubricant is flushed by cooling water and is soaked in a cooling water tank for a long time. A solid lubrication material is added to the lubricant, and additionally, organic adhesive and an organic additive having favorable bonding performance during different temperature stages are also added to the lubricant. The granules of the solid lubrication material can be firmly conglutinated on a core rod by the added matter in the film forming stage of the lubricant. When high temperature plasticity processing is carried out, novel crack continuously occurs to achieve the functions of delaying graphite oxygen and enhancing lubrication performance.

Description

The thermoplasticity processing water tolerance lubricant of steel
The present invention relates to steel and add man-hour in thermoplasticity such as high temperature rolling, forging and drawing productions, the high temperature when being particularly useful for the cored bar rolling seamless steel pipe with lubricator.
At present, be applied to the lubricant for hot plastic working of steel, two classes are arranged.One class is an oil lubricant, (clear 61-19519) is contained according to Japanese documentation, this series lubricant agent is mixed by solid lubricants such as lubricating oil such as mineral oil, heavy oil, lubricating grease and Graphite Powder 99 or MoS2, and it is formulated to add additives such as alkali metal sulfates, Repone K, nitrilotriacetic sodium and water.Because the existence of oil, cause the unstable of heat, and because oil and resolvent thereof also pollute environment, most importantly the sliding lubrication prescription of this class does not have water tolerance, therefore, be unwell in the flushing that water coolant is arranged or be immersed in refrigerative Working environment in the water, another kind of is water base lubricant, records and narrates according to Japanese documentation (clear 57-185393) and Chinese patent literature (CN85103499A), this series lubricant agent is by solid lubricant (graphite, asphalt powder, MoS 2Or granular synthetic resin etc.), inorganic salts (phosphoric acid salt, silicate, borate etc.), organic polymer (polyvinyl acetate (PVA), polyacrylic ester, polyvinyl butyral acetal, alkylcellulose etc.) and water are formed suspension.This series lubricant agent has certain water resistance, can prevent washing away of roller-way water coolant and roll water coolant when rolling, soaks for a long time but can not bear in cooling trough.The garden this, when processing requirement after the mandrel surface deviate from behind wroughtsteel pipe spraying lubricant and drying, put into the tank cooling, as soaking through the long period and flowing water when washing away, this lubricant just manifests to come off easily and waits significantly deficiency.
The present invention is for a kind of water tolerance lubricant is provided, and after the lubricant film forming on the workpiece, the unlikely plug that comes off and be sprayed with lubricant of long-time immersion is when immersing cooling trough in tank, and lubricant is unlikely to come off.
Consisting of of water tolerance lubricant of the present invention:
1, (flaky graphite of particle diameter≤100 μ ml, purity>90%, weight percent is 10~40% to the certain granules degree.
2, DX-200 binding agent (organic class, vinyl-acrylate copolymer), weight percent is 5~40%.
3, the Ployethylene Wax binding agent, particle diameter requires≤100 μ m, and weight percent is 2~20%.
4, sodium polyacrylate or Xylo-Mucine binding agent, weight percent is 0.5~5%.
5, sodium methylene bis-naphthalene sulfonate additive, weight percent are 0.5~5%.
6, phenol or formaldehyde additive, weight percent is 0.1~2%.
7, water.Weight percent is 40~80%.
Because graphite in promote the oxidation more than 540 ℃, has destroyed the crystalline state of graphite, has reduced the lubricity of graphite.In order to delay graphite oxidation, utilize graphite that the ability of more intense adsorbed gas, the characteristics of reduction surface energy are arranged, that is to say the effect that produces slippage between the crystalline graphite layer is reduced.In order to give full play to the graphite good lubricating property, make it contain aerobic participation under agglomerative steam or certain situation usually.So, add some additive and make it under hot conditions, to reach this purpose.Among the present invention, the binding agent of use and additive all are organism, can give full play to the good lubrication performance of solid lubricants such as graphite under hot conditions.Be sprayed on when the water tolerance lubricant of forming by above-mentioned material on the workpiece such as plug, behind the drying and forming-film, can wrap in tightly every coccolith China ink particle around, and be bonded at firmly on the plug, unlikely by water dissolution, the temperature that adds man-hour along with thermoplasticity raises, these organism produce gas and water owing to new cracking constantly takes place, can play the effect that delays graphite oxidation, simultaneously, improve the lubricity of graphite.
Water tolerance lubricant of the present invention has suitable high temperature friction coefficient and good water-fast cohesiveness, and has improved motor load abnormal conditions in the operation of rolling and the quality that has improved rolled products.Water tolerance lubricant of the present invention encircles compression testing with the garden, and the frictional coefficient when being determined at high temperature is as following table.
Temperature ℃ 750 850 950 1050
Frictional coefficient 0.06 0.05 0.08 0.09
Embodiment: the water tolerance lubricant is used in high temperature thermoplasticity processing, carries out proportioning by following prescription:
1, purity is that 99% flakey hundred China inks are made solid lubricant, accounts for 15.9%;
2, sodium polyacrylate (or Xylo-Mucine) accounts for 0.5%;
3, Ployethylene Wax accounts for 3%,
4, DX-200 binding agent (vinyl-acrylate copolymer) accounts for 15%;
5, sodium methylene bis-naphthalene sulfonate accounts for 0.5%;
6, formaldehyde (or phenol) accounts for 0.1%;
7, water accounts for 65%.
Reach on the metal coupons of V8 when the suspension with this kind water tolerance lubricant is sprayed on 150 ℃ of temperature, surface smoothnesses, treat the complete drying film forming after, with 58.84 * 10 4During the high pressure water washing of Pa, this film is excellent.Be applied on the plug, 1050 ℃ right, then demonstrate the excellent high-temperature lubrication performance.
