Problems solved by technology

This process will produce a lot of oil sludge in the production process, the surface quality of the ground steel ball is poor, there are many scratches, low precision, high vibration value, and the noise is very loud after being converted into a bearing
[0003] There are also fully synthetic lapping liquids, which have low lapping efficiency. Usually, it takes three days to produce a plate of steel balls. The amount of lapping liquid is large, the use cost is high, and the product quality is poor. Vibration value is also high

Embodiment 1

[0018] Take 70% of 46# mechanical oil by weight percentage and put it into a reaction kettle, then add 30% of refined oleic acid and stir to form a suspension evenly for later use.

[0019] Take 34% of 46# mechanical oil by weight percentage and put it into the reactor, add 31% of kerosene and stir, then heat up to 80°C, then add 10% of oleic acid, 6% of sodium petroleum sulfonate and 3% of sorbic acid The sugar-alcohol anhydride monooleate is fully stirred evenly, then sequentially add 8% polyoxyethylene castor oil, 4% triethanolamine oleate and 3% diethanolamine borate and stir thoroughly for 1 to 2 hours, and finally add 1% hydrogen Potassium oxide is stirred evenly to form a circulating fluid for later use.

Embodiment 2

[0021] Take 75% of 46# mechanical oil by weight percentage and put it into the reaction kettle, then add 25% of refined oleic acid and stir evenly to form a suspension for later use.

[0022] Take 40% of 46# mechanical oil by weight percentage and put it into the reactor, add 40% of kerosene and stir, then heat up to 80°C, then add 6% of oleic acid, 4% of sodium petroleum sulfonate and 1% of sorbic acid The sugar-alcohol anhydride monooleate is fully stirred evenly, then sequentially add 5% polyoxyethylene castor oil, 2% triethanolamine oleate and 1.5% diethanolamine borate and stir thoroughly for 1 to 2 hours, and finally add 0.5% hydrogen Potassium oxide is stirred evenly to form a circulating fluid for later use.

Embodiment 3

[0024] Take 73% of 46# mechanical oil by weight percentage and put it into the reaction kettle, then add 27% of refined oleic acid and stir to form a suspension evenly for later use.

[0025] Take 36% of 46# mechanical oil by weight percentage and put it into the reactor, add 36.5% of kerosene and stir, then heat up to 80°C, then add 8% of oleic acid, 5% of sodium petroleum sulfonate and 2% of sorbic acid The sugar-alcohol anhydride monooleate is fully stirred evenly, then sequentially add 6.5% polyoxyethylene castor oil, 3% triethanolamine oleate and 2.25% diethanolamine borate and stir well for 1 to 2 hours, and finally add 0.75% hydrogen Potassium oxide is stirred evenly to form a circulating fluid for later use.

Abstract

The invention discloses a method for preparing emulsion type lapping liquid for steel ball grinding, comprising a suspension and a circulating liquid, wherein the suspension is prepared from 70-75 percent of 46# machine oil and 25-30 percent of refined oleic acid; the circulating liquid is prepared from 34-40 percent of 46# machine oil, surplus coal oil, 6-10 percent of oleic acid, 4-6 percent of sodium petroleum sulfonate, 1-3 percent of sorbitan monooleate, 5-8 percent of polyoxyethylene castor oil, 2-4 percent of triethanolamine oleate, 1.5-3 percent of diethanolamine borate and 0.5-1 percent of potassium hydroxide. One part of chromium oxide is added to two parts of suspensions for mixing in a thin paste state, and 20-30ml chromium oxide suspension is needed by each 200-250kg steel ball and is brushed on the steel ball in one step; nine parts of tap water are added to one part of the circulating liquid for stirring and uniformly forming an emulsion type circulating liquid, and then the emulsion type circulating liquid is disposed in a water tank of a refining mill for circularly flushing the steel ball, and the grinding is finished by 20-24 hours. The autorotation of the steelball is fine in the refine grinding process, so the steel ball and plate grooves can be prevented from being corroded.

Description

technical field [0001] The invention belongs to the technical field of steel ball grinding liquid, and in particular relates to the preparation and use method of an emulsified lapping liquid for steel ball grinding. Background technique [0002] At present, most of my country's steel ball production industry adopts oil grinding production process. This process will produce a lot of sludge during the production process, the surface quality of the ground steel ball is poor, there are many scratches, low precision, high vibration value, and the noise is very loud after being converted into a bearing. [0003] There are also fully synthetic lapping liquids, which have low lapping efficiency. Usually, it takes three days to produce a plate of steel balls. The amount of lapping liquid is large, the use cost is high, and the product quality is poor. The vibration value is also high. Contents of the invention [0004] In order to solve the above problems, the present invention p...
