Problems solved by technology

At present, hot rolling oil is mostly used in steel hot rolling lubricants. However, there are many problems in the use of traditional hot rolling oils, such as high oil consumption during the rolling process, bad production environment caused by smoke, residual pollution of cooling water, and slow rolling of steel after rolling. Poor corrosion and rust resistance

Embodiment 1

[0009] Embodiment 1 formula sees table 1:

[0010] Table 1

[0011] serial number component name weight (kg) 1 Aqueous molybdenum 60 2 Benzotriazole 90 3 Polyethylene glycol (PEG-4000) 750 4 Oleic acid 450 5 Triethanolamine 900 6 Isothiazolinone 150 7 Glycerol 600

[0012] Production Method:

[0013] Press each component weight formula of table 1: will 600kg Glycerol, 60kg Aqueous molybdenum, 900kg Triethanolamine, 450kg Oleic acid is added in sequence, and the rotation speed is 80-120 Heat and stir in the reaction kettle with rev / min, when the temperature reaches 80℃ while keeping warm and stirring continuously 60 minutes; then lower the temperature to 70℃， join in turn 750kg Polyethylene glycol (PEG-4000), 90kg Benzotriazole, 150kg Isothiazolinones, keep 70℃ and stir 90 Minutes, then stop heating, add water while stirring, wait until diluted to light brown, tha...

Embodiment 2

[0018] Production method is the same as embodiment 1, but raw material and percentage by weight are as table 3:

[0019] table 3

[0020] serial number component name weight (kg) 1 Aqueous molybdenum 30 2 Benzotriazole 75 3 Polyethylene glycol (PEG-4000) 780 4 Oleic acid 435 5 Triethanolamine 930 6 Isothiazolinone 120 7 Glycerol 630

[0021] The performance index of embodiment 2 is worse than embodiment 1, and embodiment 1 is a better formula.

[0022] Embodiment 1 of the present invention and embodiment 2 are in carrying out hot-rolled production process, be diluted to volume concentration according to actual situation to be 2%-6% rolling liquid, that is, a water-based rolling functional liquid that can be directly used in the hot rolling of strip steel and rail.

Abstract

The invention provides a hot-rolling functional liquid containing aqueous molybdenum and a preparation method of the hot-rolling functional liquid, belongs to the technical field of lubricant, and is characterized in that glycerine, the aqueous molybdenum, triethanolamine and oleinic acid are added in sequence and placed into a reaction kettle with the rotational speed of 80 to120 circles per minute to be heated and stirred, and when the temperature reaches 80 DEG C, heat preservation and continuous stirring are carried out for 60 minutes; and then the temperature is reduced to 70 DEG C, polyethyleneglycol, benzotriazole and isothiazolinone are added in sequence, the temperature is maintained at 70 DEG C, and stirring is carried out for 90 minutes, after that, heating is stopped, stirringis carried out while water is added until the solution is diluted to be light tan, so that the aqueous hot-rolling functional liquid is prepared. The aqueous hot-rolling liquid provided by the invention is diluted by water to be a rolling functional liquid with the volume concentration of 2 to 6 percent. The rolling liquid is simple to use and convenient to operate, is nontoxic and free of pungent odor and oil smoke in a hot-rolling process, and further enhances the corrosion resistance of rolled pieces.

Description

technical field [0001] The invention relates to the technical field of lubricants, which are used for cooling and lubricating during the hot rolling of steel products, in particular to an aqueous molybdenum-containing hot rolling functional fluid and a preparation method thereof. Background technique [0002] With the development and application of new hot rolling technology and the continuous improvement of users' requirements for steel quality, the lubrication technology of hot rolling process has not only been paid more and more attention, but also as an important process measure, it is constantly being developed and improved in practice. At present, hot-rolling oil is mostly used as lubricant for steel hot-rolling. However, there are many problems in the use of traditional hot-rolling oil, such as high oil consumption during the rolling process, the generation of smoke makes the production environment harsh, residues pollute the cooling water, and the steel slows down aft...
