Problems solved by technology

At present, the aluminum plate rolling process oil is mainly composed of mixed hydrocarbons and additives (long-chain fatty acids, alcohols, esters). During the aluminum plate rolling production process, the following problems occur. First, the rolling stripes caused by insufficient lubrication frequently occur
Second, the distillation range of D100 base oil commonly used in cold rolling of aluminum plates is 230°C-265°C, while the additive is a mixture of fatty alcohol and synthetic ester, with a distillation range

Embodiment Construction

[0021] The present invention will be described in further detail below in combination with specific embodiments.

[0022] An aluminum plate rolling process oil for equal ratio volatilization and large reduction rate, which is composed of the following components by mass percentage: 97%-99% of base oil, 1%-3% of additives;

[0023] The mass content of n-alkanes in the base oil is more than 99.5%, and the rest are impurities. Calculated by mass fraction: normal alkanes contain C 13 Normal alkanes 25%~27.2%, C 14 Normal alkanes 39%~42.5%, C 15 Normal alkanes 27%~29.1%, C 16 The proportion of normal alkanes is less than 0.5%, and the balance is C 12 n-alkanes;

[0024] The additive is a mixture of trimethyl phosphate and triisobutyl phosphate, wherein, calculated by mass fraction: trimethyl phosphate accounts for 50% to 65%, and triisobutyl phosphate accounts for 35% to 50%; the distillation range of the additive is dry The temperature is less than 270°C, the acid value is l...

Abstract

The invention discloses geometric ratio volatilization aluminum plate rolling technical oil suitable for a heavy reduction rate and relates to the technical field of metal rolling lubrication technical oil. The rolling technical oil comprises, by mass, 97-99% of base oil and 1-3% of an additive. The base oil has n-alkane content of 99.5% or more. The n-alkane contains, by mass, 25-27.2% of C13 n-alkane, 39-42.5% of C14 n-alkane, 27-29.1% of C15 n-alkane, less than 0.5% of C16 n-alkane and the balance C12 n-alkane. The additive comprises, by mass, 50-65% of trimethyl phosphate and 35-50% of triisobutyl phosphate. The base oil and the additive are stirred and then are filtered to form the technical oil. The technical oil effectively improves PB, basically keeps a boiling range, realizes geometric ratio volatilization, greatly improves aluminum processing enterprise product quality and reduces a production cost.

Description

technical field [0001] The invention relates to the technical field of lubricating process oil for metal rolling. Background technique [0002] In the rolling process of aluminum plate, process lubrication plays a vital role. The use of process lubrication can effectively reduce the rolling pressure, reduce the friction coefficient, and improve the surface quality of the rolled material. In order to meet the requirements of high-precision rolling of aluminum sheets and high surface quality of aluminum sheets after rolling, modern cold rolling mills put forward high requirements for the use of rolling oil. Not only the refined mineral oil with high oxidation stability, low viscosity, high flash point, low sulfur and other characteristics is used as the base oil of rolling oil, but also various additives that can effectively reduce the aluminum sticking and friction coefficient of the roll are used. At present, the aluminum plate rolling process oil is mainly composed of mixe...
