SU635125A1 - Coolant for cold pressure shaping of metals - Google Patents

Description

The invention of the industry to metallurgical Koii industry and can be used for the production of pipes, drawing pipes and carbon steel grades.

Lubricant for cold deformation of pipes (dragging) must meet basic requirements, namely, an emoticon should have less motivation than the metal to be processed, must be movable and treated and prevent the metal of the pipe from being irradiated to the tool, i.e. it must have high screening and Lubricating properties, with the subsequent therm treatment T1), to destroy and get bright and light surfaces without black deposit, which is formed as a result of coke formation of lubricating agents.

The presence of coke formation products on the outer surface hides its defects, the timely singing of which is unacceptable for sprapal pipes.

Known lubricants for cold pressure treatment of metals based on mineral oil with the addition of axillary tetramerogne 1, butt 2.

However, irp-1peeei of such lubricants that provides the required quality of the surface to be readable, since irn reivxio processing) forms a solid black screen.

In order to improve the quality of 1bat1; iioBcpxiiocTH P1, a contribution is made of a lubricant and a base of chlorinated paraffin, which additionally contains 1; 1yg ethanol.

Ethanolamine1-5

Chlorinated paraffin up to 100

Mono-, dp- and triethanolamines can be used as ethanolamines.

The main function of ethanolamine in lubrication is that, due to their presence, the surface of the stretched tubes after the heat treatment process is light, without contamination and dark films of grease residues.

In addition, ethanolamine as a surface-active fabric increases the lubricating properties of the lubricant, improves the surface-molecular and shielding properties of the lubricant and friction conditions in the deformation center.

Chlorinated iarafin in lubrication is used as an anti-seize agent and high pressure additive.

The lubricant is prepared by mechanically mixing the components in appropriate quantities in any order at room temperature. After long-term storage of the grease, it must be mixed again before use.

In tab. 1 shows samples of chlorinated paraffin-based lubricants with the addition of ethanolamines.
