Abstract

The invention discloses wire-drawing powder with a good lubricating effect. The wire-drawing powder is prepared from calcium hydroxide, sodium hydroxide, stearic acid, vegetable fat, paraffin, activated talcum powder and silicon dioxide cladded nano-attapulgite in a mixing mode. According to the prepared wire-drawing powder with the good lubricating effect, the mobility is good, the weight change is small after an ignition test of 500-600 DEG C, in the use process, the possibility of mutual gnawing soldering type contact between a steel wire and the contact surface of a die can be greatly reduced, thus the friction resistance can be remarkably reduced, and the good lubricating effect can still be kept under high temperature. The wire-drawing powder is low in loss rate and long in service life, and the cost is greatly reduced. Besides, by utilizing the prepared wire-drawing powder for wire-drawing lubrication, the wire-drawing quality is also improved remarkably.

Description

technical field [0001] The invention belongs to the technical field of wire drawing powder, and in particular relates to a wire drawing powder with good lubricating effect. Background technique [0002] Drawing powder, commonly known as dry "drawing lubricant", also known as "drawing lubricant powder", is usually divided into calcium-based drawing powder and Naji drawing powder. In the deformation process of steel wire cold drawing, it can play a lubricating property, greatly reduce the friction coefficient, save energy consumption, prolong the service life of the wire drawing die, and in the high-speed drawing process, the faster the drawing speed, the better the lubricating effect. When drawing low-carbon steel wire, high-carbon steel wire, special alloy steel wire, and stainless steel wire, it can make the steel wire form a lubricating film with the deformation temperature of the steel wire during the high-temperature and high-pressure drawing process to protect the finis...
