Problems solved by technology

The addition of abrasive particles enhances the grinding ability of the brush wire, but it still does not effectively solve the weakness of the brush wire's poor temperature resistance, so it is not suitable for steel rolling finishing production lines such as hot rolling leveling units

Abstract

The invention relates to an abrasive containing brush wire for a rolled steel finishing production line and a preparation method for the abrasive containing brush wire and belongs to the technical field of rolled steel finishing. The brush wire comprises the following ingredients: 35% to 60% of nylon, 20% to 35% of thermoplastic resin with a continuous service temperature above 150 DEG C, 15% to 30% of abrasive grains, 0.2% to 2% of couplant, 0.2% to 1% of anti-aging agent and 0.2% to 1% of antioxidant. Through reasonably controlling the variety and amount of all ingredients in the brush wire,the brush wire can have excellent temperature resistance and fatigue resistance, softening of the brush wire does not occur under the condition of long-time high-speed working, and thus, the brush wire is applicable to rolled steel finishing production lines such as a hot-rolling leveling set. The brush wire is simple in preparation process and moderate in production cost, has a practical application value and is suitable for being produced in an enlarged manner.

Description

technical field [0001] The invention belongs to the technical field of steel rolling and finishing, and relates to an abrasive-containing brush wire used in a steel rolling and finishing production line and a preparation method thereof, in particular to a method for removing iron oxide scale and other attachments on the surface of a steel plate / strip on a steel rolling and finishing production line Abrasive-containing brush filaments and methods of making the same. Background technique [0002] In the steel rolling and metal processing industry, brush rolls are often used to clean the iron oxide scale or other residual attachments on the surface of the steel plate / strip, so as to avoid the iron oxide scale from adhering to the work rolls of the rolling mill, the work rolls of the tempering machine or the work rolls of the straightening machine, so that both It can improve the surface quality of steel and effectively increase the service life of work rolls. [0003] Steel wi...
