Abstract

The invention discloses a high wear-resistant ceramic composite guide roller and a preparation method thereof. It includes a roller core and a ceramic ring, and the ceramic rings are arranged side by side on the roller core at equal intervals, and the spacing is in the range of 1cm-5cm; the ceramic ring is fixed on the roller core through a fusion base; the inner surface of the ceramic ring is evenly distributed There is a gap. In the present invention, the guide roller adopts ceramic rings arranged side by side at equal intervals on a roller core, and the ceramic ring is fixed on the roller core through a fusion base; the peripheral side of the ceramic ring is used as a working surface, and the fusion base is used as a composite base material. The ceramic ring is made of titanium carbide ceramics or titanium silicon carbide or alumina ceramics or zirconium carbide ceramics, which has high structural hardness and strong wear resistance, which improves the service life of the guide roller.

Description

technical field

[0001] The invention belongs to the technical field of rolling mill guide rolls, and in particular relates to a high wear-resistant ceramic composite guide roll and a preparation method thereof. Background technique

[0002] During the wire rolling process, the steel billet passes through the guide device at a relatively high temperature (900-1250°C) and at a high speed (above 50m / s). Cooling water with a certain pressure is sprayed on the surface. Therefore, at a relatively high temperature, the guide device not only has to bear the shock of rapid cooling and heat, but also bears the impact load imposed by sliding friction and wear and the entrance of the billet. The working conditions are very harsh. When the heat dissipation of the guide roller is not smooth, It is easy to cause loss or even failure of the guide roller.

[0003] At present, most of the guide rollers are made of heat-resistant steel and other metal materials. Due to the low hardness and w...
