Abstract

The utility model aims at providing a novel loop guide roller for a high-speed wire rod rolling mill, wherein the novel loop guide roller is safe, reliable, convenient to disassemble, capable of effectively prolonging service life and reducing production cost and high in safety. An abrasion-resisting ring is arranged independently at the position with serious abrasion of the loop guide roller so that the abrasion-resisting performance is more than three times that of an exiting integral guide wheel, and only the abrasion-resisting ring is replaced when replacement is required. Therefore, service life of the guide roller is prolonged, and production cost is reduced to the largest extent.

Description

A kind of novel high speed rod-rolling mill kink deflector roll

Technical field

The utility model relates to a kind of deflector roll, is specifically related to a kind of novel high speed rod-rolling mill kink deflector roll.

Background technology

In order to realize the tension free rolling between unit or frame, whole production line had been utilized 5-7 group kinks in critical positions, makes rolled piece in the operation of rolling, form cover, regulates through the cover amount and realizes tension free rolling when high-speed wire rolling was produced now.Rolled piece loop-rising roll through kink the time holds up at a high speed, the rolled piece of high temperature forms cover.Loop-rising roll will be always and the rolled piece contact friction in whole Rolling Production process, and the loop-rising roll wearing and tearing cause the service life of loop-rising roll shorter than serious when rolling like this.And loop-rising roll is that integral surface built-up welding part will whole replacing when serious wear.Replacement cycle is short and will whole part replacement cause production efficiency reduction, production cost to increase.

Summary of the invention

A kind of novel high speed rod-rolling mill kink deflector roll that the purpose of the utility model provides a kind of safe and reliable, convenient disassembly, can effectively improve service life, reduces production costs, security is higher.

The purpose of the utility model is achieved in that a kind of novel high speed rod-rolling mill kink deflector roll; Comprise the kink deflector roll; The utility model also comprises split type wear ring, and described kink deflector roll is split type, is divided into kink deflector roll and following kink deflector roll; Last kink deflector roll is connected through two bolt with following kink deflector roll, and described wear ring is enclosed within on the kink deflector roll.

The utlity model has following advantage: life cycle is long, dismounting and change is convenient, use cost is lower.

Description of drawings

The former kink deflector roll of Fig. 1 sketch map;

The novel kink deflector roll of Fig. 2 sketch map;

Fig. 3 is the wear ring sketch map;

Wherein 1, the kink deflector roll, 2, the build-up wear-resistant layer, 3, bolt, 4, go up the kink deflector roll, 5, kink deflector roll down, 6, wear-resisting ring set.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

The utility model is optimized deflector roll under the situation that does not change original deflector roll installation dimension; The kink deflector roll adopts split-type design; The position of kink deflector roll serious wear is made wear ring separately; Anti-wear performance is former more than three times of one guide wheel, and when changing, only need change wear ring.So not only improve the service life of guide wheel but also reduced production cost to a great extent.Service life, dismounting and change convenience, use cost that the utility model has prolonged deflector roll are lower.

Claims

1. novel high speed rod-rolling mill kink deflector roll; Comprise the kink deflector roll; It is characterized in that: also comprise split type wear ring, described kink deflector roll is split type, is divided into kink deflector roll and following kink deflector roll; Last kink deflector roll is connected through two bolt with following kink deflector roll, and described wear ring is enclosed within on the kink deflector roll.
