Abstract
The utility model discloses a high wear resistant alloy ring roller, which comprises a roller body consisting of an inner roller ring and an outer roller ring. The outer roller ring and the inner roller ring are connected with each other by a support rib, a key groove is arranged on the inner roller ring, and a wear resistant ring is fixedly sleeved on the outer roller ring. The high wear resistant alloy ring roller solves the problems of difficulty in wear resistance and high consumption of a roller body, and is simple in design and reasonable in structure. Besides, the wear resistant ring is combined with the roller body, so that wholeness and stability of the roller are improved.
Description
Technical field
The utility model relates to technical field of steel rolling, specifically belongs to high-wear-resistant alloy ring roller.
Background technology
Parts such as cover are carried, risen to the combined type that use in a kind of steel-rolling cooling bed zone that is used for iron and steel enterprise of roller, and the roll wear consumption rate is bigger, normally in the body surface built-up welding, spraying, the mode that plating is oozed improves the wearability of the body of roll, but existing roller wears no resistance unstable properties.
The utility model content
The purpose of this utility model provides high-wear-resistant alloy ring roller, and solve the roller body of roll and be difficult for the big problem of wear-resisting consumption, simplicity of design, rational in infrastructure, wear ring and body of roll combination, the globality and the stability of raising roller.
The technical solution adopted in the utility model is as follows:
High-wear-resistant alloy ring roller comprises the body of roll, and the body of roll is made of interior collars and outer collars, connects by supporting rib between outer collars and the interior collars, has keyway on the interior collars, is installed with wear ring on the described outer collars.
Described wear ring is the antifriction alloy ring.
The described body of roll is the spheroidal graphite cast-iron body of roll.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model adopts separately to be made the body of roll and high-wear-resistant alloy ring two parts, the body of roll adopts the ductile cast iron material manufacturing identical with former roller, body of roll external diameter is than former roller reduced diameter, wear ring adopts the high-wear-resistant alloy manufacturing, after the internal diameter of wear ring and body of roll external diameter adopted interference fit to carry out machining, after the wear ring heating, edge increased on the body of roll, make wear ring cooling back be combined into whole roller, thereby reach globality and the stability that improves roller with the body of roll.Wearing layer gets the thickness thickening and prolongs service life.Reduce production costs, its working position is coated fully by the high-wear-resistant alloy ring, and the body of roll of spheroidal graphite cast-iron manufacturing is not worn, so the body of roll repeatedly uses after can changing alloy hoop.Thereby save the maintenance cost of production line.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a plan structure schematic diagram of the present utility model.
The specific embodiment
Referring to accompanying drawing, high-wear-resistant alloy ring roller, comprise the spheroidal graphite cast-iron body of roll 1, the spheroidal graphite cast-iron body of roll 1 is made of interior collars 2 and outer collars 3, connects by supporting rib 4 between outer collars 3 and the interior collars 2, have keyway 5 on the interior collars 2, be installed with antifriction alloy ring 6 on the outer collars 3, the spheroidal graphite cast-iron body of roll 1 is coated fully by antifriction alloy ring 6, and the spheroidal graphite cast-iron body of roll 1 is not worn, so the spheroidal graphite cast-iron body of roll 1 repeatedly uses after can changing antifriction alloy ring 6, thereby maintenance cost of saving production line.
Claims (3)
