Abstract

The utility model provides a composite metallurgical roller comprising a core part and a working layer arranged outside the core part. A medium layer capable of being fused with the working layer and the core part is arranged between the core part and the working layer. The composite metallurgical roller is simple in structure and skillful in design, the reject rate caused by poor metallurgical combination is reduced to the controlled level of 6 percent or so due to the medium layer between the working layer and the core part; and the composite metallurgical roller is a new technical scheme, and is conveniently popularized.

Description

A kind of compound metallurgical roller

Technical field

The utility model relates to field of metallurgical equipment, especially relates to a kind of compound metallurgical roller.

Background technology

Existing composite casting roll is when casting, and is outer different from the material of core because working, and is prone to the molten defective of punching when filling out core, and these defectives cause:

1. metallurgical binding is insufficient, and some through detecting and verifying and can only use when rolling excellent line, rolling Strip accident rate is up to more than 40%;

2. metallurgical binding is inhomogeneous, and the excellent line that tandem rolling system is little can not be used, and can only scrap processing;

3. rush and occur some little casting flaws in the melting zone, these defectives form formation of crack and make and outerly leave with core segment under rolling pulsation and rotary power effect;

4. what appear at when larger defective is arranged peels off and roll breakage, causes rolling accident.

The utility model content

The purpose of this utility model is to provide a kind of compound metallurgical roller, can solve present compound metallurgical roller, and metallurgical binding is insufficient, the problem that metallurgical binding is inhomogeneous.

Technical scheme provided by the utility model is: a kind of compound metallurgical roller, and comprise core and be arranged on the working lining of core outside, be provided with the dielectric layer that can merge with working lining and core between described core and working lining.

Further, the fusion area of described core and dielectric layer is the 1-3 millimeter.

Further, the fusion area of described dielectric layer and working lining is the 1-3 millimeter.

The beneficial effects of the utility model are:

The utility model is simple in structure, designs ingeniously, is provided with dielectric layer at working lining and core, the bad quality that causes of original metallurgical binding can be scrapped like this to drop to 6% controlled left and right.This is a kind of new technical scheme, is convenient to promote.

Description of drawings

Fig. 1 is schematic diagram of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example only is used for explaining the utility model, is not be used to limiting scope of the present utility model.

A kind of compound metallurgical roller as shown in Figure 1 comprises core 1 and is arranged on the working lining 2 of core 1 outside, be provided with between described core 1 and working lining 2 can with the dielectric layer 3 of working lining 2 and core 1 fusion.

Core 1 is the 1-3 millimeter with the fusion area 4 of dielectric layer 3.

Dielectric layer 3 is the 1-3 millimeter with the fusion area 5 of working lining 2

The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.

Claims
