Abstract
The utility model relates to an inlay cast liner composite straightening roller. A cast liner 1 is provided with an inlay slot 2 at least; the roller surface of the working layer of the straightening roller, and the cast liner of the straightening roller are cast into a composite structure. The composite straightening roller has the advantages of high strength, high toughness, good processing property, strong bonding, high work efficiency, low consumption, etc. The utility model not only can be applied to a cast iron straightening roller with low carbon and high chromium, but also applied to the straightening roller or roller with other materials.
Description
The utility model relates to the process spare part of stress metal processing; Particularly relate to the steel smoothing roll.
Smoothing roll is one of must obligato process spare part during shaped steel, steel pipe, strip material are produced, and it is according to the steel of aligning different cultivars, specification, and surperficial car becomes certain pass.The pass surface directly contacts with steel, bears under the effect of compression and rolls and sliding friction.Because compression is bigger, and the iron scale hardness of steel surface is very high, so roll surface wear is very serious.Domestic general shaped steel, steel pipe smoothing roll generally adopt chilled cast iron, alloy cast steel and alloy forged steel at present.Wherein the working lining of chilled cast iron and alloy cast steel smoothing roll is not wear-resisting; Alloy forged steel smoothing roll then costs an arm and a leg, and repairs difficulty, and anti-wear performance is also undesirable.At this problem, designer of the present utility model has developed the low carbon high chrome casting iron smoothing roll of a kind of high rigidity, high tenacity, high abrasion, the life-span of having improved smoothing roll effectively.But, this low carbon high chrome casting iron smoothing roll, if the overall structure of identical material has then not only increased difficulty of processing, material consumption is big too.Therefore, study a kind of smoothing roll of composite construction, then become an important content that improves in the smoothing roll problem.
The purpose of this utility model is exactly at above-mentioned needs, simultaneously, also is the same problem that exists at existing smoothing roll, a kind of high strength, high tenacity is provided, and is made of the smoothing roll of composite construction working lining roll surface and interior cover.
Basic solution of the present utility model is to adopt the method for inlay casting, casts an integral body with being nested in the working lining roll surface of smoothing roll and the smoothing roll.Firm for embedding casting back combination, be processed with more than one embedding casting groove at least interior putting.
Accompanying drawing 1 is the front view of an embodiment of the utility model, and accompanying drawing 2 is vertical views of A-A.
Specific embodiments of the present utility model is:
1, select cast steel, forged steel or cast iron materials for use, cover 1 in the needed smoothing roll is made in casting (forging);
2, be processed with more than one embedding casting groove 2 at least interior putting; (two of this example processing)
3, will be processed with the interior cover heating of embedding casting groove after, put into the die cavity of smoothing roll sand mold as core;
4, in sand mold, inject low carbon high chrome casting iron water, make to constitute compound working lining roll surface 3.
The compound straightening roller of the utility model embedding casting inner sleeve has high strength, high tenacity, good processability, inner sleeve and is combined firmly with the working lining roll surface, and the characteristics such as work efficiency height, consumption be low. Both applicable to the low carbon high chrome casting iron smoothing roll, also applicable to smoothing roll or the roll of other materials. Result on trial through inside and outside the province three producers to the utility model sample is not all found the phenomenon that inner sleeve and working lining roll surface come off.
Claims (1)
1, the compound straightening roller of cover in a kind of embedding casting is characterized in that being processed with at least more than one embedding casting groove 2 on interior cover 1, and the working lining roll surface 3 of smoothing roll is formed embedding casting composite construction with interior cover 1.
