Abstract
The invention discloses a steel rolling cord thread tungsten carbide roll collar recipe which comprises the following ingredients in percentage by weight: 90.5 to 92.5 percent of WC, 3.5 to 4.5 percent of Co, 3.5 to 4.5 percent of Ni, 0.2 to 0.5 percent of TiC, 0.2 to 0.5 percent of CrCo and 0.1 to 0.3 percent of VC. The recipe has the advantages that the raw material composition and the ingredient proportioning of a tungsten carbide roll collar are improved, so the tungsten carbide roll collar has internal conditions for internal organizational structure formation required by the use performance, and can greatly improve the rolling quantity of single high-carbon steel of a single rolling tank when applied to the conditions of cooling water with the alkaline PH value of the water quality and the water temperature lower than 32 DEG C. Compared with the rolling quantity of the tungsten carbide roll used in the same industry, the rolling quantity of the roll collar can be increased by more than one time.
Description
Technical field
The present invention relates to a kind of steel rolling cord carbon tungsten roller ring prescription.
Background technology
The wear resistance of collars directly influences the surface quality of wire product and the production operational availability of milling train, therefore, the high-speed rod-rolling mill of China's introduction in recent years especially employed collars of variety steel finishing mill is the carbon tungsten roller ring of import mostly, the price of every roll is all very expensive, has increased production cost virtually.And carbon tungsten roller ring is later in the time of China's exploitation, the production technology of collars manufacturer is backward relatively, the surface quality and the inner quality of institute's production roll are all relatively poor, tissue looseness causes roll to wear no resistance, serious wear and roller crushing rate height, the amount of rolling of single roller and single groove is less, is difficult to satisfy the service requirements of high-speed wire rolling.On the other hand, the high-speed rod production development is swift and violent, and not only speed is more and more higher, the specification accuracy requirement is more and more tighter, kind is more and more simultaneously, and the intensity and the hardness of product are also more and more higher, influence the main bottleneck of product production and operating rate of rolling mill thereby the collars quality has been become.
Produce simple only the tackling key problems of producer of carbon tungsten roller ring at present from forming technology, the isostatic pressure aspect of collars, and seldom study from aspects such as the working condition of carbon tungsten roller ring and chemical ingredientss, therefore can't fundamentally solve the use properties problem of carbon tungsten roller ring always, thereby make the over-all properties that how to improve carbon tungsten roller ring become a difficult problem that needs to be resolved hurrily.
Summary of the invention
The object of the present invention is to provide a kind of steel rolling cord carbon tungsten roller ring prescription, it is all relatively poor effectively to solve existing steel rolling cord carbon tungsten roller ring surface quality and inner quality, tissue looseness causes roll to wear no resistance, serious wear and roller crushing rate height, the problem that the amount of rolling of single roller and single groove is less.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of steel rolling cord carbon tungsten roller ring prescription, comprise following component, the each component weight percent is: WC 90.5～92.5%, Co3.5～4.5%, Ni 3.5～4.5%, TiC 0.2～0.5%, CrC 0.2～0.5%, VC 0.1～0.3%.
Preferably, the each component weight percent is: WC 90.5%, Co 4.5%, Ni 4.5%, TiC 0.2%, CrC 0.2%, VC 0.1%; Can reach the steel rolling cord carbon tungsten roller ring prescription of better performance.
Preferably, the each component weight percent is: WC 92.5%, Co 3.5%, Ni 3.5%, TiC 0.2%, CrC 0.2%, VC 0.1%; Lower-cost steel rolling cord carbon tungsten roller ring prescription.
Preferably, the each component weight percent is: WC 91%, Co 4%, Ni 4%, TiC 0.2%, CrC0.5%, VC 0.3%; Take into account the steel rolling cord carbon tungsten roller ring prescription of performance and cost.
Preferably, the each component weight percent is: WC 92%, Co 3.5%, Ni 3.7%, TiC 0.3%, CrC 0.3%, VC 0.2%; Take into account the another kind of steel rolling cord carbon tungsten roller ring prescription of performance and cost.
Compared with prior art, advantage of the present invention is: be on the basis of main raw material with the wolfram varbide, the element cobalt and the nickel that have not only added Wimet phase with fabulous adhesive property, and be added with titanium carbide, the mixture of chromium carbide and vanadium carbide, thereby the raw material that has improved carbon tungsten roller ring is formed and composition proportion, make it possess the internal condition of the internal organizational structure formation of satisfying the use properties needs, be applied in the water quality pH value and be alkalescence, water temperature is lower than under the condition of 32 ℃ of water coolants, can improve the amount of rolling of roll list groove single high carbon steel greatly, compare with the tungsten carbide roll that the same industry is used, the amount of rolling of collars can be enhanced about more than once.
