The crystallization wheel has the beneficial effects that compared with the prior art, the crystallization wheel has high softening temperature and good thermal fatigue resistance, and therefore, the service life of the crystallization wheel is prolonged and simultaneously the production cost is reduced.
Description
Technical field
The utility model relates to wires and cables industry copper, aluminium bar continuous casting and tandem rolling machine, relates in particular to a kind of crystallizing wheel of continuous casting and continuous rolling mill.
Background technology
The crystallizing wheel of continuous casting and continuous rolling mill is also claimed cast wheel, and it is the key equipment on copper, the aluminium bar continuous casting and tandem rolling production line.In continuous casting and continuous rolling mill work, crystallizing wheel constantly rotates, and side inflow copper water or aluminium water, opposite side are solid copper bar or the output of aluminium bar, and water quench is arranged on every side.Crystallizing wheel is in the periodic cold and hot conversion, therefore requires to have the performance of good heat-conducting and thermal fatigue resistance.The whole nation in 2010 is used to produce 80% and 2,000,000 ton of aluminium bar of 4,400,000 tons of copper bars of electric wire all by casting and rolling process production, and the whole nation has 330 copper bar continuous casting and tandem rolling production lines and 200 aluminium bar continuous casting and tandem rolling production lines at present.
Domestic copper aluminium electric wire all is the red copper material with crystallizing wheel at present, though the red copper material has very high electrical and thermal conductivity performance, its intensity and softening temperature are low, and thermal fatigue resistance is poor.Copper water or aluminium coolant-temperature gage are very high, thus red copper material crystallizing wheel at high temperature the life-span very short.
The utility model content
The technical problem that the utility model will solve provides a kind of crystallizing wheel of novel continuous casting and continuous rolling mill, and compared with prior art it has the more excellent heat conductivility and the performance of thermal fatigue resistance, has longer service life simultaneously.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of crystallizing wheel of continuous casting and continuous rolling mill, comprise wheel body, and it is characterized in that said wheel body is an annular, the periphery of said wheel body is provided with groove, and it is processed by chromium zirconium copper product.
The annulus section of said wheel body is " U " shape, " H " shape or " M " shape.
The two sides of said wheel body also are provided with pit.
Said groove is rectangle, circular arc or trapezoidal.
The crystallizing wheel of said chromium zirconium copper continuous casting tandem mill, its chemical composition is by weight percentage: Cr:0.3～1.5%; Zr:0.03～0.3%; Cu: surplus.
The beneficial effect of the utility model is: the crystallizing wheel of the continuous casting and continuous rolling mill of the utility model adopts chromium zirconium copper product to process.In the two sides of wheel body the radiating effect that pit can increase crystallizing wheel is set.The advantage of chromium zirconium copper product is existing intensity and softening temperature than red copper high 50%; The heat-conductivity conducting performance that red copper about 85% is arranged again; Its softening temperature can reach 550 ℃, and the softening temperature of red copper has only 250 ℃, and high softening temperature can stop the crystallization again of material; Prevent grain growth, improve the ability of thermal fatigue resistance.Therefore the chromium zirconium copper product crystallizing wheel life-span significantly improves than red copper.

The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
The circle diameter of said wheel body 1 is φ 900mm～φ 3100mm.
The annulus section of said wheel body 1 is " U " shape.
Said groove 2 is trapezoidal.
The two sides of said wheel body also are provided with pit 3.
The manufacturing approach of the crystallizing wheel of the utility model continuous casting and continuous rolling mill is: vacuum induction furnace is with alloy melting, and---------------solid solution---cold looping mill rolling---Ageing Treatment is machined into finished size to hot looping mill rolling to 1250 ℃ of fusion temperatures at last in the forge hot cogging to be cast into alloy pig under the vacuum.
According to Cr content 0.65%, Zr:0.15%, all the other feed intake for Cu; With alloy melting, 1250 ℃ of fusion temperatures are cast into alloy pig under vacuum with vacuum induction furnace; Utilize forging press to carry out the forge hot cogging afterwards; 900 ℃ of forging temperatures, more successively through the hot looping mill rolling of 900 ℃ of temperature, 940 ℃ of solid solutions, cold looping mill rolling, under 440 ℃ of temperature Ageing Treatment 5 hours, be machined into finished size at last.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
