The beneficial effects of the utility model are: by arranging radiating groove at die body outer surface, increase the area of dissipation of steel ingot side, after in pouring molten steel to die body inner chamber, accelerate the radiating rate of molten steel, outermost molten steel is made to cool formation chill fast, and accelerate the thickness growth rate of chill, make it be enough to bear the static pressure in molten steel casting process, prevent chill from cracking.Meanwhile, radiating rate also can reduce the composition segregation of steel ingot soon, and reduces mould consumption.
Accompanying drawing explanation
Fig. 1 be the utility model external recessing round steel ingot mould partly cut open schematic diagram;
Fig. 2 is the top view of the utility model external recessing round steel ingot mould.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1 and Figure 2, external recessing round steel ingot mould of the present utility model, comprises die body 1 and hanger 2, and described die body 1 is provided with inner chamber 11, and described hanger 2 is fixedly installed in die body 1 sidewall, and the outer surface of described die body 1 is provided with radiating groove 3.
Die body 1 upper end is suitable for reading 12, and lower end is end opening 13, and during cast, the rise hole that molten steel is placed in base plate from end opening 13 injects inner chamber 11; After round ingot cooling, utilize hanger 2 to be sling by round steel ingot mould, make the round ingot demoulding.By the arranged outside radiating groove 13 at die body 1, increase the area of dissipation of round ingot side, after in pouring molten steel to die body inner chamber, accelerate the radiating rate of molten steel, make outermost molten steel cool formation chill fast, and accelerate the thickness growth rate of chill, make it be enough to bear the static pressure in molten steel casting process, prevent chill from cracking, ensure the surface quality of round ingot.Meanwhile, radiating rate also can reduce the composition segregation of steel ingot soon, and reduces mould consumption.The utility model, require not bery harsh to pouring temperature and poring rate, steel ingot central dense degree is high, and tube rolling recovery rate of iron is high, can realize the batch production of the multi-plate cast of large smelting furnace one stove.
Radiating groove 3 can be arranged along die body 1 circumference, also can arrange in the shape of a spiral, and its cross section can be the shapes such as semicircle, in order to ensure that heat radiation evenly, reduces difficulty of processing.Described radiating groove 3 is arranged along the axis of die body 1, and the cross section of described radiating groove 3 is rectangle or bottom land cross section is semicircle, and bottom land and cell wall junction rounding.
Described radiating groove 3 quantity is 12 ~ 50, and is evenly distributed on the outer surface of die body 1.The degree of depth of described radiating groove 3 is 8 ~ 60mm, and the distance between center line of adjacent two radiating grooves 3 is 50 ~ 260mm, and the width of radiating groove 3 is 10 ~ 200mm.The quantity of radiating groove 3 and size are selected according to the actual specification of round ingot: if the diameter of round ingot is comparatively large, then radiating groove 3 quantity should be more, or the size of radiating groove 3 is larger; If the diameter of round ingot is less, radiating groove 3 quantity should be less, and the size of radiating groove 3 should be less.To ensure that the size and number of radiating groove 3 can not impact the intensity of die body 1 simultaneously.
In order to improve the intensity of die body 1, the notch of described radiating groove 3 and the intersection rounding in adjacent two faces.Fillet can reduce stress and concentrate, and reduces radiating groove 3 to the impact of die body 1 intensity.
The inner chamber 11 of described die body 1 is positive truncated cone-shaped, and the described internal diameter of suitable for reading 12 is less than the internal diameter of end opening 13.This shape is conducive to the demoulding of round ingot.As preferred technical scheme, the tapering of described inner chamber 11 is 0 ~ 0.6%.Round ingot profile and the current continuous cast round billets shape of die body 1 production of this tapering are close, are applicable to polytype Tube Rolling Train tube rolling.
In order to alleviate the weight of die body 1, described die body 1 suitable for reading 12 wall thickness be less than the wall thickness of end opening 13.The ratio of the described wall thickness of suitable for reading 12 and die body 1 external diameter mean value is 0.08 ~ 0.12; The wall thickness of end opening 13 and the ratio of die body 1 external diameter mean value are 0.10 ~ 0.14.Die body 1 external diameter mean value is 1/2nd of minimum outer diameter and maximum outside diameter sum.Suitable for reading 12 specifically select according to the specification of round ingot and steel grade with the size of end opening 13.
