Description
Technical field
Roller equipment technical field is the utility model is related to, more particularly, to a kind of pearlitic spheroidal graphite with refrigerating function
Grain roll.
Background technology
The alloying elements such as nickel, chromium, molybdenum are added in spheroidal graphite cast-iron, pearlitic ductile iron roll is obtained by special thermal treatment.Pearl
Body of light spheroidal graphite roll has good intensity, high-temperature behavior and anti-accident performance, working lining hardness drop small.Roll is to roll
The important process equipment of steel production, roll cooling is link important in steel rolling process, in the hot rolling, roll work
When directly contacted with steel and produce sliding friction, the temperature of roll is very high, it is necessary to cool down in time, existing cooling effect of roller
Difference, roll inhomogeneous cooling is even, groove serious wear, and single groove steel transportation amount is very low, or even generation high temperature is adhered, roll loses flesh and roll breakage
Phenomena such as；Simultaneously inadequate in cooling degree, easily there is thermal stress damage in pass edge, and not only roller consumption is high, and production cost increases
Add, it is also serious to reduce product surface quality, it is damaged the performance of enterprises.
Utility model content
The technical problems to be solved in the utility model is：It is poor in order to solve existing cooling effect of roller, roll inhomogeneous cooling
The problem of even, now provide a kind of pearlite ductile iron roll with refrigerating function.
Technical scheme is used by the utility model solves its technical problem：A kind of pearlite ball with refrigerating function
Graphite cast iron roll, including mandrel and the outer collars that is set in outside mandrel, the outer collars is fixedly connected on the mandrel, described
First annular cavity body is provided between mandrel and the outer collars, one end of the mandrel is provided with inlet opening, the inlet opening edge
Mandrel axle extends internally, and is axially arranged with some first through hole groups along it on the mandrel, the first through hole group is by some along core
The first through hole composition of axle circle distribution, the inlet opening are connected by the first through hole with the first annular cavity body,
The second toroidal cavity body is provided with the mandrel, the second toroidal cavity body is axially located the first annular cavity along mandrel
The centre position of body, offers some second through holes on the mandrel, second through hole by the first annular cavity body and
The second toroidal cavity body phase is intercommunicated, and the one end of the mandrel away from inlet opening is provided with apopore, and the apopore is along institute
Mandrel is stated to extend axially inwardly and connect with the second toroidal cavity body.
Because original cooling water is by one end entrance of roll, directly discharged by the roll other end so that roll is in cooling water
The temperature of input is low, and the temperature in cooling water outlet side is high, so that the roll both ends temperature difference is larger, so as to cause roll
Inhomogeneous cooling is even, and the utility model is being entered by the way that the second toroidal cavity body to be arranged on to the centre position of first annular cavity body
When water hole intakes, cooling water can be flowed into first annular cavity body by first through hole by the both ends of roll, while can rolled
The centre position of roller is entered in the second toroidal cavity body by the second through hole, and the coolant-temperature gage for so allowing for roll both ends is equal
It is even, furthermore the temperature among the temperature at roll both ends and roll also will not be poor too many, reduces the temperature difference of roll.
Manufactured for the ease of roll, further, the mandrel outer surface offers first annular groove, the core
The second annular groove is offered in the first annular groove on axle, is provided with and its phase in second annular groove
The snap ring matched somebody with somebody, the snap ring, which is located in the second annular groove, is provided with the 3rd annular groove, and second through hole is located at the card
On ring, second through hole connects the first annular groove with the 3rd annular groove.By opening up the first ring on mandrel
Connected in star, when being assembled with outer collars and first annular cavity body is formed, snap ring is half slide structure and connected by screw thread
On mandrel, the 3rd annular slot and the second annular slot on snap ring complement each other to form the second toroidal cavity body, drop significantly
Low roll causes difficulty.
The beneficial effects of the utility model are：The pearlite ductile iron roll that the utility model has refrigerating function makes
Used time, by the way that the second toroidal cavity body to be arranged on to the centre position of first annular cavity body, and cause cooling water by the
One through hole is entered simultaneously by the both ends of first annular cavity body, then reaches the second toroidal cavity body by middle second through hole, finally
Discharged by apopore, ensure roll both ends even water temperature, and reduce the temperature difference at roll both ends, avoid existing roll cooling
Effect is poor, and roll inhomogeneous cooling is even, groove serious wear, and single groove steel transportation amount is very low, in addition produce high temperature adhesion, roll lose flesh and
Phenomena such as roll breakage；Simultaneously inadequate in cooling degree, easily there is thermal stress damage in pass edge, and not only roller consumption is high, is produced into
This increase, also serious to reduce product surface quality, the problem of being damaged the performance of enterprises.
