Description
Technical field
The present invention relates to mill and calender technical field, be specifically related to a kind of mill or rolling mill roller and the manufacture method of a kind of mill or rolling mill roller.
Background technology
Mill and calender are the visual plants of rubber processing, it is widely used, mill is mainly used in the mixing of sizing material, the calender sizing material to mixing carries out compacting, extension, roller is the main parts size of mill and calender, the corrosion of sizing material and rubbing action and bigger horizontal pressure can be subject at work, for ensureing the machining accuracy of goods, it is desirable to roller is it is necessary to have sufficiently large intensity, rigidity and higher case hardness and wearability. According to different technological requirements, roller needs when rolling sizing material sizing material to be heated or lowers the temperature. Owing to substantial amounts of heat can be produced in the interaction process of sizing material and roller, the too high quality that can affect sizing material of temperature and performance, it is therefore desirable to roller has the good effect that cools.
In prior art, in roller, arrange medium runner sizing material is heated or lowers the temperature, roller many employings hollow type in traditional mill or calender and two kinds of temperature control modes of hole drilling type, material mostly is chilled cast iron, and case hardness is big, and wearability is good, but there is following defect: one, the fragility of chilled cast iron material is big, internal toughness is poor, and intensity is not enough, is susceptible to fracture when horizontal pressure is bigger; Two, the roller elastic modelling quantity that chilled cast iron makes is less, poor rigidity, and under horizontal pressure effect, deflection is bigger; Three, hollow type roller heat exchange effect is poor, drilled roll needs deep hole processing and inclined hole, and difficulty of processing is big, processing cost is high, and cooling effect is general, it cannot be guaranteed that the uniformity of roller temperature distribution, and monolithic construction limits the feasibility of water channel of heat processing better effects if.
Summary of the invention
It is an object of the invention to provide that a kind of surface abrasion resistance is good, good rigidly, intensity high, heat transfer effect substantially, the manufacture method of the mill of uniformity of temperature profile or rolling mill roller and roller.
To achieve these goals, the technical solution of employing is the present invention:
