Abstract
The invention relates to a steel-ceramic combined roller manufacturing method, which comprises the following steps: (1) a hollow ceramic roller body is manufactured; (2) supporting rings are processed; (3) a roller core is processed, and a hollow steel pipe or solid round steel of which the external diameter is smaller than or equal to the internal diameter of each supporting ring is manufactured into the roller core; and (4) assembly is performed: one supporting ring sleeves one end of the roller core, then the hollow ceramic roller body externally coats the roller core, the other end of the roller core is coated by the other supporting ring, the supporting rings are enabled to form a right angle with the ceramic roller body, and the inclined planes between the supporting rings and the roller body are closely fitted. The steel-ceramic combined roller manufacturing method has the beneficial effects that the ceramic roller body and the supporting rings are in close rigid contact; the stability is good during operation; the whole structural strength is high; the problems that when common ceramic and metal are combined, matching and ceramic fracture caused by inconsistent swelling coefficients under high temperature are solved; corrosion resistance and abrasion resistance are high; and the use cost is low.
Description
Technical field
The present invention relates to a kind of manufacture method of roller, particularly relate to the manufacture method of a kind of steel-ceramic combination roller.
Background technique
At present, roller is used for high temperature, corrosive environment, as annealing furnace, roller needs long-time running under the high temperature conditions, therefore roller needs resistance to oxidation, high temperature resistant, high temperature resistant creep, the requirement such as anti-corrosion, and known heat-resisting, Wearing-resistant roller adopts the ceramic coated layer of steel roller surfaces or uses full ceramic roller.Because the ceramic layer thickness of spraying is limited, and the structural strength of full ceramic roller is poor, cost is higher, in actual production practice, have certain narrow limitation.
Chinese invention patent CN 103350877 A discloses a kind of steel and ceramic combination roller, by steel liner, flexible material packed layer, pottery working surface three part composition, flexible packing material between steel liner and ceramic working surface plays both connections and makes up the two breathing amount change that temperature variation causes, and makes steel liner and ceramic working surface keep being connected and not because of the ceramic working surface of temperature variation spalling.Although solve part breathing problem, when the temperature difference exceedes design load, breathing quantitative change greatly still can spalling.And because interlayer flexibly connects, validity during operation can not be guaranteed, and overall construction intensity is poor.
Summary of the invention
The present invention is directed to existing ceramic coated-the high and existing steel-untight shortcoming of ceramic combination roller contact of steel rider short, full ceramic roller cost in sub-working life, provide the manufacture method of a kind of steel-ceramic combination roller.
The technological scheme of the above-mentioned technical problem of the present invention is as follows:
A manufacture method for steel-ceramic combination roller, is characterized in that, comprise following steps:
1) manufacture the ceramic body of roll: fire the one-body molded cylinder type hollow pottery body of roll, then annular cutting is carried out to the inside edge at ceramic body of roll two ends, make inside edge its central axis inclination 30 ~ 70 ° relatively of the ceramic body of roll;
2) process support ring: be processed into steel-made support ring, then along external diameter, annular cutting is carried out to support ring, the edge cuts Cheng Yuqi central axis of support ring is had the plane of angle, this angle and step 1) described in the inside edge of the ceramic body of roll equal relative to the angle of its central axis;
3) roller core is processed: make external diameter and be less than or equal to the hollow steel pipe of support ring internal diameter or solid round steel is roller core;
4) assemble: support ring is inserted in roller core one end, be nested in outside roller core by the hollow ceramic body of roll afterwards, the roller core the other end is inserted in another support ring, ensure support ring and the ceramic body of roll rectangular, and the inclined-plane of the two fits tightly, and is fixedly connected with by roller core with support ring.
Beneficial effect of the present invention is:
1) when there is thermal expansion in support ring and hollow ceramic roller, inclined-plane along setting slides, by the stress removal of thermal expansion, avoid the drawing crack problem that common steel group of ceramics component is common, in addition, inclined-plane can ensure roller at different temperatures, support ring and hollow ceramic roller, maintaining rigidness contacts, structural strength and good integrity, ensures the stability that roller runs and dimensional accuracy.
2) the combination body of roll provided by the invention is full ceramic material, and hardness is up to Mohs 9.5, thickness range 5-80mm, resistance to oxidation, high temperature resistant, high temperature resistant creep, anti-corrosion, long service life, and cost does not have full ceramic roller so high.
On the basis of appeal scheme, the present invention can also do following improvement.
Further, step 1) described in the ceramic body of roll inside edge relatively its central axis angle of inclination be 45 °.
Further, step 1) described in the material of the ceramic body of roll be selected from MgO, Al
