Abstract
The present invention relates to a kind of manufacture method of steel ceramic combination roller, comprise the following steps：1) the hollow ceramic body of roll is manufactured；2) process support ring；3) roller core is processed：It is roller core that external diameter, which is made, less than or equal to the hollow steel pipe or solid round steel of support ring internal diameter；4) assemble：Support ring is inserted in roller core one end, the hollow ceramic body of roll is nested on the outside of roller core afterwards, the roller core other end is inserted in another support ring, it is ensured that support ring and the ceramic body of roll are rectangular, and the inclined-plane of the two is brought into close contact.The beneficial effects of the invention are as follows:The ceramic body of roll and the close rigid contact of support ring, preferably, overall construction intensity is high for stability during operation, can avoid general ceramics and metallic combination in high temperature because of the cooperation of the inconsistent generation of the coefficient of expansion and ceramic splintering problem, but also with high anti-corrosion, wearability, use cost is relatively low.
Description
Technical field
The present invention relates to the manufacture method of a kind of manufacture method of roller, more particularly to a kind of steel-ceramic combination roller.
Background technology
At present, roller is used for high temperature, corrosive environment, such as annealing furnace, and roller needs longtime running under the high temperature conditions, because
This roller needs the requirement such as resistance to oxidation, high temperature resistant, high temperature resistant creep, anti-corrosion, and known heat-resisting, Wearing-resistant roller is to use steel roller
The ceramic coated layer in sublist face uses full ceramic roller.Because the ceramic layer thickness of spraying is limited, and the structure of full ceramic roller is strong
Spend poor, cost higher, have certain limitation in actual production practice.
The A of Chinese invention patent CN 103350877 disclose a kind of steel and ceramic combination roller, by steel liner, flexibility
Material packed layer, the ceramic part of working face three composition, the flexible packing material between steel liner and ceramic working face rises
To connection, the two changes with the two the breathing amount caused by temperature change that makes up, and makes steel liner and ceramic working face holding connection again
Not because of the ceramic working face of temperature change spalling.Although solving the problems, such as part breathing, when the temperature difference exceedes design load, breathing
Quantitative change greatly still can spalling.And because interlayer is flexible connection, accuracy during operation can not be guaranteed, overall construction intensity
Difference.
The content of the invention
The present invention is for the existing sub- service life of ceramic coated-steel rider is short, full ceramic roller cost is high and existing steel-pottery
Porcelain combination roller contacts untight shortcoming, and there is provided a kind of manufacture method of steel-ceramic combination roller.
The technical scheme of above-mentioned technical problem of the present invention is as follows：
The manufacture method of a kind of steel-ceramic combination roller, it is characterised in that comprise the steps of：

2) process support ring：Steel-made support ring is processed into, annular cutting then is carried out along external diameter to support ring, will be supported
The edge cuts of ring are into the plane with its center axis with angle, the angle and step 1) described in the ceramic body of roll inner side edge
Edge is equal with respect to the angle of its center axis；
3) roller core is processed：It is roller core that external diameter, which is made, less than or equal to the hollow steel pipe or solid round steel of support ring internal diameter；
4) assemble：Support ring is inserted in roller core one end, the hollow ceramic body of roll is nested on the outside of roller core afterwards, roller core is another
It is inserted in another support ring in end, it is ensured that support ring and the ceramic body of roll are rectangular, and the inclined-plane of the two is brought into close contact, by roller core and branch
Pushing out ring is fixedly connected.
The beneficial effects of the present invention are：
1) support ring is slided with hollow ceramic roller when occurring thermal expansion along the inclined-plane of setting, by answering for thermal expansion
Power removal, it is to avoid the common drawing crack problem of common steel ceramic combination part, in addition, inclined-plane can ensure roller in different temperatures
Under, support ring and hollow ceramic roller keep rigid contact, structural strength and good integrity, it is ensured that the stability of roller operation with
Dimensional accuracy.
2) the combination body of roll that the present invention is provided 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, service life is long, and cost is high not as full ceramic roller.
On the basis of appeal scheme, the present invention can also do following improvement.
Further, step 1) described in the inside edge of the ceramic body of roll with respect to its center axis angle of inclination be 45 °.
Further, step 1) described in the material of the ceramic body of roll be selected from MgO, Al2O3、ZrO2、SiO2、BN、B4C、SiC、
Si3N4, silicate, the one or more of borate.
Further, the thickness of the ceramic body of roll is 5-80mm.
