Description
Technical field
The utility model belongs to technical field of heat treatment, and in particular to a kind of three bearing hollow ceramic hearth rolls.
Background technology
Silicon steel is silicon content in 3% ~ 5% or so the, Antaciron of other mainly iron.It is divided into orientation silicon steel and No yield point silicon
Steel, it is electric power, electronics and the indispensable important soft magnetic alloy of war industry.Silicon steel sheet is divided to two kinds of cold rolling, hot rolling, and use is more
Be cold-reduced silicon sheet.Cold-reduced silicon sheet has excellent magnetic property along rolling direction, not only has high saturation magnetic in high-intensity magnetic field
Flux density and low iron loss, and also have good magnetic in low-intensity magnetic field (initial permeability is big).This is due to cold-rolling process mistake
Journey reduces impurity content in steel disc, and coarse grain is caused in steel disc, causes magnetic conductivity to increase, and magnetic hystersis loss reduces.
Wherein, the production of high magnetic induction grain-oriented silicon steel comprises the following steps：
1. normalizing, workpiece to be added is heated to high temperature and completes the workpiece of austenitizing, is directly cooled down in atmosphere, with
Obtain tiny pearlitic structrure；Pickling, after normalizing, it is acidified by descaling mill and hydrochloric acid tank, removes the oxide of hot rolled strip, with
The defects of preventing cold rolling finished surface；
2. cold rolling, the workpiece to be added after normalizing pickling is subjected to cold rolling under the conditions of 100 DEG C；The rolling of cold-reduced silicon sheet edge
There is excellent magnetic property in direction, not only has high saturation magnetic flux density and low iron loss in high-intensity magnetic field；
3. decarburizing annealing and magnesium oxide coating；
4. annealed by high temperature bell-type furnace, to purify impurity；
5. stretch platform by stress after applying insulation material layer to be stretched；
6. trimming, crosscutting or rip cutting；
7. packaging.
In process of production, there was only two bearings for supporting and being driven the hollow ceramic hearth roll of the steel band in continuous oven
Support, and the position for installing bearing must be metal material, the connection between metal material and ceramic material is necessarily flexible coupling.
Such hearth roll can not use sprocket wheel to directly drive.Because without rigidity, if driving, it is necessary to which rigidity is set in addition
Supporting mechanism, it will result in complicated.
The content of the invention
The utility model for prior art driving hearth roll can not use sprocket wheel directly drive, it is complicated the problem of,
A kind of three bearing hollow ceramic hearth rolls are provided.
The utility model adopts the following technical scheme that：
A kind of three bearing hollow ceramic hearth rolls, including drive shaft, support shaft, hollow ceramic pipe and connecting pin, wherein, drive
One end of moving axis is the solid shafting provided with bearing I and bearing II, and the other end is provided with the sky of the convex shape matched with hollow ceramic pipe
Heart set I, one end of support shaft is the solid shafting provided with bearing III, and the other end is provided with the sky of the convex shape matched with hollow ceramic pipe
Heart set II, hollow sleeve I and hollow sleeve II are respectively equipped with shell fragment, the both ends point of hollow ceramic pipe with the inwall of bottom roller diameter parallel
Hollow sleeve I and hollow sleeve II are not stretched into, and connecting pin extends through connection end and the hollow sleeve II of hollow sleeve I and hollow ceramic pipe
With the connection end of hollow ceramic pipe.
Spacing between the bearing I and bearing II of described drive shaft one end is 115-117mm.
The shell fragment quantity of the inwall of hollow sleeve I is four, and two are respectively provided with along bottom roller axis is symmetrical above and below.
The shell fragment quantity of the inwall of hollow sleeve II is four, and two are respectively provided with along bottom roller axis is symmetrical above and below.
The shell fragment thickness is 1-2mm.
Described connecting pin one end is provided with jump ring.
The beneficial effects of the utility model are as follows：
For the utility model by increasing a bearing in the drive shaft end of hearth roll, such hearth roll can use sprocket wheel straight
Driving is connect, without setting rigid support mechanism in addition, simplifies the drive system of ceramic hearth roll.
