Intensity height is connect, ensure that the bonding quality of annular type core.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of present invention splicing disk.
In figure: 1- anchorage clip, 2- positioning ring, 3- limit card slot (3), 4- drip irrigation hole.
Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
As shown in Figure 1, the present invention provides a kind of joining method that several type core loose piece splicing groups are circularized to type core,
The following steps are included:
Splicing disk is provided, splices the positioning ring 2 for being provided with closed ring on disk, is provided with several on positioning ring 2
Limit card slot 3,3 quantity of limit card slot is equal with type core loose piece quantity, and 3 inner surface contour of limit card slot and type core loose piece surface
Portion profile profile unanimously corresponds to one by one, and first type core loose piece one-to-one correspondence is set within limit card slot 3, will using bonding agent
Two neighboring type core loose piece bonds together, and after bonding agent condensation, all models core loose piece splicing group circularizes type core.
Further, it is preferable to which the configuration raw material of bonding agent includes bauxite and silica solution.Using technical solution of the present invention,
The bonding agent can high temperature resistant, setting time is fast, improves splicing packaging efficiency, and bonding agent adhesive strength is high, ensure that ring
The bonding quality of shape type core.
Furthermore it is preferred that 3 quantity of limit card slot is 10.The material of type core loose piece is ceramics.
In addition, being also equipped with multiple anchorage clips 1 on splicing disk, 1 quantity of anchorage clip is equal with type core loose piece quantity, if will
