Specific embodiment
As shown in Figure 1 and 2, a kind of positioning tool grinding roll sleeve outer surface wearable ceramic bar, including upper positioning ring and lower fixed
Position ring passes through support lacing wire connection between upper positioning ring and lower positioning ring.The diameter of upper positioning ring and lower positioning ring is respectively
The diameter of roller set inner wall where top layer's wearable ceramic bar and lowest level wearable ceramic bar, every layer of ceramic rod position are straight
Diameter is identical as roller set casting mold corresponding position diameter.
Be respectively set upper layer cross lacing wire and lower layer's cross lacing wire in upper positioning ring and lower positioning ring, upper layer cross lacing wire and
It is connected between lower layer's cross lacing wire by diagonal bar.
On the one hand the upper layer cross lacing wire and lower layer's cross lacing wire of setting facilitate the lifting of positioning tool and will position work
It is filled with and is welded in the wearable ceramic bar Integral lifting to casting mold on the outside of positioning tool, on the other hand increase the whole of positioning tool
Body stability.
The positioning location mode for grinding roll sleeve outer surface wearable ceramic bar, includes the following steps:
Step 1: as shown in figure 3, the short transverse layering by wearable ceramic bar along positioning tool is welded on the outer of positioning tool
Side, wearable ceramic bar layering are successively welded to connect from bottom to up.Lowest level wearable ceramic bar interval is welded on lower positioning first
On the outside of ring, mode, the wearable ceramic bar of other layers and the wearable ceramic bar zigzag weld of its preceding layer are welded using manual electric arc welding
It connects to form the distribution of array grid, be welded between wearable ceramic bar using manual electric arc welding, top layer's wearable ceramic bar is welded on
On the outside of upper positioning ring.Wearable ceramic bar and the welding of upper positioning ring or lower positioning ring are adopted between wearable ceramic bar using form is fully welded
With spot welding form.The arc medial plane of wearable ceramic bar composition is consistent with the roller set medial plane of casting mold.
It makes radian and roller covers identical arc template, arc template is wood materials.In welding process, lowest level is first welded
Ceramic rod determines benchmark, subsequent weld in amendment with template, up to being soldered whole wearable ceramic bars, make one it is whole
Body.
Of same size, the wearable ceramic bar weldering of other layers at interval and wearable ceramic bar between bottom wearable ceramic bar
It connects between two wearable ceramic bars of its preceding layer.On the one hand it can guarantee the interval phase between the wearable ceramic bar of same layer
Together, on the other hand by the way that the wearable ceramic bar on upper layer to be welded between the wearable ceramic bar of lower layer, increase wearable ceramic bar it
Between bonding area.
When specific operation, it when bottom wearable ceramic bar is installed, is protected by the way that positioning wooden unit is arranged between wearable ceramic bar
The interval demonstrate,proved between wearable ceramic bar is consistent；When the wearable ceramic bar of other layers is installed, guarantee that layer is high by positioning wooden unit, thus
So that wearable ceramic bar is formed array distribution, to make the uniformity of roller sleeve abrasion resistant layer, part is prevented to be damaged.
In the present embodiment, it is rectangle that wearable ceramic bar, which is cross section, is conducive to install using the ceramic rod of the structure
Positioning and welding.
Step 2: the casting mold of mill roll sleeve is hoisted to by positioning tool and with the wearable ceramic bar of positioning tool one
It is interior, after upper layer cross lacing wire, lower layer's cross lacing wire and the diagonal bar inside positioning tool are cut off using gas flame cuttiug, poured with case
Note is an integral structure wearable ceramic bar with mill roll sleeve casting.
The positioning tool and positioning location mode of a kind of mill roll sleeve outer surface wearable ceramic bar of disclosure of the invention, design system
Make positioning tool, all wearable ceramic bars be fixed into an entirety in such a way that spot welding is piled up, then as lower core under
Into casting mold, realizes being uniformly distributed for wearable ceramic bar, the especially arrangement of roller set die joint ceramic rod, finally improve roller set
Casting service life.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as limitation of the invention, this hair
Bright protection scope should be with the technical solution of claim record, technical characteristic in the technical solution recorded including claim
Equivalents are protection scope.Equivalent replacement i.e. within this range is improved, also within protection scope of the present invention.
