It depends, which kind of Oziexplorer maps you are using.
Look at
OsmandMapcreator. Perhaps you are lucky and your OziMaps use the the same sources.
You can use ozimaps on android with
Androzic.
There is also the possibility to convert OziMaps to oruxmaps

It could be, that there is a step in this process, which produce the tiles you are need for osmand. You have to test this.
