Unless it's got a power supply for control electronics that depends on the 50hz, it might work fine on 60hz; the actual elements and whatnot would work on either 50 or 60.
The power supply itself may well be designed to run on either frequency; it may have it's own label with it's specs on it inside the stove, whereever the main electronics are.
If it's old type with electromechanical controls or clocks, they'll run faster.
That said, if you want to use a converter on the whole unit for simplicity, it's going to have to be capable of handling the full load of all the elements on at the same time, in case you ever end up using it that way. I don't know that the stove would actually pull it, but the outlet I have in my kitchen is 240V 50A, which multiplies out to around 12kW.
The link you have there is only good for 250W, so it would probably run just the control electronics, as long as you can isolate those from the elements so they can run on different AC supplies.
