An auto transformer will do this job very nicely.
To convert 415 volts to 220 volts, you use a stepdown transformer of an appropriate rating. Since this is a three phase circuit, you need a three phase transformer, or three one phase Transformers.
Use a transformer.
AnswerA three-phase, four-wire, system with a line voltage of 415 V has a phase voltage of 240 V. 240 V is well within the UK's legal voltage-variation allowance of 230 V (+10%/-6%). So, you don't need to 'convert' anything. If the line voltage (line-to-line) is 415 V, then the phase voltage (line-to-neutral) is already 240 V which is close enough to 230 V for your appliances to operate normally. So, you DON'T need to use a transformer!
If you only have 415V 3 phase available you will need a step down transformer to step the voltage down to 230V.
AnswerIf you are asking how you can connect a 230-V load from a 415-V three-phase supply, then the answer is straightforward.
415-V is the nominal line voltage for a star (wye) connected three-phase supply in the UK (strictly, its now labelled 400 V to harmonise with EU regulations, but it's still actually 415 V!), which means its phase voltages are a nominal 240 V (again, officially labelled 230 V for harmonisation with EU regulations).
So, you simply need to connect your three-phase load between of the supply's line and neutral conductors (i.e. A-N, B-N, and C-N). A transformer is unnecessary.
Voltages are converted by the use of a transformer. The two voltages 208 (North American) and 415 (UK, European) are not a standard transformer configuration. The transformer would have to be specially wound to achieve this transformation.
An auto transformer will do this job very nicely.

415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.
I depends on what you are connecting to it but you only need 1 of the phases providing you can get to a neutral

Va=volts x amps. The K stands for one thousand. So 1 Kva is one thousand watts. So 415v times 120a= 49,800 what's. You divide that by a thousand and you get 49.8. So it would be 49.8 Kva.
Typically single phase motors go up to 10hp. Wouldn't be very efficient at about 100 amps. A 20hp 3 phase motor at 230v pulls 52 amps. The 10hp single phase 230v pulls 50 amps.
415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.

In India its 415V, 50Hz.
Three-phase voltage in Germany is 400V, single-phase voltage is 230V.

I dont know if you can actually convert the oven's wiring from 3-phase to single phase. You can, however, convert the single phase circuit that will feed the oven to a 3-phase system. To this you will need a phase converter. Now, where to purchase such an item, and how much they cost? i have no idea.

The voltage of three phase is 415v and the colours are brown black and greyAnswerThe nominal line voltage is 400 V, and the nominal phase voltage is 230 V.
Yes, it will run drawing little more extra current in similar conditions. The motor is expected to be running in lesser rpm as well.
