Hi I live in Turkey and got some lily bulbs last year, I planted them 3 and 3 in large pots. Now its time to take them up and put them in the fridge. But there were still fresh roots in the bottom of pot and there were so much roots (dry ones) that all had grown together. looks like a wigg that never been comed. Can I cut this dead roots? I took most of the soil away and put them back in the pot so the roots thats not dead can dry out compleatly.
Last summer I wonderful 12 cm large at first darker pink, and later redish to maron flowers. Do you think I`m doing the right thing? Should I cut the remiding roots?

When bulbous plant in dormancy or going to, you should cut off the watering. This will make bulbs save the energy to chunk up the bulbs and all the roots and above ground part will wilt and die off, only the bulb will be big and ready for dormancy.

For the zones where the winter temperature is not as cold for these plants need cold period of winter, the best way is forcing plants go in dormancy then in fridge to simulate winter. Use new soil to plant the bulbs if possible. If the bulbs are too many, could divide the bulbs to plant them with reasonable spacing between bulbs.

Lilium bulbs are a little different than bulbs that go completely dormant. By all means, remove the dead roots. But the live roots are needed for the following growing season. Lilium bulbs don't need to be stored in the fridge with soil in a pot, but they need to be in a closed bag, with just enough moisture to keep bulb and roots from dehydrating. Optimum temperature for Lilium bulbs is minus 1 to 4°C.

Because you mentioned in your description of the roots that they are like a wig, that many roots usually occur in Amaryllis, Habranthus and Lycoris species, rather than in Lilium. I just want to make sure we are talking about the correct plant.
