SOLID FELT THERMAL FIELD MEMBER AND MONOCRYSTAL FURNACE

A solid felt thermal field member and a monocrystal furnace, relating to the technical field of monocrystalline silicon, for achieving the purpose of lowering costs under the condition of not changing existing heat preservation requirements. The solid felt thermal field member is arranged at intervals between an inner wall of a furnace body and a heater of the monocrystal furnace, and the solid felt thermal field member comprises a solid felt structure and a protection member provided on a first side of the solid felt structure, wherein the solid felt is a hard shaping felt, and the first side of the solid felt structure is the side of the solid felt structure close to the heater. Élément de champ thermique en feutre solide et four à monocristal, se rapportant au domaine technique du silicium monocristallin, permettant d'atteindre le but de réduction des coûts sans changer les exigences de conservation de chaleur existantes. L'élément de champ thermique en feutre solide est agencé à des intervalles entre une
