GWDL's independently developed patented technology for heating-uniform and energy-saving box-type electric furnaces adopts an innovative multi-zone independent temperature control system and three-dimensional thermal field optimization design, successfully solving industry problems such as poor temperature uniformity and high energy consumption in traditional box-type furnaces. Through a special layout of heating elements and a high-efficiency thermal insulation structure, this patented equipment achieves a temperature uniformity of ±1℃ in the working area, with an energy-saving effect of over 30%. It is particularly suitable for material heat treatment and sintering processes that require precise temperature fields, and is an important manifestation of GWDLTHERMO's technical strength in the field of industrial heating equipment.
