| description | The utility model discloses a box-type resistance furnace. The utility model relates to equipment for electrically heating workpieces. The utility model aims to solve the problem of poor heat preservation performance of a box-type resistance furnace. The technical problem of heat loss in the box-type resistance furnace is solved. According to the technical scheme, anti-skid protrusions are arranged on the outer side wall, close to a hearth, of a furnace door; anti-skid grooves corresponding to the anti-skid bulges are formed in the inner side wall of the hearth; the anti-skid groove is far away from one end of the bottom wall of the hearth; a heat insulation plate is arranged between the hearth and the furnace door and detachably connected to the inner side wall of the hearth, heat in thehearth is prevented from flowing into external air through a gap between the furnace door and the hearth, and therefore the purposes of improving the heat preservation performance of the box-type resistance furnace and reduci |
