摘要（英）：

The invention discloses a heat shield structure of a heat treatment trolley. The heat shield structure comprises a furnace door and a winch. A heat shield is arranged in front of the winch, and fixedto the top of the trolley through bolts. The heat shield is rectangular, is erected in front of the winch and is composed of two flame retardant layers and three thermal insulating layers. The heightof the heat shield is larger than that of the winch. The two flame retardant layers are made of high aluminum carpets. The three thermal insulating layers are made of 1140 carpets. By adopting the technical scheme, the heat shield is additionally arranged between the furnace door and the winch and does not need to be replaced frequently, the production cost is lowered, and accordingly, the servicelife is prolonged.
