Abstract
The utility model belongs to the technical field of iron and steel smelting equipment and relates to a slow cooling device for electrically heated steel. The slow cooling device comprises a furnace body and a furnace cover. The furnace body is provided with a flame retardant coating, an electric heating layer, and an insulating layer which are sequentially arranged from inside to outside. The furnace cover is provided with a heat emission hole. A temperature sensor is disposed in the furnace body, the electric heating layer is connected with a power supply through a relay, and the cooling device also comprises a gland. The slow cooling device has the advantages of postponing heat loss in the furnace body through the insulation of the insulating layer, avoiding influence on steel quality caused when temperature drops too quickly in the slow cooling process by utilizing the electric layer to adjust the temperature in the furnace body, and preventing phase change structural stress and thermal stress so as to avoid cracks in steel materials by the adoption of the gland.
