Abstract
The utility model relates to a pipe-type water cooling device for a furnace lining at the top of an integral casting furnace. The water cooling device is provided with a water cooling pipe in which cooling water can flow and an outer sleeve pipe which is wrapped outside the water cooling pipe, wherein the water cooling pipe and the outer sleeve pipe are buried in the fire-resistant furnace lining at the top of the integral casting furnace; when the water cooling pipe is expanded in a heating manner, the water cooling pipe can slidably extend along the outer sleeve pipe due to the setting of the sizes of the outer diameter of the water cooling pipe and the inner diameter of the outer sleeve pipe; two ends of the water cooling pipe extend out of the fire-resistant furnace lining. When the water cooling pipe is expanded in the heating manner or is cooled due to the furnace shutdown, the water cooling pipe can freely extend or contract to two ends along the axial direction of the outer sleeve pipe, so that the squeezing force and the fixing force which are borne by the cooling pipe during an operation because the expansion rate of the cooling pipe is inconsistent with that of the fire-resistant furnace lining are avoided. Thus, the application safety of the water cooling pipe is ensured; the cooling water is prevented from being leaked, i.e., the potential safety hazard of water leakage in the furnace is solved. The water cooling device is simple in material source, simple to manufacture, low in manufacturing cost, high in cooling efficiency and suitable for various types of furnaces.
