The invention provides a roasting furnace cover and a manufacturing method thereof. The roasting furnace cover is formed by an integral ceramic fiber module by processing, and the volume weight of thefurnace cover is 0.2-0.26 g/cm . The furnace cover provided by the invention is low in weight and easy to remove and carry; meanwhile, the furnace cover has high high-temperature intensity, low heat conductivity coefficient and collision resistance under high temperature, is not prone to being damaged, long in service life, remarkable in heat preservation and heat insulation effects, needs no extra sealing material during use, and can effectively reduce the running energy consumption of a roasting furnace. The roasting furnace cover is obtained by the steps of melting, fiber forming, cottoncollection, roller puncture, cutting and calcining on ceramic fiber raw materials. In the process of manufacturing the furnace cover with the method, no built-in handle or mold is needed, furnace covers in any shape and of prec
