A hydrogen decrepitating furnace for shortening of feeding and discharging time capable of feeding and discharging materials easily comprises a main frame, a heating furnace, electric furnace stands and electric furnaces, wherein the heating furnace and a driving mechanism for driving the electric furnaces to rotate are arranged on the main frame, the heating furnace is provided with a feed and discharge port and a valve for opening or closing the feed and discharge port, a gas control device is connected to a side corresponding to the feed and discharge port of the heating furnace, the lifting mechanism is able to lift the heating furnace to allow materials to be easily discharged from the hydrogen decrepitation furnace, the electric furnaces are correspondingly arranged on the electric furnace stands, and moving mechanisms for driving the electric furnaces to be opened or closed are arranged on the two electric furnace stands.

Disclosed herein is a metallurgical furnace and roof having a drain system. The roof has a roof body comprising a top surface having a center opening, a bottom surface opposite the top surface, and an outer sidewall connecting the top surface to the bottom surface. The outer sidewall, the bottom surface and the top surface define an interior portion. An internal spray cooling system is disposed in the interior portion of the body. A drain system is integral with the body. The drain system has a roof evacuation conduit disposed outside the interior portion and configured to collect spay coolant from the interior portion of the body. The drain system additionally has a drain box having a vent and an exit pipe, wherein the roof evacuation conduit channels spent coolant by gravity into the drain box which is evacuated under gravity by the exit pipe.
