A horizontal pyrolysis furnace has a kiln and two barrels. The two barrels are respectively a processing barrel rotatably disposed in the kiln and a takeover barrel detachably connected with the processing barrel. Each one of the two barrels has a gate assembly and at least one spiral guiding plate. The gate assembly of the processing barrel is mounted on an end of the processing barrel, and extends out from the kiln. The two gate assemblies of the two barrels are detachably connected such that the two barrels are able to rotate synchronously. The at least one spiral guiding plate is fixed on an inner surface of one of the two barrels, and the spiral guiding plates of both barrels have an identical helical direction.

The object of the present invention is to improve production efficiency of lithium hydroxide anhydride in a method for producing lithium hydroxide anhydride from lithium hydroxide hydrate by using a rotary kiln. The method for producing lithium hydroxide anhydride comprises steps of: supplying the lithium hydroxide hydrate to a region between a heating part which is the part of the furnace core tube surrounded by the heating furnace and one end of the furnace core tube; delivering the supplied lithium hydroxide hydrate toward the other end of the furnace core tube; feeding a drying gas with a temperature of 100° C. or higher to the region between the one end and the heating part of the furnace core tube, when the lithium hydroxide hydrate is supplied; and heating and dehydrating the lithium hydroxide hydrate by the heating furnace which is set to 230-450° C. during the lithium hydroxide delivering step, to form lithium hydroxide anhydride.
