The invention provides a sintering furnace for aluminum oxide ceramic production, and belongs to the technical field of sintering furnaces. The sintering furnace comprises a bottom base, a fixing plate, a fan and an air inlet pipe, wherein the fixing plate is located on one side of the bottom base and fixedly connected with the bottom base, the fan is arranged on the right side of the bottom base, the air inlet pipe is arranged on one side of the fan, the air inlet pipe is in through connection with the fan, a boiler base is arranged at the upper end of the bottom base, and the boiler base is fixedly connected with the bottom base. According to the sintering furnace for the aluminum oxide ceramic production, through structural improvement, when the sintering furnace is actually used, by arranging a temperature sensor and a temperature displayer, the external personnel can effectively observe an internal temperature condition and can make emergency treatment in time, an internal temperature is prevented from reaching a critical value, by arranging a cooling water pipe, when the interior of the sintering furnace for the aluminum oxide ceramic production breaks down, a furnace body can be cooled by means of the cooling water pipe, a furnace explosion phenomenon is avoided, and practicability is high.
