Test furnace for testing thermal shock resistance of carbon-containing refractory material

The utility model discloses a test furnace for testing thermal shock resistance of a carbon-containing refractory material, which comprises a furnace body, a furnace lining is arranged in the furnace body, a cooling chamber and a heating chamber are arranged in the furnace lining, and a liftable partition plate for communicating and separating the cooling chamber and the heating chamber is arranged between the cooling chamber and the heating chamber. The carbon-containing refractory material rapid cooling device is simple in design structure and convenient to use, a sample is rapidly heated under the condition of air isolation, the sample is rapidly cooled through inert gas N2, the situation that carbon in a carbon-containing refractory material is lost at the high temperature is effectively avoided, and the carbon-containing refractory material rapid cooling device is suitable for large-scale production. N2 is uniformly blown to the surface of the sample at a fixed position in the cooling chamber, so that th
