Impact-resistant heat-insulation kiln lining device of double-hearth kiln and preparation method

The embodiment of the invention provides an impact-resistant heat-insulation kiln lining device of a double-hearth kiln and a preparation method, and relates to the field of kiln linings of double-hearth kilns. The problem that a blanking position kiln lining is not resistant to impact is solved. The impact-resistant heat-insulation kiln lining device of the double-hearth kiln comprises a kiln shell, a cavity protection steel plate, a bottom plate and castable, the cavity protection steel plate is arranged in the kiln shell and surrounds the kiln shell by a circle in the circumferential direction of the kiln shell. The bottom plate is connected and fixed with the cavity protection steel plate and the side wall of the kiln shell, so that a pouring cavity is formed between the cavity protection steel plate and the kiln shell; and the pouring material is poured and filled in the pouring cavity. The device is manufactured through the manufacturing method of the impact-resistant heat-insulation kiln lining of the
