The invention provides a wave-type mud cylinder lining used for a brick and tile extruder. The wave-type mud cylinder lining is provided with a lining body. The outer surface and the inner surface of the lining body both are cylindrical. A plurality of lining strips are evenly arranged on the inner surface of the lining body in the axial direction. The lining strips are in wave-type shapes. It is favorable for the brick and tile extruder to extrude and form relative high-plasticity mud strips, the technical problem that in the prior art, extruding forming is difficult, or the product is bad in quality is solved, and the working efficiency of the extruder is improved.
