The invention relates to a mould for a tundish permanent layer, the permanent layer and a manufacturing method of the permanent layer. The mould for the tundish permanent layer comprises a mould body and angle steel, wherein the angle steel is uniformly arranged on the side surface of the mould body; the upper edge of the angle steel is flush with the upper edge of the mould body; and the axis of the angle steel is vertical to the upper edge of the mould body. According to the mould for the tundish permanent layer, the permanent layer with a fixed groove in the surface can be obtained through pouring, the binding force between the permanent layer and a working layer is improved, the problem that the working layer is separated from the permanent layer in the service cycle of the working layer is avoided, and stable and smooth production is ensured. 本发明涉及一种中间包永久层用胎具、永久层及其制造方法，所述中间包永久层用胎具包括胎体和角钢；所述角钢均匀设置于所述胎体的侧表面；所述角钢的上沿与所述胎体的上沿平齐；所述角钢的轴线与所述胎体的上沿垂直。本发明提供的中间包永久层用胎具可以浇注得到表面具有固定凹槽的永久层，提升了与工作层之间的结合力，避免了在工作层的使用周期内发生工
