Burning loss resistant torpedo ladle cover and preparation method thereof
A torpedo ladle cover resistant to burning loss comprises a half torpedo ladle cover body composed of a metal shell, lifting lugs, a fiber heat preservation layer and anchoring parts, a wear-resisting castable baffle is poured on the edge of the metal shell, the fiber heat preservation layer connected with the inner wall of the metal shell is left outside the wear-resisting castable baffle, and a protection castable layer is poured on the fiber heat preservation layer. The other half part of the torpedo ladle cover has the same structure; the preparation method comprises the following steps: firstly, welding the anchoring part on the inner wall of the metal shell, then supporting a template according to a set wear-resistant castable gear thickness, and finally pouring the wear-resistant castable; carrying out gear hardening on the formed wear-resistant castable; fixedly connecting the fiber thermal insulation layer; a protective castable layer is poured after the die is supported in the range of the protective castable layer to be poured; drying after demolding; performing baking; and naturally cooling to room temperature for later use. According to the invention, the replacement period of the tank cover is prolonged from about 1 month to not less than 6 months, the cost is correspondingly reduced by at least 30%, and the method is easy to implement.
一种耐烧损的鱼雷罐罐盖，由金属外壳，吊耳、纤维保温层、锚固件组成的鱼雷罐罐盖半边，其在金属外壳的沿边上浇筑有耐磨浇注料档，在耐磨浇注料档外剩余金属外壳的内壁连接的纤维保温层、在纤维保温层上浇筑的保护浇注料层；鱼雷罐罐盖另半边的结构与上述相同；制备方法：先将锚固件焊接在金属外壳内壁上，后按设定的耐磨浇注料档厚度支护模板，最后浇注耐磨浇注料；对形成耐磨浇注料档硬化；固定连接纤维保温层；在要浇筑的保护浇注料层范围支护模具后浇注保护浇注料层；脱模后干燥；烘烤；自然冷却至室温后备用。本发明使罐盖更换周期由现有的1个月左右提高至不低于6个月，成本相应降低至少30％，且易实施。
