Titanium cast ingot, method for obtaining titanium cast ingot and method for directly rolling cast ingot into square billet

The invention belongs to the technical field of hot working, and particularly relates to a titanium cast ingot, a method for obtaining the titanium cast ingot and a method for directly rolling the cast ingot into a square billet. The titanium cast ingot comprises a titanium cast ingot body and a titanium compensation block, the titanium compensation block is arranged on the end face of the titanium cast ingot body. According to the titanium cast ingot, the compensation block is arranged on the titanium cast ingot body, the compensation block inhibits inward shrinkage of the middle of the titanium cast ingot body in the rolling process, end face metal flowing is improved, folding is greatly reduced, the loss of the titanium cast ingot is reduced, and the yield is increased. 本发明属于热加工技术领域，具体涉及一种钛铸锭、获得钛铸锭的方法及铸锭直轧方坯的方法。其中一种钛铸锭，包括：钛铸锭本体和钛补偿块；所述钛铸锭本体的端面设置有一个所述钛补偿块。本发明的一种钛铸锭由于在钛铸锭本体上设置了补偿块，补偿块抑制了轧制过程中钛铸锭本体中部的内缩，改善了端面金属流动，大幅降低了折叠，减少了钛铸锭的损失，提高了成材率。
