Tin column casting line

The utility model discloses a tin column casting line comprising an alloy holding furnace, a casting hole braking pin, a tin column forming module, a cooling water tank, a pull cylinder, a pull wheel set, a fixed tin column cylinder, a saw, a proximity switch support wheel, a discharge device cylinder, a tin cylinder discharge tray, a tin column positioning plug pin, a feed rack and a feed rack fixing block. A continuous casting pipeline is arranged at the bottom of the alloy holding furnace and communicated with the tin column forming module. The cooling water tank is arranged on the outside of the middle of the continuous casting pipeline. Circulating cooling water circulates in the cooling water tank. Continuous tin columns are pulled by the pull cylinder and the pull wheel set which are arranged on a pull device and are further positioned by the aid of the fixed tin column cylinder and the proximity switch support wheel and are cut by the saw, and accordingly finished tin columns are achieved. According to the arrangement, the automatically-discharging manner is adopted, scald is prevented, labor cost is lowered, and production efficiency is increased; due to the feed rack provided with multiple layers, available plant space is expanded.
