Abstract
Apparatus and related method for taking a sample of molten metal from a vessel comprising a refractory block installed in a wall of the vessel before the vessel is filled with molten metal. The block is traversed by at least one passage having a closure element to initially block the passage. A rigid elongated pipe is movable lengthwise in the passage and a sample mould is operatively associated with the pipe. There is means activatable to advance the pipe forcibly in a forward direction to cause a forward end of the pipe to engage the closure element for unblocking the passage whereby molten metal gains access to the pipe and flows along the pipe to enter the mould.
