The invention relates to transport equipment of a hot continuous rolling metal head, and in particular relates to a metal-head box of a hot continuous rolling production line. The metal-head box of the hot continuous rolling production line comprises a box body, wherein suspension beam arms are fixedly arranged on the left surface and the right surface of the box body; the top ends of the suspension beam arms are arranged above the upper top surface of the box body; the suspension beam arms are composed of two suspension beams of which the top ends are fixedly connected with each other, and a certain included angle is arranged between the two suspension beams; the other ends of the suspension beams are fixed to the box body; the top ends of the two suspension beam arms are fixedly connected with each other through a cross beam; a hoisting hole is formed in the cross beam; the front surface of the box body is obliquely arranged relative to the bottom surface, and the upper top surface is longer than the lower bottom surface. The metal-head box of the hot continuous rolling production line has the advantages of being easily loaded and unloaded, and reliable to use.
