Non-standard Copper Mould Tube
Square, Rectangular, Round and Beam Blank copper mould tubes. With dedicated to research of new technologies, we continuously develop various sizes, materials and special shapes, large and super large size mould tubes.
The most critical area in continuous casting is where the liquid steel turns into solid form. This is where the mould and related technologies come into existence to achieve successful and high-quality castings. LMM GROUP with decades of experience in moulds and surrounding technologies, will direct you to the best solutions for success.
