          1. QCB series strong magnetic bar

            QCB series strong magnetic bar high-performance rare earth neodymium by sophisticated magnetic circuit design, the surface magnetic field of up to 8000-14000GS. The principle is: when iron substances through by the attractiveness of a strong magnetic field, the iron-containing substances are strongly adsorbed on the tube wall to ensure the integrity of equipment and the safety of the product, can greatly reduce the iron content in the finished material amount.
