Chrome series refractory bricks are made by isostatic pressing production technology, with properties of high resistance to glass liquid erosion, excellent thermal shock resistance, and high service lifetime and are mainly used in the serious erosion parts of fiberglass kilns: such as tank walls, throat, bottom pavings, near bubbler, doghouse, corners, forehearth, flow blocks, etc.
