Dense Chromium Oxide Bricks

Manufacturing method: Isostatic pressing

Features:

  1. Strong resistance to glass liquid erosion
  2. Excellent thermal shock resistance
  3. high service lifetime

Applications:

Fiberglass( E-glass ) furnace, such as Tank wall, throat, bottom pavings, near bubblers, doghouse, corners, forehearth, flow blocks, etc

Items:

  1. Dense Chromium Oxide Bricks
  2. Grain Chromium Oxide Bricks
  3. Chrome-Alumina-Zircon Bricks

Category:

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.
