Zircon Ramming Mix
Zircon Ramming Mix/Strong resistance to glass liquid erosion
ability/Weak tendency to precipitate bubbles
Summary:
Adopting high quality zircon and AZS powder as raw material,
processed through special process, the zircon ramming mix is
characterized with high resistance to glass liquid erosion, lower
air bubble defects etc., and is the ideal monolithic refractories
for seal of glass tank bottom, filling of wall space and hot
repairing etc.
Product features:
- 1.Strong resistance to glass liquid erosion ability
- 2. Weak tendency to precipitate bubbles
Range of application:
Suitable for cold repair of AC electric furnace bottom, furnace
slope, and DC electric furnace slope.

Construction method:
- Refractory Ramming Mass are generally compacted using pneumatic
picks. When using a pneumatic pick to compact, the wind pressure
should not be lower than 5 atmospheres; The hammer head has various
shapes such as square, rectangle, and circle, with a general size
between 50-80 millimeters. If it is too large, the compaction force
is insufficient, the compactness is poor, and it affects the
performance of refractory compaction materials; If it is too small,
the pounding force will be too strong, making it difficult to
compact and affecting work efficiency.
- When pounding, the thickness of the material should be 20-60
millimeters each time. The air pick should be perpendicular to the
material surface, and the hammer head should move continuously in
one direction. The hammer heads should overlap by one-third to
one-half to avoid leakage, and each row should also overlap. After
each layer of material is continuously pounded four or five times
to achieve uniform density and form a whole, the next layer of
material can be laid.
- The compaction construction should be carried out continuously. If
the interruption time is long, the compaction surface should be
covered tightly. During further construction, the tamping surface
should be roughened before proceeding with tamping.
- After pounding, the mold can be immediately removed for maintenance
or baking.
