Castable refractory construction technology requirements:
Anchoring nails welded framework supporting, castable construction, casting, curing, and form removal.
(A) Anchoring nails welded
1 .Anchor nail materials and specifications must be in accordance with the design requirements of the procurement.
- Distribution and welding quality anchoring nails must be according to the design requirements.
(B) Framework supporting
- Accurate size, meet the design requirements.
- Support firm, tight seams ride, missed pulp.
- Corrosive or strong adhesion castable site isolation layer should be in the template.
- Reserved for expansion joints of wooden strips should be fixed firmly to prevent vibration during that shift.
- Before pouring, the template should be brushing release agent.
(C) Castable refractory construction
- Castable once stirred volume should be limited to less than 30min run.
- Castable should continuously pouring, pouring the first layer of material before the initial setting, the next layer should be finished pouring castable, if intermittent exceed its initial setting time of construction, construction joints should be required to deal with.
- When using plug-in vibrator, pouring layer thickness should not exceed 1.25 times the length of the vibrating rod action part, when using flat vibrator, its thickness should not exceed 200mm.
(D) Chaimo
- Does not load the template should be castable strength to ensure its surface and edges are not damaged due to release the case of form removal.
- Load a template; you should castable strength of more than 70%, before form removal.
