Construction method for refractory castables on furnace roofs
Thread Content
Which construction method is better for furnace roof refractory castables (manual ramming, formwork casting, mechanical spraying, etc.)? What are the advantages and disadvantages of each?
Generally, hand-pressed ones are more commonly used
It is safer to start with manual ramming and formwork placement followed by pouring
Generally, formwork is set up first, followed by the preparation of fire-resistant concrete, and finally pouring takes place
It depends on how large the span is, I guess? For large spans, a forced mixer is required for mixing, followed by formwork placement and pouring; in addition, suspension fixtures must be installed for hanging.
