Specific construction scheme:
▶ Clean the dust and rust on the surface, brush the severely rusted parts with anti- corrosive coating, spray SNTG -200 aerogel coating twice until the thickness reaches 3mm, and then spray SNTG-100 aerogel coating twice after drying until the thickness reaches 1mm.

Conclusion:
▶ After construction, the surface temperature of cracking furnace is 48 ℃, which has obvious energy- saving effect and does not affect normal production and convenient construction.
