Ceramic fiber module or refractory brick for hot galvanizing furnace body insulation? Who gave me an analysis?
Tile blanket thickness 30mm, (2 layers of 20mm compression), hot surface layer, ceramic fiber module thickness of 300mm, total thickness of 330mm. The ceramic fiber module adopts a standard ceramic fiber module with a temperature range of 1260.Considering that the flame sprayed by the nozzle will rebound on the outer wall of the zinc pot and form a smoke wash between the furnace wall and the zinc pot wall, the wind speed is about 18m/s to 23m/s, and there is a certain corrosion. Ceramic fiber module surface brushing two times curing agent, that is resistant to corrosion, but also can resist high wind speed.
The arrangement mode of the ceramic fiber module adopts "soldier row type" - along the module compression size. Fiber module arrangement using ceramic fiber blanket folded thickness after 20mm compression, and the use of "U" type nail to keep the 500~700mm distance to the fiber module fixed to insert compensation fiber expansion surface may produce contraction, the structure can avoid the "parquet" arrangement, fiber module for the corner site the expansion caused by uneven phenomenon, "playboy" has the best effect of adiabatic. When the back lining of the furnace top is installed, the quick card matching module is used for temporary fixing with bolts.
After 2013, the hot dip galvanizing furnace is usually made of ceramic fiber modules for insulation, as follows:The appearance of new thermal insulation material breaks the inherent heat loss barrier in our country. The new type of thermal insulation material is mainly made of ceramic fiber and heat insulation cotton. It is combined with bolt, nut, carpet blanket, module and compensation blanket to achieve high heat preservation.
Hot galvanizing furnace is usually burning natural gas to the new pot heating, natural gas heating will produce higher wind speed to 21m/s, so the hot galvanized furnace insulation materials have certain requirements. The hot galvanizing furnace before 2013 is usually made of refractory bricks for heat preservation, and the energy saving effect is common.
