Chemical Packing >>> Ceramic Ball
>>>
Thermal
Storage Ball
Series
of ceramic balls have been developed since 1972, applying in various
industries, e.g. chemical, petrochemical, fertilizer, fine chemicals
and environmental protection industries. Several patents of our
products or production were granted by national authorities.

Thermal Storage Ball |
|
With the smooth surface,
thermal storage ball owns the characters of
high mechanical strength, high abrasion resistance, high thermal
conductivity & thermal capacity, high thermal stability, and excellent heat
endurance.
There are three
types, including ceramic ball, porous ceramic column and porous ceramic ball.
It's specially applied as thermal storage packing in heat
accumulator of air separation equipments, heating stove of blast
furnace gas in the steel industry.
During the process of
steel rolling, if thermal storage
ball is installed, it can preheat both air and gas so as to ensure
burning temperature achieve the requirement quickly required by heating of
billet during steel rolling.
