Refractory castable is a mixture which is calcium aluminate cement as binder,and with a range of particle size distribution of refractory aggregate and admixture.
1.Binder -- There are two kinds of calcium aluminate cement as binder
a.general calcium aluminate cement:made by high alumina bauxite and limestone materials
b.high pure calcium aluminate cement:made by industrial alumina and limestone
a.fire clay (chamotte)
c.mullite and corundum
What is the Feature of Our castable refractory cement for furnace?
1.Easy to operate: times and labor saving, shorten the work time, reduce work strength of workers.
a.high mechanical strength,
b.good thermal shock resistance,
c.tiny linear variation,no cracking,
d.resistant to scour and erosion,
e.good abrasion resistant,
f. good volume stability under high temperature.
3.Extend service life: high technical content, good property in using.
