Low creep fire clay brick for hot-blast stove

impact resistant performance is good Resistance to temperature creep good performance

1.Uses the high quality clay clinker, the high-pressure forming, the high temperature burn becomes

2.characterized by HRUL,resistance to temperature creep good performance

3.Is the hot blast stove in the low temperature site with the use of main refractory

4.Physical and chemical indexes
