Product Details

$Melt-Extracting Stainless Steel Fibre with Refractory Materials$ Stainless Steel Fibre (SSF)

The performance of SSF

After mixing SSF with refractory matrix, all of the properties of anti- fire structures, such as resistance to damage from thermal shock cycling, impact resistance, anti – fire gradient, anti – friction and abrasion resistance may be improved and the durability of materials can be elongated.
Mixing SSF with refractory will be able to reduce maintenance costs and energy consumption by a big margin. Production- stop accidents due to break- down of refractory materials can also be reduced greatly. Equipments may be used effectively, production may be kept in continuity and the products costs will be lowered. Therefore, an out-standing economic effect is gained.
If SSF would have been mixed with refractory matrix , it will be protected and reduced from cracking and abrasion under high- temperature condition, improving flexural strength as well as splat cooling and heating capabilities. Then also, there is a big increasing in thermal conductive coefficient.

SSF mixed proportion in refractory materials

The mixing ratio of SSF with refractory matrix is about 1-5% by weight.
