Its refractoriness is 1580-1750℃, refractoriness under load is 1250-1450 ℃, line expansion coefficients is low, with good thermal shock resistance and strong ability to resist erosion acid slag. Features&advantages sk34 refractory brick Feature: Low thermal conductivity Excellent acid and base slagging resistance High refractoriness Excellent thermal shock resistance Excellent mechanical strength sk34 refractory brick Advantages: 1. High resistance to thermal shock, abrasion, chemical attack to provide long service life; 2. High dense structure; 3. Low permanent linear change on reheating; 4. Easy operation and installation; 5. Broad usage or applications and low price, etc. Index Item N-1 N-2a N-2b N-3a N-3b N-4 N-5 N-6 Refractoriness, CN 176 174 174 172 172 170 166 158 Refractoriness under load ,℃ 2kg/cm2≥ 1400 1350 1320 1300 Reheating linear change% 1400℃,2h +0.1-0.4 +0.1-0.5 +0.2-0.5 1350℃,2h +0.2-0.5 +0.2-0.5 +0.2-0.5 +0.2-0.5 Apparent porosity,%≤ 22 24 26 24 26 24 26 28 Compress strength,N/mm2≥ 30 25 20 20 15 20 15 15 Thermal shockresistance N-2b, N-3b must be tested and list the actual measuring data in the quality Certification. sk34 refractory brick are mainly used in the low temperature parts of blast furnaces, waste incinerators and glass melting furnaces. Due to the scale-up of a variety of industrial furnaces and severity of operating conditions, super dense clay bricks that made of more refined chamotte being calcinated at high temperature are applied more than before. It's popular in the following furnaces:1. Blast furnaces and hot blast furnaces2. Waste incinerators3. Glass melting furnaces What is the Shapes &Sizes of our fireclay brick?

FAQ Q1.What is the difference between Refractoriness and Working temperature ? A1:Refractoriness:the refractory material withstands high temperature without melting and softening performance in the absence of load resistance. Q2.How are the products’ quality? A2:The products will be strictly inspected before shipment, so the quality could be guaranteed. Q3:What is the Warranty for the fire brick? A3:For all the brick,we have 1 years warranty.If any quality problems on our side occured in this period ,we will take on the shipping cost and replacement. Q4.What is the service life of the bricks? A4:The service life of different bricks is unlike.It also depends on your using condition and method. Q5:Are you a manufacture or trader? A5:To be honest we are a trader,but we have stable cooperation factories.And we can supply good pre-sale service, after-sales service.
