Universal arc high alumina brick clay brick
Products Description
Curved fire brick details
Made by flint clay clinker and binder,through Crushing,Mixing,Shaping,Drying and high temperature Sintering.
Al2O3 content is 30%-48%,SiO2 content is 50%-65%,and a small number of alkali metals,alkaline earthmetal oxides TiO2,Fe2O3 etc.
Mineral composition is usually mullite, quartz and glass phase.
Refractoriness is 1580-1750°C, refractoriness under load is 1250-1450°C, line expansion coefficients is low, with good thermal shock resistance,strong ability to resist erosion acid slag.
Working temperature:less than 1350°C.

Production & Quality
Production Process
Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packaging and Shipment
Quality Assurance
The quality assurance system consists of the following steps:
a.Inspection and Control of incoming raw materials:According to the chemical content,raw materials are classified into different levels to ensure quality of brick first.
b.Inspection and control of the process:During the production,every brick will be weighed twice strictly to reduce the error of weight .
c.Inspection of product Standardization of quality of each product by process control and experimentation.
d.Taking corrective measures whenever deviations are noted.
e.Quality audit by quality management.Before delivery, the inspectors will inspect the size,appearance,physical and chemical properties of brick again in factory.
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.Usually working temperature is less than refractoriness about 350-400°C.
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.Can we visit your company?
A5:Sure,welcome at any time,seeing is believing.
