What is the details of our refractory porous brick?
1.Made by bauxite clinker and binder through Crushing,Mixing,Shaping,Drying and high temperature Sintering.
2.Al2O3 content is 55%-80%.
3.Main mineral components are corundum and mullite phases.
4.Refractoriness is usually above 1770°C,refractoriness under load is 1420-1550°C.It is a neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion.
5.Working temperature:1350°C -1650°C.

Dengda Electric Melting Charging Co., Ltd is committed to high quality standards for all products and services. With its thirst on State of the art technology at every level and a wide range of products, we could provide ideal solutions for the stringent requirement of the customer. Backed by decade of experience in different industries, and close association with customers, Dengda will always bring new products which will give better life and value to the user.
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.
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: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.
Q6.Can we visit your company?
A6:Sure,welcome at any time,seeing is believing.
Q7. Do you provide samples?
A7:Yes, samples are available.

A8:Yes, we can do OEM.
Q9.What's the MOQ of trial order?
A9:No limit,We can offer the best suggestions and solutions according to your condition.
Q10.What are the payment terms?
A10:Usually T/T,but L/C,Western Union etc are available for us.
Q11. How long is delivery time?
A11:The delivery time will be determined according to the quantity of the order.
Q12.How about your company's certification?
A12:ISO9001 and Test Report,also we could apply other necessary certification.
Q13:Can we get support if we have our own market position?
A13:Please inform us your detailed mind on your market demand,we will discuss and propose helpful suggestion for you,to find the best solution for you.
