Production & Quality

1.Production Process

Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packing shipment


2.Quality Control

a.According to the chemical content,raw materials are classified into different levels to ensure quality of brick first.

b.During the production,every brick will be weighed twice strictly to reduce the error of weight .

c.Before delivery, the inspectors will inspect the size,appearance,physical and chemical properties of brick again in factory.

Q:What are the characteristics of high alumina bricks?
The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized high-temperature kilns and other energy consuming industries, such as chemical industry, electric power industry, etc.
Q:What are the alloy wear resistance materials?
KNMn19Cr2 (patent) high manganese alloy (ZGMn13Cr2MoRe), super high manganese alloy (ZGMn18Cr2MoRe); two: anti-wear chromium cast iron series: such as high, medium and low chromium alloy cast iron (Cr15MOZCu); three: wear resistant alloy steel series: such as, low and high carbon multi metal combined steel (such as ZG40SiMnCrMO and ZG35Cr2MoNiRe); four: ADI (ADI) series; five: all kinds of composite or gradient material and hard alloy materials, nano KN alloy (patent product): such as chromium carbide composite (Cr2C3+Q235), high-energy ion osmosized tungsten carbide materials (WCSP), high toughness of cemented carbide (YK25.6), KN999 nano alloy (Beijing Naimo patent) etc.;
Q:What is the heat preservation material used in a laboratory furnace?
Asbestos, high alumina brick, or carbonized silicon are often used.Thermal insulation materials are generally used to guide heat coefficient less than or equal to 0.2 of the material. Thermal insulation material development is very fast, and in industry and building the use of good insulation technology and materials, often can get twice the result with half the effort. Each ton of mineral cotton insulation used in the building saves one ton of oil a year.
Q:How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
The gas will directly lead the dome combustion, in order to ensure good mixing, complete combustion of gas and air in a short time, the combustion capacity of short flame or flameless combustion burner, commonly used for semi jet short flame burner.
Q:What refractory material does cupola lining use?
Materials defined as physical and chemical properties that allow them to be used in a high temperature environment are called refractory materials. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output.
Q:What is the density of a super high alumina brick and what is the price?
Of course, the transaction price, please choose refractory brick manufacturer is better.
Q:The difference between ordinary and diatomite brick refractory brick
Refractory brick belongs to a large class, according to different materials used are divided into: high alumina brick, dolomite brick, magnesia chrome brick, magnesia spinel brick, phosphate brick, carborundum brick, brick, mullite bricks etc..
Q:How are the grades of high alumina bricks differentiated?
High alumina brick: aluminium silicate refractory product with a content of three Al2O3 (two) and more than 48%
Q:The difference between aluminium refractory and magnesia refractory
Magnesia refractory belongs to alkaline refractory materials refers to refractory products such as magnesia magnesia brick magnesium iron spinel magnesium aluminum spinel magnesia ramming materials and other products of raw materials is the main crystal phase is periclase magnesia products
Q:What is the high temperature limit of refractory bricks and refractory soil?
According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, ordinary brick, specific rotation. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature.
