FAQ

Q1: How do you control the products quality?

A1: With strict quality control system throughout the materials selection and production process, our refractory and ceramic fiber products quality is effectively controlled to meet customer requirements.

From the raw materials selecting, our quality control begin. The quality certificates of raw materials are required and each batch will be tested before using. During production, the quality control are conducted by workers and then each piece will be sorted and examined by quality supervis

 

Q2: What`s the lead time for my order?

A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks,10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.

 

Q3: Can you offer Door-to-Door delivery?

A3: Yes, but only for some countries such us U.S., UAE, Saudi Arabia, Iran, and Russia, etc.

Q:What refractory materials are adopted in each part of the blast furnace
The furnace throat is a part of the direct impact and friction when the burden drops, and the high density and high alumina brick is usually adopted. The upper and middle shaft temperature is only 400~800 degrees, the parts with high alumina brick and sillimanite brick.
Q:What's the size of the fused zirconia corundum refractories for glass furnace? What are the main kilns? How much is the dosage?
The fused zirconia corundum brick is made up of 30% ~ 41% zirconia two in the alumina burden. The main mineral compositions are corundum, zircon and glass phase. The main varieties are fused (or cast) zirconium corundum brick (also known as AZS casting brick) and sintered zirconia corundum brick. Generally speaking, zircon corundum brick means sintered zirconia corundum brick. It is made from alpha -Al2O3, partially stabilized zirconia and zircon corundum clinker, which is prepared by proportioning and molding at 1700~1750 DEG C and then sintered at two. The sintered zirconium corundum brick has a strong resistance to molten glass, and its thermal shock resistance is stronger than that of fused zirconia corundum brick. It is mainly used as lining of glass furnace and induction furnace, as well as steel rolling furnace, slide rail, etc..
Q:What is the blast furnace ceramic cup called by the refractory factory?
In fact, a kind of ceramic cup of blast furnace refractories, application in blast furnace bottom and hearth contact steel lining using a layer of non carbon refractory materials, such as Theron with corundum brick, corundum mullite and synthetic mullite bricks etc..
Q:Can the PE sintering plate dust collector be suitable for dust removal in the coking plant?
The sinter plate dust collector is also called plastic plate dust collector. The utility model has the advantages that the utility model can adapt to various complicated working conditions, the dust removal rate is 99.99%, the utility model has the advantages of long service life, stable operation, high temperature resistance, and the utility model is a leading dedusting equipment in china.
Q:How much is a thermal brick?
Insulation brick prices also have a great relationship with the material and workmanship, such as clay brick price is much lower than high alumina brick, mullite and corundum brick prices will be higher.
Q:Can the fire clay be reused?
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.
Q:What kind of fused corundum corundum brick should be used for each part of the glass furnace?
The compact microstructure of AZS33# zirconia corundum brick makes the bricks resistant to glass liquid corrosion, and it is difficult to produce stone or other defects in the glass kiln. It is the most widely used product in the glass furnace. It is mainly applied to the upper structure of the melting pool, the wall brick of the working pool and the paving brick, the material way, etc..
Q:Which is faster for heat transfer between corundum bricks and high alumina bricks
There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color.
Q:What is the hardness of corundum refractory bricks?
Corundum refractory brick has good stability against acid and alkaline slag, metal and glass solution. It can be used in oxidizing atmosphere at high temperature or in a reductive atmosphere. The basic material of corundum refractory brick is fused alumina or sintered corundum.
Q:What is the standard classification of high alumina bricks and high alumina bricks?
Refractory brick is non-metallic materials can be classified according to a kind of inorganic material, high aluminum brick, clay brick, magnesia brick, corundum brick, mullite bricks, silicon carbide materials such as brick, high alumina brick is used as a relatively wide range of products in accordance with the refractory brick high alumina refractory materials by high aluminum brick is generally divided into Al2O3 content three: I - II - >75% Al2O3 content; the content of Al2O3 is 60 ~ 75%; III - Al2O3 content from 48 to 60%.
