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.

Q11.How about your company's certification?

A:ISO9001 and Test Report,also we could apply other necessary certification.

Q: What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?: All the raw materials adding order, mixing time, material and material moisture trapped. 4, the pressure and the volume density of Pei brick and brick Pei size etc..

Q: The difference between aluminium refractory and magnesia refractory: Aluminum refractory belongs to neutral refractory material, usually refers to silicon aluminum refractory materials, such as: high alumina brick, clay brick, high alumina castable and other products, the production of raw materials is mainly bauxite.

Q: The cloth blowing is not uniform on the lime kiln refractory brick is damaged it: People with the shaft kiln cement clinker kiln, because of small size, low calcination temperature, using only Al2O3 containing a single clay brick is 30 ~ 40%, the rotary kiln was improved in the early Yuan faith this experience, use of high alumina brick and clay brick, from 60s onwards, due to large scale kiln and to strengthen the operation of the high temperature parts of kiln lining, alkaline brick masonry is widely used, the main varieties are: magnesia chrome brick, magnesia spinel brick and dolomite brick.

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: Which is faster for heat transfer between corundum bricks and high alumina bricks?: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.

Q: Can high alumina brick resist carburizing?: It is heavy brick mullite brick, brick to do the heavy weight to more than 2.4 manufacturers can achieve a few feeling

Q: How much is one ton / ton of high alumina refractory brick?: The price of high alumina refractory bricks is not equal, according to the quality index of GB2988-2012

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: What is the difference between fireclay bricks and high alumina refractory bricks?: High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3.

Q: What are the lining structures of lime rotary kilns and what are the requirements for refractories?: The current configuration of domestic calcining active lime rotary kiln refractories are as follows: the discharge end of low cement high alumina castable with 3% steel fiber; the cooling zone and the firing zone: dry magnesia spinel brick with high aluminum brick with high temperature; preheating: high alumina brick; low temperature preheating zone: clay brick light clay brick; feeding end: low cement high alumina castable with 3% steel fiber; in addition, brick size also have the corresponding requirements; dimensional tolerances: dimensional tolerances used in different parts of the requirements are not the same, the general control in 2mm; corner damage: general permit edge damage 40mm and 5mm deep within angle loss in the hot and cold surface is allowed to have only one, three edges and the length of not more than 50mm; there are cracks parallel to the use of surface crack is not allowed, cracks of brick surface are allowed.
