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.

Q6.What are the payment terms?

Usually T/T,but L/C,Western Union etc are available for us.

Q7. How long is delivery time?

The delivery time will be determined according to the quantity of the order.

Q8.How are your products’ quality?

The products will be strictly inspected before shipment, so the quality could be guaranteed.

Q9.How to slove the quality problems?

A:If the products are not confirmed to customer samples or have quality problems,our compay will be responsible to make compensation for it.

Q10.What is the service life of your bricks?

A:The service life of different bricks is unlike.It also depends on your using condition and method.

Q11.How about your company's certification?

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

Q:How to test the aluminium bricks of high alumina refractory bricks?: Forming high alumina brick will be tested on some professional equipment, it is suggested that you can go to the professional testing department to know about it!

Q:How to distinguish the good or bad of the high aluminum brick?: Weigh the weight of the next block. According to the weight standard, a high alumina brick is 3.9 kg in weight, two in high alumina brick, three in high aluminium brick and 4.5 kg in 4.2. The same grade, the same type of high alumina brick, if the weight of a single brick to this standard, but for high quality high alumina brick, otherwise, can not reach such a weight, it shows good quality. If there is a crack, a large piece of broken angle, four sides of inequality, it is for substandard products.

Q:Difference between low creep high alumina brick and ordinary high alumina brick: Low creep and high alumina brick is based on the theory of "three stones". The combination of bauxite and clay as the main raw material, adding kyanite, andalusite and sillimanite, commonly known as the "three stone" control, physicochemical index and size composition, using alumina mullite corundum + + raw materials such as technical scheme. In the production process, first to detect and control indexes of raw materials, crushing, grinding, sieving process, according to the distribution ratio of ingredients, the size and moisture control of mud mixing after to meet the requirements of forming and molding machine, the use of qualified abrasives, blow molding control number, size and flash at the same time, the detection efficiency of semi-finished products and meet the requirements. Production process: high temperature calcination of high-grade alumina, adding small creep rate of high temperature materials, by high-pressure molding and high temperature firing. It has the characteristics of high strength, low creep rate and high use temperature. Widely used in high temperature furnace, hot air furnace hearth lining, brick and so on.

Q:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?: The super high alumina brick in high alumina refractory brick has the highest refractoriness, and the corresponding production cost is higher.

Q:The difference between ordinary and diatomite brick refractory brick: Insulation products made from diatomaceous brick and porous diatomite. The main raw material is natural porous diatomite, and then a small amount of clay and fuel are added. The volume density of diatomite brick was 0.7g/cm3, compressive strength at room temperature is 1 ~ 2MPa, the coefficient of thermal conductivity at 400 C for 0.13 ~ 0.20W/ (M - K), the apparent porosity is greater than 70%, the coefficient of thermal expansion (1280 degrees) 0.9 x 10 - 6 DEG -1, refractoriness is greater than 1250 DEG C. Mainly used in industrial kilns and other thermal equipment, thermal pipes insulation materials, generally withstand the hot surface temperature of about 1000 degrees celsius. Mainly used in industrial kilns and other thermal equipment, thermal pipes insulation materials, generally withstand the hot surface temperature of about 1000 degrees celsius.

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:How much is one ton of high alumina refractory brick?: Three high aluminum refractory brick Zhengzhou Kuwait is generally around 800. 32 years of experience, good.

Q:What are the reasons for the spalling of refractory bricks in the production of lime kiln?: In the course of the production of lime kiln, the local block of refractory brick is a very dangerous signal. It is suggested that you stop the kiln to prevent the collapse of a large area. Lime kiln is the main equipment for the production of limestone kiln and rotary kiln is two, with the growth of calcium carbide lime kiln industry, iron and steel industry, the construction industry to the amount of limestone has become the main production equipment, and refractory bricks became the heart of lime kiln.

Q:Does the chimney have high acid resistance?: The acid resistant bricks used for chimney are usually made of custom-made trapezoidal acid proof bricks, and the physical and chemical indexes of acid resistant bricks need to be confirmed according to the chimney's actual emission. At this point, you can consult our kerei refractories.

Q:How many cubic bricks does a high alumina brick have?: Different content of aluminum, different proportion, weight is not the same. General grade T3 standard brick, 4.3~4.5kg, aluminium content 75. T3 size 230*114*65mm.
