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.

F&A

Q1.Are you a manufacture or trader?

A:To be honest we are a trader,but we have stable cooperation factories.And we can supply good pre-sale service, after-sales service.

Q2.Can we visit your company?

A:Sure,welcome at any time,seeing is believing.

Q3. Do you provide samples?

Yes, samples are available.

Q4. Do you accept OEM?

Yes, we can do OEM.

Q5.What's the MOQ of trial order?

A:No limit,We can offer the best suggestions and solutions according to your condition.

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 can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?: Top burning type hot blast stoveIt means that the burner is installed on the top of the hot blast furnace of the iron making equipment, and it does not need a special combustion chamber in the vault space. It is also called a non combustion chamber type hot blast stove.

Q:How are the high alumina bricks fired?: According to the quality requirements of different grades of high alumina brick, choose different grades of bauxite raw materials, it is conducive to rational use, fine materials, fine distribution, as far as possible not to use mixed grade severe raw materials. The quality of the clinker depends on the calcination temperature, calcination temperature, sintering temperature should be generally reached or slightly higher than that of alumina clinker sintering, to ensure the full and possible high volume density, and the two secondary Mullitization and sintering shrinkage effect in calcination process. Lightweight high alumina brick, also known as high aluminum insulation brick (high-aluminium heat insulating brick). A lightweight refractory consisting of mullite and glass phases or corundum in excess of 48%. The volume density is 0.4 ~ 1.35g/cm3. The porosity is 66% ~ 73%, and the compressive strength is 1 ~ 8MPa. Better thermal shock resistance.

Q:What materials are used for roof insulation?: The other one is inorganic insulation materials, such as Portland, rare earth insulation, the thickness should be 5 cm or more, up to the high cost of auxiliary materials of construction, to reinforce, new inorganic insulation material, the material thickness, on the line of 2-3 cm, direct smear on the top of the house, without auxiliary material, than the price of wool, high aluminum silicate cotton.

Q:What are ordinary bricks, refractory bricks, hollow bricks?: Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. 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, brick, brick and other specific type. 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. For example, refractory clay brick, high alumina brick, brick, brick etc..

Q:What's the difference between a well type annealing furnace and a box type annealing furnace?: 1. The shell of the furnace is welded by section steel and steel plate. 2, the furnace cover support adopts steel and guide rail combination mobile type. 3. The heating element is made of high resistance alloy 0Cr25Al5 produced by Beijing Shougang Group and arranged on the furnace side. 4, because the bottom bearing adopts high aluminum bricks, the circle center of the furnace set small, inside and outside heating. 5 、 furnace cover adopts hydraulic lifting, motor control, automatic walking. 6 、 temperature control system adopts PID SCR control, high accuracy.

Q:What refractory material does cupola lining use?: A class of inorganic nonmetallic materials with a refractoriness of not less than 1580 degrees. Refractoriness is defined as the temperature of a sample of a refractory cone sample that resists high temperature without loading and does not soften and melt down. But only in terms of fire resistance can not be fully described refractories, 1580 degrees of temperature is not absolute.

Q:The difference between clay bricks and clay bricks: Sintering bricks do not have clay bricks, so sintering bricks are made of stone. Clay brick is clay cooking, two yo, qualitative difference, but the appearance and color almost, but the quality is very different, life expectancy is also a great gap.

Q:What are the grades of high alumina bricks?: High alumina brick according to the aluminum content is generally divided into: super high alumina brick, a high aluminum brick, two high alumina brick, three high alumina brick

Q:Which is better, the soft core or the hard core?: When the current through the wire, it will produce a magnetic field in the vertical plane space of the wire, if there is a current two wire close by in the same direction, because they produce a magnetic field in the direction is opposite, it will produce a repulsive force is due to the magnetic field force. They will mutually inhibit current intensity of the other party, caused by the reduction of current in the wire, this inhibition of each current intensity, we called wire inductance. When the AC current line frequency is high, the inductance is stronger.

Q:What should be used as binder for making high alumina bricks?: In addition, high alumina micro powder can be used as binding agent, or high alumina micro powder and clay powder are prepared according to a certain proportion, and synthetic mullite is used as bonding agent. With these binders, high alumina bricks without two expansion can be prepared.
