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
- 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: How much is a refractory brick?
- There are many kinds of refractory bricks, you have to look at what is material, the material is not the same, the price is not the same, clay brick is the cheapest, probably hundreds of dollars a ton, and corundum brick a ton of several money, silicon carbide, silicon nitride, and more expensive. And this thing is generally on t sell, the price is by a single block after conversion.
- Q: What is the main component of corundum?
- Corundum is mainly used in advanced grinding materials, watches and precision mechanical bearing materials. A ruby based artificial crystal used as a laser emitting material. Ruby and sapphire are corundum minerals. Except for the starlight effect, only translucent transparent and vivid corundum can be used as gems. The red is called ruby, while the other tones of corundum are commercially referred to as sapphires.
- Q: What material is used in an iron smelting furnace?
- Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on.
- Q: What are the advantages of refractories?
- Aluminosilicate refractory refractory material refers to SiO2-Al2O3 as the main ingredient, according to how much the Al2O3 content can be divided into semi silica (Al2O3 15~30%), clay (Al2O3 30~48%), high alumina (Al2O3 > 48%) three.
- Q: What does refractory consist of?
- According to the shape of the product is shaped and unshaped refractory materials two categories, according to the chemical properties of acidic, neutral and alkaline refractory materials three categories, commonly used as refractory material of alkaline and neutral, such as magnesia, alkaline burned magnesia brick, magnesia chrome brick, magnesia calcium brick, high alumina brick, corundum neutral brick, clay brick, including: unshaped castable, ramming material, gunning material, coating material, dry vibration material etc..
- Q: What's the jade stove for?
- Is it a furnace made of corundum or a furnace for smelting corundum?Corundum brick stove is commonly used as a refractory material sintering furnace, can be fired refractoriness in refractories, below 1700 degrees such as brick, corundum brick, brick, alumina hollow ball and so on
- Q: What equipment is used for producing diamond blanks? How much is the investment?
- You'll have to invest about about one million if you want an electric furnace. A power distribution room is easiest to approach one hundred thousand. Electric furnaces, power distribution cabinets and transformers must be around one hundred and ten thousand.
- Q: Can the PE sintering plate dust collector be suitable for dust removal in the coking plant?
- Do not know where the coking plant do dust treatment, processing conditions are different, the dust collector is not the same
- Q: What problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?
- The expansion curves of fused cast AZS brick at 1000 DEG C near a crystal anomaly, its internal changes of ZrO2 crystal are reversible, with large volume change, therefore, products containing ZrO2, should not be used in the temperature of 1000 DEG C, often have sharp fluctuations in the position. When baking the kiln, the temperature can not be too large at 900~1150 degrees centigrade. Generally, the temperature can not exceed 15 degrees /h, and the temperature should be raised steadily. Some parts to prevent the cold, with other brick protection, to prevent explosion.
