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 refractory materials are adopted in each part of the blast furnace
Bosh temperature reaches 1600~1650, high alumina brick, corundum brick or silicon carbide brick. The upper hearth tuyere zone near the temperature at 1700~2000 Deg. C, the use of sillimanite brick, corundum and silicon carbide refractory filler, Shi Mozhi. Bottom temperature at 1450~1500 Deg. C, the use of graphite bricks and microporous carbon brick, now also used corundum brick, Gang Yumo brick and synthetic mullite brick.
Q:What are the advantages of refractories?
The castable refractory is a refractory product with a certain shape after being melted at high temperature by a certain method. Neutral refractory is refractory material which is difficult to react with acid or alkaline slag at high temperature, such as carbon refractory and chrome refractory. Some of the high alumina refractories are also attributed to this category.
Q:What refractory materials are used in industrial furnaces?
Economically, it is necessary to do technical and economic analysis when selecting materials reasonably. Under the premise that the technical indexes agree with the working conditions of the furnace, the refractory materials with low quoted price should be used as much as possible, without high-grade finished products. To think about whether to make self (such as irrigation, refractory concrete) as far as possible to repair old.
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 price of concrete self insulation bricks?
If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)
Q:Wave tile and throwing glaze, tile which good?
Vitreous tile is all ceramic tile, the material is hard, strong wear resistance, smooth finish is very good, in general, looks very bright. Microcrystalline brick, corundum brick Market said, they really mean bohuazhuan. Because of its low water absorption and high strength and hardness, glazed tile has been widely used. Many hotels, shopping malls and office space are widely used glass tile.
Q:Which is good, glazed brick and whole cast glazed brick?
The main advantages of all glazed glazed tiles are that they can be very rich and beautiful in texture and pattern, and they are suitable for family decoration, and can choose patterns according to their own family decoration style. Compared to the glazed tile, it has better pollutant discharge performance, and many pollutants are difficult to penetrate into it.
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 is the difference between T3 refractory bricks and high alumina refractory bricks?
The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)
Q:What kind of refractory material will be used in the glass kiln
High temperature & glass corrosion performance of the brick is slightly lower than that of chromium oxide, also by isostatic pressing forming method, its technical indicators ZrO2>65%, <2.0% porosity, volume density of about 4.25g/cm3, the temperature in E glass is higher than 1370 DEG C have erosion. Used in the E glass melting pool unit kiln glass temperature slightly lower at the end of the transition path, forming the bottom of the pool and forming path path flow tank and bushing support brick etc.. In addition, the dense zirconia brick is used as the backing brick of the dense chrome brick.
