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 problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?
Cast brick and clay brick masonry contact, eutectic phenomenon will occur at 1300 degrees Celsius, the selection of refractory materials, should avoid eutectic phenomenon serious two kinds of refractory materials such as brick masonry contact, in the following cast brick, the most vulnerable to erosion fused zirconium corundum brick.
Q:What are the main constituents of refractory bricks
Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon, aluminum, clay and so on:According to the composition of refractory bricks, they can be divided into five major categories, namely, silicon aluminum refractory bricks, basic series refractory bricks, carbon containing refractory bricks, zirconium containing refractory bricks and insulating refractory bricks. Any furnace is not made of only one kind of refractory brick, and it needs different fire bricks to match with each other. The following five categories of refractory bricks are described in detail.
Q:Can the fire clay be reused?
Refractory soil cannot be reused.Clay refractory soil 1, characteristics and uses: Clay refractory brick is a weak acid refractory material, its thermal stability is good, suitable for hot air furnace, all kinds of boiler lining, and flue, smoke room, etc.. 2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
Q:High temperature refractory material
Acid refractory with silicon oxide (SiO2) as the main ingredient, commonly used are silica brick and clay brick is siliceous. Products containing more than 93% SiO2, the use of raw materials with silica, silica and other waste brick. Acid slag erosion ability is strong, but vulnerable to the erosion of basic slag, its softening temperature is very high that is close to the refractory, the volume does not shrink after repeated burning, or even a slight swelling, but the thermal shock stability. Silica is mainly used for thermal equipment of coke oven, glass furnace, furnace and other acidic silica brick, according to the physicochemical indexes and SiO2 content can be divided into several levels, mainly brick for glass furnaces and used for coke oven two kinds of brick clay brick. With refractory clay or bauxite clinker as main raw material, containing 30% to 46% of alumina, refractory degrees 1580 to 1770 DEG C, weak acid refractory material, heat shock resistance, resistance to acid slag, wide application Pan, clay brick with refractory clay as main raw material is called ordinary clay brick, made with bauxite clinker as main raw material, the porosity in the clay brick below 17% is called low porosity clay brick. Two kinds of clay brick and according to the physicochemical indexes which were divided into several grades, the price difference between ordinary clay brick and low porosity clay brick greatly.
Q:Can the PE sintering plate dust collector be suitable for dust removal in the coking plant?
The sinter plate dust collector is also called plastic plate dust collector. The utility model has the advantages that the utility model can adapt to various complicated working conditions, the dust removal rate is 99.99%, the utility model has the advantages of long service life, stable operation, high temperature resistance, and the utility model is a leading dedusting equipment in china.
Q:What is the price of concrete self insulation bricks?
Insulation brick prices also have a great relationship with the material and workmanship, such as clay brick price is much lower than high alumina brick, mullite and corundum brick prices will be higher.
Q:Wave tile and throwing glaze, tile which good?
These two tiles have their respective advantages and disadvantages, in fact, to say which kind of good, mainly depends on the decoration of personal preferences and the location of the shop. If it is only the shop wall, then design and pattern rich whole glazed tile is good, it can make the room impressive, improve decorative effect, make the decoration style to fit the characteristics of his personality. In addition, clean up is relatively easy, not easy to contaminated with oil stains and other pollutants. If it is laying floor tiles, tile Douglas suggested the use of tiles, tiles of good antiskid effect, water absorption rate is relatively low, so the kitchen toilet bathroom and other wet places is not easy to water seepage, improve the convenience of life.
Q:What kind of fused corundum corundum brick should be used for each part of the glass furnace?
In addition to AZS33# and AZS same co crystallization in vitro, 36#AZS due to the increase of chain like zirconia brick more crystals, while the glass phase content is low, so 36# AZS corrosion resistance has been further enhanced, so is suitable for the rapid flow of molten glass or high temperature region.AZS36 s is an excellent product in the AZS series. It has high resistance to glass liquid erosion and low pollution. It is usually used in the key parts of the glass furnace, such as the pool wall near the hot spot.
Q:How to improve the induction furnace campaign, from the promotion of refractory life start
According to the workpiece, choose the appropriate hardware castable, corundum brick or refractory bricks, etc.
Q:What are the refractory materials?
Not a good answer. You can sort out, such as: neutral, alkaline, acid refractory. Different kinds, of course, raw materials are different.For example: MgO-C brick basic refractories: magnesia (fused, high purity graphite) + + + phenolic resin additives (silica fume or aluminum or silicon carbide or high temperature asphalt) etc..
