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.


Q3: Can you offer Door-to-Door delivery?

A3: Yes, but only for some countries such us U.S., UAE, Saudi Arabia, Iran, and Russia, etc.


Q4: What is the minimum quantity?

A4: There is no minimum order quantity. Depending on the item and processing, there may be a minimum production required, however we can offer a quotation based only on the quantity you need.

Q:What matters should be noticed when using clay refractory bricks in a glass kiln?
There are a variety of products for the production of shaped and unshaped refractory clay, such as blast furnace insulation and high alumina bricks. Brick products include refractory clay bricks, plastic materials for overload, refractory clay and high alumina casting materials, etc.. In the amorphous part, if to support the horizontal induction furnace and the straight induction furnace lining, such as refractory clay and high alumina plastic
Q:How to repair the boiler?
What kind of boiler, the external wall or the furnace arch, the smoke wall, the material: High-alumina cement, refractory brick, refractory clay, knife brick
Q:when to replace the worn refractory bricks in rotary kiln?
But also depend on the other conditions of the furnace, many aspects should be understood, not only to see the degree of wear!
Q:Can thick steel plate be used instead of the furnace inside the refractory brick?
It depends on the temperature. The steel plate is a kind of heat conduction material which hasn't heat insulation, which should be based on the working environment.
Q:What materials make of clay insulating fireclay brick?
Clay insulation bricks are general according to the different origins of raw materials, not the same
Q:application of phosphate refractory bricks
The 4 properties of phosphate refractory bricks: (1) high strength wear resistance (2) and chemical erosion (its alkali resistant ability is better than that of clay brick and high alumina brick) (3) and good thermal shock resistance (4) high load softening temperature in rotary kiln, kilneye, kiln Zone door cover, cooling machine and lining refractory brick falling parts easy to loose
Q:There are various refractory materials inside many kilns such as refractory brick, what is the role of masonry of these refractory materials?
Heat insulation
Q:What is the perservation method for refractory bricks used for cement kiln?
The place should be dry and ventilated. Remember that the packaging can't be damaged. If is not used for a long time, put desiccant next to the bricks. Then have thermoplastic packaging again, it won't get damp. Under normal circumstances, it can be stored for 3-5 years and won't be hairy
Q:Can refractory bricks be used to pave roads or build a wall?
Refractory bricks are used to build a house, no problem
Q:what should press on the heat preserving cotton above the suspended ceiling refractory brick ?
you can also put Z shaped steel on the purline, put heat preserving cotton on the roof boarding, it is easy to oprate.
