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:The difference between clay bricks and clay bricks?
According to the hole rate: solid brick (no hole or hole rate less than 25% bricks), porous brick (hole rate is equal to or greater than 25%), the size of the hole is small and the number of bricks, usually used in load-bearing parts, higher strength level. Hollow brick (hole rate equal to or greater than 40%, large pore size and small amount of brick, commonly used in non load parts, low strength grade).
Q:90 porous brick and ordinary shale brick, clay brick difference
Porous brick refers to clay, shale and fly ash as the main raw material, porous brick after molding, roasting and hole rate of not less than 15%~30%, the pass is a round hole or non circular hole, the small size and number of loading sintered porous brick has a rectangular or circular hole, is not equivalent to as long as the bricks some hole. The utility model can directly replace the sintered clay brick, and is widely used for various bearing, thermal insulation, bearing and frame filling construction walls with wide popularization and application prospect.
Q:How many years are the service life of chimney lining refractory brick?
Capacitance magnesite, seawater magnesite, should be the alkaline refractory brick, magnesia-alumina spinel can absorb hydrogen fluoride, generally are magnesia brick, magnesium iron ore, forsterite, dolomite, magnesium dolomite, magnesium silica sand, magnesia-chorme spinel and magnesia chrome sand: Magnesia mineral, magnesium calcium sand, magnesite, magnesium dolomite sand, dolomite, mainly is cordierite
Q:several refractory brick of rotary kiln several is damaged, how many refractory bricks should be replaced?
In general, if the brick inside the kiln break or loose core, the bricks of whole circle should be replaced, if only mend by replacing a damage part is also ok, but the service life is shorter.
Q:Why do some people say that clay brick insulation effect is good, and some people say that bad, in the end what is right?
Now is the best thermal insulation hollow powder briquette, because it is hollow, blocking the heat transfer, plus foam insulation on the outside, good insulation effect,
Q:In tunnel kiln, what is the meaning of refractory proportion 2.0?
The proportion of refractory bricks is related to the density.
Q:Solid brick and clay brick which is expensive
Red brick generally refers to sintered clay bricks. Generally divided into standard brick (Shi Xinzhuan), porous brick (KP brick), hollow brick (KM brick) and so on.
Q:Are refractory bricks necessarily needed to build a kitchen stove?
It will be better to use refractory bricks for long term because of its high temperature resistance
Q:What's the price of clay bricks?
Clay brick in the fast price of 2.4 yuan or so, the price of 650-800 yuan per ton. Mainly depends on the amount of aluminum. Clay brick consists of heavy clay brick and light clay brick.
Q:How much refractory material is required for 1 million tons of coke oven
This depends on the number of specific cubic, different factory designs different boiler, we need volume to caculate.
