FAQ
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.
Q5: Can you give me a brief introduction of the application of your products?
A5: CNBM (China National Building Material) core refractory business comprises the production, sale and installation of high-grade refractory products, the development and implementation of customized system solutions as well as rendering outstanding services for the key industries in Glass, Iron& Steel, Petrochemical, Cement, Ceramic and Nonferrous Metals.
- Q: Whether yellow dextrin is used in refractory bricks?
- The production of refractory bricks needs yellow dextrin as bonded materials.
- Q: What is the material of refractory brick used in the high temperature zone of the kiln?
- The ordinary generally use clay high alumious fireclay brick. GB/T 3994-2005 insulating refractory brick. What with good material is high-grade thermal insulation refractory brick. GB/T 3995-2006, high alumina thermal insulation refractory brick , model A13, is made of aluminium oxide, A13 50U, senior heat insulatio brick B5
- Q: What is refractory brick? What is refractory clay? ?
- Refractory bricks and refractory soil are all refractory materials. Generally they can be seen in the coke oven. The refractory brick is generally yellow. A steel brick is a kind of refractory brick. Its heavier several times than ordinary brick .
- Q: Characteristics of refractory bricks
- The ability to resist rapid changing temperature and not to be destroyed is 6, it refers to the change of the volume expansion and contraction in the same temperature change. the porosity is 3, this parameter is very important in its own properties, anti bending strength, but as a manufacturer, you must strictly control the explicit hole through the material unit area of heat flow rate: The main composition determines the quality and characteristics of the refractory material 2: Unit volume weight, good impact resistance, abrasion resistance show good compactness: Also called high temperature load, it begins to deformation temperature, the volume density, we define such a linear change rate is 0 physical and chemical properties is 1: 5, but the heat conductivity coefficient may be large, load softening temperature, porosity: The ability to withstand shear stress is 8, compressive strength: Did not make specific requirements about thermal shock resistant performance: Resistance to anti penetration erosion under high temperature and not destroyed 7: Don't have to explain it, linear change rate, thermal conductivity, slag resistance: Also known as linear?change?on?reheating or the residual line change, if the expansion and contraction of each time is the same: Under the condition of unit temperature gradient, the service life is 4, chemical composition.
- Q: why the color of refractory brick is white after high temperature firing when the meteorite is black after the burning?
- There are different reasons. Meteorolites can mainly be divided into three types, iron meteorites (iron nickel alloy): Stone meteorites (the main component is silicate), and stony iron meteorites(the mixture of iron and silicate)
- Q: should clay or refractory cement be used to lay refractory bricks?
- structure strength of this brick lining is not good, apply some refractory mud, only use some virgin clay and corundum, many of the traditional approaches are very simple, mullite and carbon slurry, the specific products are selected according to the selected material and water glass or organic binder. binding agent can choose phosphate, silica and high alumina, clay is one part of the refractory clay, there are many kinds of refractory slurry according to the material, clay-based mud does use refractory cement and corrosion resistance is low
- Q: How about clay bricks?
- The strength of brick can be judged by the sound produced by two bricks colliding with each other.Two hands each take a brick, gently hit, such as a uniform, crisp sound, indicating brick high strength, good quality, if the collision sound hoarse or stuffy, it shows that brick strength is low.2. to observe the crack state of bricks, elliptical repeat crack if large surface of the brick on the head, like twistcore, called "spiral brick"; some bricks will be broken, the shell off angle, crack and other symptoms, hand picked up the pieces of a pinch, immediately in powder form. The inner core is yellow and honeycombed. It is called "crisp brick", which belongs to the waste brick.3. to observe the color of brick brick brick section: open, heart was uniform black, no unburned carbon brick, high strength of such. On the contrary, the intensity is low.
- Q: Whether the fire bricks are needed to be poured before construction?
- It should be properly watered, according to its water absorption rate: Need to soak and dry in the shade. There is no need to do like the ordinary red brick
- Q: What is the difference between a clay brick and a red brick?
- Clay bricks burn red and red brick. Burnt blue. Green brick.Clay bricks are called sintered clay bricks.The construction methods are the same as those of the two. No difference.
- Q: The boiler is divided into several categories according to the structure, what characteristics does each have?
- package boiler and assemble boiler are divided into vertical boiler and horizontal boiler. Vertical boiler. Assembled boiler adapts to boiler more than 6 tons, the package adapts to boiler less than 10 tons.
