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.
- Q: what is consequence of high load and soft low of high alumina refractory brick ?
- softening, if not up to the design requirements, may cause vicious incident like the collapse of the stove in use. the full name is softening temperature under a fixed load, as the name suggests, it is the softening temperature after adding the load.
- Q: Should kiln be warmed before the ignition of the new furnace?
- New kiln should be slowly heated up, the time should be 20 days to more than 1 month!
- Q: What is the coefficient of heat transfer for clay bricks?
- The coefficient of heat transfer is called the total heat transfer coefficient. The current standards and specifications of the state are uniformly named as heat transfer coefficients. The heat transfer coefficient K value refers to the stable heat transfer condition, both sides of retaining structure air temperature is 1 degrees (K, c), 1s in the area of 1 square meters of the heat transfer unit, is w / (M2 - degree (W/) m - K, where K can replace c).
- Q: How much fireclay is needed per cube refractory bricks?
- Normal refractory bricks need to use 70-80kg refractory mud each cubic . In fact, this can be calculated, because the volume of refractory bricks and refractory mud density can be measured. Of course, here is an important point, that is the size of the brick seam, 1mm brick seam and 3mm is significantly different. Sichuan brand refractory mud has many kinds, like high aluminum, clay, corundum, magnesia, insulation and so on, the dosage is different.
- Q: What is common brick, firebrick and hollow brick?
- Mainly used for smelting furnace and silica brick. There won't be problem by using scientific methods. Refractory brick----is refractory material with a certain shape and size. According to the preparation process, can be divided into firing brick. Similarly. Hollow bricks are very scientific in use. The hollow brick is just a kind of building material, belonging to the layman practices, hollow clay brick, unburned brick, shale hollow brick, electric melting brick (casting brick). High temperature building materials and structural materials used as building kilns and various thermal equipments, and refractory heat insulating bricks. Professional saying within the construction industry is that the argument of prohibiting the use of ordinary brickis is not scientific; according to the shape and size, can be classified into standard brick, construction, whether there is problem or not on cement and other related ingredients is related when it is under construction, the ability of 1, and at high temperature can withstand all kinds of physical and chemical changes and mechanical action, how to design. For example, refractory clay brick, strictly implement national standards to use qualified hollow brick. 8 earthquake, high alumina brick , magnesia brick, etc. due to the security risks. Hollow brick is classified into cement hollow brick, the house that built by cement hollow brick collapsed leading to many deaths, investigate that the foundation is suitable for the use of hollow brick or not, 580 degrees - 1. Will mislead the public, the high temperature of 770 degrees Celsius, must be corrected. There will be no problem if use scientifically according to strict procedures. There will be problem if the use of the solid brick is not strictly implement the state relevant standards. Also called refractory brick, special-shaped brick and etc. Refractory material made from refractory clay or other refractory raw materials
- Q: What raw materials can be added to fireclay brick to respond to the urgent cold and urgent heat?
- The higher the impurities, there is no need to add some expensive performance-improving raw materials. But you can mainly choose high purity raw materials to proporly increase the performance of the clay brick, such as thermal shock. You can change relatively high-grade refractory brick. It depends on your conditions of usage if the requirement is strict. The thermal shock resistance of clay brick itself is not bad, and will almost all be affected, because the clay brick is very cheap, inside the glass phase more. Creep.
- Q: Whether the fire bricks are needed to be poured before construction?
- Of course, the purpose of watering is to reduce the bricks to absorb water in mortar
- Q: Can you direct the clay brick walls embryo
- Must not。 Not damp, damp, air tight, poor pressure bearing, bad adhesion between bricks and bricks
- Q: What is the difference between the refractory brick and the thermal insulation brick
- Refractory bricks are used in the stove, in order to prevent from burnouting the stove under high temperature. Thermal insulation brick is used for preserving heat, is to heat preservation
- Q: What is the raw material for the production of refractory bricks?
- Mainly Magnesium Oxide, use sodium silicate as a binder.
