Q:does the electric kiln burner need to be sealed?
seal when open the kiln, and observe the temperature, when the temperature reaches a point, you can move the firebrick away, and continue observing the temperature to decide whether to seal it or not, but do not seal it completely, repeat the procudure until reach the sinter point or skill requirement.
Q:What is the role of refractory brick, whether is there any books to introduce refractory bricks
Just as its name implies it is a fire burning, making stove is very good
Q:What is the perservation method for refractory bricks used for cement kiln?
The hydration resistance ability is better than the alkaline materials, 1 years will be no problem if the environment is good, alkali-resistant bricks used in cement kiln brick refractory brick (magnesia-chrome brick, the preservative time will be longer, the remaining products should also be moistureproof. No matter what refractory materials, phosphate brick. If the package is complete, it must be stored in a dry and rain-proof environment, silmo brick. Anti-stripping alumina brick, if is not immediately used, it's necessary to take measures of moisture proof, such as spinel brick must be moisture-proof
Q:What is the refractory temperature of refractory bricks?
First look at the used parts of refractory brick, anti stripping performance, these are the most basic performance factors, the refractory temperature of high alumina brick is 1770 -1790 degree, the refractory temperature of clay brick is 1380-1570 DEG C, record the anti acid corrosion data of refractory bricks, the compressive strength of refractory bricks, at the same time, you should analyze each part of the furnace pH index and sintering temperature of working. When purchasing refractory bricks, you need to pay attention to many factors, high temperature creep property, softening temperature under a fixed load, 6548, volume stability at high temperature. Because the production of the product is affected by the weather and fuel energy, etc.. 186, select the suitable refractory bricks
Q:Which is best of refractory brick press machine?
Rub press machine have been forced out. Without permanent magnet. The electric screw press machine is suitable for the forming of refractory bricks. Use Kehui switch reluctance to servo motor to drive electric screw press machine, have the ability of high quality electric screw press machine, no water cooling, high efficiency and energy saving, green and environmental protection.
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:is there any requirement for radioactive materials in refractory materials.
they all do not cause radiological hazards to the environment, so no requirements! analyze rom the element , magnesia. Do not know if it is useful, but material used by refractory materials, firstly any chemical elements are radioactive, human beings can not close, then, such as silicon dioxide: If it is radioactive. analyze from use, such as bauxite, does not have the use value
Q:The renewal of refractory brick internal the lime kiln belongs to overhaul. In the absence of production, are the replacement of valve and sporadic projects also considered overhauls? Or routine maintenance!
The replacement of refractory brick for lime kiln is definitely a major overhaul, and the replacement of the valve and sporadic items can only be regarded as routine maintenance.
Q:What material is good of refractory bricks?
It can also be divided into a variety of kinds, it mainly depends on where it is used, each has its own advantages, neutral three categories of refractory bricks have a variety of materials
Q:How can refractory bricks be punched?
Electric is ok
