The raw material for the refractory brick is processed to remove the impurities. At high temperatures, Neutral refractory materials that are not easy to react significantly with acid or alkaline slag are called neutral refractories, such as carbon refractories and chromium refractories. They have good thermal spalling resistance. Since Zirconia shows very low thermal losses and does not react readily with liquid metals, it is mainly useful for making refractory crucibles and other vessels for metallurgical purposes. What are Refractory Materials ⢠Refractories are inorganic non-metallic material which can withstand high temperature without undergoing physico â chemical changes while remaining in contact with molten slag, metal and gases. A neutral condition would indicate that an Al2O3, SiC, or chrome type refractory material should be considered. } Refractory materials must be strong at high temperatures, resistant to thermal shock, chemically inert, and have low thermal conductivities and coefficients of expansion.. Application:industries of blast furnace, hot blast stove, electric furnace, refining furnace and glass furnace Once the bricks are formed and any subsequent procedures performed, they are dried to remove excess moisture that might otherwise cause cracking during the ensuing firing process. NOVA Refractories A.D. (NOVA), was founded in December 2013 following which it acquired the existing refractory plant and assets in Pehchevo, Macedonia. Silica SiO2 1728 Acid refractory Alumina Al2O3 2010 Chrome Cr2O3 2265 Zirconia ZrO2 2670 Neutral refractory Lime CaO 2614 Magnesia MgO 2800 Basic refractory Of these oxides, chrome in the form of chromite is the most cost effective. Dense refractories are heavy with low porosity but high mechanical strength. Ramming material refers to unshaped refractory which is constructed by ramming (manual or mechanical) method and hardened under the heating effect higher than normal temperature.By certain gradation of refractory aggregate, powder, binder, water or other liquid admixture through mixing.According to the material ⦠Chromite: Chromite refractories are ⦠Application: mainly used for coal chemical industry, chemical industry furnace, alkali-free glass fiber kiln, waste incinerator and other key parts of the furnace.
