types of refractory fire bricks and which one is the best for walls

Today, in order to preserve and last the buildings against wear and frequent frosts and can be used in all climatic conditions, firebrick is used. The use of firebricks is not limited to construction, but is used in many industries such as steel, cement, lead, zinc, glass, etc. Refractory bricks are used for furnaces in these industries. Refractory bricks are not limited to heat resistance,but also have other properties that we will explain below. procrastination: ✔️Composition and chemical and phase analysis ✔️Density and porosity ✔️Cold compressive strength ✔️Hot bending strength ✔️Cold bending strength ✔️Thermal conductivity ✔️Thermal expansion ✔️Dimensional changes and reheating ✔️Resistance to thermal shock ✔️corrosion resistance ✔️Impact resistance ✔️Creep resistance ✔️Abrasion Resistance castable refractory fire bricks types of refractory fire bricks including:Chrome Oxide Corundum Refractory Brick: About 95% of this type of brick is aluminum oxide and the remaining 5% is chromium oxide. Corundum chromium oxide firebrick is used inside the blast furnace for iron smelting. Conium refractory brick: The heat resistance of zirconium refractory brick is very high, so it is used in glass melting furnaces and aluminum iron melting furnaces. Chrome oxide firebrick: This type of brick is used in glass furnaces and 95% of it is chrome oxide. Industrial refractory brick: Industrial refractory bricks are bricks that have a certain shape. Such bricks are also known as kiln bricks. These types of bricks are divided into two categories in terms of appearance. An example of these bricks have standard dimensions and shape. These types of bricks are approved by most manufacturers and most of them use these dimensions to produce bricks. Another example of industrial refractory bricks are bricks that have a special shape. Such bricks are produced using a press machine. Others are produced using manual molding. Traditional refractory brick: As mentioned before, the use of bricks has long been of interest to architects and building designers. In the past, this element was used in the design of facades and different parts. Even today, traditional brick is used in facade design and interior decoration. Manual fire brick: Manual firebricks are another example of firebricks that are used in construction. Among the advantages of these types of bricks are things such as not causing dandruff, low water absorption, resistance to different weather conditions, fire resistance, the ability to manufacture according to the customer's needs, not changing color against the sun's rays, and price. He pointed out that it is appropriate. Installation of refractory bricks

castable refractory fire bricks

Applications of refractory fire bricks: Integrated steel production industry: blast furnace, heater, set of coking furnaces, cast iron mixers, ladle cranes, train cars, electric furnaces. Steel industry: Electric furnaces, converters, pits, degassing furnaces, heat treatment and refining furnaces, rolling furnaces for pressurized and moving beams. Glass industry: melting of hollow and flat glass furnaces, tin baths, annealing furnaces. Metal industry: copper smelting furnaces, aluminum furnaces, anode baking furnaces, pyrite rooting furnaces, lead furnaces, melting towers. Cement industry: rotary kilns, heat exchangers, kiln hoods, grate and satellite coolers. Waste industry: incinerators, fluidized bed furnaces for municipal and industrial waste, combustion chambers. Ceramic industry: tunnel furnaces, chamber furnaces, wagons. Petrochemical industries: gasoline furnaces, ethane furnaces and related processes, steam boilers, cracking furnaces. Various industries: vertical shaft furnaces, sugar dryers, hot gas generators for power plants, arc furnaces for foundries, vertical kilns for lime, rotary kilns for paper sectors, baking furnaces and chimneys These bricks are anti-dandruff and algae does not form on their surface. There is no limit to the size of this type of brick. Firebrick has the necessary resistance against contraction, expansion, impact, scratching and erosion. Water absorption by these bricks is negligible. Different patterns can be used in the arrangement of refractory bricks and double the beauty of the surface. Refractory bricks are environmentally friendly and do not cause any damage to it. The color of these bricks is stable and direct sunlight does not destroy the quality of their color. Refractory bricks are very resistant to high temperatures and fire. Installation of these bricks does not require the use of special tools and equipment. The material of firebrick and its high variety of colors make it match well with Iranian architecture.

Installation of refractory bricks

Refractory brick can be worked with cement mortar or glue on the desired surface. The use of refractory bricks with various designs and their combination together gives a very beautiful appearance to the building. This type of brick is used in both interior and exterior decoration of the building. Firebricks have a variety of designs and colors, so before implementing them, you must have a predetermined design for their combination, otherwise it is not possible to achieve an ideal view and a beautiful combination. Characteristics of refractory mass: In practice, a refractory material can be defined as a material that can be economically profitable for a long time at high temperatures without deteriorating its properties, both physical and chemical, as well as the conditions in which it works. Refractory materials can be classified according to different criteria: In terms of its chemical properties: It shows the reactive nature of the material (acidic, neutral or basic), its behavior against high temperature and slags and baths where chemical reactions are carried out. In terms of chemical composition: Depending on the percentage of compounds and additives, groups and subgroups are created: silica systems, silica-alumina systems, alumina systems, based on magnesium oxide, etc., with the addition of carbon, zircon, silicon carbide, etc., as well as a combination Of these formulas and special formulas. In terms of chemical nature: Valid classification for research and development of new products. The vast majority of materials are made up of oxides. In terms of shape: This method is clear and self-explanatory for the end user and is used in the development of detailed refractory engineering for each unit. It divides materials into shaped (bricks and precast blocks) and unshaped (concrete/casting and various materials such as insulating ceramic fiber products). Production purpose: They classify materials based on dense products, exposed to industrial process and insulating materials, whose mission is to retain heat inside the unit to reduce fuel consumption, as well as protect the metal casing of the unit f rom high temperatures. To buy these refractory bricks, you can contact our sales experts and get the necessary guidance from them. Due to the living conditions, nowadays there is not much time to browse the market and choose the desired material, so we can do this easily using the site.
