High-temperature refractory brick refers to a type of refractory material that can withstand high temperatures without being damaged. It is commonly known as firebrick and is widely used as the lining material in high-temperature industrial kilns and furnaces.
High-temperature refractory bricks are made by mixing refractory raw materials into a clayey mixture, filling the mixture into molds, and then high-pressure molding with a friction brick press. After drying and removing a portion of the free water, the bricks are fired at high temperatures. There are various types of high-temperature refractory bricks, including silica, semi-silica, clay, high alumina, magnesia, magnesia-carbon, magnesia-alumina, and many more. If you directly inquire about the price per ton of high-temperature refractory brick, I can provide you with a range of prices for different types. Therefore, as a purchaser, it is crucial to make accurate inquiries. How can you achieve this?
(1)Material of the high-temperature refractory brick: High-temperature refractory bricks can be classified into acidic, neutral, and alkaline types, depending on the working environment of different industrial kilns. They are designed to resist the corrosion of acidic, acidic-alkaline, and alkaline metals or gases.
(2)Application of the high-temperature refractory brick: Different parts of high-temperature kilns or thermal equipment require different materials. To reduce costs, it is essential to select the appropriate high-temperature refractory brick based on the actual production environment and temperature. For example, the high-temperature refractory bricks used in different parts of a blast furnace, such as the hearth (upper, middle, lower), bosh, bottom, and belly, vary.
(3)Operating temperature of the high-temperature refractory brick: The operating temperature is often about 400°C lower than the refractoriness temperature. It can be lower due to factors such as material erosion, chemical corrosion, and pressure in high-temperature environments. For example, if the operating temperature is below 1000°C, clay bricks can be used, and their price is around 1000 RMB per ton. If the operating temperature is around 1200°C, three-grade high alumina bricks can be used, and their price is around 1300 RMB per ton. The higher the operating temperature, the higher the content of the main refractory raw material used, and thus, the higher the price.
(4)Size and specifications of the high-temperature refractory brick: High-temperature refractory bricks come in standard sizes , as well as special and customized sizes. Standard-sized bricks are commonly stocked by manufacturers, while special-sized bricks require customized molds, which may incur additional costs.
(5)Quantity and freight of the high-temperature refractory brick: The quantity directly affects the price, as high-temperature refractory bricks are usually sold by the ton. If the demand is low, they can be sold in smaller quantities. Additionally, the distance between global purchasers and our factory, as well as the need for pallet packaging and delivery to the construction site, directly impacts the freight cost.
In conclusion, determining the price per ton of high-temperature refractory brick requires inquiry skills. Only by understanding the five factors mentioned above can manufacturers provide accurate quotations.
