Premium Raw Materials Used In Refractories To Meet International Standards
Refractory industrial products are designed to meet various applications in the industrial sector. Over the years, with advanced technologies introduced, these products have been modified to suit the requirements of the area where it is to be applied. Premium raw materials are used to make these heat resistant products and care has to be taken to ensure that the tensile strength, durability and resistance are guaranteed to meet the toughest conditions.
Products manufactured include fire bricks, fire cement, plastic mouldable, refractory cement and refractory castables that are used in steel plants, foundries and heat and power stations. They are also used in glass and chemical works, coke plants, ceramics, incinerators, renewable energy, petrochemical industry and sugar refineries. Thanks to the initial discovery of the way fire cement was formulated in UK, manufacturers began to work on the findings and developed and devised new ways for coming up with refractory mortars.
Refractory materials include castables, mouldable & RAMS, Cement Mortars, chemical and acid resistant cement, fire cements and putties and zircon. Refractories are basically heat resistant materials that are normally used to line high temperature furnaces as well as processing units that require high temperatures. They have to be able to resist thermal stress and physical wear, chemical corrosion and abrasion.
Many shops online offer quality products to customers that are of the highest standard. All of them may not be able to offer guaranteed service and quality and it is important to find the provider who can handle the right standards and specifications. Many companies may require customized sizes for a specific application. It is important to find a company that manufactures refractories at economical rates.
Fire bricks are blocks of refractory ceramic material that is used to line fireboxes, kilns, furnaces and fireplaces. They are made with special minerals and dense clay bricks that are operated on very high temperatures. These bricks can be used in domestic applications such as stoves, fireplaces, circulators, pizza ovens, barbecue grills, inserts and furnaces. If the bricks are of superior quality, they will prove to be energy efficient and can be used over a long period and require little maintenance. This will also help to reduce the production time and improve the manufacturing process.
In order to save energy the refractory brick has a low thermal conductivity. In places such as the wood-fired furnace or kiln, abrasion from wood takes place due to high temperatures. Fluxing from slag or ash is also noticed when there is extreme thermal, mechanical or chemical stress. The high thermal mass that is contained in dense brick is able to retain heat in the oven even after the fire is out. This is due to the fact that these bricks contain 30 to 40% alumina and are made by firing a composition that is clay based in kilns until it is semi-vitrified and in some instances, glazed. The main raw material used is chamotte along with other materials. Many ranges of grades correspond to different maximum service temperatures and these should be noted when ordering the same.
