In recent years, industrial kilns have higher and higher requirements for product quality and energy-saving production. Therefore, in the selection of refractory materials for rotary kilns, more and more attention is paid to the cost reduction caused by energy saving and consumption reduction after the use of refractory materials. According to the needs of customers, … Read more
Refractory cement refers to cement with refractoriness not less than 1580°C. Refractory cement is made of high-quality bauxite and high-quality lime as raw materials, mixed in a certain proportion into raw materials with appropriate components, and after sintering, the clinker with aluminate as the main component is obtained. It is ground into fine powder to … Read more
Because the cement rotary kiln has an alkaline atmosphere, alkaline refractory bricks are used in both the high-temperature zone and the low-temperature zone, and the proportion of refractory castables is gradually increasing. For example, alkali-resistant castables and high-strength alkali-resistant castables for preheaters and tertiary air ducts. Cement rotary kiln preheater 4-5 level cone, blanking pipe, … Read more
Refractory ramming materials are classified into clay ramming materials, high alumina ramming materials, carbon ramming materials, magnesia ramming materials, and dolomite ramming materials. The construction methods are also different. The following describes the construction methods of three different types of ramming materials commonly used. Construction of High Alumina (Clay) Ramming Material (1) Stirring. First, add … Read more
High-alumina refractory castable is the kind of the most widely used castables. High-aluminum castables have the characteristics of high refractoriness, low airtightness, thermal shock resistance, and corrosion resistance. The matrix of the high-alumina raw materials is different, and the castable matrix produced is also different. They can be lined in various furnaces such as boilers, … Read more
Refractory mortar is referred to as refractory clay or fire mortar, which is composed of refractory powder, binder, and admixture. Almost all refractory raw materials can be made into powder used to prepare refractory mortar. The ordinary refractory clay made of refractory clinker powder and an appropriate amount of plastic clay as a binder and … Read more
Refractory spray coating is a kind of new technology material, which promotes the development of high-tech technology. Refractory spray paint is a relatively widely used paint in the chemical industry. Refractory spray paint can make pipelines, equipment, and buildings last longer, and the use of this spray paint can reduce the number of repairs. Get … Read more
The monolithic refractories are the mixture composed of refractory aggregate and powder, binder or other admixtures in a certain proportion, and can be used directly after mixing with appropriate liquid. Refractory aggregate generally refers to particles with a particle size (ie, particle size) greater than 0.088mm. It is the main material in the structure of … Read more
Silica ramming material for intermediate frequency furnaces without baking. Silicon ramming material is a semi-dry, bulk refractory material formed by ramming. Generally, particles and fine powders made of high-alumina materials are made according to a certain grade and adding an appropriate amount of binder. During construction, ramming is required to compact the structure. Get Free … Read more
The role of adding high-alumina cement to refractory castables is mainly for binding. The higher the alumina content, the higher the refractoriness. The lower the alumina content, the higher the calcium oxide content. Add high-alumina cement as a binder to de-mould the refractory castable within 24 hours. High alumina cement will affect the fluidity of … Read more
