What Kind of Ramming Material is Used for the Lining of the Intermediate Frequency Furnace?

The choice of ramming material for the lining of the intermediate frequency furnace depends on the atmosphere in the furnace. Because the working atmosphere of the intermediate frequency furnace lining is neutral, acidic, alkaline, and composite. And the intermediate frequency furnace is divided into core induction and coreless induction furnace. So, what kind of ramming … Read more

Carbon Refractory Ramming Material for Blast Furnace

In the monolithic refractories, the proportion of aggregate and powder is relatively large, while the proportion of binder and other components is relatively low. Unshaped refractories are mainly composed of some aggregates and powders. Because the refractory ramming material is mainly used in the place where it is in direct contact with the melt, the … Read more

Where Can I Buy High-Quality Refractory Cement for Sale?

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

Introduction of Two Kinds of Refractory Castables for Cement Kiln

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

Construction Methods of 3 Different Types of Refractory Ramming Materials

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

How Many Types of High-Aluminum Castables are There?

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

What are the Disadvantages of Refractory Mortar Made with Water?

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
