Application and Construction of Unshaped Refractory Ramming Material

Ramming material refers to the unshaped refractory material that is constructed by ramming (manual or mechanical) and hardened under the action of heating above normal temperature. It is made by kneading refractory aggregate, powder, binder, admixture, and water or other liquids with certain matching. According to the material, it can be divided into high alumina, … Read more

Application of Aluminum Magnesium Spinel Castable

Today, with the rapid development of metallurgical technology, the technical requirements for refractory materials for ladles are also getting higher and higher. The corundum-based Al-Mg spinel castable with ultra-low cement bonding is characterized by good spalling resistance and alkaline ladle slag erosion resistance. The life of the ladle lining is significantly improved, the consumption is … Read more

Application of Different Kinds of Refractory Ramming Materials

The basic material composition of ordinary refractory ramming materials is basically similar to that of refractory castables and plastics. It is also composed of refractory aggregates, powders, binders, and additives in proportion. The difference is that the amount of powder in the ingredients of the ramming material is more, and the amount of binder is … Read more

The Application of High Alumina Refractory Plastics in Heating Furnaces

The application of heating furnaces is very wide, such as steel smelting, petroleum, chemical industry, and so on. No matter what industry it is used in, refractory materials are an indispensable and important component of heating furnaces. The traditional heating furnace lining uses low-cement castables, but the loss of low-cement castables is faster. At present, … Read more

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

According to the needs of customers, … 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
