Spout and Repair Material manufacturers take you to understand the characteristics of unshaped refractory materials

Spout and Repair Material manufacturers tell you that common unshaped refractory materials can be divided into castables, plastics, ramming materials, gunning materials, projectiles and coatings according to construction methods and material properties.

Spout and Repair Material manufacturers tell you that the castable is a granular and powdery material made of refractory material, and is composed of a certain amount of binder and moisture. It has high fluidity, is suitable for construction by casting method, and is a common unshaped refractory that can be hardened without heating. It is composed of refractory aggregate, powder, binder, admixture, water or other liquid materials. Generally, it is cast and formed by pouring, vibrating or tamping at the site of use, and can also be used as prefabricated parts.
Refractory castable is a kind of amorphous refractory which is widely produced and used. Spout and Repair Material manufacturers tell you that it is mainly used to construct the overall structure such as the lining of various heating furnaces. Certain high-quality varieties can also be used in smelting furnaces. For example, aluminate cement refractory castables can be widely used in various heating furnaces and other thermal equipment without slag and acid and alkali erosion. In the parts that are eroded by molten iron, molten steel and slag and have high working temperature, such as tapping grooves, ladles, blast furnace shafts, tapping trenches, etc. Refractory castables made of high-quality granular and powdery materials with high alumina content and good sintering.
Another example is phosphate refractory castables, which can be widely used in heating furnaces and soaking furnaces for heating metals, as well as in coke ovens and cement kilns that directly contact the material. Spout and Repair Material manufacturers tell you that in some parts of metallurgical furnaces and other vessels that are in direct contact with slag and molten metal, repairing with high-quality phosphate refractory castables also has good results.
Spout and Repair Material manufacturers tell you that with the increase in the ratio of amorphous refractories in refractories, refractory castables will develop rapidly, and at the same time, the quality of varieties will also increase accordingly, and the focus will still be on the development of low cement and ultra-low cement. and cement-free refractory castables, select homogenized and high-quality raw materials and special aggregates according to resource conditions to improve the basic composition, research and promote the use of fiber-reinforced refractory castables and self-flowing refractory castables, and use various additives to improve refractory castables performance.
