"浇灌耐火材料" can be translated as "casting refractory materials" or "pouring refractory materials" in English, depending on the specific context and the process being described.
"Casting" typically refers to the process of pouring molten material into a mold to form a desired shape, which is often used in the manufacturing of refractory components.
"Pouring" is a more general term that simply means to cause a liquid to flow out of a container, and it can also be used to describe the act of delivering refractory material to its intended location, though it may not convey the same level of precision in manufacturing as "casting".
In the context of refractory material application, especially when referring to the installation or repair of refractory linings in furnaces or other high-temperature equipment, "pouring" might be more appropriate if the focus is on the delivery of the material, whereas "casting" would be more suitable if the focus is on the shaping of the material into a specific form. However, in many cases, the two terms can be used interchangeably depending on the level of detail and precision required in the description.
