This may be the first time for you to hear the term refractories. This is no wonder, since we have little opportunity to experience refractories in our everyday lives. As a matter of fact, the necessities of life, such as personal computers, smartphones, and cars, cannot be created without refractories. They are necessary to create materials for the things around us. Yotai’s refractories support our lives behind the scenes.
What are refractory products？
In the process of manufacturing iron, cement, and copper, they need to be melted and baked at high temperatures. However, many pieces of equipment cannot stand such high temperatures because they are made of iron and stainless steel.
Therefore, refractories that have higher heat resistance than the materials to be melted and baked are essential.
Who needs our products？
Refractories are needed in a wide variety of industries and are always used in plants with high-temperature treatment processes. The required performance of a refractory depends on the type of material to be heat-treated and the place where it is used.
We offer products with different quality levels as needed in the respective industries and provide optimum products to customers by deepening technological exchanges with customers.

How long refractory products life?
Refractories are always exposed to high temperatures and deteriorate over time. The lifetime of refractories varies depending on the application and range from only one day to 10–20 years. The service life is greatly affected by the type of industry and place where refractories are used.
