The refractory castable is used to describe a kind of high temperature resistant concrete, so it also conforms to the principle of concrete. Such as the amount of water added is the fundamental reason to control whether the refractory castable can achieve the design strength. However, driven by interests, some construction parties will add a lot of water to the castables in order to speed up the construction progress, resulting in the service cycle of the kiln refractory lining after construction is much lower than the design requirements. , even after half a year of use, serious problems have occurred and must be overhauled 。
We know that the investment in refractory materials accounts for a very small proportion in the entire construction investment, but its impact on the future operation of the entire system is very large. Therefore, it is particularly important to control the construction process of refractory castables. Usually we should strictly implement the following regulations.
