What is the purpose of using a backing plate during refractory installation?

Using a backing plate during refractory installation serves the important function of aiding in the removal of the applied refractory. The backing plate acts as a support layer that allows for a clean and efficient demolding process once the refractory material has set. This is particularly important because it helps to ensure that the installed refractory can be removed without damage, thus preserving both the integrity of the refractory itself and the underlying structure it is meant to protect.

The backing plate essentially provides a controlled environment during the curing and hardening phase of the refractory, assisting in achieving the desired bond and surface finish. When it comes time to remove the refractory, this backing plate facilitates the separation by providing a smooth and stable surface that can prevent the material from adhering too strongly to the installation area. This is a crucial consideration in environments where maintenance and potential replacement of refractory linings need to be conducted efficiently.

In summary, the backing plate's role in promoting easier removal of the refractory is a significant aspect of its use during installation.
