Baffle brick
Baffle brick can ensure the best performance and service life of heat storage body in the process of use, greatly reduce the shutdown time of steel plant and reduce the production cost.
Description
Overview
The baffle brick and honeycomb are used in various regenerative combustion systems, which are used at the front end of the regenerative heater, and are generally installed behind the burner of the regenerative furnace to support and strengthen the ceramic heat storage material. Its function is to protect the regenerator and prolong its service life. Therefore, high temperature resistance and thermal shock performance are the primary factors for the selection of baffle bricks.
