Vibrocast Block
Description:
Vibrocast block is a large fire clay brick formed by vibrating casting, due to the surface tension during the vibration process, most of the gas that cannot be excluded in the mud exists in a spherical shape, forming closed pores, so the brick has low air permeability and uniform organization. This kind of clay brick is generally large and requires a unit weight above 50Kg, and some even weighs 400 ~ 500Kg.
Advantage:
Low porosity, strong resistance to glass liquid penetration, precise dimension
Application:
The bottom of the glass furnace/kiln working tank and tin bath
