Henan manufacturer low price casting large size fire clay brick for glass furnace
Casting large size fire clay bricks are generally used at the bottom of the glass kiln. This kind of fire clay brick is generally large, requiring a unit weight of more than 50kg, and some even weighing 400-500kg. It is not suitable to use ordinary press or ramming method to form, generally use the casting method.
Our company's casting large size fire clay bricks adopt high-power vibration platform, adopt special refractory cast material vibration molding process, kaolin raw materials, and produce large size fire clay bricks at the bottom of the glass kiln. The physical and chemical indicators and appearance of the large size kaolin casting bricks are superior to other similar products. In particular, the corrosion resistance of molten glass is much better than that of products formed by traditional mud pouring process and tamping process. It is especially suitable for building the bottom and wall of the glass melting furnace.

The main points of the production process for the production of casting large size fire clay bricks for float glass tank bottoms by vibrating casting are as follows: using kaolin clinker, mullite fine powder, oxide ultra-fine powder and hardener to form a self-hardening mud to make brick mud The material is mixed into a mud material that has both thixotropy (which can be molded by vibrating castable) and self-hardening, and can be demolded after a certain period of time after molding. In order to meet the requirements of the molding process, a small amount of degelling agent and a small amount of late-acting coagulant are appropriately added to the ingredient composition. Adding degelling agent can not only reduce the amount of water used from 10% to 13% to 5.5% to 6.5%, but also obtain a uniform structure; adding a slow-acting coagulant can simultaneously solidify the body and outside of the body, thereby shortening the demolding time.
Casting large size fire clay bricks formed by vibrating
casting, due to the effect of surface tension during the vibration
process, most of the gas that cannot be removed in the mud is
present in a spherical shape, forming closed pores, so the brick
has low air permeability and can effectively hinder oxygen from
passing through the refractory. The wall diffuses in, thereby
avoiding the brick cracking caused by the volume expansion caused
by the oxidation of metal tin to tin oxide. Moreover, due to the
low air permeability of the bricks, the hydrogen diffusion is also
low, thereby avoiding glass defects caused by bubbles at the bottom
of the tin bath, thereby increasing the yield of glass.
