Henan Xinmi manufacturer casting fireclay block casting kaolin block for float glass furnace tin bath bottom

As we know, the tin bath is the heart of the float flat glass production line, and the quality of the bottom bricks of the tin bath is the key structural material that affects the normal operation of the tin bath, and casting fireclay blocks are generally used.

Casting fireclay blocks are generally used at the bottom of the glass kiln. This kind of fireclay 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 large size casting fireclay bricks adopt high-power vibration platform, adopt special refractory cast material vibration molding process, kaolin raw materials, and produce large size casting fireclay 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 large size casting fireclay blocks for float glass furnace 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.

Large size casting fireclay blocks 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.
