Big Fireclay Bottom Block Glass Fusing Kilns Furnace Used Big Refractory Brick Fire Clay Brick Price
Big Fireclay Bottom Block Glass Fusing Kilns Furnace Used Big Refractory Brick Fire Clay Brick Price
The tin bath is the heart of the float flat glass production line, and the quality of the tin trough bottom brick is the key structural material that affects the normal operation of the tin bath. fire-clay bottom bricks are generally used. Such Big Fireclay Bottom Block are generally large, requiring a single weight of more than 50 kg, and some even weighing up to 400 to 500 kg. Big Fireclay Bottom Block is not suitable to be formed by ordinary mechanical pressing or beating method, and generally adopts a casting molding method.
The main production process of the Big Fireclay Bottom Block used for the production of float glass bottom by vibrating casting method is as follows: clay clay clinker, mullite fine powder, oxide ultrafine powder and hardener are used to form self-hardening mud. The material is formulated into a mud material which has both thixotropic properties (formed by vibrating castables) and self-hardening, and can be demolded after standing for a certain period of time after molding. In order to meet the molding process requirements, a small amount of debonding agent and a small amount of delayed coagulant are appropriately added to the composition of the ingredients. Adding a debonding agent can not only reduce the amount of water from 10% to 13% by 5.5% to 6.5%, but also obtain a uniform structure; adding a delayed coagulant can simultaneously solidify the inside and outside of the billet, thereby shortening the demolding time.
Big Fireclay Bottom Block formed by vibration casting have many
spherical gases in the mud due to the surface tension during the
vibration process, forming a closed pore. Therefore, the brick has
low gas permeability and can effectively block oxygen from passing
through the refractory material. The wall diffuses into, thereby
preventing brick cracking due to volume expansion caused by
oxidation of tin metal to tin oxide. Moreover, since the block has
a low gas permeability, the hydrogen diffusion degree is also low,
thereby avoiding glass defects caused by bubbles at the bottom of
the tin bath, thereby improving the yield of the glass.
