Abstract
A bottom brick for tin pool used for the float glass production line is prepared from Si-Al clinker, low-Al fine powder, silicon brick powder, fine silicon powder, high-Al cement as binder, water reducing agent and water. Its advantage is long service life.
Description
Technical Field
The invention relates to a tin bath bottom brick for building a tin bath in a float glass production line.
Background
At present, most of the methods for producing the tin bath bottom brick adopt sintered flint clay as aggregate and raw clay as bonding agent. The tin bath bottom brick produced by the raw materials has the following defects: (1) the raw clay has larger shrinkage after drying and sintering, and through capillary pores are easily formed between the aggregate and the matrix, so that the alkali corrosion resistance of the tin bath bottom brick is reduced; (2) the main mineral composition of raw clay is kaolin or montmorillonite, which is converted into mullite after firing:
the bottom of the tin bath is paved by clay bricks. During the use process, ion exchange is carried out between the upper surface of the tin bath bottom brick and the glass belt through tin waves, alkali ions in the glass are continuously diffused into the bottom brick, and react with mullite on the substrate part of the bottom brick under the action of temperature to form nepheline:
mullite nepheline
The mullite is accompanied with large volume expansion in the process of converting into nepheline, so that the upper surface of the tin bath bottom brick is easy to peel off, thereby influencing the service life of the tin bath bottom brick.
Disclosure of Invention
The invention aims to provide a nepheline-resistant tin bath bottom brick.
In order to achieve the aim, the technical scheme of the invention is to adopt a tin bath bottom brick which comprises the following components in parts by weight:
silicon-aluminum clinker 60-90
220-mesh and 250-mesh 20-30 low-aluminum fine powder
Silica brick powder greater than 250 meshes 5-10
4-6 parts of silicon micropowder
Binder 3-5
0.05-0.2 of water reducing agent
Water 5.0-7.5
The aluminum-silicon clinker comprises (by comparison with the total raw material composition) 15-20 parts of 0-1mm, 10-15 parts of 1-3mm, 15-25 parts of 3-5mm and 20-30 parts of 5-8 mm.
The low-aluminum fine powder can be one of mullite powder, bauxite powder and clay powder (flint clay powder).
The silica brick powder is sandstone powder.
The binding agent is high-alumina cement.
The water reducing agent is sodium tripolyphosphate.
The matrix part of the bottom brick of the tin bath of the invention adopts the ground calcined siliceous mineral and the siliceous mineral rich in glass phase as the filler of the aggregate, adds a small amount of silicon powder as the sintering accelerant, uses a small amount of high-alumina cement as the bonding agent, and does not adopt raw clay as the bonding agent, thus thoroughly changing the mineral structure of the matrix part of the bottom brick. Because the matrix part contains higher glass phase and a small amount of mullite phase, the shrinkage of the matrix part after sintering is extremely small, and most of air holes exist in a closed manner, so that nepheline is not easy to form, thereby prolonging the service life of the tin bath bottom brick. The tin bath bottom brick is dissected after being used for 8 years of cold repair on a tin bath, and observation and analysis are carried out under a microscope, and only 2mm of the upper surface of the bottom brick is found to have very little nepheline, and 5mm away from the upper surface has alkali diffusion, so that the tin bath bottom brick cannot be damaged.
Detailed Description
Example 1
The tin bath bottom brick of the invention is prepared from the following raw materials in parts by weight: 15 parts of 0-1mm aluminum-silicon clinker, 10 parts of 1-3mm aluminum-silicon clinker, 15 parts of 3-5mm aluminum-silicon clinker, 20 parts of 5-8mm aluminum-silicon clinker, 20 parts of 220-plus-250-mesh mullite powder, 5 parts of silicon brick powder, 4 parts of silicon micropowder, 3 parts of high-alumina cement, 0.1 part of sodium tripolyphosphate and 6.9 parts of water. The high-alumina cement in the proportion is used as a bonding agent, and is formed by pouring and vibration, and the bottom brick of the tin bath is obtained by firing at 1300 ℃.

The high-alumina cement in the proportion is used as a bonding agent, and is formed by pouring and vibration, and the bottom brick of the tin bath is obtained by firing at 1325 ℃.
Example 3
The tin bath bottom brickof the invention is prepared from the following raw materials in parts by weight: 20 parts of 0-1mm aluminum-silicon clinker, 15 parts of 1-3mm aluminum-silicon clinker, 25 parts of 3-5mm aluminum-silicon clinker, 30 parts of 5-8mm aluminum-silicon clinker, 25 parts of 220-mesh and 250-mesh clay powder, 5 parts of kyanite, 6 parts of silicon micro powder, 5 parts of high-alumina cement, 0.05 part of sodium tripolyphosphate and 7.5 parts of water. The high-alumina cement in the proportion is used as a bonding agent, and is formed by pouring and vibration, and the tin bath bottom brick is obtained by firing at 1350 ℃.
