Embodiment 1

[0022] Raw materials and their proportions:

[0023] 150Kg of burnt gems with a particle size of 5-3mm

[0024] 200Kg of burnt gems with a particle size of 3-1mm

[0025] Burnt gems with a particle size of 1-0mm 300Kg

[0026] 200Kg of burnt gem powder with a particle size of 0.088mm

[0027] Combined clay 150Kg

[0028] Calcium lignosulfonate 40Kg

[0029] Among the above-mentioned raw materials, the supplier of burnt gemstones is Shandong Wangcun bauxite; the combined clay is Guangxi soil; the calcium lignosulfonate is pulp waste liquid.

[0030] Prepare as follows:

[0031] 1) Add the aggregate to the kneader and mix well;

[0032] 2) mixing the coke clay and the burnt gemstone fine powder with a particle size of 0.088 mm, as a mixed powder for subsequent use;

[0033] 3) Pour the pulp waste liquid (calcium lignin sulfonate) into the kneader, and mix it with the aggregate for 5 minutes;

[0034] 4) Pour the mixed fine powder into the kneading pot and knead for 15 mi...

Abstract

A method for making tin bottom brick, is belongs to fireproof material technology areas. It includes batching, mixing, vibration and compression for molding, conservation and drying, heat treating and rubbing. It is characterized by after the mixed pug are poured into the model, vacuumpumping first then vibration and compression for molding. There are 3%-5%(weight percentages)paper pulp barren liquor in blending. The invention adopts the method of vacuumpumping first and then vibration and compression to solving the problems that the residual air leads to lamination crack when producing thicker brick.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a method for preparing tin bath bottom bricks. Background technique [0002] The tin bath is the key equipment of the float flat glass production line, and the quality of the bottom brick of the tin bath is directly related to whether the tin bath can operate normally and is an important factor affecting the quality of float glass. At present, there are four production methods for tin bath bottom bricks in China: 1) Vibration casting: the combination method is calcium aluminate cement at room temperature, and the production efficiency is high. The disadvantage is that 1 to 3% CaO is introduced into the composition. , has an adverse effect on the performance of the product: due to the increase in Young's modulus, the brick body becomes brittle, the high-temperature strength is low, the reliability in the high-temperature section of the tin bath is poor, an...
