Problems solved by technology

The current production of tin bath bottom bricks basically adopts grouting molding, vibration molding and vacuum pressure grouting molding, among which vacuum pressure grouting molding is a better one, and the quality of tin bath bottom bricks produced is better , high density, high strength, low porosity, has been popularized and applied to a certain extent, however, due to the high water content of the grouting molding, the product has a large firing shrinkage, which is easy to cause product cracks, and semi-product demoulding , The maintenance and drying treatment technology is difficult, and it is not easy to operate and master, resulting in a low product qualification rate, and due to the high water content, the time for demoulding, curing, drying and other processes is greatly lengthened, and only the drying time takes 60 days. Production Long cycle and low production efficiency

Embodiment 1

[0021] The preparation method of tin bath bottom brick of the present invention, batching weight percentage is composed of:

[0022] Morco clinker 86%, Guangdong black clay 14%.

[0023] Among them, the particle weight gradation of Moerco clinker (Zibo Wangcun bauxite) in the batching should be mastered as follows.

[0024] Coarse: 1mm≤particle diameter d<5mm pellets 32%

[0025] Medium: 0.074mm≤particle diameter d<1mm pellets 26%

[0026] Fine: 42% of powder with particle diameter d<0.074mm.

[0027] Mix the ingredients evenly, add 3.5% molding water of the ingredients, and set aside;

[0028] Put the ingredients into the forming mold, implement isostatic pressing, and the forming pressure is 150MPa;

[0029] Demolding and drying: place and maintain at room temperature for 1 day; 120°C drying time for 2 days.

[0030] The firing temperature is 1480℃~1500℃.

Abstract

A process for preparing the brick used for the bottom of tin bath includes such steps as proportionally mixing raw materials, shaping by isostatic pressing and calcining. Its advantages are high productivity, high quality, strength and density, and high resistance to corrosion.

Description

technical field [0001] The invention relates to a preparation method of a tin bath bottom brick, and belongs to the technical field of refractory product production. Background technique [0002] Tin bath bottom bricks are used in the production of float glass, and the quality of tin bath bottom bricks directly affects the normal production and operation of float glass. The current production of tin bath bottom bricks basically adopts grouting molding, vibration molding and vacuum pressure grouting molding, among which vacuum pressure grouting molding is a better one, and the quality of tin bath bottom bricks produced is better , high density, high strength, low porosity, has been popularized and applied to a certain extent, however, due to the high water content of the grouting molding, the product has a large firing shrinkage, which is easy to cause product cracks, and semi-product demoulding , The maintenance and drying treatment technology is difficult, and it is not ea...
