Embodiment 1

[0018] Put 30% of limestone (unit is percentage by weight, the same below), 30% of granite, 30% of albite, 5% of alumina and 5% of magnesium carbonate into the ball mill, fully grind for 8 hours, add the total amount of the above raw materials Mix 2% water for 10 minutes and then sieve; introduce the sieved material from the top of the drying tower and receive it with a trolley at the bottom of the drying tower; scrape the mixed material in the trolley and push it into the tunnel kiln. After preheating at 600°C for 2 hours, heat up to 1200°C for 5 hours; take out the bricks in the cart after cooling to room temperature, and cut them into blocks as needed.

Embodiment 2

[0020] Put 20% of limestone (unit is percentage by weight, the same below), 45% of granite, 20% of albite, 10% of alumina and 5% of magnesium carbonate into the ball mill, fully grind for 9 hours, add the total amount of the above raw materials Mix 4% water for 13 minutes and then sieve; introduce the sieved material from the top of the drying tower and receive it with a trolley at the bottom of the drying tower; scrape the mixed material in the trolley and push it into the tunnel kiln. After preheating at 650°C for 1.5 hours, heat up to 1250°C for 4.5 hours; take out the bricks in the cart after cooling to room temperature, and cut them into blocks as needed.

Embodiment 3

[0022] Put 35% of limestone (unit is percentage by weight, the same below), 20% of granite, 30% of albite, 5% of alumina and 10% of magnesium carbonate into the ball mill, fully grind for 10 hours, add the total amount of the above raw materials Mix 5% water for 15 minutes and then sieve; introduce the sieved material from the top of the drying tower and receive it with a trolley at the bottom of the drying tower; scrape the mixed material in the trolley and push it into the tunnel kiln. After preheating at 700°C for 1 hour, heat up to 1300°C for 4 hours; take out the bricks in the cart after cooling to room temperature, and cut them into blocks as needed.

Abstract

The present invention discloses a vitrified fireproof brick, which comprises, by weight, 20-45% of limestone, 20-45% of granite, 20-45% of albite, 5-15% of magnesium carbonate, and 5-15% of alumina. The present invention further discloses a preparation method for the vitrified fireproof brick. According to the present invention, the vitrified fireproof brick has characteristics of excellent physical property, excellent sintering property and light weight; and double heating foaming is adopted, such that the size of the gas holes in the brick is uniform, and the mechanical strength of the brick is further enhanced.

Description

technical field [0001] The invention belongs to the field of refractory materials, and in particular relates to a vitrified refractory brick and a preparation method thereof. Background technique [0002] At present, refractory bricks have been widely used in metal smelting industry and other fields that require high temperature resistance. Some companies have begun to try organic foam bricks as the main building material to repair residential houses, but this type of organic foam bricks sometimes produces smoke and other toxic organic gases at high temperatures, which is not feasible for long-term residential use; while bricks The quality is too large, the mechanical strength is low, and it is not suitable for high-rise buildings. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide a vitrified refractory brick for the deficiencies of the prior art. [0004] Another object of the present invention is to provide ...
