Description

Technical Field

[0001] The utility model relates to the technical field of fireproof bricks, in particular to a high-strength wear-resistant combined silicon carbide fireproof brick. Background Art

[0002] The ceramsite kiln is a kind of kiln for preheating and roasting ceramsite. It has a feed port and a discharge port. A heat source is provided at the discharge port. When the ceramsite kiln is working, ceramsite enters from the feed port of the kiln body, and is preheated and roasted by the heat source and then goes out from the discharge port. The temperature during roasting is relatively high, about 1400 degrees Celsius, which is higher than the melting point of steel. In order to make the ceramsite kiln work normally at this temperature, high-temperature resistant refractory bricks are installed in the kiln body. The refractory bricks installed in the existing ceramsite kiln are wedge-shaped, from the bottom to the top. Its width gradually narrows during the process. Refractory bricks are generally made of bauxite, kaolin, clay, diatomaceous earth and other materials. They have the characteristics of high temperature resistance. Even at a high temperature of 1400℃, there will be no signs of melting. However, the existing refractory bricks have a certain thermal conductivity. After actual measurement, the ceramsite kiln using such refractory bricks has a temperature of more than 450℃ on the outer wall at a position 1m close to the discharge port. Even at the feed port which is dozens of meters away from the discharge port, the temperature of the outer wall of the ceramsite kiln exceeds 200℃, and the heat loss is very high.

[0003] The utility model patent application document with publication number "CN202284909U" discloses a new type of refractory brick, including a refractory brick body; the refractory brick body is provided with two grooves in the width direction of the bottom surface, and the grooves run through the front and rear sides thereof. The refractory brick of this technical solution has grooves on its bottom surface, which reduces the contact area with the expanded clay kiln body and reduces heat loss; at the same time, the grooves are provided in the width direction of the bottom surface of the refractory brick, which ensures the structural strength of the refractory brick and will not damage the structure of the upper surface of the refractory brick, so that the refractory brick can continue to withstand the friction and impact caused by the expanded clay.

[0004] The new refractory bricks disclosed in the above document have the following defects: the compressive strength of the refractory bricks is relatively low, and they do not have a good sound insulation structure, and their practicality is relatively low.

[0005] It can be seen from this that the existing new refractory bricks do not have a good compressive structure, and it is necessary to improve the existing deficiencies and provide a high-strength, wear-resistant, combined silicon carbide refractory brick. Utility Model Content
