Embodiment 1

[0027] A refractory furnace core, the furnace core is a round tube, the outer layer is an iron plate furnace barrel, and the inner layer is made of the following raw materials in mass percentage:

[0028] Refractory sand 35%, refractory powder 18%, refractory cement 25%, refractory mud 15%, water 7%.

[0029] Preparation method:

[0030] (1) Weigh each raw material according to the mass percentage, and stir evenly to obtain the mixed material;

[0031] (2) Apply the mixed material evenly on the inner wall of the iron furnace barrel, with a thickness of 2.0 cm;

[0032](3) After the coating is completed, let it stand for 5 minutes, wait for it to be formed, and clean the furnace core;

[0033] The clearing means that before the furnace core is completely solidified, the inner surface of the furnace core is repeatedly scraped with an ash scraper, and the fine sand particles are pressed in, and the mud emerges, so that the surface layer is "oily";

[0034] (4) After clearing t...

[0038] A refractory furnace core, the furnace core is a round tube, the outer layer is a metal furnace barrel, and the inner layer is made of the following raw materials in mass percentage:

[0039] Refractory sand 34%, refractory powder 17%, refractory cement 25%, refractory mud 16%, water 8%.

[0040] Preparation method:

[0041] (1) Weigh each raw material according to the mass percentage, and stir evenly to obtain the mixed material;

[0042] (2) Apply the mixed material evenly on the inner wall of the iron furnace barrel, with a thickness of 1.6 cm;

[0043] (3) After the coating is completed, let it stand for 6 minutes until it is formed, and then clean the furnace core;

[0044] The clearing means that before the furnace core is completely solidified, the inner surface of the furnace core is repeatedly scraped with an ash scraper, and the fine sand particles are pressed in, and the mud emerges, so that the surface layer is "oily";

[0045] (4) After clearing the ligh...

Abstract

The invention discloses a refractory stove core and a preparation method thereof. The refractory stove core is prepared from refractory sand, refractory powder, refractory cement and the like. The method comprises the steps of uniformly mixing and stirring the raw materials, then, uniformly coating a mixture on the internal wall of a plate iron stove barrel or sheet iron stove barrel, standing until a stove core is molded, then, polishing, finally, carrying out natural curing and watering curing, and then, naturally drying, thereby obtaining the refractory stove core. The stove core disclosed by the invention has very good fire resistance, strength and corrosion resistance, the probability of stove core crackling is reduced fundamentally, and the service life of the stove core is prolonged effectively; according to the refractory stove core disclosed by the invention, the refractoriness can reach above 1,700 DEG C, and the service life is longer than 3 years.

Description

technical field [0001] The invention relates to a refractory furnace core and a preparation method thereof. Background technique [0002] Furnace core is a replacement core for stoves such as coal stoves. It is widely used in Southwest China, especially in small and medium-sized towns and rural areas. It is used for heating, cooking, baking, etc., and is very important for the normal use of stoves. For example, briquette furnaces and iron coal furnaces must be equipped with refractory furnace cores; and the use of refractory furnace cores can avoid deformation of furnace cracks. Because the furnace core is often affected by the high temperature environment (combustion charge) during use, it will be damaged. With the extension of the use time, when the service life of the furnace core ends, the furnace core must be replaced to continue to use the stove. In order to prolong the service life of the furnace core and make the furnace core have high temperature resistance, refrac...
