"Refractory brick manufacturing process" refers to the refractory brick manufacturing process and molecular structure. After years of practical activities and transformation, it has continuously changed the wall building method in the furnace, improved the power level, changed the secret recipe of concrete, reasonably solved the problems such as floating brick and salt leakage, and doubled the service life of the salt furnace. The third traditional method is used to build the wall with fire-resistant cement instead of ammonium sulfate concrete, but the surrounding fire-resistant cement is tamped with ammonium sulfate concrete instead. The secret recipe of ammonium sulfate concrete is as follows: 30% of high alumina cement clinker, 35% of particles of 3 ~ mm clay brick and 35% of particles of 10 ~ 14mm clay brick. These three raw materials are uniformly mixed after net gravity separation, which is commonly known as stone. It is called adhesive to mix more than 85% of industrial concentrated ammonium sulfate with water in the proportion of 1:2.

"Refractory brick manufacturing process" refers to the manufacturing process and molecular structure of refractory brick. After mixing the stone with adhesive, mix it every 2 ~ 3H. After being symmetrical, the plastic film on the cover plate can make plastic alcohol for 20 ~ 24 hours. The level of wet area can be kneaded by hand. It is best to have no sticky but wet and cold feeling. Then, it can be tamped and formed. In the whole process of tamping, wood formwork must be added in the furnace to fix it, and vibrating rod shall be used to vibrate and tamp it. In that way, ammonium sulfate and stone will produce AlPO4 inorganic polymer, which will screw the concrete into a whole, and improve the service life of the salt furnace. Dry for 3 months after tamping. If the application is in urgent need, of course, it must be dried for more than seven days, and then dried with firewood for seven days. Finally, when the temperature is above or below 700 ℃, the salt in the old salt furnace is scooped into the new furnace, and it can be used the next day. Avoid running water maintenance. Changing the wall building method of refractory bricks in the furnace is ineffective for the salt bath furnace, which is mainly due to the penetration of salt liquid into the brick joint, which makes the brick joint between refractory bricks expand, so that the salt liquid touches the furnace liner, resulting in short-circuit fault. As the laying method of bricks during wall building immediately endangers the size and direction of brick joints, it also immediately endangers the penetration speed of salt solution.
