In summer, the temperature is extremely hot and dry, and the brick factory is also operating at high temperature. Safety is especially important in this season. So there are many things to watch out for. Guangzhou Wanxin Pipe Industry Co., Ltd., a professional producer and seller of Dutch bricks, will tell you the matters needing attention in the summer brick factory production needs.
1. Material processing is a very important link in production, and it is the basis of production. It is a key process that is related to the quality of the molding, the value of the molding output, and the amount of electricity consumed. After the material is processed, not only can the molding process proceed smoothly, the wet appearance of the appearance and content of the output meet the requirements of the next process, but also conducive to the monotony and firing of the body.
During material processing, the particle size of the broken material, the gradation of the broken particles, and the moisture content of the material are the targets that must be controlled during the production process. For the particle size of the material, the maximum particle size cannot be greater than 2mm. It is assumed that the particle size of the largest particle in the material after crushing is larger than 2mm, and when the quantity is large, the surface and internal functions of the particle are different. It has a great impact, making the mud strips extruded by the brick extruder inconsistent in the function across the ground. Some local densities are high and some local densities are low. In severe cases, the particles of the material are larger, and when the proportion of large particles is larger, it is different from that of brick The large friction resistance on the wall of the mud cylinder makes it difficult for the extruder to extrude, it is difficult to form, and the power consumption of the production increases.
2. After the material is broken and damaged in the molding process, the future materials will be processed. Its maximum particle size and particle gradation meet the molding requirements. Whether high-quality wet billets can be formed depends not only on the function of the extruder, but also on the quality of the material. Moisture content.
When the moisture content of the material is too low, many difficulties are brought to the molding. The first is to reduce the quality of the molded body; the second is to significantly increase the energy consumption of the equipment and increase the degree of wear of the equipment; the third is that it may cause great damage to the equipment; the fourth is that the equipment cannot form a body that meets the requirements, maybe it is Can be molded, but the output value is extremely low. When the moisture content of the material is too high, the molding also has certain disadvantages.
3. The body is monotonous, whether it is natural or artificial monotony, the purpose is to remove the molding moisture in the body, so that it can reach the request of firing. When draining, on the one hand, the water in the green body should be drained to the extent that the green body can be fired, and on the other hand, it should be ensured that the green body cannot crack monotonously. At the end of the drainage, it is assumed that the remaining water content of the green body reaches 6%. The following can satisfy the burning request. The rate of monotonic dehydration and the moisture content of the body. The temperature, humidity, flow rate, and monotonic time of the heat medium are all greatly related. The higher the temperature of the heating medium, the stronger the dehydration ability, and the simpler the removal of moisture from the body, the more monotonous it is.
The higher the temperature of the medium is, the higher the moisture content is, and the closer it is to fullness, the worse the dehydration ability of the green body is, which is not conducive to the monotonic dehydration of the green body. The faster the flow rate of the heat medium, the larger the inductive heat transfer coefficient between the medium and the green body, and the larger the heat exchange capacity. The more heat is absorbed by the green body, the more water is evaporated in a unit time, and the more the water is discharged from the wet green body.
4. The firing process of the sintered body in the kiln is the process of the heat transfer of fuel and the chemical reaction, which is the basic principle of sintering of the body. When the kiln is fired, it is assumed that the higher the temperature outside the kiln, the lower the temperature difference between the kiln and the kiln, the smaller the heat loss of the kiln, and the less fuel required during firing.
In summer, attention should be paid to the participation of fuel in the kiln during the firing time. Assume that the bricks are burned in the entire area, and the fuel is added when the material is damaged. At this time, it should be smaller than the amount involved in the spring and autumn seasons. In this way, the heat required for the burning of the green body and the fuel transfer can be maintained. The heat is consistent, and there will be no overfire bricks (coke bricks), and no underfire bricks will be produced.
