The steel industry always occupies an important part in national economy of China, and the problem of high energy consumption of steel plants is gradually exposed. In order to resist such a severe competitive situation, the sintering plant needs to improve the yield and quality on one hand and reduce the energy consumption on the other hand, so that optimizing the sintering process is of great significance to the development of the steel industry.
In the metallurgical sintering production process, a sintering machine is the most basic mechanical equipment in the whole sintering process, and the main component of the sintering machine is a sintering belt consisting of trolleys. In the sintering process, the phenomena of air leakage inevitably occur among a head and tail sealing device, a trolley and a trolley of the sintering machine and among fan pipelines, the air leakage is harmful and beneficial to sintering production, the negative pressure intensity of a system can be reduced, and the quality of sintered ores is reduced. Therefore, how to strengthen the sealing device of the sintering machine and reduce the problem of air leakage in the operation process becomes a problem of important attention in the whole industry.
The contact between the existing sintering trolley and the trolley is the hard surface-to-surface contact, and the sintering temperature can reach more than 1300 ℃ at most in the sintering process. The sintering trolley can not avoid the deformation of the trolley caused by the phenomenon of expansion with heat and contraction with cold, and the phenomenon of generating a gap after the contact surface of the trolley and the trolley is deformed. In the sintering process, under the air draft effect of a main sintering exhaust fan, air is sucked from a contact gap between a sintering trolley and a trolley to cause serious air leakage, so that the cooling speed of edge sinter is accelerated, the ore return rate is increased, the strength of the sinter is reduced, and the quality of the sinter is reduced.
