Title:
SINTERING SYSTEM CAPABLE OF IMPROVING TEMPERATURE UNIFORMITY
Document Type and Number:
WIPO Patent Application WO/2023/160103
Kind Code:
A1
Abstract:
Disclosed in the present application is a sintering system capable of improving temperature uniformity. The sintering system comprises: a multi-layer and multi-column atmosphere furnace, a preheating unit with a two-stage structure, and lateral heating devices. In the sintering system, a two-stage preheating mode is used to heat a gas inputted into the atmosphere furnace, wherein the first-stage preheating not only plays a role in preheating, but can also cool materials to be discharged from the furnace, such that the gas consumption of the cooling section is saved on; and the second-stage preheating not only saves energy, but also improves the utilization rate of heat. The lateral heating devices can compensate for heat loss caused by heat transfer between the side and the outside, and solves the problem of insufficient heat at the side due to a high hearth, such that the uniformity and stability of the temperature in the hearth is improved. A ventilation mechanism can disperse intake air flow, such that the stability of the atmosphere is guaranteed, the uniformity of a temperature field can be greatly improved, and flying dust can also be avoided. By means of the two-stage preheating, the lateral heating devices and the ventilation mechanism on lateral air inlets, the uniformity of the internal temperature of the multi-layer and multi-column atmosphere furnace can be maintained, such that the product quality is improved.
