[0002] Ignition is the most important link in the sintering process. In the prior art, when the sintering ignition furnace is used for ignition, the flame ejected from the burner is not rigid enough and the flame is uneven, which reduces the quality of the sintered ore. At the same time, due to the tightness of the ignition furnace Poor, resulting in more loss of heat energy, resulting in higher cost of the sintering process and low utilization rate of heat energy

Description
Technical field [0001] The invention belongs to the field of sintering technology, and relates to a sintering device, in particular to a sintering ignition furnace. Background technique [0002] Ignition is the most important part of the sintering process. In the prior art, when a sintering ignition furnace is used for ignition, the flame sprayed from the burner is not rigid enough and the flame is uneven, which reduces the quality of the sinter, and at the same time, due to the tightness of the ignition furnace Poor, resulting in more heat loss, leading to higher cost of this sintering process and low heat energy utilization. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a sintering ignition furnace which improves flame rigidity, improves the sealing performance of the ignition furnace and improves the utilization rate of heat energy. [0004] In order to achieve the above objective, the present invention provides the f...
