Steel ladle baking method based on micro negative pressure technology

The invention discloses a steel ladle baking method based on a micro-negative pressure technology, which comprises the following steps of: introducing converter gas into a ladle cover of a ladle baking device, and starting ladle baking; the booster fan is started, so that negative pressure is formed in the air inducing pipe; the opening degree of the automatic adjusting valve is adjusted so as to adjust the negative pressure in the air inducing pipe, and flames in the steel ladle can come out from the water opening; and after baking is finished, the booster fan is turned off. The problems that an existing steel ladle baking device is long in baking time, the baking efficiency of the outer wall and the bottom is different, and the heat utilization rate of converter gas is low are solved. 本发明公开了一种基于微负压技术的钢包烘烤方法，包括以下内容：将转炉煤气通入烤包器的包盖，启动烤包；启动增压风机，使得引风管内形成负压；调节自动调节阀的开度，以调节引风管内的负压大小，使得钢包内的火焰从水口窜出；烘烤完毕，关闭增压风机。其解决了现有钢包烘烤装置烘烤时间长、外壁、底部烘烤效率不一，使转炉煤气热利用率低的问题。
