description The invention discloses an automatically-controlled constant-pressure strip making method. According to the method, a sealed nozzle package is used for containing alloy liquid, and the alloy liquid issprayed onto the surface of a cooling roller which is rapidly rotating through a nozzle under the nozzle package, and a solid alloy strip is formed; inert gas is introduced into the nozzle package inthe strip spraying process, the pressure of the inert gas is used for compensating the hydraulic pressure drop caused by the liquid level drop of the alloy liquid during strip making, the compensation air pressure value is automatically calculated and controlled in real time by a center console according to a compensation gas pressure change equation according to the strip spraying process parameters, and the pressure of the alloy liquid sprayed from the nozzle is kept constant in the entire strip making process. The center console also realizes the real-time and automatic control over the process parameters, such as
