Spray gun elbow sequence response region decomposition method based on lime powder balling matched with closed pulverized coal conveying process

The invention discloses a method for decomposing a sequence response area of a spray gun elbow based on a lime powder balling matched closed pulverized coal conveying process, which comprises the following steps: setting a plurality of areas on an arc part according to the variable-diameter bending requirement by using a variable-diameter fastening groove of an operating platform, a sliding clamp group and a low-speed electric chain hoist, and decomposing the arc part of the operating platform into areas I, II, III, IV...; the number of data points contained in each sub-area is 100, the tighter the radius number of the arc is, the more accurate the bending of the size of the bent pipe workpiece is, and the closer the size required by a solid body is. The method comprises the following steps: setting a sample radius library of RI, RRI... according to the precision and the bent pipe reducing requirement of a bent pipe workpiece, importing the sample radius library into a general formula of the arithmetic progre
