The invention relates to a manufacturing technique of a cylinder barrel used in trains, which produces a centrifugal and endoergic crushing cylinder barrel by five processes of proportioning, smelting, centrifuging, isothermal annealing and post processing. The liquid metal is poured into a mold rotated by a centrifuge. The liquid metal is filled in the mold and is solidified for forming a new casting method under the effect of the centrifugal force. Under the same effect of the centrifugal force, an internal pore is naturally formed by a certain amount of molten steel through high speed running of the centrifugal. Furthermore, due to the effect of the centrifugal force, the material structure of the product is very compact. A specific heat treatment is adopted to resolve the contradiction existed between the high strength and the high tenacity, thus ensuring the coexistence between the high strength and high tenacity. When the product is used for emergently breaking a train with a high speed, the products can bear an impact force of more than 130 tons. Furthermore, the product plays buffering effect without occurring cracks, and the price of the home-produced centrifuged cylinderbarrel only accounts for 40 percent of the import price.
