Abstract

PURPOSE:To enhance the corrosion resistance and the wear resistance of an exclusive liner for barrel by a method wherein rigid cases are formed on the inner surfaces of a pair of tubular liner base materials for single screw and, after that, a part of the peripheral side surface of each base material is cut off axially, and finally the cut-off surfaces of a pair of liner base materials are butt-welded to each other. CONSTITUTION:Cases 12, which are harder than liner base material or made of material such as Co-based alloy excellent in wear resistance, heat resistance and corrosion resistance or the like, are formed on the inner surfaces of a pair of the liner base material 11, which are made of austenitic stainless steel and have outer diameters and lengths corresponding to the inner diameter and length of the barrel main body of a twin-screw extruder. Next, the liner base materials 11 are fixed with jigs 20 and, after that, parts of the peripheral side surfaces of the fixed base materials are axially cut off by the same predetermined dimension, and the cut-off surfaces of a pair of liner base materials are abutted against each other. The abutted portions are welded together with electron beams 45 under the state that the depth W of welds of the welded portions 60 does not reach the cases 12 in order to obtain a twin-screw liner for protecting the inner surface of the twin-screw barrel.
