Abstract

1000L grade warm isostatic pressing double-layer hot loading self-reinforcing working cylinder and manufacturing method, belong to the technical field of superhigh pressure container, including from inside to outside fixed inner layer working core cylinder, outer layer hot jacket cylinder body, cooling interlayer and heat preservation interlayer. The inner layer working core cylinder is processed by pressure self-reinforcing and is in interference fit with the outer layer hot jacket cylinder body. The inner layer working core cylinder and the outer layer hot jacket cylinder body are both made of 30CrNiMo high-strength alloy steel. The interference fit between the inner layer working core cylinder and the outer layer hot jacket cylinder body is 0.4-0.5mm. The appearance is regular and beautiful, the processing cycle is short, the cost is low, the working condition adaptability is strong, and the temperature control structure is well adapted.
