Innovation of Φ102 mm CPE Push Bench Plant and Effectiveness

Presented here in the paper are the main aspects of the first domestic Φ102 mm CPE push bench plant located in Jiangsu Changbao Steel Pipe Co., Ltd., covering the features, construction background and current development situation, and the technical modifications as made since the start-up of the plant, including pass development of the push bench proper and the stretch reducing mill, expansion of the product mix, improvement of the tools & dies, R & D of new product and enhancement of the technological capability of the production line as a whole. The operation practice of the plant demonstrates that as a technology introduced from abroad, the CPE process is applied successfully in the country, and as a continuous rolling process for seamless steel tubes, it is proven and reliable. The CPE process has such advantages as low investment, technologically simplicity and being particularly suitable for making small-sized, light-wall hot-rolled tubes.
