Hongrun nuclear equipment successfully completed the hot tire die extrusion forming of the million KW nuclear power stainless steel pump shell. On April 8, witnessed by 8 experts from China First Heavy Machinery Corporation, North China station, nuclear safety center, Shengu group, Shanghai Nuclear Engineering Institute and other units, Hebei Hongrun nuclear equipment Technology Co., Ltd. (hereinafter referred to as Hongrun nuclear equipment), an innovation leading enterprise in Hebei Province, once again demonstrated its power in the 50000 ton vertical extruder. On April 8, witnessed by 8 experts from China First Heavy Machinery Co., Ltd., North China railway station, nuclear safety center, Shengu group, Shanghai Nuclear Engineering Institute and other units, The 50000 ton vertical extruder of Hebei Hongrun nuclear equipment Technology Co., Ltd. (hereinafter referred to as Hongrun nuclear equipment) which is an innovation leading enterprise in Hebei Province, has shown its magic power again: after five years of investment in tooling and dies of 10million yuan, the million kilowatt nuclear power stainless steel main pump shell developed through scientific research and innovation has successfully completed the hot tire die extrusion of the million kilowatt nuclear power stainless steel pump shell on the basis of the original trial parts

the million KW nuclear power pump can bring greater economic benefits to the plant. The full compressive stress die forging of the shell is an advanced manufacturing, which will be another technological progress in the product quality of China's nuclear power main pump shell. The successful development of the million kilowatt nuclear power stainless steel die forged pump casing not only solves the international problem that the cast pump casing cannot meet the technical requirements, but also can replace the manufacturing technology of alloy steel forged pump casing plus inner wall surfacing stainless steel

"it is a disruptive innovation and epoch-making significance to adopt austenitic stainless steel forging and extrusion to replace the traditional cast shell for the main pump shell of nuclear power." Relevant experts are full of praise for the power of Hongrun super equipment. The pump casing of the nuclear main pump is known as the "heart part of the nuclear power plant". Its forging and extrusion technology is the upgrading technology of the original castings. Hongrun super equipment is the only equipment in the world that can extrude this product, which represents that the manufacturing technology of large forgings of nuclear power in China has reached the international leading level

with the help of 50000 tons, a super manufacturing brand of vertical extruder in the world with huge extrusion force and the largest opening size and working platform, Hongrun has revolutionized the one-time extrusion of complex pipeline products such as nuclear power main pump casing, nuclear 253044907020 main pipeline, inclined tee and valve body, making the service life of these key nuclear power products Reliability and economy have been improved to a new stage

in the view of many experts, Hongrun's super equipment can realize the extrusion forming of large-diameter seamless steel pipes and parts made of high alloy steel, heat-resistant steel and other difficult to form materials, and the die forging forming of forgings of various materials. If it is matched with special dies, it can also realize the internal high-pressure forming of special-shaped pipes. Hongrun's overall production line has formed a large forging and extrusion equipment group represented by a 50000 ton large hydraulic press, which, combined with other auxiliary equipment, has become an important base for the forging production of large-scale high-performance parts worldwide
