On October 10, the world's Z-sized 18500-ton oil press completed the "big test" in Luoyang and successfully forged 438-ton super-large steel ingots. It indicates that the forging capacity of China's large free forgings has reached the world's advanced level, which will effectively alleviate the urgent need for large forgings in China's electric power, petrochemical, metallurgy, mining, building materials, shipbuilding, aerospace and other fields. it is of great strategic significance to comprehensively enhance the industrial image and ability of China's high-end equipment manufacturing.

At 10: 00 a.m., in the heavy forging department of citic heavy industries, the 18500-ton free forging oil press was linked with the 750-ton-meter manipulator, which completed the upsetting of 400-ton steel ingots in only 2 minutes. The 438-ton steel ingots were repeatedly forged like kneading dough. Onlookers could still feel the heat wave from more than 10 meters away. It took 1 hour before and after, and the upsetting and drawing process of 438 tons of steel ingots was successfully completed.

The forging equipment unit for CITIC Heavy Industries and Germany WEPUKO in a joint design, joint manufacturing, joint brand way, specifications and power are the world's Z. The forging equipment unit is linked with the 750-ton-meter forging operator to form a highly automated heavy-duty free forging platform. The positive and negative errors of forgings are not more than 2mm. Forging a forging can perform 10 actions at the same time, and one person can complete the operation. In addition, its hydraulic transmission system adopts pump control technology, which greatly reduces energy loss compared with traditional valve control and achieves more than 20% energy saving effect. The whole set of equipment has the characteristics of large forging space, high forging precision, low energy consumption and high degree of automation.

It is understood that since it entered trial production in March, the 18500-ton free forging oil press has successfully completed the forging task of more than 110 steel ingots of 100-300 tons, successfully realized the forming and size control of shaft, plate, cake, ring and other products, has the ability to produce large forgings, and was officially put into production on June 29. The 438-ton super-large steel ingot successfully forged this time is a large key forging provided by citic heavy industries for Jiangyin xingcheng special steel 4300 mill. it is smelted by double vacuum, and the internal quality requirements are implemented according to the DANIELI standards of famous foreign enterprises.
