Industrial history！Do you know when was operating the first very large size open die press ever buil
Do you know when was operating the first very large size open die press ever built ? It was in 1929 in Krupp AG forgeshop in Essen (Germany). It was a 15,000-ton four columns push down hydraulic press, an unmatched forging unit at that period capable to forge steel ingots up to 300 tons ! We can see on the picture a mandrel forging operation with two overhead cranes to handle and turn the steel part. The only missing equipment with this amazing press forge is a large size rail bound manipulator (that were developed well afterwards) as we can see nowadays on such kind of large open die presses.
Chaeng (Xinxiang Great Wall Machinery Corporation) located at National Sustainable Development Experiment Area, Mengzhuang Town, Huixian City, Henan Province, China, was initially built in 1958 and restructured into limited liability Company from township collective enterprise in 2002.
Covering an area of 330,000 m² and having more than 1,100 employees, the company has a total asset of CNY 500 million and has passed ISO9001:2008 quality management system authentication and is a main specialized supplier for manufacturing large scale kiln mill. Possessing the experience of equipment manufacturing for more than half a century, the Company has formed the perfect operation and management system in design and development, product manufacturing, market promotion, equipment installation and after sales service.
The Company once won the honors of High Growth Private Enterprise of Henan Province, The Top 100 Suppliers of China’s Cement Industry in 2015, The Top 10 Innovative Enterprise of China’s Cement Industry in 2015 and so on.
In 2010, Xinxiang City Great Wall Machinery Co., Ltd. built the first environmentally friendly granulated slag powder demonstration production line in China's machinery industry with an annual output of 600,000 tons! Using many advanced technologies, it realizes the operation of environmental protection and high automation equipment!
In 2014, Xinxiang Great Wall Machinery Co., Ltd. designed and built an industrial waste residue with an annual output of 1.5 million tons in line with the powder production line for Ningbo Baosteel Co., Ltd. in Ningbo. This is also the country's first industrial waste residue composite powder production line.
In order to study the recycling of steel slag, GGBS (Ground Granulated Blast Furnace Slag) and waste slag from steel mill and solve the problem of steel mills zero emissions, Shanghai baosteel build this demonstration project of total utilization of steel slag composite powder in domestic This plays a leading role for the comprehensive utilization of steel slag , solves the secondary effects on the environment of steel factory solid waste, and improves the efficiency of the enterprise.
