Mr. Zhou led a team of four to start Great Wall Foundry in Wuzhou, Guangxi, China. With a 200 kg furnace, the foundry started with
melting metal scraps into steel blocks and sold them to bigger steel
makers as melting material.
Observing the boom in China's economic reform, Great Wall Foundry started to produce manganese jaw liners up to 500 kgs that were popular among quarries in Guangdong province.
In order to increase its manufacturing capacity, Great Wall Foundry moved to a new location at Zhongshan, Guangxi, China. A
new foundry was built with four one-ton furnaces, and large jaw
liners up to 3 tons were made to meet the demand in the market.
After years of study and research, Great Wall Foundry perfected its techniques of "Clean Melt" and "Die Casting with Sand Layer". These
concepts are still the key characteristics of the parts the foundry manufactures. Especially when later new products with a higher
manganese content were developed, "Clean Melt" provided a great
advantage on the productions of castings with 21% and 25%
the "Clean Melt" and "Die Casting with Sand Layer" technique, Great
Wall Foundry successfully caught the attentions of some industrial
leaders in the crusher manufacturing. The foundry started to supply
OEM wear parts for partners of leading crusher manufacturers. Its
international sales team, MnSteels, was formed and began its first
step to the international market.
Guilin Liangjiang International Airport (KWL), us about 200kms from our foundry. Taking the high speed rail from Guangzhou to us (Zhongshanxi
Station) is about 2 and half hours, and from Guilin to us (Zhongshanxi
Station) is about 1 hour.
All castings go through a cooling phase which takes from 48 hours to 120 hours depending on the thickness of the castings. For example, our C200 plates are about 300 mm thick, so they have to cool down for at least 100 hours. Each casting has a process sheet which lists the related requirements, including cooling time.
Our main products are manganese crusher plates,
including cone crusher liners and jaw crusher liners.In addition to other manganese steel parts, we also manufacture high chrome cast iron and other alloys.
We use bottom pour ladle; the temperature is 1,420 degrees centigrade when pouring the
first product. Pouring temperature for the rest of the products from the same ladle is lower than 1,420
