20 kg of rare and wild seeds appeared in the "Asia-Europe Expo"

20 pounds rare and hetian jade appeared at the "Asia-Europe Expo" to introduce the concept of diesel generator | diesel generator price / 2012-09-07

Urumqi, September 7th, September 6th, reporters at the "China-Europe Expo" saw a 20-pound Xinjiang Hetian white jade seed material in the display, warm jade and "big head" attracted enthusiasts onlookers .
It is understood that Hetian jade is divided into mountains, mountains, water, seed jade, which is a good jade seed jade, seed jade head is generally very small, mostly below 100 grams, 20 kg seed jade rare, It is rarer that jade is delicate and moist white jade seed material.
This piece of 20 pounds of Hetian seed jade, on the surface there is a layer of yellow jade, called "Sakyhpi", it is understood that Hetian seed jade is hiding in the Yulong River in Xinjiang Hetian, its surface will generate a variety of The color is known as the "Zihongpi", "Saggingpi", "Qiupi Peel" and so on.
In the era of high-quality Hotan seed jade sold in grams, people could not help but be curious about the price of the seed jade, but the owner of the seed jade said, “This piece of jade has been “going ashore” from the river for several years and has not been sold. I did not participate in auctions either because I liked it and I was reluctant to sell it. This time, the China-European-European Expo was not meant to sell it.

Foundry Furnace Charge (ferro Sulphur)-ZLJ

Ferro sulphur is generally used for increasing the sulfur content of gray pig iron or molten iron, too low sulfur in gray pig iron is harmful: poor inoculation effect, poor graphite shape and poor cutting performance.


Suitable range: 0.07%-0.12%. Sulfur makes the length of graphite shorter, the end becomes blunt, the shape becomes curved, and the mechanical properties are improved in the range. Resulfurization is required when the sulphur content is less than 0.05%.

Usage of ferro sulphur:after a small amount of iron is added in the electric furnace during the production of electric furnace, the ferro sulphur with a particle size of 8-25mm is added to the furnace according to the demand of sulfur, the ferro sulphur is pressed by adding iron, and they are smelted. The absorption rate is above 99%.

Advantages of ferro sulphur: the high efficient ferro sulphur for casting gray iron produced by our company can be used conveniently, safely and reliably with few impurities and high absorption rate up to 95%. Sulfur can be added to gray pig iron for improving the cutting performance, and improving the inoculation effect and graphite shape. Because sulfur can make the length of graphite shorter, the end becomes blunt, the shape is curved, and the mechanical properties of the gray pig iron are improved by resulfurization. It is beneficial to control the sulfur in gray pig iron within the range of 0.08%-0.12%.
