Fast has been awarded "China's Most Influential Top 10 Parts Enterprise"


On March 4, 2014, during the 30th anniversary celebration and selection of the “China Automotive Industry Yearbook” held recently, Fast was awarded the “Most Influential China” by virtue of its industry's superior position and impressive operating results. Large parts companies" title. At the same time, two new products, “16-speed heavy-duty transmissions” and “6DS-dedicated transmissions” independently designed and developed by Fast, were selected as “China’s most influential automotive products” list.

The China Automotive Industry Yearbook, co-editored by the China Automotive Technology and Research Center and the China Association of Automobile Manufacturers, was founded in 1983. It integrates history, continuity and comprehensiveness. It not only witnessed the glorious history of the Chinese automobile industry for nearly 30 years. It also records the historical changes and development paths of China's auto industry in the past 30 years. It is the most authoritative and influential encyclopedia of China's auto industry.


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%.
