ABOUT FACTORY:

EXPERIENCE: The factory located in the southern China since 1999.It has several operations in Fujian Province.

EXCLUSIVE:Owns exclusive rights of high quality quartz mines in the region, and has several submerged-arc electric furnaces in production.  

ENVIRONMENT:The primary production sites are located in southern Fujian,where hydraulic power is abundant, and high grade of coal copious,key factors for cost effective silicon metal production.  

 CERTIFICATE:

The factory boasts an award winning pollution control systems that capture >99% of the dust generated from furnaces. We are a leader in environmental protection in the business sector of silicon metal production.

It is certified with ISO9001. It currently has 326 employees.  Many workers are specially trained in metallurgical engineering, mechanical or electrical engineering, analytical chemistry, or business management. 99.99 silicon powder

In Dec 2010, Factory has successfully completed REACH (Registration, Evaluation,Authorization and Restriction of Chemicals, Regulation of EC). As more than half production is exported, the REACH registration is expected to help us expand our presence in the European markets.

 

 

RAW MATERIAL PROCESS:

 

PRODUCTION OF SILICON METAL:

 Preparing si powder 99% purity

1.The raw materials(silicon dioxide,carbon materials) are weighed and then placed into the furnace through the top using the fume hood.

 2.The lid of furnace,which contains electrodes,is placed into position.

Melting si powder 99% purity

3.Electric current is passed through the electrodes to form an arc.The heat generated by this arc melts the material and results in the reactin of sand with carbon to form silicon and carbon monoxide.

Reducing si powder 99% purity

4.While the metal is in the molten state,it is treated with oxygen and air to reduce the amount of calcium and aluminium impurities.Depending on the grade,silicon metal contains 98.5-99.99%silicon with trace amounts of iron,calcium and aluminium.

Cooling si powder 99% purity

5.The silicon is then tapped from the bottom of the furnace and cooled in large cast iron trays.

Crushing si powder 99% purity

6.After cooling,the metal is dumped from the mold into a truck,weighed and then dumped in the storage pile.Dumping the metal from the mold to the truck breaks it up sufficiently for storage.

Packaging

7.Silicon metal is usually packaged in large sacks or wooden boxes.In powder form,silicon is packaged in plastic pails or paper bags.
