A device fitted with a hinged collar and bowsprings to keep the casing or liner in the center of the wellbore to help ensure efficient placement of a cement sheath around the casing string. It is being lowered into the hole after drilling has reached total depth and the drill string withdrawn. This allows the casing string to be cemented to the borehole without any 'thin' cement areas.

Ferrosilicon is used as a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys. Ferrosilicon is also used for manufacture of silicon, corrosion-resistant and high-temperature-resistant ferrous silicon alloys, and silicon steel for electromotors and transformer cores.

Ferro Silicon Ferro Silicon has a melting point of 1200Ã?Â°C to 1250Ã?Â°C with a boiling point of 2355Ã?Â°C and Ferro Silicon contains about 2% of calcium and alluminium. Ferro Silicon, as an additive to the production process of ferrous metals, will impart several desirable properties upon the resultant alloy. Some of the primary benefits of adding Ferro Silicon to an alloy is to improve the corrosion resistant properties of the new compound, as well as to add to the high temperature heat- resistance properties of the new alloy, for example, in the production of silicon steel for use in transformer cores.
We are exporter of Ferro Silicon. FerroChrome is a kind of Ferro alloy which is formed by Ferro and Chrome,it is an important alloy addition in steel making. Ferrochrome (Fe Cr) is an alloy of chromium and containing between 50% and 70% chromium.
High-purity silicon metal is used by many industries. In the chemical industry it is used for producing silicon compounds as well as silicon wafers used in photovoltaic solar cells and electronic semiconductors. And aluminum manufacturers use it to improve the already useful properties of aluminum. When used with aluminum, silicon improves its castability, hardness and strength. Besides, aluminum demand has been growing steadily in recent years, as a reflection of the economic activity in both the developed and developing word. This demand of lighter and more economical material has triggered a growth in Silicon metal consumption by aluminum manufacturers. That said, silicon compounds are the raw material for a large and growing number of industrial and consumer products such as: Silicone rubber parts Urethane foam Sealants Adhesives Lubricants Food additives Coatings Polishes and cosmetics
After refining silicon slag is left over from the original silicon ore, but also contains a lot of silicon, silicon slag as one of production enterprises large number of procurement of metallurgical materials, has an irreplaceable advantage, because the purpose of the silicon is different, there are many different kinds of silicon slag and slag can be roughly divided into industrial silicon, solar silicon slag, semiconductor silicon slag, etc.Silicon slag itself has high utilization value and can be recycled or used as deoxidizer The application 1. Silicon slag can be used as a substitute for silicon metal. 2. The added amount of silicon used in blast furnace and cupola is 30%~50%, and the added amount of deoxidized silicon used in steelmaking is 50%~70%. 3. The silicon briquette produced with silicon slag has a broad application prospect in the foreign market. 4. Silicon slag is a good substitute for ferrosilicon in steelmaking, which has the advantage of reducing production cost Product Paramenters silicon slag Grade Si Ca S P C Ã¢?Â¥ Ã¢?Â¤ silicon slag 45 45 5 0.1 0.05 5 silicon slag 50 50 5 0.1 0.05 5 silicon slag 55 55 5 0.1 0.05 5 silicon slag 60 60 4 0.1 0.05 5 silicon slag 65 65 4 0.1 0.05 5 silicon slag70 70 3 0.1 0.05 3.5
