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It is being lowered into the hole after drilling has reached total depth and the drill string withdrawn.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.

Micaceous Iron Oxide Powder is used for the manufacturing of cutting electrodes and has many distinct features like reflecting UV light, resistance of chemicals, long shelf life.
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 1200°C to 1250°C with a boiling point of 2355°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.
Ferro Silicon is an atomised alloy, which is formed by combining iron and silicon with a silicon content range of 15% to 90%. Ferro Silicon is a universal “heat-blocker” used in the production of carbon and stainless steels.

Relatively easy to change while the furnace is hot
Ferro Silicon used quartz(or silica)as raw material is made by electric furnace, because silicon and oxygen are easily
compound into SiO2, the Ferro Silicon is often used as deoxidizer in steeling. It also can be used as a suspended phase in the mineral processing industry and coating for welding electrodes in the electrode manufacturing. According to the content of Silicon, this product can be divided into FeSi with the Si content
Application :
1. Ferrosilicon is often used as deoxidizer in steel- making.
2. Ferrosilicon also can be used as alloy elements join agent, which is widely used in low alloy steel, non-ferrous metal, bearing steel, heat-resistant steels and electrician silicon-steel.
3. It can be used as a reductant in ferroalloy production and chemical industry.
4. In iron industry it can be used as inoculant and nodulizer.
Silicon Metal processed by excellent industrial silicon and including full varieties. Used in electro, metallurgy and chemical industry. It is silver gray or dark gray powder with metallic luster, which be of high melting point, good heat resistance, high resistivity and superior oxidation resistance, it's called "industrial glutamate", which is an essential basic raw material in hi-tech industry.
Silicon calcium is composed of the elements of silicon, calcium and iron, is an ideal compound deoxidizer, desulfurization agent. It is widely used in high quality steel, low carbon steel, stainless steel production and nickel base alloy, titanium alloy and other special alloy production.
In cast iron production,the calcium silicon alloy have inoculation effect.helped to form fine grained or spheroidal graphite; in the grey cast iron Graphite distribution uniformity,reduce chilling tendency,and can increase silicon,desulfurization,improve the quality of cast iron.
