Tin

MOQ: Not Specified
Supplier From Navi Mumbai, Maharashtra, India
 
We are able to supply Tin in many forms including LME registered and
non registered, ingots, slabs, bars, foil, granules, powder, anodized
activated powder, shot, wire, sticks, ingots, and “mossy tin”.
Tin is a silvery-white metal, is malleable, somewhat ductile, and has a highly crystalline
structure. The element has two colours, with a cubic structure which changes at
allotropic forms. On warming it is grey, the ordinary form of the metal. When Tin is
cooled below 13.2°C, it changes slowly from white to grey or tetragonal structure. This
change is affected by impurities such as Aluminium and Zinc, and can be prevented
by small additions of Antimony or Bismuth.

Product Name: Ferrous Sulphate Heptahydrate
Molecular Formula: FeSO4. 7H2O
CAS No.: 7782-63-0
Mol Weight: 278.05

Usage and Dosage:
1. Industrially: ferrous sulphate heptahydrate is mainly used as a precursor to other iron compounds. It is a reducing agent, for the reduction of chromate in cement.
2. Nutritional Supplement: Together with other iron compounds, ferrous sulphate is used to fortify foods and treat iron-deficiency anemia. Constipation is a frequent and uncomfortable side effect associated with the administration of oral supplements. Stool softeners often are prescribed to prevent constipation.
3. Colorant: Ferrous sulphate can also be used to stain concete and some limestones and sandstones a yellowish rust color.
4. Water Treatment: Ferrous sulphate has been applied for the purification of water by flocculation and for phosphate removal in municipal and industrial sewage treatment plants to prevent eutrophication of surface water bodies.

Storage:
Storage Store in cool, dry, well ventilated area, removed from oxidising agents (eg. hypochlorites), acids, metals and foodstuffs. Ensure containers are adequately labelled, protected from physical damage and sealed when not in use. Large storage areas should have appropriate ventilation systems.

About THE Product :
Blast furnace slag is used in the production of cement (iron Portland and blast furnace cement).
Air-cooled blast furnace slag is formed by allowing the molten slag to cool relatively slowly under ambient conditions; final cooling can be accelerated with a water spray. The cooled material is hard and dense, although it can have a vesicular texture with closed pores. After crushing and screening, air-cooled slag can be used in several applications.
Granulated slag is formed by quenching molten slag in water to form sand-sized particles of glass. The disordered structure of this glass gives the material moderate hydraulic cementitious properties when very finely ground into granulated blast furnace slag, but if it can access free lime, the granulated blast furnace slag develops strong hydraulic cementitious properties.
Pelletized or expanded slag is cooled through a water jet, which leads to rapid steam generation and the development of innumerable vesicles within the slag. The vesicular texture reduces the overall density of the slag and allows for good mechanical binding with hydraulic cement paste.
Blast Furance Slag is a nonmetallic co-product which is produced in the process of iron manufacturing, Granulated Blast Furnace Slag is a glassy granular material formed when molten blast furnace slag is rapidly cooled by direct water.
Rapid cooling prohibits the formation of crystals and forms glassy, non-metallic, silicates and alumino silicates of calcium.

Hardened and Tempered Steel Strip
Hardened and Tempered is a thermal process that strengthens steel strips through a controlled heating and cooling process. The hardening process involves heating the steel strip to above the rapidly cooling. The steel strip in this condition is extremely brittle and requires further treatment in the tempering. Then strips are reheated to a lower temperature and holding it at the given temperature for a given period of time. This process is done in an inert atmosphere to avoid oxidation. This type of steel strip has big degree of toughness and has excellent spring properties
