Colloidal Silica Sol 30% For Investment Casting

This Cast Iron slag is a by-product derived from the production of thermal insulating products. The byproduct is a ferrous slag which can be utilised in an electric arc furnace to produce crude steel. Physical Description On visual inspection, it appears to be made up of irregular shapes. Dimension: 500mm -800mm Chemical Composition Its chemical composition is homogeneous and stable with Fe contents in the range of 90 +/- 5% and P contents < 0.6% S around 0.15% and C% around 3.5%. Packing: Loose in container Loading: in 20 Container For further information, please feel free to contact us.

For sale: Refine Silica sand from Indonesia with purity 99.5% up, stock available 100k mt per month.

We are glad to propose 500 MT of stain less steel mill scale. Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products. At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel. The recovery ratio after melting in furnace for the most valuable alloy elements is: - Ni: 3.5 - 4.5% - Cr: 6-8% From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows: Waste code: 10 02 10 The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers. Chemical analysis of the material is available on request.

We are proposing about 2000tons of iron slag derived from the desulphurisation skimming process. This material is a iron by- product that is encapsulated in varying levels of contaminants (S,Mg,Si). In order to enhance its usability, the material is processed and screened. We can propose two specifications of Iron Slag - European Code: 19.12.01 - Basel Code: B1010 - HS Code: 2619.0020 - Quantity: 2000 tons currently available - Monthly quantity: 500-1000 tons depending on production - Size: 350 1200 mm - Fe content: from 77 to 86% - C content: above 2,5-3% - Bulk density: 2,8-3,4 tons/m3 - Loading type: loose in 20 (26-27 tons on average) The level of Fe% in the slag has been estimated by water displacement test.

Mill scale, is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling hot iron or steel billets in rolling or steel mills. It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color. Being produced during the reheating, conditioning and hot rolling operation for the production of steel articles, the mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating. From the chemical and physical analysis performed on the scrap, and according to the european environmental rules, the material has been classified as a special non dangerous waste, listed in green list In particular the mill scale can be classified as follows: Einecs (european commission no.): 266-007-8 Waste code: 10 02 10 Basel code: b 12 30 Hs code: 2619.00

We are proposing about 1000 1200 Mt/ton monthly of iron slag derived from the desulphurisation skimming process. This material is a iron by- product that is encapsulated in varying levels of contaminants (S,Mg,Si). In order to enhance its usability, the material is processed and screened. We can propose two specifications of Iron Slag : 1. >85% Fe Average 600mm Max Fraction 2. >78% Fe Average 20-300mm Fraction The level of Fe% in the slag has been estimated by water displacement test.

Desulphurisation Slag is an iron slag derived from the desulphurisation skimming process. This material is an iron by- product that is encapsulated in varying levels of contaminants (S,Mg,Si), but has a stable chemistry with 75 -80% chemistry. The level of Fe% in the slag has been estimated by water displacement test. This material con offer competitive advantages respect other metal scraps: Price; Stable Chemistry; The material can be loaded loose in 20 heavy duty container. For further details feel free to contact us.

Micro Silica Sand: Micro silica also known as fume, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 mm. The main field of application is as pozzolanic for high performance concrete because of its extreme fineness and high silica. Applications : Silica is added to Portland cement concrete to improve its properties, in particular its compressive strength, bond strength, and abrasion resistance. These improvements stem from both the mechanical improvements resulting from addition of a very fine powder to the cement paste mix as well as from the pozzolanic reactions between the silica fume and free calcium hydroxide in the paste. Advantages : Addition of silica also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways and runways (because of the use of deicing salts) and saltwater bridges.
