These cast iron skulls are a by-product derived from the cast iron foundries. The byproduct is a ferrous by-product 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.
The material is separated by magnet and screener.
Packing: Loose in container
Loading: in 20 Container

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.
Pipe fittings are the general names of parts and components that play the role of connection, control, direction change, diversion, sealing and support in the pipeline system. Steel fittings are pressure fittings. According to the different processing technology, it is divided into four categories, namely, butt welding pipe fittings (divided into weld and no weld), socket welding and threaded pipe fittings, flange pipe fittings.
According to the application:
1. pipe fittings for connecting pipes are: flanges, live joints, pipe hoops, clamps, clamps, throat hoops, etc.
2. changing the direction of the pipe: bends, bends.
3. pipe fittings changing pipe diameter: variable diameter (different diameter pipe), different diameter elbow, branch pipe table, reinforcing pipe.
4. pipe fittings with additional piping branches: three links, four links.
5. pipe fittings for pipe sealing: gasket, raw material belt, thread, flange blind plate, pipe plug, blind plate, head, welding plug.
6. pipe fittings for pipe fixing: clasp, hook, ring, bracket, bracket, pipe clamp, etc.
According to the connection :1, welded pipe fittings 2, threaded pipe fittings 3, clamping pipe fittings 4, clamping pipe fittings 5, socket pipe fittings 6, rubber ring connection pipe fittings
According to the material divided into 1, cast steel pipe fittings 2, forged steel pipe fittings 3, alloy pipe fittings 4, stainless steel pipe fittings.
Pipe fittings are widely used in municipal, petrochemical, west-to-east gas transmission, ships and nuclear power.
The primary use of Ammonium Sulphate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of Ammonium Sulphate is its low nitrogen content relative to Ammonium Nitrate, which elevates transportation costs.
It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate and glufosinate herbicides.
