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.
The silicon carbide(sic) heating element is a kind of non~metal high temperature electric heating element. It is made of selected super quality green silicon carbide as main material , which is made into blank, solid under high temperature and re~crystallized. Compared with metal electric heating element, this element is characterized by high~applied temperature , anti~oxidization, anti~corrosion, long service life, little deformation, easy installation and maintenance. Therefore , it is widely used in various high temperature electric furnaces and other electric heating devices, such as in the Industries of magnet, ceramics, powder metallurgy, glass, metallurgy and machinery etc. All the specifications can be made according to your requirements. And our technical engineers are pleased to assist you! There are ed(rod) type?u type?w(three phase)type?g(gun)type?db(dumbbell)type?scr(double spiral)type?sc(single spiral)type?h type for you to choose.

Product introduction: Calcium is a silvery white metal that is harder and heavier than lithium, sodium, and potassium; It melts at 815 C. The chemical nature of metallic calcium is very active. In the air, calcium is quickly oxidized and masked with an oxide film. When heated, calcium will burn and emit a beautiful glow of brick red. Calcium and cold water have a slower effect, and intense chemical reactions occur in hot water to release hydrogen (lithium, sodium, and potassium can cause intense chemical reactions even in cold water). Calcium is also easily combined with halogens, sulfur, nitrogen, and the like. 1,product name:calcium metal 2,Shape :powder, lump and granulates 3,CAS:7440-70-2 4,Density:1.54g/cm 5,Melting point:850C 6,Boiling point:1440 C(lit.) 7,Application:Wheel keel Product use: At present, in the steel industry, the main use of metal calcium is to process into metal calcium particles, and then to make calcium iron wire or pure calcium wire, and finally used for steel refining outside the furnace, its role is to desulfurization, deoxidation, increase the fluidity of molten steel. Promote the rapid rise of inclusions in molten steel, generally used in the production of high-quality steel; as a dehydrating agent to produce anhydrous alcohol; in the petroleum industry, as a desulfurizing agent, in the metallurgical industry, it is used to deoxidize or desulfurize . However, calcium compounds have a very wide range of uses, especially in the construction industry.
