Gray cast iron is still the most used material for the production of castings. It can be made in several ways, but the most efficient and economical way to make gray cast iron is in a cupola furnace. A by-product in its production is slag, which arises from impurities that may be present in the charge, from coke, which is used as fuel for the cupola furnace and part of it also passes into the slag, from the lining of the cupola furnace as well as from oxides formed during of the smelting process, sulfides and phos...

Austempered Ductile Iron (ADI) is a promising material whose structure is obtained by isothermal processing, i.e. isothermal decomposition of austenite in the bainitic range. It is used in various industrial fields. It is characterized by an excellent combination of tensile strength and ductility, exceeding the properties of quenched and tempered steels in the strength range of 800 - 1500 MPa. Its production is problematic because the ferritic or ferritic-pearlitic ductile iron (SGI), which is the basis for the pr...

Briquetting is the pressing of dusty materials into pieces of the same shape and size. Briquetting can be done without a binder or with the addition of a binder to the briquetting mixture. Briquettes can have any shape, but the most common is the shape of a cylinder. The briquettes must be strong enough to eliminate the possibility of damage during transport and must be strong enough even at high temperatures. The briquettes have a regular shape, have the same weight, are more durable and easier to transport. They...

Cast iron GG30 (EN-GJL-300C) has excellent mechanical properties and good machinability. It can be used in many industries such as hydraulics, engineering, automotive, oil and gas mining, and processing. It is suitable for the production of compressor and pump components. Return material, technological residue, iron scrap, fractional cast iron, liquid metal, and alloying components can be used as input raw materials in the production of cast iron, the first three were taken into account in the analysis. In practic...
