Environmental protection requirements of the casting process

Casting production is a forming process from smelting metal, manufacturing molds, pouring molten metal into molds, and solidifying to obtain metal part blanks with a certain shape, size and performance. During this process, solid, gas waste and harmful gas will be discharged.

Casting process: the effect of five major elements on the structure and properties of gray cast iron

The five major elements in cast iron are carbon, silicon, manganese, sulfur, and phosphorus. Carbon and silicon are the two main chemical elements in ordinary gray cast iron.They have a decisive influence on the structure and properties of cast iron. In production, it is often controlled by controlling and adjusting the content of carbon and silicon.

Intuitive identification method for steel

Approximate carbon content. The steel with low carbon content has fine grains in cross section and its color is grayish white; the steel with high carbon content has slightly coarse grains in cross section and its color is white. The fracture of alloy steel is generally fine. The section of high-speed steel has finer grains and broken fine porcelain

How many kinds of cast iron are there? How to indicate the grade?

Cast iron is an iron-carbon alloy with a carbon content of more than 2.11% (typically 2.5-4%). It is a multi-component alloy with iron, carbon, and silicon as the main constituent elements and containing more impurities such as manganese, sulfur, and phosphorus than carbon steel. Sometimes to improve the mechanical properties of cast iron
