Many small and medium-sized founders often ignore the effects of chemical composition on high manganese steel castings when doing high manganese steel. Molybdenum can inhibit the formation of carbonation and promote the formation of pearlite....

The process of blast furnace steelmaking is the process of deoxidizing and reducing iron oxides to metallic iron. Metallic iron is extracted from iron ore. The metallic iron in iron ore exists in the state of iron oxide. Therefore, extractin...

In the production of malleable iron castings, common casting defects include shrinkage cavity, shrinkage porosity, porosity, pores, cracks, sticky sand, rough casting surface, shrinkage, eccentricity, wrong shape, insufficient pouring......

Adding a certain amount of certain alloying elements to cast iron can obtain alloy cast iron with higher corrosion resistance in some media. High silicon cast iron is one of the most widely used....

Inclusions in castings mainly affect the fatigue strength, processing performance, and structural properties of the castings, and are also one of the reasons for casting cracks....

Gas injection stirring is a more extensive method of stirring ladle. Argon is the most common gas used to stir molten steel, and the use of argon depends on the type of steel being refined. Therefore, the blowing gas agitation is mainly vari...

The sticky sand defects on the surface of sand castings can be divided into mechanical sticky sand and chemical sticky sand. Mechanical sand sticking is caused by molten metal drilling into the pores between the sand grains of the sand mold...

In the production of gray iron castings, common casting defects are：pores, unqualified composition and performance, hot and cold cracks, shrinkage and porosity, slag holes and iron beans, insufficient cold insulation and pouring, trachoma and sand ....

Electric arc furnace is another steelmaking method after converter and open hearth. Because more than 95% of the worlds electric furnace steelmaking production is produced by electric arc furnaces, electric furnace steelmaking mainly refers...

Desulfurizer is a material that can generate insoluble or low-soluble sulfide in iron with the sulfur in the molten iron, thereby reducing the sulfur content of the molten iron. Hot metal desulfurizers can be divided into four categories: li...

The heat treatment process refers to the whole process of the heat treatment operation, including the formulation or heat treatment procedures, process control and quality assurance, process management, process equipment, etc....

Silicon barium calcium is a common additive in steelmaking, and silicon, barium calcium can form oxide impurities such as oxygen in the steel, often used as a deoxidizer. ...
