Rare earth ferroalloys make steel "better"

The addition of rare earth ferro alloys to steel can refine the steel grain size, alter inclusions, and improve low-temperature impact flexibility, strength, strong plasticity, and wear resistance.

Ferrophosphorus for steelmaking has great effect

Ferrophosphorus for steelmaking mainly increases the content of phosphorus in molten steel, and the steel produced has better cutting performance.

The difference between the content and use of green silicon carbide and black silicon carbideThe difference between the content and use of green silicon carbide and black silicon carbide

Green silicon carbide and black silicon carbide are two commonly used types of silicon carbide. The main difference between the two is the content of silicon carbide and the uses they are put to.

Differences in composition and use between ferromanganese and metallic manganese ingots

Manganese iron and metal manganese ingot are two important materials in steelmaking. Manganese iron usually contains about 75% to 80% manganese and 15% to 18% iron. It is mainly used as an additive in steelmaking to promote the deoxidation and desulfurization of steel, improve its mechanical properties, and prevent the formation of cracks during solidification.

Introduction and use of silicon slag

Silicon slag is widely used in steel mills and foundries, and can be used as high-quality raw materials for smelting cast iron and silicon manganese alloys; Silicon slag can well improve furnace temperature, increase the fluidity of molten iron, high-quality slag removal, and increase brand; Silicon slag can also be used as a deoxidizer in steelmaking production.

The specific difference between 75 ferrosilicon and 72 ferrosilicon

Ferrosilicon is an essential metallurgical product for steelmaking and casting. The main models are divided into 75# and 72#.

The role of ferroalloys in iron and steel smelting

Ferroalloy is an intermediate alloy composed of a kind of iron and one or several elements used in iron and steel smelting.

The difference and connection between ferrosilicon and manganese silicon

Both ferrosilicon and manganese silicon are added raw materials in steelmaking. They are mainly used to remove oxygen in steel and increase the toughness and strength of steel. They are indispensable substances in steelmaking.

The difference between metal silicon 441 and 553

Silicon metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Silicon metal is a product smelted from quartz and coke in an electric furnace. The main component silicon content is about 98%, and the remaining impurities are iron, aluminum, calcium, etc.

High-quality metallurgical additive, ferrosilicon-barium alloy

Silicon-barium alloy is an alloy product smelted by electric furnace, and its smelting materials are silica, coke, steel shavings, and barite.
