Ferro-tungsten production methods are agglomeration method, iron extraction method and aluminum heat method.

Calcium silicate cored wire (CaSi Cored Wire) is a type of cored wire used in steelmaking and casting applications. It is designed to introduce precise amounts of calcium and silicon into molten steel to aid in deoxidation, desulphurization and alloying. By promoting these critical reactions, cored wire improves the quality, cleanliness and mechanical properties of the steel.

Vanadium is an important alloying element mainly used in the steel industry. Vanadium-containing steel has excellent properties such as high strength, high toughness, and good wear resistance, so it is widely used in machinery, automobiles, shipbuilding, railways, aviation, bridges, electronic technology, defense industry and other industries

The production methods of low and medium carbon ferromanganese mainly include electrosilicon thermal method, rocker method and oxygen blowing method.

Black silicon carbide is made from quartz sand and petroleum coke silica as main raw materials through high-temperature smelting in a resistance furnace. Its hardness is between corundum and diamond, its mechanical strength is higher than corundum, and it is brittle and sharp. Green silicon carbide is made from petroleum coke and silica as the main raw materials, with salt added as an additive, and smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, and its mechanical strength is higher than corundum.

Ferromolybdenum is an alloy of molybdenum and iron and is mainly used as a molybdenum additive in steelmaking. Adding molybdenum to steel can make the steel have a uniform fine-grained structure, which can help remove temper brittleness and improve the hardenability of the steel. In high-speed steel, molybdenum can replace part of tungsten. Along with other alloying elements, molybdenum is widely used in the production of heat-resistant steels, stainless steels, acid-resistant steels and tool steels, as well as alloys with special physical properties. Adding molybdenum to cast iron can increase its strength and wear resistance. Ferromolybdenum is usually smelted by metal thermal method.
