When we make a design of steel plant, firstly type of CCM  shall give full consideration combining the product process, product quality and project economic aspects. When the CCM works with electric furnace or converter, some points must be considered carefully. Points to be considered Multi-furnace continuous casting In order…

Continuous casting process will turn steel liquid into billets, in CCM unit main process equipment or machines as following. Ladle support equipment In continuous casting, ladles are generally used to supply steel to the continuous caster. The equipment that transports the ladle to the top of the intermediate tank and…

The Source of Nitrogen Nitrogen in steel is mainly inhaled and dissolved in the exposed process of steel.Electric furnace steelmaking, including secondary refining arc heating, accelerates the dissociation of gas, so the content of nitrogen is high. Long smelting time in open hearth furnace increases nitrogen content. Improper control of…

The Source of oxygen There is a certain amount of oxygen in molten steel during steel smelting. Oxygen is supplied in the production process, because oxidation and the removal of P, S, Si and C all requires the supply of oxygen to molten iron. However, there are various steelmaking processes,…

The Source of hydrogen The main ways for hydrogen to enter the liquid steel are: through the rust on the scrap steel surface (xFeO?yFe3O4?2H2O); Hydrogen in ferroalloy; Water in carburizer, deoxidizer, mulch, insulation, slagging agent (Ca(OH)2), bitumen and tar; Ladle, tundish and injection pipe undried; Spray coating of ingot mould;…

Ladle furnace is mostly used in the refining of bearing steel, alloy structural steel, tool steel, spring steel, carbon steel and other steel types. Electric arc furnace, LF and CCM combine into a high efficiency short process production line with remarkable refining effect. The LF can refine the liquid with…

For the electric furnace steelmaking, ingredients is related to whether the melting can smoothly operate andcost of the production. The reasonable ingredients can shorten melting time. Firstly it should carefully calculate correctly and accurate weighing the charge, next the size of the furnace charge should be fit  proportionally. Thirdly various ingredients…

In principle, investors of EAF-steelmaking project should check carefully whether there are enough prerequisite conditions, then make a thoughtful plan of the project. Following five crucial factors should be primarily reviewed: 1.Product positioning Product positioning mainly includes product kinds, specifications and product quantity. It is difficult for a steel plant…
