Carbon Electrode Paste Briquettes Sodeberg Electrode for Ferroalloy in Saf

Brief introduction:

High carbon silicon ball deoxidizer is a product of silicon iron powder end, recarburizer powder as raw material, vacuum high pressure extrusion and drying. Silicon carbon spheres can be used as an alternative to ferrosilicon and recarburizers, and do not cause dust pollution in the furnace. The reaction speed is fast, the recovery rate is high, and the cost is reduced. This is a new way in the process of casting iron.

BACKGROUND OF HIGH CARBON

The invention relates to briquettes which are useful as feed material, particularly in iron and steel making processes and, more particularly to a high carbon content briquette and process for preparing same.

The production of suitably stable agglomerates from fine or coarse particles of iron oxide for use as feed material in iron and steel making furnaces is a well-established and rapidly expanding field. It is a further object of the present invention to provide a high carbon content briquette which is useful as a feed material in iron and steel making furnaces, and which has excellent physical properties.

Other objects and advantages of the present invention will appear hereinbelow.Production of such agglomerates are accomplished by means of bonding particles using suitable cementing particles or binders, followed by sintering, firing and cementing procedures. Hot briquetting is a process whereby iron ore particles are agglomerated using compacting techniques and the proper combination of chemical reduction, heat and pressure. Briquettes produced using such techniques are commercially known as hot briquetted iron (HBI). The hot briquetting technique, without binders, has been successfully completed using highly metallized materials which contain from about 0.01% up to a maximum of 2% carbon. When the carbon content exceeds 2%, known compacting techniques do not provide a sufficiently stable agglomerate material.

Thus, the need exists for a process for preparing briquettes from starting material having a higher carbon content.

It is therefore the primary object of the present invention to provide a process whereby high-carbon content iron particles can be agglomerated so as to provide a suitable stable briquette.

Characteristics & advantage:

* High Carbon Silicon Briquette can effectively shorten the deoxidation time of steelmaking

Silicon ball contains rich silicon element, in the process of steelmaking silicon element can play an affinity with the oxygen in the steel, and effectively shorten the deoxidation time, improve the quality of steel.

* The High Carbon Silicon Briquette can improve the purity of liquid steel

In the process of steelmaking, are Silicon Briquette added to the slag collection and slag discharge, which can concentrate the oxide in the liquid steel and filter it out easily through the filter equipment, effectively improving the purity of liquid steel.

* The High Carbon Silicon Briquette has the function of reducing smelting cost

Silicon Briquette as a new type of metallurgical material with low price and good effect, compared with the traditional metallurgical material, can greatly reduce the cost of smelting, effectively improve the manufacturer's profit.

*High Carbon Silicon Briquette can effectively increase the yield of steelmaking

High Carbon Silicon Briquette has the function of alloying agent, can make the reaction in molten steel more thorough, effectively improve the elasticity and toughness of finished steel, so that the rate of steel production greatly increased.

* High Carbon Silicon Briquettel has the effect of raising furnace temperature

High Carbon Silicon Briquette are also a kind of heat-resistant material, which can effectively improve the furnace temperature, make the raw materials can be fully smelted in a high temperature environment, and effectively reduce the waste of energy.
