HC silicon

HC silicon Introduction:

HC silicon is a new type of alloy used in converters, and can also be called silicon-carbon alloy. It can replace ferrosilicon, silicon carbide, recarburizer, reduce the amount of deoxidizer, used in converter smelting deoxidation alloying process, the effect is stable, steel chemical composition, mechanical properties and internal control quality are better than traditional processes.

Common grades of high carbon silicon: 6515/6818;

Features of HC silicon:
Improve the quality of molten steel, improve product quality, improve product new capabilities, reduce the amount of alloy added, reduce steelmaking costs, and increase economic benefits.

The experiment and production application show that the deoxidizing alloy process using HC silicon has greatly reduced the cost per ton of steel, created considerable economic benefits and improved the market competitive advantage of steel.

Advantages of HC silicon:

  1. The advantages of HC silicon deoxidation

Silicon-carbon alloy contains silicon element. After the silicon-carbon alloy is added in the steelmaking process, the silicon element in it interacts with oxygen to deoxidize the oxygen in the molten steel to increase the hardness and quality of the steel. The silicon element in the silicon-carbon alloy and the Oxygen has a good affinity, so molten steel still has the characteristic of not splashing after being put into it.

  1. The advantages of HC silicon slag collection

High-carbon silicon also has the advantage of slag collection. Putting a certain proportion of silicon-carbon alloy into the molten steel can allow the oxides in the steelmaking process to quickly clump together, which is convenient for filtration treatment, makes the molten steel more pure, and greatly improves the density and hardness of the steel. .

  1. The advantages of HC silicon to increase furnace temperature

High-carbon silicon is a good temperature-resistant material. Putting silicon-carbon alloy in the process of steelmaking can increase the furnace temperature, increase the conversion rate of ferroalloy, and accelerate the reaction speed of molten steel and elements.

  1. HC silicon allows many manufacturers to save costs

Today, ferroalloy materials are more expensive. As a new type of metallurgical material, silicon-carbon alloy is favored by many manufacturers because of its lower price than traditional metallurgical materials. High-carbon silicon can replace expensive metallurgical materials such as ferrosilicon and achieve unexpected results. Satisfactory results, so the use of silicon-carbon alloy can save manufacturers’ costs and increase profits;
