Silicon Chromium Alloy Blocky For Refractory And Cast Iron

Silicon Chromium Description

Silicon chromium is an iron alloy mainly composed of silicon, chromium and iron. Also known as ferrosilicon chromium alloy. It is mainly used as a master alloy for the production of medium, low and micro carbon iron by electro-silicothermal process. Used as a deoxidizer (in place of ferrosilicon) and as a chromium additive in steelmaking. Typically, it contains Cr>30% and Si>35% with excess iron and small amounts of impurities. Classified according to carbon content, such as carbon ≤ 0.06%, ≤ 0.10%, ≤ 1.0%, etc.

Alloys containing not less than 30.0% chromium and not less than 35.0% silicon. The process can be divided into two types: a one-step process (often called "slagging" or "ore") and a two-step process (often called "slagging"). The raw materials for one-step smelting are silica, chrome ore and coke. The raw materials for the two-step smelting are silica, carbon ferrochromium and steel scraps. Both smelting methods use coke as a reducing agent.

Silicon Chromium Application

1. Metallurgical industry

Chromium is hard, often mixed into steel to make hard, corrosion-resistant alloys, mainly used for refining stainless steel, heat-resistant steel and various electric heating materials.

2. Chemical industry

Various chromium salts produced by processing chromite are the main raw materials in the chemical industry. Chromium salts are one of the main varieties of inorganic salts. It is widely used in daily life. Mainly used in electroplating, tanning, printing and dyeing, medicine, fuel, catalyst, oxidant, matches and metal corrosion inhibitor.

3. Refractory and cast iron

Since chromite has a melting point of up to 1900 °c 2050 °c, it retains its volume at high temperatures and does not react with any slag. Therefore, it can be used as a refractory material, as a lining for steelmaking furnaces and non-ferrous metal smelting furnaces.

4. In addition, chromium is also used in cast iron. For example, chrome cast ductile iron
