Abstract
The invention provides a low-carbon ferrochromium powder, which comprises the following components in percentage by weight: 60-80% of chromium powder, 0.03-0.045% of carbon powder, 0.85-1.28% of silicon powder, 0.015-0.032% of phosphorus powder, 0.015-0.028% of sulfur powder and the balance of iron powder. The low-carbon ferrochromium powder has the benefits as follows: the low-carbon ferrochromium powder is reliable and reasonable in component proportion and high in utilization ratio in the smelting process, generates few pollutants and impurities, has a better economic value and a better use value, and meets the requirements of sustainable development of environmental protection.
Description
Technical field
The present invention relates to a kind of chromic carbide iron powder.
Background technology
Chromic carbide iron is mainly for the production of stainless steel, acid resisting steel and heat resisting steel, and carbon content is fewer, and real economy is worth higher.At present, the smelting process of chromic carbide iron mainly contains electro silicothermic process and hot-metal process etc., the production link that these methods relate to is more, also relatively more serious to the pollution of environment, and the production cycle is long, efficiency is low, finished product impurity content does not much all reach requirement, cost is also relatively high, and due to the restriction of national industrial policies, a lot of relevant enterprise all cannot realize sustainable development.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of chromic carbide iron powder with good economic worth and use value.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Chromic carbide iron powder, in this chromic carbide iron powder, the percentage by weight of each composition is:
Chromium powder 60-80%;
Carbon dust 0.03-0.045%;
Silica flour 0.85-1.28%;
Phosphorus powder 0.015-0.032%;
Sulphur powder 0.015-0.028%;
All the other are iron powder.
The particle diameter of described chromium powder is 80-90 order.
The particle diameter of described carbon dust is 80-90 order.
The particle diameter of described silica flour is 120-130 order.
The particle diameter of described phosphorus powder is 280-300 order.
The particle diameter of described sulphur powder is 280-310 order.
The particle diameter of described iron powder is 230-250 order.
The invention has the beneficial effects as follows: chromic carbide iron powder of the present invention, its each composition proportion is reliably reasonable, and in smelting process, utilization rate is high, and the pollution produced and impurity less, there is good economic worth and use value, meet the requirement of Green Sustainable.
