Sichuan Qitong Superfine Technology Co., Ltd. was established in 2020 and is located in Mianyang, China's Science and Technology City, with a registered capital of 10 million yuan. It is a technology-based enterprise integrating superfine
Powder production, contract processing, product development, and sales, and has established a solid cooperative foundation with hundreds of enterprises.
Qitong Superfine possesses strong equipment, production, and R&D capabilities, and has built a high-quality management team and a scientific research elite team specializing in superfine powder material research. The experimental center is equipped with various specifications and models of experimental processing
equipment for crushing, grading, activation modification, and granulation, as well as advanced laser particle size analyzers, whiteness meters, moisture meters, and tap density meters.
The company, centering on the national strategic goals of "carbon peak and carbon neutrality," adheres to the business philosophy of "gathering resources, strengthening capabilities, and seeking breakthroughs," aiming to build the company into a leading enterprise of high-end materials in the "dual-carbon economy."
The main components of Qitong Superfine's ferrophosphorus powder include elements such as Fe, P, Si, S, Mn, and C. It is a dark gray irregular powder, characterized by being non-toxic, odorless, and tasteless. The ferrophosphorus powder product is a superfine material processed by grinding using high-pressure air flow as the crushing medium, and the product particle size and mesh can be customized according to customer requirements.
Metallurgical industry applications: used as deoxidizers and alloy additives in steelmaking to enhance the strength and corrosion resistance of steel.
Product advantages:
(1) It has good electrical and thermal conductivity, unique anti-rust, wear resistance, salt spray resistance, and strong adhesion. It can replace zinc powder with low cost and high efficiency. It can improve the properties of the coating and the welding characteristics of heavy-duty anti-corrosion zinc-rich coatings, reduce zinc mist generated during welding and cutting of zinc-rich coatings, increase the density of the paint film, improve the working environment, and enhance labor protection, making it highly welcomed by the paint industry and user units.
(2) Compared with other ferrophosphorus products, it has a wider range of applications and better performance, comparatively shortens the steelmaking process, further improves the performance of steel products, enhances the fluidity of molten iron, increases the tensile strength of steel, and overall improves the wear resistance and corrosion resistance of steel.
Chemical Composition:
-
Phosphorus (P) content: Typically between 20-25%, depending on the application.
-
Iron (Fe) content: Typically between 70-75%.
-
Impurity content: Impurities such as Silicon (Si), Manganese (Mn), and Sulfur (S) need to be controlled at low levels, usually requiring: Silicon (Si) ≤ 1.5%, Manganese (Mn) ≤ 0.5%, Sulfur (S) ≤ 0.05%, Carbon (C) ≤ 0.1%.
Particle Size Distribution:
-
Particle size requirement: Typically between 0.1mm to 3mm, depending on the application.
-
Particle size distribution: Should be uniform, avoiding excessively large or small particles that could affect performance.
Density Requirement:
Melting Point Requirement:
Moisture Content Requirement:
Appearance Requirement:
Other Requirements:
-
Flowability: Should be good to facilitate transportation and addition.
-
Storage Stability: Should remain stable during storage and transportation, resistant to oxidation or deterioration. These indicators ensure that ferrophosphorus powder performs optimally in metallurgical processes, with specific standards potentially varying by manufacturer and application.、
