Product Introduction

High Carbon Low Sulfur 0.05% Graphite Petroleum Coke Carburizer is a premium graphitized carbon additive tailored for the global steelmaking, iron casting and metallurgy industries. Manufactured through high-temperature graphitization treatment, this carburizer features high fixed carbon content, extremely low sulfur at 0.05% maximum, minimal ash and volatile matter. Compared with conventional carburizing materials, it delivers higher carbon absorption rate, faster dissolution speed and more stable metallurgical performance during molten metal processing.

Strict raw material screening and standardized production processes ensure consistent quality across every batch. It effectively solves common industrial pain points such as unstable carbon content, excessive impurities and high defective rates, making it a reliable carbon raising solution for high-end casting and steel production.

Product Qualification

Core Features

Controlled 0.05% Max Sulfur: The ultra-low sulfur index avoids sulfur-induced defects like porosity and cracks in steel and castings, fully compliant with strict quality standards for high-grade metal materials.
Superior High Carbon Purity: High fixed carbon proportion greatly improves carbon utilization, reduces raw material waste and lowers overall production costs for foundries and steel plants.
Excellent Graphitization Structure: Uniform graphite particle structure enables rapid and even carbon dissolution in molten steel and iron, realizing precise carbon adjustment and stable product quality.
Low Ash & Low Volatile Content: Less impurities and smoke during smelting create a cleaner production environment while improving the toughness and finish of finished metal products.
Stable Batch Consistency: Mature high-temperature graphitization technology ensures no drastic fluctuation in core indicators, supporting long-term and stable bulk procurement for global industrial clients.

Industrial Applications

This High Carbon Low Sulfur 0.05% Graphite Petroleum Coke Carburizer is widely applicable to electric furnace steelmaking, converter steelmaking, gray iron casting, ductile iron casting, and various alloy smelting processes. It is particularly suitable for sophisticated manufacturing scenarios that require ultra-low sulfur indicators and high-precision carbon control.

Product Advantages

Most ordinary petroleum coke carburizers on the market suffer from unstable sulfur content, low carbon absorption and severe quality fluctuation, which easily lead to unqualified metal products and increased production loss. Our 0.05% low sulfur graphite petroleum coke carburizer adopts strict ingredient control and full graphitization processing. It significantly enhances carbon recovery efficiency, stabilizes molten metal composition, and effectively reduces product defective rates. For industrial manufacturers, it is a cost-effective and high-stability carburizing agent that optimizes overall production benefits.

FAQ

Q: What does 0.05% sulfur mean for casting and steelmaking quality?

A: 0.05% max sulfur is an ultra-low sulfur grade that greatly reduces sulfur-related defects such as cracks, porosity and brittleness in finished steel and cast iron. It is essential for producing high-grade steel, ductile iron and precision castings where strict sulfur control is required. Using this low-sulfur carburizer helps factories meet higher industry quality standards and lower defective rates.

Q: What is the difference between graphite petroleum coke carburizer and ordinary carburizer?

A: Graphite petroleum coke carburizer is processed under high-temperature graphitization, which gives it a stable graphite crystal structure. It features higher carbon absorption, faster melting speed and much lower volatile content than regular carburizers. Ordinary carburizers often result in unstable carbon levels and more impurities, while GPC carburizer ensures precise carbon adjustment and consistent casting quality batch by batch.

Q: What particle sizes do you supply for this carburizer?

A: We provide customizable particle sizes to fit different furnace types and production processes, including 1-3mm, 3-5mm and custom powder sizes. Uniform particle size ensures stable feeding, even carbon dissolution and less smoke during smelting. Custom packaging and size specifications are available for bulk orders to match clients' specific production requirements.
