Welcome to Tianjin Zhongying Chemical Co., Ltd., a premier source factory specializing in high-performance industrial chemical manufacturing and global export. Operating our modern manufacturing base in Inner Mongolia, and a strategic trade logistics hub in Tianjin, China, we maintain a stable monthly production capacity of over 6,000 metric tons. We are dedicated to providing global industrial buyers, chemical distributors, and metal fabrication plants with top-tier solid calcium carbide solutions engineered for maximum efficiency, stability, and high gas yield.
By leveraging rich regional mineral resources, state-of-the-art electric arc furnace technology, and strict international quality management standards, Tianjin Zhongying Chemical Co., Ltd. has established itself as a trusted long-term supply chain partner across Europe, the Americas, Southeast Asia, the Middle East, and Africa.
Among our wide array of granular options, our large-lump calcium carbide 50 80mm stands out as the industry-standard specification for heavy-duty industrial processing. This primary size is meticulously crushed, screened, and packed to ensure consistent structural integrity and optimal surface-area-to-volume balance during gas generation.
Utilizing large-format calcium carbide 50 80mm lumps allows commercial acetylene plants, steel mills, and welding operators to maintain steady, highly controllable chemical reaction rates while significantly minimizing fine dust loss and material wastage.
In addition to our flagship 50-80mm lump size, we offer a comprehensive spectrum of particle sizes engineered for distinct industrial reactors and feeding systems:
25–50 mm: Preferred for medium-scale acetylene generators requiring balanced gas evolution.
50–80 mm: The global benchmark size for large-scale industrial generators, steelmaking, and heavy chemical synthesis.
80–200 mm: Extra-large lumps designed for specialized high-capacity gas production plants.
Custom Sizing & Screening: On-demand custom mesh sizes available upon request for specific automated chemical feeders.
Our industrial-grade solid calcium carbide serves as a critical raw material across core global heavy industries:
Acetylene Gas Generation: Guarantees a stable gas yield of up to 295 L/kg to 305 L/kg, making it ideal for large-scale oxy-acetylene torch cutting, metal welding, and industrial gas refilling operations. High gas purity ensures clean combustion with minimal residue.
Steelmaking & Metallurgy: Functions as a high-potency desulfurizing agent and deoxidizer, assisting steel foundries and blast furnace operations in refining molten metal purity, reducing sulfur content, and achieving superior steel grade consistency.
Chemical Synthesis: Serves as a vital chemical building block for manufacturing Polyvinyl Chloride (PVC), calcium cyanamide (lime nitrogen synthetic fertilizer), vinyl monomers, synthetic rubber, and various organic chemical compounds.
Fruit Ripening & Agricultural Processing: High-purity acetylene liberated under controlled moisture conditions is widely utilized as an effective ripening agent for agricultural produce management in commercial orchards and processing hubs.
To ensure uninterrupted operational safety for our global clients, every production batch undergoes stringent testing in our in-house laboratories before dispatch.

We understand that evaluating total calcium carbide 50 80mm cost is a top priority for B2B procurement teams facing volatile global market conditions. By managing every stage of production—from raw lime thermal processing and high-grade carbon material selection to in-house steel drum fabrication—we eliminate unnecessary middleman markups.
This complete vertical integration enables us to deliver transparent bulk wholesale rates, long-term price protection contracts, and customizable payment terms (FOB, CFR, CIF) while ensuring uncompromised material quality and strict ISO9001/SGS safety compliance.
Safety is paramount when handling hazardous chemicals like solid calcium carbide 50 80mm (Class 4.3 dangerous goods, substances which in contact with water emit flammable gases). To prevent moisture contamination and oxidation during long-distance maritime transport:
Hermetic Nitrogen Flushing: All products are packed and hermetically sealed inside newly produced, heavy-duty 50kg or 100kg steel drums flushed with inert nitrogen gas.
Durable Drum Construction: Made with reinforced steel sheet thickness to withstand high stacking, vibration, and extreme atmospheric shifts during oceanic shipping.
Customization Services: Customers can fully customize drum colors, specialized inner foil/plastic linings, and international UN-approved shipping marks to meet regional regulatory and warehouse handling requirements.
Our strategic export office in Tianjin provides direct access to one of Northern China's largest sea ports, enabling efficient customs clearance, short lead times, and seamless container loading.
Whether you are looking to secure a stable monthly supply contract for large-scale chemical manufacturing or seeking competitive factory-direct quotes to lower your operational calcium carbide 50 80mm cost, Tianjin Zhongying Chemical Co., Ltd. is equipped to support your procurement needs.
