tundish covering agent exporters, tundish covering agent manufacturer, tundish covering agent supplier, tundish covering agent suppliers Overview

Tundish covering agents are engineered insulating and/or exothermic granules applied to the molten steel surface in the tundish to minimize heat loss, reduce reoxidation and nitrogen pick-up, suppress slag entrapment, and stabilize flow during continuous casting. In Iron and Steel Metallurgy, the tundish is critical for inclusion control and steady casting; a high-quality covering agent safeguards superheat and casting stability, directly impacting slab/billet quality and yield.

Technically, modern tundish covers feature controlled particle size distributions for rapid spread, low dusting during addition, and strong thermal performance at 1550–1650°C. Typical options include insulating grades (expanded mineral/ceramic matrices) and exothermic blends for superheat retention at start or end of sequence. Many steel plants target low Fe2O3, low alkali, and low sulfur/low phosphorus content to avoid secondary reactions, alongside moisture control below ~1% for safe use.

Xingtai Luxi Environmental Protection Technology Co., Ltd., a dependable tundish covering agent manufacturer and global supplier, offers eco-friendly particle formulations designed for various caster types. With consistent bulk density and tight granulation, our products support long sequence casting, reliable nozzle performance, and clean steel targets across billet, bloom, and slab operations.

Benefits & Use Cases of tundish covering agent exporters, tundish covering agent manufacturer, tundish covering agent supplier, tundish covering agent suppliers in Continuous casting auxiliary materials

In continuous casting, tundish covering agents are applied immediately after tundish fill and maintained throughout the sequence. Use cases span BOF and EAF routes, across billet/bloom casters requiring robust insulation and slab casters prioritizing surface quality and sequence stability. Insulating grades help retain 20–30°C of tundish temperature compared with uncovered conditions, while exothermic grades assist in start-ups or low superheat events. The right layer thickness typically ranges from 20–40 mm depending on steel grade, sequence length, and tundish geometry.

Key advantages include:
- High thermal insulation, limiting superheat loss and reducing reheating risk
- Fast, even spread with minimal dust for safer, cleaner operation
- Low reactivity and low impurity profile to protect steel cleanliness
- Easy raking and minimal residue, supporting fast turnaround

As active tundish covering agent exporters and a trusted tundish covering agent supplier, Xingtai Luxi delivers formulations tailored to caster design, tundish practice, and climate (moisture sensitivity). The company’s process control ensures batch-to-batch consistency, while packaging options (25 kg bags or FIBCs) streamline handling. Our technical team supports trials and optimization, helping users standardize addition rates and layer management for stable sequences and improved yield.

Cost, Maintenance & User Experience

Total cost of ownership for covering agents encompasses unit price, consumption (kg per ton of steel or per m² of tundish surface), and the downstream savings derived from temperature retention, reduced nozzle issues, and lower skull formation. Plants frequently observe lower energy input and fewer flow disruptions when the cover is properly specified and maintained, translating to fewer interruptions and higher caster productivity. Over time, improved tundish hygiene can reduce refractory wear and cleaning time between sequences.

From user experience, decision makers value predictable spreadability, low dust, and minimal moisture sensitivity. Customers in Asia and the Middle East have reported improved tundish temperature stability and reduced addition frequency after switching to Xingtai Luxi’s eco-friendly particle covering agent, contributing to measurable ROI within months of adoption. While results vary by practice, consistency in particle sizing and bulk density is often cited as a driver of reliable performance and lower overall consumption.

Maintenance is straightforward: store bags in a dry, ventilated area; avoid contact with water; and control addition thickness based on steel grade and sequence length. Our tundish covering agent suppliers provide application guidelines, on-site support, and post-trial reviews so mills can fine-tune dosing and realize cost benefits without compromising steel cleanliness.

Sustainability & Market Trends in Metallurgical Industry

Decarbonization and clean steel initiatives are reshaping auxiliary material selection. The market favors low-dust, fluorine-free options and packaging that reduces waste and improves safety. Environmental regulations increasingly scrutinize emissions, workplace exposure, and disposal, prompting mills to standardize on cleaner, more efficient covering agents that maintain steel quality with less material.

Xingtai Luxi Environmental Protection Technology Co., Ltd. aligns with these trends through eco-friendly particle solutions, energy-conscious manufacturing, and responsible sourcing. As a forward-looking tundish covering agent manufacturer and exporter, we prioritize stable quality, safe handling, and documentation support (such as MSDS and COA) to meet regional requirements. With supply chain resilience and technical service, we help B2B decision makers de-risk operations, harmonize practices across sites, and adopt greener, performance-driven products without sacrificing throughput or quality targets.
