Brief Introduction

Our comprehensive sponge iron tunnel kiln solutions are tailored to meet the diverse production needs of the metallurgical industry, integrating advanced thermal engineering, intelligent control, and environmental protection technologies. Designed for continuous and stable sponge iron sintering, these solutions optimize the entire production process from material feeding to finished product discharge. We prioritize customization, adjusting kiln parameters, structure, and supporting systems according to clients’ specific output requirements, raw material characteristics, and environmental standards. By combining high-efficiency thermal transfer design with energy-saving mechanisms, our solutions not only enhance production efficiency but also ensure consistent product quality, while minimizing environmental impact. Ideal for medium and large-scale sponge iron manufacturers, our solutions provide a reliable, cost-effective, and sustainable production pathway to elevate market competitiveness.

Features

Customized High-Efficiency Operation

We customize the tunnel kiln’s length, cross-sectional size, and heating system layout based on clients’ output goals and raw material properties. The optimized thermal circulation design ensures uniform temperature distribution, reducing heat loss by 15-20% compared to traditional kilns. Equipped with variable-frequency speed control for the conveying system, the solutions adjust production rhythm flexibly, realizing efficient continuous production and increasing unit output by up to 25% while lowering energy consumption per ton of product.

Stable and Superior Product Quality

The intelligent temperature and atmosphere control system enables real-time monitoring and precise regulation of sintering parameters, ensuring stable reduction reactions. This minimizes fluctuations in sponge iron quality, such as iron content, metallization rate, and particle size uniformity. The sealed kiln structure prevents air leakage, avoiding secondary oxidation of products, and effectively improving the purity and performance of sponge iron, meeting high-standard requirements for downstream steelmaking and casting applications.

Eco-Friendly and Sustainable Design

Our solutions integrate advanced flue gas treatment systems, including desulfurization, denitrification, and dust removal devices, which reduce harmful emissions (such as SOx, NOx, and particulate matter) to meet strict national and international environmental standards. We also adopt waste heat recovery technology to reuse waste heat for preheating raw materials or heating workshops, improving energy utilization efficiency. The use of high-temperature resistant and environmentally friendly refractory materials extends kiln service life and reduces solid waste generation, achieving green and sustainable production.

Application

Our sponge iron tunnel kiln solutions are widely applicable to the production of sponge iron (direct reduced iron) from various iron-bearing raw materials, such as iron ore pellets, lump ore, and mill scale. They are particularly suitable for medium and large-scale metallurgical enterprises engaged in steelmaking, casting, and ferroalloy production, which require high-quality sponge iron as a raw material. Additionally, these solutions are adaptable to different regional environmental regulations, making them ideal for applications in both developed and emerging markets. They can also be customized for special scenarios, such as the production of low-carbon sponge iron for green steelmaking and the processing of secondary iron-containing resources, supporting circular economy development in the metallurgical industry.
