In the wave of high-quality development in the steel industry, slag-blocking balls, as a key consumable in converter steelmaking, directly determine the purity of molten steel and production efficiency. Our company, with 28 years of technological accumulation and innovation capabilities, has become a leading enterprise in the domestic refractory materials industry, and its homogeneous slag-blocking balls have become the preferred choice for many steel companies. This article will deeply analyze the strategic necessity of purchasing slag-blocking balls from our company from three dimensions: technology, cost, and environmental protection.

技术领先：技术技术铸就卓越品质
（一）核心技术技术突破
我公司于2012年成功研发的“一种均质挡渣球”技术（技术号：CN103627845A），解决了传统挡渣球易熔蚀、挡渣率低的行业痛点。该技术采用耐火材料细粉除铁粉作为主要原料，通过独特的配方设计，使挡渣球比重达到4.0-4.5g/cm³，介于钢水（7.0-7.2g/cm³）与炉渣（2.8-3.2g/cm³）之间，能够精准悬浮于钢渣界面，实现高效挡渣。
Technological Leadership: Patented Technology Creates Superior Quality
(I) Breakthrough in Core Patented Technology
In 2012, our company successfully developed a "homogeneous slag-blocking ball" technology (technology number: CN103627845A), which solved the industry pain points of traditional slag-blocking balls being easily eroded and having a low slag-blocking rate. This technology uses fine refractory powder and iron removal powder as the main raw material. Through a unique formula design, the specific gravity of the slag-blocking ball reaches 4.0-4.5 g/cm³, between that of molten steel (7.0-7.2 g/cm³) and slag (2.8-3.2 g/cm³), enabling it to precisely suspend at the steel-slag interface and achieve highly efficient slag blocking.

（二）间接成本节约
提高合金收得率：挡渣球能够有效减少炉渣进入钢包，降低合金元素氧化损失。数据显示，采用我公司挡渣球后，锰的收得率可从80%-85%提高到85%-90%，硅的收得率可从70%-80%提高到80%-90%，每年可为中型钢厂节省合金成本数百万元。
延长钢包使用寿命：转炉渣碱度高、氧化性强，对钢包耐火材料侵蚀严重。使用我公司挡渣球后，钢包渣层厚度降低，可减少炉渣对钢包内衬的冲刷和化学侵蚀，延长钢包使用寿命20%-40%，降低钢包维护成本。
减少脱氧剂消耗：挡渣效果提升后，钢包顶渣中FeO含量降低，减少了脱氧剂消耗。对于日产钢100炉的炼钢厂，若每炉少出200kg渣，每年可节省脱氧剂成本约440万元。

(II) Indirect Cost Savings
Increased Alloy Yield: Slag-blocking balls effectively reduce slag entering the ladle, lowering the oxidation loss of alloying elements. Data shows that after adopting Hongda Furnace Industry's slag-blocking balls, the manganese yield can increase from 80%-85% to 85%-90%, and the silicon yield can increase from 70%-80% to 80%-90%, saving medium-sized steel plants millions of yuan in alloy costs annually.
Extended Ladle Service Life: Converter slag has high basicity and strong oxidizing properties, severely corroding the ladle refractory materials. Using Hongda Furnace Industry's slag-blocking balls reduces the slag layer thickness in the ladle, reducing slag erosion and chemical corrosion of the ladle lining, extending the ladle service life by 20%-40%, and reducing ladle maintenance costs.
Reduced Deoxidizer Consumption: Improved slag-blocking effect reduces the FeO content in the ladle top slag, decreasing deoxidizer consumption. For a steel plant that produces 100 heats of steel per day, reducing the slag output by 200 kg per heat can save approximately 4.4 million yuan in deoxidizer costs annually.
