Our company's magnesia-carbon bricks, with their superior performance and significant market advantages, will safeguard your choice. Our magnesia-carbon bricks possess the following characteristics:

一， 卓越性能， 品质优越

高温性能卓越，耐热震性优异

镁碳砖以高纯度的氧化镁颗粒和优质碳材料作为主要原料。氧化镁作为一种高熔点（2800℃）的碱性氧化物，为镁碳砖提供了坚实的耐高温基础。碳材料的加入，不仅赋予了镁碳砖良好的导热性能，还使其在高温环境下能够有效抵抗热冲击，降低热膨胀系数和弹性模量，减少因温度急剧变化而导致的崩裂和剥落现象。
我公司生产的镁碳砖常见有多种氧化镁含量规格，如72%氧化镁、74%氧化镁、76%氧化镁、80%氧化镁、82%氧化镁、85%氧化镁等，能够满足不同高温工业场景的多样化需求。这些镁碳砖在1400℃×30min的高温环境下，抗折强度依然能够保持在较高水平，如MT10A型号的镁碳砖，1400℃×30min的抗折强度≥6MPa，充分展现了其卓越的高温性能。

I. Superior Performance and Quality

Excellent High-Temperature Performance and Outstanding Thermal Shock Resistance

Magnesium-carbon bricks use high-purity magnesium oxide particles and high-quality carbon materials as their main raw materials. Magnesium oxide, as a high-melting-point (2800℃) alkaline oxide, provides a solid foundation for the high-temperature resistance of magnesium-carbon bricks. The addition of carbon materials not only endows magnesium-carbon bricks with good thermal conductivity but also enables them to effectively resist thermal shock in high-temperature environments, reducing the coefficient of thermal expansion and modulus of elasticity, and minimizing cracking and spalling caused by rapid temperature changes.

Our company produces magnesium-carbon bricks in various magnesium oxide content specifications, such as 72% magnesium oxide, 74% magnesium oxide, 76% magnesium oxide, 80% magnesium oxide, 82% magnesium oxide, and 85% magnesium oxide, to meet the diverse needs of different high-temperature industrial applications. These magnesia-carbon bricks maintain a high flexural strength even at 1400℃ for 30 minutes. For example, the MT10A model magnesia-carbon brick has a flexural strength of ≥6MPa at 1400℃ for 30 minutes, fully demonstrating its excellent high-temperature performance.

抗渣侵蚀能力强，耐冲刷性能好

镁碳砖对熔渣具有出色的抗侵蚀能力，这得益于其独特的材料组成和微观结构。碳材料的表面能低，熔渣难以在其表面润湿和渗透，能够有效阻挡熔渣对砖体内部的侵蚀。同时，氧化镁与熔渣中的成分发生反应，形成一层致密的保护层，进一步提高了镁碳砖的抗渣侵蚀性能。
在实际应用中，河南中工耐新材料公司的镁碳砖在转炉、电炉、钢包等高温设备的渣线部位表现出色。以转炉为例，渣线部位长期与高温熔渣接触，受到强烈的冲刷和侵蚀。使用该公司的镁碳砖后，能够有效减少熔渣对炉衬的侵蚀，延长转炉的使用寿命，降低维护成本。

Strong resistance to slag erosion and excellent scouring performance

Magnesium-carbon bricks exhibit outstanding resistance to molten slag erosion, thanks to their unique material composition and microstructure. The low surface energy of carbon materials makes it difficult for molten slag to wet and penetrate their surface, effectively preventing slag from eroding the brick's interior. Simultaneously, magnesium oxide reacts with components in the molten slag to form a dense protective layer, further enhancing the slag erosion resistance of the magnesia-carbon bricks.

In practical applications, magnesia-carbon bricks from SIR. have performed exceptionally well in the slag line areas of high-temperature equipment such as converters, electric furnaces, and ladles. Taking converters as an example, the slag line area is in long-term contact with high-temperature molten slag, subjecting it to intense scouring and erosion. Using the company's magnesia-carbon bricks effectively reduces slag erosion of the furnace lining, extends the converter's service life, and lowers maintenance costs.

热态抗蠕变性能佳，结构稳定性高
与其他陶瓷结合砖相比，河南中工耐新材料公司的镁碳砖具有良好的热态抗蠕变性能。在高温和外力作用下，砖体能够保持较好的结构稳定性，不易发生变形和蠕变。这一特性使得镁碳砖在长期高温服役过程中，能够始终保持良好的形状和尺寸精度，确保设备的正常运行。

Excellent hot creep resistance and high structural stability

Compared to other ceramic-bonded bricks, the magnesia-carbon bricks from Henan Zhonggong Naixin Materials Co., Ltd. exhibit excellent hot creep resistance. Under high temperatures and external forces, the bricks maintain good structural stability and are not prone to deformation or creep. This characteristic allows the magnesia-carbon bricks to maintain good shape and dimensional accuracy during long-term high-temperature service, ensuring the normal operation of equipment.

二、精湛工艺，铸就品质保障

1 优质原料，严格筛选
河南中工耐新材料公司对原材料的选择极为严格。生产镁碳砖主要使用电熔镁砂、石墨、金属铝粉、金属硅粉、液体酚醛树脂等原料。其中，电熔镁砂的MgO含量高达98%，保证了镁碳砖的高耐火度和抗渣侵蚀性能。石墨采用固定碳含量为94 - 95%、灰分含量为5%的天然鳞片石墨，为镁碳砖提供了良好的导热性能和抗热震性能。

II. Exquisite Craftsmanship, Guaranteed Quality

1. High-Quality Raw Materials, Rigorous Selection
Henan Zhonggong Naixin Materials Co., Ltd. maintains extremely strict selection criteria for raw materials. The main raw materials used in the production of magnesia-carbon bricks include fused magnesia, graphite, aluminum powder, silicon powder, and liquid phenolic resin. Among these, the fused magnesia has an MgO content as high as 98%, ensuring the high refractoriness and slag erosion resistance of the magnesia-carbon bricks. The graphite used is natural flake graphite with a fixed carbon content of 94-95% and an ash content of 5%, providing the magnesia-carbon bricks with excellent thermal conductivity and thermal shock resistance.

2 先进工艺，科学管控
在生产过程中，公司采用先进的生产工艺和科学的质量管控体系，确保每一块镁碳砖都符合高品质标准。首先，将各种原料按照预定比例进行精确配料，然后在强混砂机中进行充分混合，混合时间严格控制在15 - 45min，确保原料均匀分散。混合后的物料在成型机上进行压制成型，通过调整成型压力和时间，保证砖体的致密度和强度。最后，经过高温烘烤等后续处理工艺，进一步提高砖体的性能和稳定性。
此外，公司还拥有完善的质量检测设备和专业的检测团队，对每一批产品的化学成分、物理性能等进行严格检测，确保产品质量稳定可靠。

2. Advanced Technology and Scientific Management

During production, the company employs advanced production processes and a scientific quality control system to ensure that every magnesia-carbon brick meets high-quality standards. First, various raw materials are precisely proportioned according to a predetermined ratio, and then thoroughly mixed in a high-pressure sand mixer. The mixing time is strictly controlled between 15 and 45 minutes to ensure uniform dispersion of the raw materials. The mixed material is then pressed into shape on a molding machine. By adjusting the molding pressure and time, the density and strength of the bricks are guaranteed. Finally, subsequent processing, such as high-temperature baking, further improves the performance and stability of the bricks.

In addition, the company possesses complete quality testing equipment and a professional testing team to rigorously test the chemical composition and physical properties of each batch of products, ensuring stable and reliable product quality.
