LMM Ironmaking














LMM-Better raw materials to ensure better quality!

Traditional same type products generally use the inferior fused brown corundum as aggregate, which alumina is above 94.5% with higher porosity, and more wear-resistant. LMM uses high-quality tabular corundum as aggregate: the Al₂O₃ content is more than 99% with smaller pores and more closed pores, higher purity, and better volume stability.

1.Iron erosion advantage. Compared with 9% iron erosion area of traditional brown corundum furnace cylinder pouring material, the iron erosion area percentage of LMM is 8%.
2. Slag erosion advantage. The erosion area percentage of the traditional brown corundum casting slag is 7%, while the erosion area percentage of LMM is only 2%.
3. Strength performance advantages.

When the temperature is 110℃, the pressure resistance of other castable is 27MPa, while LMM castable is 55MPa. At 815℃, LMM castable play a more significant advantage, rolling property is higher 31.8MPa than others! At 1450℃, LMM’s castable is also 10MPa higher than others.


LMM Group mainly provides a series of unshaped refractory products such as various spray (coating) materials and pouring materials for the steel industry.
We have established stable technical cooperation relationships with universities and R&D institutions such as Beijing University of Science and Technology, Northeastern University, and Wuhan University of Science and Technology, which will ensure that our technological innovation and application are always at the forefront of the industry.
Our products are environmentally friendly, long-lasting and efficient. It has been successfully used in blast furnace injection (coating), hearth pouring, cooling stave pre-casting, hot blast stove repair, sintering injection (coating), gas system spraying and other fields in hundreds of steel companies, ranking Hebei Blast Furnace at the forefront of the industry Spray coating market. It also enjoys a good reputation in the industry for its “high efficiency, good quality, comprehensive service and excellent integrity”.

LMM has a unique, strict, complete and mature quality control system.The whole quality control process combines raw material inspection of raw material procurement, prenatal inspection of production process, first-plate inspection, product process inspection and product performance inspection, and then inspection of construction sample blocks used. The company’s products from procurement, to production, and then to specific use, carry out heavy checks in the whole process, and meet the various standards of each raw material and each product can be qualified for delivery. Once the unqualified items are found, they will be dealt with immediately to ensure the 100% pass rate of the factory products and ensure the product quality as far as possible.
LMM has a traceability system for the whole process of quality control. The quality control system of LMM includes a perfect test record system, which can achieve the quality traceability of the whole process to ensure that problems found at any process node can be traced back in time to further ensure product quality;

LMM has a professional testing laboratory. We have relatively complete equipment and instruments that can measure various indicators of raw materials such as: volume density, water absorption, apparent porosity, packaging density, specific gravity, viscosity, particle size distribution, chemical composition, pH, moisture content, fluidity, initial setting and final setting. The setting time, etc. are accurately tested in compliance with national standards. Various indicators of the product can be measured, such as: fluidity, working time, setting time, volume density at each firing temperature, normal temperature flexural strength, normal temperature compressive strength, and permanent linear change. The efficiency, wear resistance, slag corrosion resistance, chemical composition, etc. are accurately tested in compliance with national standards, and all equipment and instruments are regularly maintained and calibrated as required to ensure the accuracy of various quality test results and further ensure product quality. 

LMM has a professional and reliable quality inspection team. The testing personnel have received special training within the company and are responsible for each testing indicator and data to ensure the authenticity and accuracy of the data, ensure that the measurement error is within a reasonable range, and further ensure product quality.
