LMM Carbon


LMM GROUP Production factory professionally engage in research and development, manufacturing and supplying, and international trade of graphite electrode and carbon products, we are the fist UHP manufacturer in china. By continuous development and innovation, now developed the complete process for the carbon production, including calcination, forming, baking, pitch impregnation, graphitizing, machining, as well as the advanced test equipment from China and abroad. The main products series: 250mm-700mm HP/RP Grade and UHP Grade graphite electrode. The annual capacity is 50 thousands MT. The company has passed ISO 9001: 2015 quality management system certification, product quality is stable and reliable.

Application of Grahite electrode

Graphite electrodes are currently the only products with high conductivity and the ability to withstand the extremely high heat generated in this harsh environment

LMM GROUP graphite electrodes have the characteristics of low resistivity, good conductivity, low ash content, dense structure, good oxidation resistance, and high mechanical strength. They are widely used in LF, EAF, nonferrous industries, and silicon phosphorus industries in the steelmaking industry. The best conductive material for electric arc furnaces and smelting furnaces.

LMM GROUP’s RP/HP/UHP graphite electrodes are made of high-quality materials to ensure maximum efficiency and performance. is your best choice

Advanced production equipment, professional production technology

LMM GROUP also equipped with world advanced facilities such as Laeis automatic hydraulic press HPF2500, Eirich R19 mixer, Shimadzu made XRF-1800 sequential X-Ray fluores-cence spectrometer, by focusing on product research and development and quality control. Our products also supply to Asia , Europe, America and Africa and other countries and regions.

2pre-assembling iron platforms one is 20m×20m, the other is 16m×16m. (level precise reaches +0.2mm )

    • Performance Testing

    We have a complete inspection system for testing and analyzing physical and chemical data of carbon material.

Packaging and Delivery of Graphite Electrodes

LMM GROUP has a prudent schedule and delivery system that enables us to manage large volumes of orders smoothly and on time. Since we have excellent connections with all major shipping lines, we are able to offer our customers the fastest connections and transit times to any destination around the world.

  • Nominal package type
    Electrodes are placed upon wooden pallet and braced strongly with high quality steel tape to be suitable for land and sea transportation. Nipples are packed in crates.
  • Pre-set package type
    Assembled electrodes and nipples are packed in crates. Nipples and sockets are protected with polyester caps. Keep the protective caps at each end in place and undamaged, this can protect the threads from damage by bumping and other abrasions.
