CHAENG(Great Wall Machinery) strictly controls the quality of liner in processing and manufacturing to produce the best ball mill liner for customers.
First, the medium-frequency electric furnace is used for the smelting of high-quality scrap steel, manganese alloy, and other alloy materials, the treatment of microalloying, the hardening and tempering of quality, and casting with sand molding.
Second, the consent temperature pouring method is used to ensure the quality of products without sand, porosity, and collapse.
Finally, automatic temperature-controlled annealing technology changes the inner structure of the liner and to further improves mechanical performance. Advanced spectral detection is used to ensure chemical composition and stable performance in front of the furnace, after the furnace, semi-finished products, and finished products.
1. High manganese steel, with good physical and chemical properties, can withstand great impact for a long service life.
2. Constant temperature pouring to ensure the quality of products without sand, porosity and collapse.
3. Hardness, high toughness value and stable quality.
4. Custom-made service is available for all kinds of high-quality liner, bestselling at home and abroad, good service, and excellent quality.
