Smelting
Only producers of the highest quality ingots are chosen to supply ingots for JS billet casting.
3 billet casting lines are operating and each line includes a 20MT smelting furnace with a deep well and hot top rod casting machine. JS also owns 2 automatic gas homogeneity furnaces for special billets.
JS’s equipment and technology is capable of producing alloys from series 1000 to series 7000. The monthly capacity of billet production is approximately 5000MT.
A German spectrum analyzer is used to test and control the metal composition of all alloys.
The metal composition of alloys is strictly implemented in line with AAMA 2604 standard and China GB/T5237.1-2000 standard.
