Casting & forging ability
CITICHL is the casting & forging center in central-south China, possessing 50t electric arc furnace, 60t LF ladle refining furnace, and 60t VD/VOD refining furnace, etc. We can pour 350t liquid steel one time and yields more than 200,000t of high quality liquid steel and can produce the high quality steel of more than 260 steel grades such as carbon steel, structural alloy steel and the structural steel, refractory steel and stainless steel of special requirement. The maximum weight of casting, gray casting, graphite cast iron and non-ferrous casting is 200t, 30t, 20t and 205t separately.The company is the forging center in central-south China. It is very powerful in forging. The single free forging is 100t(max weight). We can roll rings of different sections of carbon steel, alloy steel, high temperature alloy and non-ferrous alloys such as copper alloy, aluminum alloy and titanium alloy. The maximum diameter is 5.5m and single piece of the forging weighs 10t. We have 8400t, 3150t, 1600t, water press and RAW 200/160-5000/750 large-size ring mill of high precision in Asia made in WAGNER, Germany.Ourgirth gearsFeatures
