Ring Gear and Large Girth Equipment
Casting & forging ability
CITICHL is the casting & forging centre in central-south China, possessing 50t electric powered arc furnace, 60t LF ladle refining furnace, and 60t VD/VOD refining furnace, and many others. We can pour 350t liquid metal one time and yields far more than two hundred,000t of high good quality liquid steel and can generate the large quality steel of much more than 260 steel grades this kind of as carbon metal, structural alloy steel and the structural steel, refractory steel and stainless metal of specific requirement. The highest fat of casting, grey casting, graphite solid iron and non-ferrous casting is 200t, 30t, 20t and 205t individually.
The organization is the forging centre in central-south China. It is quite effective in forging. The single free forging is 100t(max fat). We can roll rings of different sections of carbon metal, alloy steel, large temperature alloy and non-ferrous alloys this kind of as copper alloy, aluminum alloy and titanium alloy. The maximum diameter is 5.5m and solitary piece of the forging weighs 10t. We have 8400t, 3150t, 1600t, water push and Raw 200/one hundred sixty-5000/750 massive-measurement ring mill of high precision in Asia produced in WAGNER, Germany.
Warmth remedy potential
The organization is the warmth remedy foundation in national machinery trade in central and south China, possessing Φ3×1.6m carburizing furnace, Φ2.3×17m,Φ2.3×9.5m shaft furnace, eight.5×13m,5×15m,6×14.5m,4.5×18m computerized managed automobile type heat therapy furnace group. We can offer the quenched and tempered portion over 45t, the carburizedand quenched equipment and pinion below 20t, shaft≤5.7m in length and the induced girth ring diameter≤5m
