Forging Carbon Steel Girth Gear
Casting & forging ability
CITICHL is the casting & forging center in central-south China, possessing 50t electrical arc furnace, 60t LF ladle refining furnace, and 60t VD/VOD refining furnace, and so on. We can pour 350t liquid metal a single time and yields more than 200,000t of high good quality liquid metal and can make the high good quality metal of far more than 260 steel grades these kinds of as carbon steel, structural alloy steel and the structural steel, refractory metal and stainless metal of specific requirement. The highest excess weight of casting, gray casting, graphite forged iron and non-ferrous casting is 200t, 30t, 20t and 205t independently.
The business is the forging centre in central-south China. It is extremely strong in forging. The one totally free forging is 100t(max bodyweight). We can roll rings of diverse sections of carbon steel, alloy steel, higher temperature alloy and non-ferrous alloys these kinds of as copper alloy, aluminum alloy and titanium alloy. The optimum diameter is 5.5m and solitary piece of the forging weighs 10t. We have 8400t, 3150t, 1600t, h2o press and Raw two hundred/a hundred and sixty-5000/750 huge-dimensions ring mill of substantial precision in Asia created in WAGNER, Germany.
Warmth remedy ability
The organization is the heat therapy 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, 8.5×13m,5×15m,6×14.5m,four.5×18m automated managed car variety warmth remedy furnace team. We can source the quenched and tempered element above 45t, the carburizedand quenched gear and pinion under 20t, shaft≤5.7m in duration and the induced girth ring diameter≤5m
