Casting & forging capacity
CITICHL is the casting & forging heart in central-south China, possessing 50t electric arc furnace, 60t LF ladle refining furnace, and 60t VD/VOD refining furnace, and many others. We can pour 350t liquid metal a single time and yields much more than two hundred,000t of  higher high quality liquid steel and can generate the high high quality metal of far more than 260 steel grades this sort of as carbon metal, structural alloy metal and the structural metal, refractory steel and stainless steel of special prerequisite. The highest fat of casting, grey casting, graphite forged iron and non-ferrous casting is 200t, 30t, 20t and 205t independently. 
 
The company is the forging center in central-south China. It is quite effective in forging. The single cost-free forging is 100t(max fat). We can roll rings of distinct sections of carbon steel, alloy metal, large temperature alloy and non-ferrous alloys these kinds of as copper alloy, aluminum alloy and titanium alloy. The greatest diameter is five.5m and one piece of the forging weighs 10t. We have 8400t, 3150t, 1600t, water push and Raw 200/one hundred sixty-5000/750 large-size ring mill of high precision in Asia made in WAGNER, Germany.

 

Warmth treatment capability
The organization is the warmth therapy base in national equipment 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,4.5×18m computerized managed vehicle kind heat remedy furnace team. We can supply the quenched and tempered part over 45t, the carburizedand quenched gear and pinion below 20t, shaft≤5.7m in duration and the induced girth ring diameter≤5m
