Mill cover is an important part of the grinding mill. Mill cover is supporting and connecting the mill shell which includes a feed mill cover and a discharge mill cover.
Mill Cover Process Measures:
Molten steel secondary refining(R-H vacuum treatment)
Modeling using special sand, strictly controlling the pouring temperature and casting speed
We supply following ball mill cover tests:
Rough casting mechanical properties and chemical composition
(internal standard)
Ultrasonic testing after rough machining
Ultrasonic testing and magnetic particle testing after finishing
Ball mill end cover:Â

Elongation
≥22MPA
We have experienced QCP successfully executed for quality controlling for many years. We have the honor that we are ability to guarantee the foundry quality against so large steel casting. It's very important for us to decrease the cost and short the delivery in subsequent processing. The material of mill head is normally selected low carbon steel and low alloy steel. Distinctively we're good at refining on all key knots, including chemical elements controlling in foundry and subsequent heat treated. Thus we have the ability to keep the material grasping the maximum potential perfermance.The products even if in frequently working condition or very cold circumstance can possess prolong service life

About our company casting & forging ability:Â
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.Â
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.
We have Various kinds of graphite rods are available, such as :
