A twin-stand Steckel Mill combines Steckel technology and tandem rolling. This mill type gives you the capacity to produce high-quality hot strip on a Steckel mill at production rates of 1 - 1.2 million t per year (without roughing stand) or up to 1.8 …
Roughing mill rolling of reheated slab: The roughing mill usually consists of one or two roughing stands in which the slab is hot rolled back and forth 5 or 7 times repeatedly to reach the minimum thickness requirement. The roughing mill also contains edger rolls that are used to roll the edge of slab and center it.
The steel roughing rolling mill stands are used to reduce the thickness of the steel while at the same time extending the overall length. Steel Roughing rolling mill stand is an important part of a work stand, roll bearing chock and roller …
Rebar rolling mill production line is for producing TMT rebar, and the main process is: after steel scrap smelting, cast into billets by continuous casting machine, the conveying roller passes the steel billet back and forth into the roughing unit …
At present, most of the newly-built and in-use rolling mills in the world are mostly continuous rolling mills. Rebar production process: (scrap steel melting furnace,Continuous casting machine,billet heating furnace)step heating furnace→roughing mill→medium mill→finishing mill→water cooling device→cooling bed→cold shear→automatic ...
If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours. At 114.16 tons/hour that …
Roughing, intermediate, finishing and breakdown mill upgrade at Evraz. The electrical and automation upgrade of the Evraz rod and bar mill was carried out in three phases in order to cause the least disruption to production. Phase 1– Roughing, Intermediate, Finishing & Breakdown Mill. Phase 2 – Rod Outlet Mill. Phase 3 – Finishing Block.
The two roughing mill stands assure high production flexibility and, in combination with the edger attached to the second roughing stand, tightest width tolerances. The seven-stand finishing mill, designed for maximum roll forces of …

G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 11.5.1 Hot rolling. Mill data from the hot strip mill has been used to calculate the mean flow stress in each pass, assuming the material to be elastic – ideally plastic. The roll force model used was a classical slab method with constant friction assumed in the roll gap. For the roughing mill (reversible 4-high) both roll force ...
Xi'an WeiKeduo Electrical and Mechanical Equipment Co., Ltd. with over 20 years experience in metallurgical industry, commits to high quality rolling process design and hot angle steel hot rolling mill manufacturing for wire rod, bar,rebar, tmt bar and other special steel production line, especially good at high-speed line design, as well,comprehensive installation …
Planetary mills; Screw rolling mills (radial-displacement rolling) Small-size two-high cogging mill trains; Sheet mill is a unit consisting of parts and mechanisms that ensure the production of sheet steel via rolling. Sheet mill products can be cut into sheets (2 to 50 mm thickness) or in the form of a rolled strip (3-20 mm thickness).
Roughing Shell Mills; Showing 1-11 of 11. SORT BY: PAGE SIZE: M42 Cobalt Roughing Shell End Mill. Item #: 10-304-128. Brand: TTC PRODUCTION Finish Coating: Bright Finish Cutting Direction: Right Hand Size: 2" Tool Material: M42 8% Cobalt Series: D43R Compare ...
The coil box is located between the roughing mill and finishing mill to coil the transfer bars after roughing passes. The coil box enables a shorter distance between the roughing mill and the finishing mill in a new plant as well as minimizes the temperature drop of the transfer bar entering the finishing mill.
Many manufacturers continue to rely on outdated machine end mill speed and feed parameters or insist on running their end mills at top speeds. In doing so, however, they forego the advantages of a relatively new milling strategy – optimized roughing – that offers significant benefits, including extended end mill life, better workpiece surface finishes and reduced need …

Figure 1 shows a fragment of the 2000 mill production line of the Magnitogorsk Metallurgical Combine (MMK): a continuous roughing train consisting of three (Nos. 4–6) universal stands coupled by the strip being rolled .
roughing mill, intermediate mill and finishing mill. To maintain stable tension conditions, the looper control is usually used and many looper control technologies have been recently developed for intermediate and finishing mills. However, loopers cannot be applied to roughing mill due to the big workpiece cross sectional area. Hence,
1. Purpose. Roughing is mainly to remove a large amount of excess material from the piece, finishing is to improve surface finish, tolerance, and reduce or minimize the errors. 2. Parameter. Higher feed rate and cut depth are applied in roughing. 3. MMR. The material removal rate in roughing process is higher than finishing. 4. Surface finish.
mance solution for drilling, roughing, and finishing on milling and mill-turn machines, namely its hyperMILL® MAXX Machining performance package. Milling tools tilted in the cutting direction can drill holes in materials that are difficult to machine both quickly and easily, and without any predrilling. Optimized pocket strategies
Roughing Mill. When the Going Gets Rough, NDC Gauging Systems Deliver. The roughing mill significantly reduces the thickness of steel while simultaneously extending the overall length of the product. Accurate length and speed measurements at the roughing mill require a well-engineered, reliable system due to the harsh environment that these ...

Coarse-Pitch Roughing (CPR) CPR series milling cutters are coarse-pitch HSSCo8 (High-Speed Steel with 8% cobalt) roughing end mills. These general-purpose roughers are designed for high-production metal removal in a wide range of workpiece materials. Most are Titanium Aluminum Nitride (TiAlN) coated, but the larger 2-inch roughers are uncoated.
