The mill rolls take an initial thickness reduction in preparation for the finishing stands, Steel temperature must be monitored to meet parameters and prevent roll damage. Solutions: …
The roughing mill work rolls of many hot rolling mills in the world are faced with the problem of contact fatigue in the bonding and bonding zone before reaching the scrap diameter. This phenomenon is caused by factors such as rolling steel with high resistance to deformation, long rolling cycle, increased reduction in order to increase the ...
THICKNESS REDUCTION: Roughing mill reduces slab thickness in five (5) to seven (7) reversing passes down to 1.125" (transfer bar). ... REVERSING ROUGHING MILL Work …
2. Housing-less Mill Stand Steefo Group's state-of-the-art Housingless mill stand is designed to produce high-quality wire rods, angles, bars, channels and universal beams and can do so seamlessly due to the reliable …
The roughing mill withstood extreme service conditions with long service cycles for backup and work rolls, a large variety of the same width rolling campaigns, severe and non-uniform wear contours ...
In this paper, the spalling causes of backup rolls in a roughing mill of a hot strip rolling mill were investigated. The roughing mill withstood extreme service conditions with long service cycles for backup and work rolls, a large variety of the same width rolling campaigns, severe and non-uniform wear contours of backup and work rolls.
The X-Roll® hot strip mill from SMS group is an all-round talent in hot strip production. It is the proper solution for ultra-thin gauges up to thick gauges for all steel grades incl. LC, ULC, high strength grades, API grades. ...
The line consists of a 4-high reversing roughing mill (R2) equipped with hydraulic gap control and a vertical edger at the entry side (Figure 2). Long-stroke, hydraulic automatic width control (HAWC) is applied to ensure high width accuracy and simple maintenance. ... The Pair Cross mill controls crown by crossing the rolls to achieve a ...
A Roughing End Mill, also known as a ripping cutter, is a cutting tool used predominantly in milling operations. It's designed with multiple serrated cutting edges that disperse the force exerted on the mill, thereby reducing the chip load, optimizing chip evacuation, and minimizing the risk of tool failure.
(1) Semi-continuous roughing mill: It consists of a reversible flat roll frame with vertical roll or a reversible flat roll frame with vertical roll and a reversible flat roll frame. (2) Three-fourth continuous roughing mills: In addition to the above racks, there are two consecutive racks arranged in series.
The rolls in roughing mill R2 withstand extreme service conditions. Figure 2 shows the working conditions of rolls in the roughing mill of the HSM. Work rolls subject
Many hot rolling mills worldwide are facing bonding zone fatigue problems on their roughing work rolls before reaching their scrap diameter. This can be explained …
The roughing mill also contains edger rolls which are used to roll the edge of slab and center it. The hot strip mill can be either a high performance mill or a compact mill. The difference in the two mill types is the coil box which, in compact hot mills, is installed between the roughing and the finishing mill. ...
Mill Configuration REVERSING ROUGHING MILL WIDTH REDUCTION: Slab width is reduced up to two inches with the vertical edging rolls (squeeze). THICKNESS REDUCTION: Roughing mill reduces slab thickness in five (5) to seven (7) reversing passes down to 1.125" (transfer bar). DESCALING: High pressure descale water on …
Block Mill Rolls. Quality of the wire or rod is decided by these rolls. These rolls demand very high resistance to wear and thermal fatigue. Performances of the rolls are determined in terms of tonnage rolled per …
Composition - The typical chemical com- positions of the main rough- ing roll grades used today in hot strip rolling are listed in Table 1. This table indi- cates the main elements such as carbon ...

Every end mill is carefully designed to fulfill demands of high quality, precision, and maximum productivity so you can get the most out of your machining ...
This is becoming common whether a 2-high, 4-high, 6-high, or cluster mill. Before dual motor drives, rolls had to be ground the same diameter. If one roll needs to be ground, the opposing roll must be ground at the same diameter. Four-high mills are very common for steel, aluminum, copper, and any high production metal rolling.
Download Citation | Roughing Mill Work Rolls for Hot Strip Production | In roughing mills, slabs have to be reduced from 200 to 300 mm thickness down to transfer bar thicknesses between 15 and 50 mm.
The roughing mill work rolls of many hot rolling mills in the world are faced with the problem of contact fatigue in the bonding and bonding zone before reaching the scrap diameter. This phenomenon is …
