Pinch Rolls D. D. Rhodes Xtek INTRODUCTION PINCH ROLLS comprise an entire family of non-reducing rolls that are used to redirect the travel of a strip mill product and to provide strip tension for a downstream process. Pinch rolls are used in nearly all the metallic strip producing industries including steel, aluminum, brass and bronze.
GW | PREMCO-ES electroslag built-up welding technology has been successfully applied for years. The advantages are the same as for the submerged-arc strip cladding. Also, there is less fusion penetration of the base material. Due to modified energy input for fusion an even less dilution of the base material is achieved.

roller mill is operated with the rolls out of tram or out of parallel, significant thrust loads may be exerted on the rolls and bearings. In machines with straight bore bearings, the forces may be enough to cause the rolls to shift sideways in the machine, even contacting the mill frame.
Pinch Rolls Bemcalloy TM Pinch Rolls • Hypoeutectic Alloy Gray Cast Iron • Alloy additions: Silicon, Nickel, Chromium, Molybdenum and Niobium Horizontally centrifugally cast • Austenitized, Quenched and Tempered Resistance to Pickup Pickup is a condition whereby foreign material becomes adhered to the surface of the pinch roll during service.

Kenny Wilson, Rolling Mill Superintendent, LONE STAR STEEL COMPANY see what our customers are saying "We came to PRG as we were having considerable hazing problems and build-up on our number 3 paper machine's hot calender roll - spending hours every month cleaning the roll before changing paper grades.
A strip mill roll shaft failure was investigated. The investigation revealed that the fatigue strength of the shaft had been compromised by a combination of several factors that included: inadequate fillet radius size, the use of dissimilar filler materials to rebuild the shaft surface, the presence of slag inclusions at the weld/alloy interface, and machining defects on …
On double pinch machines, the top roll position is fixed and the two lower rolls move in a straight path or an arc toward the top roll. 4 roll versions can accurately roll metal to tighter diameters and can do it in one pass through because the metal is always held by the pinch roll while the 3rd and 4th rolls take turns curving the metal.
The top pinch roll is the hollow structure, consisting of barrel and mandrel. The bottom pinch roll is a solid foging roll. Our engineers will make the production process based on the feature of both pinch rolls. It will ensure that top pinch roll has good welding quality and precise assembly, and it also will ensure a high forging ratio to ...
Three Kinds of Steel Surface Defects. ISO 8501-3, "Preparation of Steel Substrates Before Application of Paints and Related Products", sorts defects into three categories: • Welds. • Edges. • Steel surfaces in general. When inspecting for defects, pay close attention to welded joints, cuts, punctures and scoring.

Cracks can develop over time after the weld has been subjected to loads while in service. Tensile and fatigue loads; bending, twisting, or flexing; as well as hot and cold expansion and contraction all can occur long after welding, be it two days, two months, or even two years. The major cause of a crack is when internal stresses exceed the ...
Many hot strip steel mills around the world are realizing the benefits of the Xtek Bemcalloy™ Pinch Rolls.The inherent lubrication property of the graphitic constituent in the Bemcalloy™ material, along with the natural resistance to adhesion of dissimilar metals, is the basis of the pickup resistance of the material.
2. Three-High Rolling Mills: In this mill, the three rolls stand in parallel one by others. The rolls are rotating in opposite directions. In this mill, between the first and the second rolls, the material passes. If the second roll rotates in a direction then the bottom roll rotates in another direction.

In rolls of winding equipment in a hot-rolling factory, each roll includes a lower cladding layer formed on the surface of the roll barrel and a self-fluxing alloy layer formed on the lower cladding layer by thermal spraying and containing carbide particles dispersed therein. The lower cladding layer includes an Fe-based cladding layer which has a Shore hardness of 60 or greater and …

Surface mill scale is the result of the manufacture of hot rolled steel. Light mill scale is best tackled with a grinder complete with a grinding disc or a flap disc. Once mill scale is removed from where you want to weld, there is no need to wipe down with acetone. You are free to go ahead and weld with your welder. Used Mild Steel
The mill is designed to process low-carbon steel billets with a square cross-section of 150 x 150 (160 x 160 in the future) millimeters and length of 9 meters. This results in rebars with diameters of between 8 and 40 millimeters. In two-slit rolling mode, the bar diameters from 8 to 20 millimeters can be realized.

There are usually visual indications of wear on the grooves of the rolls if replacement is necessary. Also, make sure that the drive roll tension is set properly. To check tension, disconnect the welding input cable from the feeder or switch to the cold feed option. Feed the wire and pinch it as it exits the gun with the thumb and forefinger.
3 Roll Bending Machine Working Principle. Roll bending machine has also been called rounder and roller machine, which is universal forming equipment for rolling metal plate into the cylinder, cone, curved and other shapes. According to the principle of the three-point forming circle, the relative position change and rotational motion of the ...
The core can be manufactured with stainless steel weld as hard-facing and the shell chrome-plated, both to minimize the corrosive wear inherent in the temperature controlled application. As with nearly all of Xtek's forged steel rolls, specialty rolls, and other specialty products, reconditioning and repair services are available.
