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 …

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.

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.

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 ...

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

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.

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.

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.

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.
