We are supplying HSS rolls to the most advanced Hot Strip Mills in Asia, North America and Australia as well as in Japan, and their performance has been proven in every type of mill such as pair cross mill, CVC mill and CSP mill. The following materials are available for each finishing stands. 1)
#0183;#32;Two types of pinch roll have equal method generating tension is induced by pressing strip between upper roll and bottom roll. Fig. 2 shows the hinge type pinch roll and governing Eq. (I) is expressed by friction coefficient between strip and roll. Fig. 3 shows the housing type pinch roll, it is similar in shape to the hot mill stand. Governing Eq.
The primary function of the conventional hot strip mill (HSM) is to reheat the semifinished steel slabs (rolled or continuously cast) to the rolling temperatures and then to roll them thinner and longer through a series of rolling mill stands driven by large motors and finally coiling up the lengthened steel sheet for its easy handling and transport.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
The strip enters the downcoiler from a pinch roll and is immediately formed around the mandrel using wrapper rolls. Unlike a traditional coiler, a hot strip mill downcoiler utilizes a series of rolls and sensors to maintain tight and well aligned coil wraps. The downcoiler eliminates telping coil sides and irregular wraps on a coil.
Download Citation | Wrapper Roll Control System of Hot Strip Mill | Wrapper roll is one of the most important components in rolling coiler. And it has great relation to the quality of the final
Work Rolls for Hot Strip Mills Gerdau. terface through the console. The second stage, when the strip tail through the last finishing mill and signal from 1 to 0, the speed of mandrel equals the speed of strip which switch from tension control to speed control, the speed of the hot run out table, pinch roll and wrapper roll is less than the speed of strip, the value of lag rate is
Wrapper Rolls are manufactured according to the application conditions with electroslag welding or with thermal coating. Run Out Table Rolls are manufactured in all different executions, starting from T1TC which is a thermal coated roll, to internal cooled run out table roll with strip cladding.
#0183;#32;Requirements of Rolling Mills should be considered: Rolls cost: It represents the 5% of the direct cost of a strip sheet rolling mill and 10% including the operation of the roll workshop. Cost of noquality: The inlaid calamine because of the roll represents 150 000 up to 450 000 /year depending on the type of Hot Strip Rolling Mill.
The Hot Strip Mill represents the most productive solution for flat rolled products. It provides the highest level of productivity together with a large product mix and outstanding quality. Yearly productivity of Hot Strip Mills can vary from 2 to 6 Mtpy, depending on the configuration that is selected.
SMS DEMAG Hot Strip Mills 10 The drumtype shear installed between the roughing and finishing mills of a hot strip mill crops the transfer bar at its head and tail. In special applications, the drumtype shear also serves to divide transfer bars and finished plates. Based on the experience gained from more than 60 drumtype shears built so far,
HOT STRIP MILL HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a
You''ll appreciate XRoll #174; hot strip mills from SMS group as allround plants for highquality hot strip. They are designed to produce flat steel from thin strip with a minimum final gauge of millimeters to highstrength pipe steels up to millimeters thick, including stainless steel grades.
#0183;#32;ThyssenKrupp Steel Europe spent a quarter of a million euros on renovating its hotstrip rolling mill in Duisburg. The animation shows how it all works.
Wrapper roll is one of the most important components in rolling coiler. And it has great relation to the quality of the final products. Based on the programming and optimization experience, a hot strip coiler with new coiling process, which operates with position control and pressure control is introduced.
