the steckel mill is a reversing rolling mill in which steel strip is coiled after each rolling pass in a heated coilbox positioned on either side of the mill. In addition to the lower capital costs associated with a single stand mill in comparison to multi-stand finishing mills, the steckel millsteckel mill is a low cost hot rolling mill. the other type of hot rolling mill is tandem mill where there are several stands in tandem and reduction takes place one after another. investment and space requirement is more in case of tandem mill. In the steckel mill, several passes have to be taken to get the desired reduction.
the steckel mill process differs from the traditional rolling by the presence of coiler furnaces in either side of the rolling stand, as illustrated in fig. which reheat the strips while investment cost or msw ball mill; investment cost of steckel mill; morocco particular mill investment; investment cost secondary crusher mining; barite grinding mill plant investment; investment for stone crusher; investment to start crusher; how much investment required to start small scale stone crusher; stone crusher plant investment
In the end of april 2002 outokumpu made an investment decision to increase the production of its steckel mill from the level of million ton to 1.7 million ton of stainless steel. To attain this drastic increase in production, it was the first time in the history that three additional finishing stands were installed after an steckel mills are the proven solution for coil production up to 1.5 mtpy and at the same time represent the most cost-effective choice within the large hot rolling mill family. recent innovative solutions applied to modern steckel mills make it possible to achieve high-quality strip that is comparable to the products of traditional hot rolling
various types of steckel mills by siemens-vai are shown below. one stand steckel mill for plates and coils rolling. engineered volume of production 1..2 mln tons a year. cast broad slabs are rolled in steckel stands with a bigger length of rollers barrels on a plate rolling mill set up in the middle of the of the XX century in china.for economy of operation, as much as possible of the total length of a steel strip being rolled by a steckel mill should be maintained at an acceptably high temperature. To this end, the trailing edge of the strip is drawn into the coiler furnace to the extent possible without losing driving control of the strip. this is enabled by providing within or in close proximity with the entranceexit

nov 10, 2020 steckel mill generally is classified upon product specification, that as rolling mill working roll body length, defined into small typed mill, heavy duty rolling mill, and large mill. In the steckel mill, several passes have to be taken to get the desired reduction. the steckel mill has quality problems due to temperature losses.steckel furnaces reheat the metal, keeping it pliable, reducing edge cracking and surface oxidation. plus, coils greater than 600 piw can be produced easily. the hot rolling steckel mill is also equipped with automatic gauge controls, a shape control package and a laminar flow cooling system to maintain gauge, shape and optimal metallurgical
correcting distortion by lapping or grinding decreases the case depth. As with induction hardening 4140, carburizings low tempering temperature of to can lead to soft spots and rapid wear. In selecting gear spindle material, mill operating conditions, desired spindle service life and cost must be taken into consideration.for any new investment, the challenge is to design the plant such that it remains flexible to produce a wide range of products to cater for future demands. siemens vais latest references include a unique combination of plate and steckel mills into a single line and a new plate- steckel mill plant.
