Our company developed these systems and they are controlled by modern computers.<\/p>\n

The central idea here is the stationary roll: Heating and quenching units are mobile while the roll does not change its position.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_single_image image=”2885″ img_size=”full”][\/vc_column][\/vc_row][vc_row tm_bgimagefixed=”” css=”.vc_custom_1632133656312{padding-top: 24px !important;padding-bottom: 37px !important;}”][vc_column width=”1\/2″][vc_single_image image=”2803″ img_size=”490×282″][\/vc_column][vc_column width=”1\/2″][vc_custom_heading text=”HARDENING” font_container=”tag:h3|font_size:24px|text_align:left|color:%23014480|line_height:28px” google_fonts=”font_family:Poppins%3A100%2C100italic%2C200%2C200italic%2C300%2C300italic%2Cregular%2Citalic%2C500%2C500italic%2C600%2C600italic%2C700%2C700italic%2C800%2C800italic%2C900%2C900italic|font_style:300%20light%20regular%3A300%3Anormal”][vc_column_text]he benefit of Steinhoff\u2019s hardening is that the time between the cessation of heating and the commencement of quenching is minimised. This means that it is no longer necessary to increase temperatures to compensate subsequent cooling, which in turn means that it is possible to create an optimum microstructure in conjunction with the maximum achievable hardness.<\/p>\n

Our balanced combination of austenitising temperature and time is of great importance to the properties of a high-performance roll.[\/vc_column_text][\/vc_column][\/vc_row][vc_row tm_bgimagefixed=”” css=”.vc_custom_1632133656312{padding-top: 24px !important;padding-bottom: 37px !important;}”][vc_column width=”1\/2″][vc_custom_heading text=”TOTAL BARREL HARDENING (TBH)” font_container=”tag:h3|font_size:24px|text_align:left|color:%23014480|line_height:28px” google_fonts=”font_family:Poppins%3A100%2C100italic%2C200%2C200italic%2C300%2C300italic%2Cregular%2Citalic%2C500%2C500italic%2C600%2C600italic%2C700%2C700italic%2C800%2C800italic%2C900%2C900italic|font_style:300%20light%20regular%3A300%3Anormal”][vc_column_text]It is possible to achieve the balanced distribution of tension and an even progression of hardness across the entire barrel length through the application of classic hardening methods. A lower proportion of austenite and a high proportion of undissolved carbides remain. The computer-guided temperature control makes it easy to reproduce barrel hardening on a wide variety of roll types and barrel shapes thus making it possible to achieve highly homogeneous structures and hardness profiles.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_single_image image=”2887″ img_size=”full”][\/vc_column][\/vc_row][vc_row tm_bgimagefixed=”” css=”.vc_custom_1632133656312{padding-top: 24px !important;padding-bottom: 37px !important;}”][vc_column width=”1\/2″][vc_single_image image=”2888″ img_size=”490×282″][\/vc_column][vc_column width=”1\/2″][vc_custom_heading text=”INDUCTION HARDENING” font_container=”tag:h3|font_size:24px|text_align:left|color:%23014480|line_height:28px” google_fonts=”font_family:Poppins%3A100%2C100italic%2C200%2C200italic%2C300%2C300italic%2Cregular%2Citalic%2C500%2C500italic%2C600%2C600italic%2C700%2C700italic%2C800%2C800italic%2C900%2C900italic|font_style:300%20light%20regular%3A300%3Anormal”][vc_column_text]We employ induction hardening in a targeted manner to broaden the range of our heat-treatment performances.\u00a0<\/span><\/p>\n

We are very proud of our ability to partially harden almost any section of the journals to satisfy customer requirements and the ability to adapt hardening depths to demands through the application of variable frequencies.<\/p>\n

Advancing induction hardening is used not only particularly on rolls that cannot be drilled but also for secondary-hardening materials. It is our main goal\u00a0 <\/span>to meet the demands made by the highly variable roll geometries and fulfil the high standards of quality that apply to hardening. This we achieve by self producing the inductors.[\/vc_column_text][\/vc_column][\/vc_row][vc_row tm_bgimagefixed=”” css=”.vc_custom_1555074547434{padding-top: 0px !important;padding-bottom: 37px !important;}”][vc_column][vc_column_text]<\/a>1<\/span>[\/vc_column_text][vc_custom_heading text=”MECHANICAL PRODUCTION” font_container=”tag:h1|font_size:48px|text_align:center|color:%23014480|line_height:56px” google_fonts=”font_family:Poppins%3A100%2C100italic%2C200%2C200italic%2C300%2C300italic%2Cregular%2Citalic%2C500%2C500italic%2C600%2C600italic%2C700%2C700italic%2C800%2C800italic%2C900%2C900italic|font_style:300%20light%20regular%3A300%3Anormal”][vc_custom_heading text=”The same high requirements apply to mechanical production as to our heat treatment.
