Also, what are the bad side effects of doing this?<\/h4>\n<p>Yes, the lower line speed helps to reduce the white stripes. However, very accurate movement and heating control are needed to prevent localized glass temperature differences. Too slow line speed at the end of the heating cycle can increase roller wave and edge kink.<\/p>\n<h4>What is the recommended transfer speed from a furnace to chiller for 6-mm coated glass?<\/h4>\n<p>Typically, the recommended transfer speed for 6-mm coated glass is around 300\u2013400 mm per second. Thinner glass needs faster transfer speed than the thick glass.<\/p>\n<h4>What temperature do you recommend having your furnace at before stopping the rollers?<\/h4>\n<p>To be sure that there is no material weakening of the rollers, we recommend that furnace temperature before stopping the rollers is about 300 \u00b0C.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This week, we are dealing with these three questions: Is it possible to eliminate the white stripe by lowering the line speed in the furnace to 50 mm per second?
