We try to do our best Thanks.

Thank you very much!

which countreu is that?

Thank you for your interest. Please find below answers to your questions: 1) Yes, the float process ensures perfect flatness for both the ribbon and final panes. 2) Flatness is addressed within the bow and dish requirements of our internal float glass manufacturing specification. We do not make our manufacturing specifications publicly available, but we confirm that Pilkington Optifloat™ meets the requirements of the European Standard, EN 572-2. 3) Standard available sizes: jumbo size 6000 x 3210 mm, LES size 3210 x 2550 mm. 4) If we say the ribbon is formed in the bath and a typical bath is 60 m long, the annealing lehr to cutting is ~180 m, then yes 250 m is typical for a continuous flat glass ribbon, but there is some variation between the manufacturing plants.

I work downstream birmingham.

do you know Thomas Shelby ?

Kimberly Locklear what's the longest pane of glass poured onto molten tin? From what I found at their website is a bath that's just under a half mile.

The use of lead could help in radiation shielding. For heat retention (inside the building) the glass would be coated with low emissivity coating. More information is available on our website: www.pilkington.com/en/global/about/education/glass-in-buildings/energy-saving

Thanks!

Bryan C Multiple backup systems are in place. For electrical power loss, conveyors, computers, and ADS machines have battery backups that immediately take over to maintain function until backup generators can be powered up. All backup systems are tested monthly and well maintained. For loss of natural gas there is a contingency plan using liquid fuel turned to aerosol using compressed air. For loss of water cooling we switch to city supplied water. If city water fails, there are multiple water towers with a backup supply.

you can also use an LPG/Air mixer that combines propane with air to match the Wobbe Index of natural gas. This can be used as a direct substitute to natural gas.

@@timmay6545 So is it rare to lose a batch and have to recycle it all?

@nickallen13 once the furnaces are fired up they operate 24/7 non-stop for years, we try to get over 15 years out of a furnace... transitioning between colors or when problems arise like water leaks in the furnace, the glass produced is busted and stored to be "salted in" and recycled based on color/composition... it is much easier to melt the broken glass (cullet) than it is to melt raw batch, so we always run using a variable percentage of cullet. Our goal is to minimize fuel consumption and run the furnaces as efficiently as possible, so the "loss" is never truly a loss... so it is technically common to lose batches, but it is necessary and it is all accounted for and used in future batches to reduce fuel consumption.

That's correct. The cutting wheel travels a diagonal line across the glass because the glass is moving underneath.

PilkingtonTV right, so how do diagonal cuts suddenly become rectangular pieces?

The movement looks and is diagonal but the cut is perpendicular to the edge of the glass. Imagine if the movement was perpendicular to the edge of the glass and the glass was moving then the cut would be diagonal.

Hi, the packages are moved throughout the warehouse with special vehicles, so called glass frame transporters (Hubtex) to prepare the goods for dispatch to our customers. Some of the packages are brought to the storage area by cranes. Thanks.

tin will only fuse to the glass if the tin starts to oxidize. having pressure and a mixture of gases to create a atmosphere prevent the fusing of the two

@@TheShadeManGuitar Thank you.

David Hughes Hot glass is above it's Tg temprature - it won't break off, it would tear with plastic deformation which would spoil the edges and deform areas around them. But yes, the sooner they are broken off the warmer they are, thus saving costs.

The glass needs to be annealed before it can be scored and broken out. It is still quite warm though from the annealing process. By the time the knurl (ridged part made by the top roll machines) is scored and broken away from the ribbon it needs to travel by conveyer back to the batch house before it is sent along with the batch over to the furnace where it sits in a bin where it is gravity fed into the furnace. Almost impossible to contain and recycle the original heat.

did you ever get one

I've worked as a glassmaker at Pilkington's rolled p!are and electric furnace float line. It is very much science from their Latham scientists and working experience from their workers. Working the glass, getting it down the lehr and cutting it correctly is passed on from more experienced workers and learned from making mistakes. It's like driving a 50 tonne truck on an icy road, and one small mistake can ruin the process for hours, days , weeks.or.months.

You need to check with glass melting furnaces producers. Thanks.

you did see it. 4:33
