The MagDryLine tundish lining products are designed to get the most out of every tundish. A comprehensive range of binders and base materials allows products to be tailored precisely to customer requirements.
The MagDryLine tundish lining method developed by Bet-Ker Oy covers the critical aspects of customer processes and the composition of the product is tailored accordingly. Choosing the right base material will minimise heat loss during the casting process and choosing the right binder will minimise the critical impurities in steel. MagDryLine lining products can be installed on hot, warm and cold surfaces. MagDryLine is patented by Bet-Ker Oy. The MagDryLine concept includes tundish wear linings, backfill materials, tundish furniture and lids, as well as installation equipment.
MagDryLine wear lining
MagDryLine Hot Setting
The MagDryLine dry lining mix is dry-set between a mould and the backfill material. The bond is formed by either heat from the backfill material (200–500 degrees) or with a heated mould. For the best energy efficiency, tundish availability and lining surface quality, we recommend the use of backfill heat.
The MagDryLine base material can be olivine, magnesia or an olivine-magnesia blend. The choice of base material will determine the thermal efficiency of the tundish in continuous casting processes.
We have a wide selection of inorganic, organic and hybrid binders to match customer requirements for the critical impurities in steel.
Clean, pure steel (with the appropriate binder)
The lowest hydrogen and carbon pick-up on the market
No sulphur pick-up
No phosphorus pick-up
Good thermal efficiency
Materials can be installed in hot tundishes!
A correct choice of base material reduces the heat loss of steel in the tundish process
MagDryLine mixes do not stick to moulds, making them pleasant to install compared to mixes with organic binders
Quick and easy deskulling after use
MagDryLine mixes are odour-free to install
MagSprayLine wear lining
The Bet-Ker Oy tundish product family includes the MagSprayLine wear lining for gunning. Like the MagDryLine products, the base material of MagSprayLine mixes can be selected according to customer requirements to cover tundish heat loss, material performance in high temperatures and critical impurities. MagSprayLine products can be installed on hot or cold surfaces by using different manual and robotic sprayers.
Cost-effective tundish lining
Can be tailor-made for the customer's process
Multiple base material options
Easy to install with manual or robotic sprayers
Magic wear lining
Magic Cold Setting
The Magic wear lining screw mix needs no separate heat source for bonding. Unlike most cold-setting materials on the market, Magic does not require a heap of added chemical components – all that is needed to form the lining is a little water added to the screw. The Magic tundish lining is dust-free to install, a clear advantage that makes for a comfortable working environment.
Like the MagDryLine dry mix, the Magic products can use olivine, magnesia or a blend of the two as the base material.
The binders for Magic products include inorganic and hybrid options.
Clean, pure steel
Low hydrogen pick-up compared to the other cold-setting materials on the market
Installation is free of dust and odours
Stable lining with quick and easy skull removal
The backfill mixes of the MagDryLine concept include multiple base material options, so that every tundish can have the right material. The backfill mixes produced by Bet-Ker Oy are highly resistant to wear and thermal shock, ensuring a long life for the lining and minimising the consumption of wear lining material, reducing the total cost of the tundish process.
The Cruiver hopper allows material to be injected in a tundish in roughly 30 seconds.
