Tin Bath Blocks

In the float furnace tin bath DSF are one of the leading suppliers of tin bath block with the material DSF CTB. DSF CTB is unique in the market, a cast material with a low cement bond, it has low diffusivity in combination with low permeability. This is extremely difficult to achieve, but also extremely advantageous for our customers ensuring trouble free glass production. DSF also offer sillimanite and calcium aluminate tiles for the tin bath roof.
DSF CTB is used by most of the major float glass producers including AGC, Guardian, NSG and Saint-Gobain, a stud hole ram can also be supplied; DSF CTB Ram

Mullite Regenerators

DSF’s mullite offer for regenerator design has become standard in the industry as glassmakers have moved away from basic and silica refractories. Typical recommendations have been established after many years of evaluation and testing. DSF 59 is a 55% alumina, 80% mullite material predominantly used for rider arch applications. DSF Frisil G is 58% alumina and 83% mullite, this is used in rider arches, adaptor courses and chimney blocks. DSF Frisil H is 63% alumina and 90% crystalline mullite, this is a essentially a mullite brick used in a wide range of applications including the upper regenerator walls and crown, transition courses and sometimes in rider arches. DSF Mullite ML31 is 70% alumina and 97% mullite, this unique high fired material is used in target walls, regenerator crowns and upper regenerator walls. A 99% alumina material, DSF 99, can be used as a protection layer for the checker pack.
Intermittant kilns are used at DSF to ensure full mullitisation of our range of regenerator andalusite and mullite materials, ensuring optimum stability and superior chemical resistance.
