The refractory products does resist to high temperatures and are used for realising and maintenance of blasts, high furnaces, steel bags, furnaces, burners, opened-fires, pipes, outlining walls for structures where heath keeping and high temperatures resistance are needed.
Depending on use , different qualities are offered to warrant the bests conditions of appliance. The 'LY' label allows to identify easily our products and a supplementary code-number shows for the standard products the alumina density. This number reveals if the product does perfectly apply to the special needings and material cost.
This is a sample list of the existing needings in solid refractory products :
- covering standard or shaped bricks,
- bauxite bricks, sillimanite or corindon,
- bagging bricks,
- non-stop leak splitter bricks,
- bricks for mixers,
- outsourcing leaks bricks,
- tiles, disks, refractory masses, ...
and for the hollow products,
- pipe-shaped, with or without joining possibilities,
- ferrules,
- craters,
- bends,
- T-shaped
- disks, ...
Every kind is dedicated to a particular use. The hollow products are generally used in steelworks industry, insteed of the solid products which are used in all the sectors where refractory is required.
- Thermic or chemical linkage
The refractory products are all ceramic products and are traditionally baked to force ceramising. The used linkage is mainly clay that enhances homogenicity of the product during ceramising time. It happens that some other linkage technics, non-ceramical or part-ceramical gives results conforming to special applications. In this situation, we use then chemical linkages, like for example phosphoric acid or its derivated to manufacture "raw" products.
- Standard or shaped products
These products which conforms to accurate Belgian, French, Dutch, Italian and European norms, ... are called standard products. The common refractory bricks in Belgium measures 220x110x60 mm, in France, the NF1 measures 230x114x64 mm, the NF2 250x123x64, in Holland, the classical bricks measures 212x105x55 mm, etc ... The cementry dedicated products are more standard-sized at European and even Extra-european level. The common hollow products are more generalised at European level. Anyway, every kind can be manufactured regarding special shaped or measures. In this case, the mould designing costs are charged, insteed of for the standard products, which for the moulds and types exists and doesn't need any special design. It is anyway prossible to create and own your own moulds in our stock for your usual kinds of bricks. In any situation it could be useful to put yourself in contact with our sales department.
- Anti-Acid, P.C.T., Penetration, ...
In order to meet special needings, some special mixtures are offered to warrant some complementary qualities to the refractory products, like the "anti-acid" treatment, ...
- Dry overpressed or stretched products
Excepting some limited hollow products that are manufactured by stretching, called "wet way", all our products are for long time ago manufactured using dry way, meaning dry overpressing, in automatic presses for the standard products and great series or manual presses for small series or special shaped products.
