Heat resisting bushing feeders (further - feeders), are intended for reception coarse fibre,
thin and superthin glass staple fibres from rocks at temperature up to 1350 °Ñ.
- Feeders correspond to requirements of specifications and the working drawings approved when due hereunder.
- Key parameters and the sizes
- With one-piece a bushing plate:
- Bushing plate, consisting of a plate and welded wings.
Feeders by quantity bushing correspond to the requirements, presented table,
and in the sizes - resulted on figures 1 and 2.
Characteristics of feeders
Table
| Type of a feeder | Quantity of forming apertures, (bushing), pieces | Diameter of forming apertures (bushing), mm |
| Value | Extreme deviation |
| For thin fibres | 1-5 | 4 - 10 | ±0,5 |
| For superthin fibres | 220-350 | 1,8 - 2,5 | ±0,05 |
| For coarse fibres | 12-100 | 3,0 - 5,0 | ±0,1 |
Figure 1
In coordination with the Customer manufacturing feeders of other sizes, and
also feeders without apertures with processing apertures at the Customer is supposed.
3.1 The bushing plate of a feeder is made of the heat resisting alloy providing
following the operational characteristics:
- Temperature of bushing weeding not less + 1300 °Ñ
- Term of operation not less than 500 hours
- The chemical compound, structure and heat resisting properties of an alloy are
guaranteed by manufacturing techniques.
3.2 Wings and a current contact jaws of feeder are made from high-alloy steel of mark 12Õ18Í9Ò in accordance with ÃÎÑÒ 5632.
COST:
In coordination with the Customer feeders without current contact jaws or preparations
for manufacturing feeders (heat resisting plates in the size can be delivered: 290õ90õ12 mm and 420õ80õ12 mm).
