The 12 best pedalboards 2021: top choice pedalboards

2021/4/14The Pedaltrain Nano is a compact, soft-cased board that accommodates only a single row of pedals, but it's a great option if that's all you need and you're craving a tidy solution. Because of the tight space under the board, you'll have to raise the rear feet by DIY means, or buy a specific compact

A comparison of the family of AlTiB refiners and their

There are a number of grain refiners based on the AlTiB system used in DC casting. These vary in both concentration and Ti:B ratio. An in depth experimental program has been performed to compare the effectiveness of some of these refiners in DC casting. One of

ACD / Aluminium Compact Degasser

How it works The ACD / Aluminium Compact Degasser is a multi-stage, sealed in-line rotary degassing equipment that processes molten aluminium using spinning nozzles directly in the casting trough between the furnace and the casting pit. The ACD is much smaller and flexible than conventional in-line degassers (with refractory‑lined steel boxes). Although the physical, mechanical and

Comparison of the RH and tank degassing processes

The results show that in more than 80 % of the cases the optimal degasser choice, whether it is RH or VD, is clear. This choice is typically made on the basis of the type of melting furnace, the production program, the metallurgical operations and targets, and according to the metallurgical background and experience of the customer.

Hydrogen gas porosity

Hydrogen gas porosity is an aluminium casting defect in the form of a porosity or void in an aluminium casting caused by a high level of hydrogen gas (H2) dissolved in the aluminium at liquid phase. The solubility of hydrogen in solid aluminium is much smaller than in liquid aluminium. As the aluminium freezes, some of the hydrogen comes out
