- the proposed oxidatively safe material has a combination of iron and aluminum oxides in order to be balanced in such a way that Such an acceleration of the dilution of the melt also contributes to the maintenance of profitability.
- the rate of interdependence of alloys from rupture will be less reliable. Otherwise, due to a lack of acid, there will be no complete oxidation of circulation, which may cause hazardous wastes and by-products of the product. If the content of Less than 2 ⁇ 3 and / or Less than 3 ⁇ 4 exceeds 80 wt.%, The total interaction effect will be significant and inadmissible for gas.
- a copy of the offer of the original material was installed in the present part of a large crucible.
- the unit of the industrial sector was equipped with a water-cooled unit.
- a cover with a cold crucible was installed with a tool for setting the speed of the bath, measuring the depth of the bath and observing the furnace.
- the active zone was sold preliminarily from the non-reactive refueling method of the primary crucible, after which the crucible was used.
- the crucible with the alloy was installed on a workstation equipped with a direct drive for the vertical movement of the crucible of the non-ferrous industry and ecana.
- the rate of movement of the interaction component was divided at the moment of contact with the hot alloys of the thermometer, incorporated into the parent material.
