Abstract This paper is concerned with the study of the processes of melting volcanic rock in a cold-crucible induction furnace in order to obtain a high melt bath and study its degassing. The results of experiments carried out to assess the thermal stability of the melt, determine its energy characteristics, and study the melt behavior at a current …
1500 ℃ (glass melt point varies between 1400℃ and 1600℃). Opaque basalt absorbs rather than transmits infra-red energy unike gass whch s tr ansparent. Use of overhead gas burners used in conventional glass furnaces is more difficult for uniformly heat the entire basalt mix. With overhead gas, the melting basalt must be held in the reservoir
Inductotherm Vacuum Induction Melting (VIM) Furnaces are designed specifically for operation in high vacuum environments and include vacuum-adapted construction methods and the industry's most advanced coil …
Consequently the melting basalt must be held in the furnace for extended periods of time to ensure a homogenous temperature. Attempts to promote uniform basalt heating include immersion of electrodes in the bath. However there is a preference for gas heating despite increased manufacturing costs. An alternative two-stage gas heating scheme ...

Once at the furnace hot-spot, the basalt fraction fuses as a drop on the wire loop. The maximum size of mineral grains in the pulverised basalt is 5 #m and Donaldson (1979a) has shown that complete ... of the basalt melt is 220, 370, and 560 poise, as computed by the method of Shaw (1972). At the Po~ used losses of Fe to the wire and ...
This article suggests the design of a melting furnace, since the melting process is the most energy-intensive in the production of fiber. The article provides a list of heat engineering principles necessary for creating an energy-efficient furnace, such as the maximum heating of basalt by waste gases, Gorenje fuel directly in the basalt melt ...
Basalt fibre is a type of continuous fibre prepared from natural volcanic rock and ore after melting at high temperature. The raw material for basalt fibre (andesitic basalt, andesite basalt, diabase and other volcanic rock) belongs to the family of inorganic nonmetallic silicates and is characterized by high Fe 2 O 3 or FeO content. The high Fe …
As derived from the new data and the enthalpy of. vitrification measured at 973 K by oxide-melt drop. solution calorimetry for the same sample, the enthalpy. of fusion of this basalt increases ...
The electric basalt melting furnace is used for liquids, and it is naturally used to warm theiquids at a temperatures below 2186% Crystius. With electric basalt melting oves, the heating power is used to heat the liquids, rather than the liquids. There are also heating power supplies, the second basalt melt oven is the portable type that allows ...
Basalt glasses and fibers with different homogenization times were prepared as follows: The basalt raw materials were heating from room temperature to 1400 °C by an MXX1700-50 high-temperature melting sample furnace and then maintaining at that temperature; The melts were homogenized in the furnace chamber for 0, 5, 10, 15, 20, …
