slag
The penetration has a relationship with the separate distribution of slag on the weld surface.
      
Then, an observation of scanning electron microscopy (SEM) and an electronic data systems (EDS) analysis of slag were performed respectively.
      
The separate distribution of slag on the weld pool during welding and the great constriction of arc spots were confirmed by TIG welding with helium shielding gas.
      
The relationship between slag distribution and weld penetration was studied by adding aluminum powder into flux AF305 to change the distribution of slag.
      
During welding, the separate distribution of slag on the weld pool results in the great constriction of arc spots, an increase in arc spot force, and an increase in Lorentz force within the arc and weld pool.
      
Using a test rig with a capacity of 640 MJ/h with an absolute milling system and flue gas online analysis system, characteristics such as burnout, slag, and pollution of some blended coals were investigated.
      
The ratio of coke and slag as a method of distinguishing coal slagging characteristic was introduced.
      
When temperature was over 1,100°C, more than 99.9% of the dioxins could be decomposed and most of the heavy-metals could be solidified in the slag.
      
It is shown that the higher the slag basicity, the stronger the hydration interactions in alkaline binder compositions causing their hardening, all other things being equal.
      
Such flows are realized when slag cotton is obtained by the action on a molten mineral of the centrifugal force of drums rotating in the vertical plane [1].
      
A Model Description of the Thermochemical Properties of Multicomponent Slags and Its Application to Slag Viscosities
      
The model description is also used in linking thermodynamic data with slag viscosities.
      
Water vapor dissolution in the slag melt model introduced in the paper is based on polymer theory.
      
A Study of the Process of Gold Recovery from a Slag Melt into the Bottom Phase in Fire Assay
      
Procedures have been proposed to estimate the recovery of gold from a slag melt into the bottom phase without using a lead collector and the size of particles settling naturally to the bottom phase.
      
The possibility of the rapid and efficient direct analysis of solid samples with the use of a hollow-cathode pulsed glow discharge was demonstrated using an example of the analysis of high-purity copper samples and the glassy slag of molten lead.
      
The regularities of the redistribution of strengthening additive phases, as well as fusible slag inclusions, during the fusion of composite coatings based on self-fluxing alloys are investigated.
      
The distribution coefficients of the metals between copper and slag were determined and compared with the results of other investigations.
      
Such defects as cracks, lack of penetration, lack of fusion, porosity, and slag in welds and pressure vessels could be diagnosed via this technique.
      
A changeover from purely resistive slag conditions to electric arc conditions for an electroslag process is explained.
