Slag Flow

It can be seen from Figure 1.9.6 that when the mold is ascending, the slag flow is radially outward and will provide a warm current flowing near the shell tip, which will cause reduction in heat flux and possibly some thinning of the shell.

Converter Slag

Carbonation can also reduce the pH of slag (van Zomeren et al., 2011). Thus, carbonation of slag can not only stabilize and valorize slag but also result in the sequestration of CO 2. Different pathways to mineral (or slag) carbonation may be followed (Sipila et al 2

The trouble with ''slag''

 · The trouble with ''slag''. Many of the 20th Century''s most famous performers were not born with the names we know them by. Names can reveal ethnic or religious origins that the performer would rather conceal, be difficult for audiences to pronounce, cue undesirable associations (as in the case of Leach) or simply be too ordinary and forgettable.

Basics of slag production

 · The final slag can have a lime/silica ratio of about 3 or 4, although this can vary substantially from one heat to the next. Depending on the grade of steel being produced, the details of the process for each heat may be governed largely by the target level of phosphorus.

Why Great Welding Needs Good Welding Slag

 · The slag can get trapped in the weld as you build up each layer of the weld. The slag caught in the joint, because it contains oxidized metal and foreign particles can corrode over time causing your weld to fail early. 2. Again in multipass welding not overlapping the welds sufficiently.


 · Although slag inclusions are most commonly associated with submerged arc welding, flux-cored arc welding and stick welding, they can also transpire in MIG welding . Weld slag inclusions can lead to corrosion in the weld joint. This can weaken the weld over a while.

Defects / Imperfections in Welds

This can be done between runs by grinding, light chipping or wire brushing. Cleaning tools must be identified for different materials eg steels or stainless steels, and segregated. When welding with difficult electrodes, in narrow vee butt joints or when the slag is trapped through undercutting, it may be necessary to grind the surface of the weld between layers to ensure complete slag removal.
