In this research, waste slag generated by steel plant is recycled as a useful flux for submerged arc welding. It is found that recycled slag is capable of producing acceptable weld bead geometry. The penetration achieved using recycled slag is mm, which is more than the penetration obtained using fresh flux, mm.
TBRC is an advanced smelting equipment for treating anode slime, WEEE, nonferrous metal smelting slag and setting slurry to recover gold, silver, other precious metal and rare metal. It can also treat copper concentrate and secondary material like scrap copper, scrape lead, lead slag, lead dust, etc.

This "Flux Slag" can now be crushed (reprocessed) into a reusable SAW consumable. The flux / slag crushing program at Harbert''s consists of the following: 1. A manufacture of the slag ships a *LOT of their slag to Harbert''s. 2. The slag is received and is inspected for **deficiencies, and / .
The flux used in SAW generates wastages known as Slag. It is generally thrown away as a waste after use. This poses the problem of storage, disposal, and environmental pollution and needs landfill space apart from exhaust of nonrenewable resources. The flux is very costly and if by recycling...

Jul 11, 2018· The objective of this testing was to classify the recycled slag as an F7 A2EM12 K, which means the testing of the coupon welded with the recycled slag will produce weld metal with an aswelded tensile strength no lower than 70,000 psi (480 MPa) and Charpy Vnotch impact strength of at least 20 ftlb (27 J) at 20°F (29°( ) when produced with an EMl 2K electrode under the conditions ...
The successful development of recycling technology that allows the use of slag as a fresh flux will surely overcome the abovementioned problems and will also prove to be very economical. Slag was processed by replenishing it with suitable alloying elements/deoxidizers by agglomeration. This replenished slag is referred to as recycled slag.
Sep 16, 2019· The use of synthetic fluxes in secondary steelmaking not only improves the properties of top slag and steel quality but also increases the production cost. Ladle furnace (LF) slag can be used as a replacement to synthetic fluxes owing to its chemical and mineralogical compositions. Valorization of LF slag helps in sustainable steelmaking and also reduces steel production cost.
The chemical composition of weld pads prepared using pure crushed slag and fresh flux and recycled slag is recorded in Table 2. Fig. 1: Weld metal pad for chemical analysis (ASME ) TABLE 1 CHEMICAL COMPOSITION OF ELECTRODE AND BASE METAL Carbon Manganese Silicon Sulfur Phosphorous Electrode
Oct 11, 2007· Slag generated during conventional submerged arc welding (SAW) has been recycled by mixing varying percentages of crushed slag with fresh flux to use in subsequent runs. The influence of using fluxslag mixture on various aspects of SAW weld parameters of bead geometry have been investigated in a quantitative basis. Slag has been reprocessed and reused in submerged arc welding .
code requirements, recycled slag can be reliably used as an alternative to fresh flux. They further claimed a saving upto 50% of the total cost of purchased flux by recycling the slag. Motivated by their concept, Singh et al. 5 found that recycled slag can produce acceptable bead geometry. As a continuation of the study, Singh et al. 6 further
The objective of this paper is to investigate the utilization of Submerged Arc Welding (SAW) slag as a fresh flux for sustainability. Certain alloying elements were added to the crushed slag to adjust the resultant composition of the weld metal as per American Welding Society (AWS) and operational characteristics such as arc stability.
slag. The BF slag accounts for about twice the amount of BOF slag, and the SMP slag is relatively less significant in terms of utilization due to the lower generated amount. Roughly BOF slag, EAF slag and SMP slag can be defined as steel slags. Reviewing the past, utilization of ironmaking slag .
(5) SAW flux is nonbiodegradable or renewable; this is a construction material that is brittle and glassy. Recycled steel slag, the material that will not stop being produced as long as there is steelmaking. This is a material that can be a option instead of using SAW flux. For slag to be added to filler wire it has to be processed and modified.

In the present study the effects of process parameters and recycled slag on flux consumption has been studied. Methods/Analysis: The experiments were conducted using fractional factorial design with type of flux (fresh flux/recycled slag) as one of the controllable factors. Mathematical model for flux consumption was developed.
