A Study of EAF High-Chromium Stainless Steelmaking Slags ...

A good slag practice is essential for production of a high-quality stainless steel. In addition, the electrical and material efficiency of the electric arc furnace (EAF) can considerably be improved by a good slag practice. The metallurgical properties of the slag are strongly influenced by …

Properties of ten-year-aged argon oxygen decarburization ...

The characteristics of argon oxygen decarburization slag (AODS) for smelting stainless steel that has been aged for 10 years were analyzed. Three types of AODSs distributed at three positions in a slag heap were sampled for comparison experiments. Chemical analysis, mineral phase identification, thermogravimetric analysis, and micromorphology analysis …

The utility model belongs to the technical field of bottom slag treatment for coal-fired generating set and particularly relates to a bottom slag conveying device for a large-slag-quantity power plant. A slag conveyer is arranged at the bottom of a boiler, the head part of the slag conveyer is arranged at the outer side of a boiler room, a slag bin is arranged under the head part, and the slag ...

Hard Black Slag On Stainless Steel Weld - Welding Tips and ...

Hi Everyone, New to the forum. I am not a welder myself, However I am trying to get to the bottom of an issue we are having with stainless steel welding, I have attached a few photos, What we are experiencing is an almost impossible to remove black slag / residue included in the weld, it only becomes apparent after pickling and passivating.

Properties of ten-year-aged argon oxygen decarburization ...

In 2019, China produced 29.4 million tons of crude stainless steel [], accompanied by more than 9.0 million tons of stainless steel slag [].Three kinds of stainless steel slags are produced in the three processes of smelting stainless steel, namely, electric arc furnace slag (EAFS), argon oxygen decarburization slag (AODS) and ladle metallurgy slag (LMS) [].

INCINERATION BOTTOM ASH - STEINERT

In the >20 mm fractions the sorting of stainless steel content in IBA ash is economically of interest. Here the STEINERT ISS® induction sensor sorting unit, with the selective ARGOS-type induction sensor, can be set up for outstanding separation of stainless steel from incineration bottom ash.

melt-in. The partition of phosphorus in the slag to phosphorus in the bath ranges from 5 to 15. Usually the phosphorus is reduced by 20 to 50 % in the EAF. Sulfur is removed mainly as a sulfide dissolved in the slag. The sulfur partition between the slag and metal is dependent on slag chemistry and is favored at low steel oxidation levels.

Eliminating slag time in plasma cutting - The Fabricator

Two employees were needed in the plate cutting area for each of the 10-hour shifts: one to operate and load/unload both plasma cutting machines and another to deburr the parts. Because the plasma cutting produced plenty of slag (see Figure 2 ), the employee responsible for removing it with a hand grinder had a very taxing job each shift.

In order to improve the recycling efficiency of stainless-steel slag resources, the effect of different cooling rates on the crystallization behavior of CaO-SiO 2 -MgO-Cr 2 O 3 based system was ...

Non-Metallic Inclusions in Steels - Slag Inclusions

MnO slag in steel MnO x SiO2 x Al2O3 inclusion in high carbon wire rod steel MnO-SiO2, MnO-Cr2O3 inclusions in AISI 304 stainless steel MnO-rich inclusions in Orvar 2M steel MnS and Ca-Si-Ti-Al inclusions in AISI 316 steel MnS and spinel inclusions in steel MnS inclusions in grade-X steel MnS inclusions in steel with Sn I

Reducing headaches associated with slag on laser grating

A lack of slat maintenance also can cause minor headaches. Slag buildup can cause the molten material to bounce back onto the bottom of the material being laser-cut. That produces a marred appearance and a need for rework, where none is typically expected. For a fabrication operation working with stainless steel for food or medical applications ...

The state-of-the-art example of steel slag usage as an aggregate in concrete pave- ment is a situation in Belgium where slag from stainless steel production is used as an aggregate in roller ...

Stainless Steel Melt Practices - Clinton Aluminum

The process is used to remelt and refine stainless steel into high-quality ingots. An electric current is passed through a consumable electrode of the subject material. The electrode tip melts into a pool of molten engineering slag at the bottom of a copper baseplate.

Effect of stainless steel slag waste as a replacement for ...

Conversely, mortar samples with a low mechanical strength and material durability are located at the left-bottom quadrant, including mortar mixes with a 30% replacement ratio (S30), showing a clear distinction between mortar mixes crushed stainless steel slag waste (Sw-C) and burned stainless steel slag waste (Sw-B) (Fig. 10B).
