60000 tons of phosphorus slag powder technology and stainless steel Classifying iron and steel for import and export GOV.UK Stainless steel is defined as alloy steel containing, by weight, 1.2% or less of carbon and 10.5% or more of chromium, with or without other elements.
Granulated phosphorus slag is made up of regularly shaped and angular particles, mostly between 4.75 mm (No. 4 sieve) and 0.075 mm (No. 200 sieve) in size. It is more porous than air-cooled slag and consequently has lower specific gravity. Granulated phosphorus slag is more vesicular than air-cooled slag and consequently has lower unit weight.

Separating Slag From Molten Iron(fe) Patents and Patent . Jun 11, 2004Abstract A Method for the recovery of the secondary metallurgy (LF) slag from a plant for the production of steel, the method comprising a cooling step of the slag, by means of the passage of air and/or other gas, a breakdown step, a step of extracting the powder, wherein the breakdown step is accelerated by means of forced ...
03-06-2020· As a result, the amount of required slag/ton of steel can be decreased. However, the phosphorus content in the metal is slightly increased. The replacement ratio of FA will be limited by the acceptable phosphorus level in the final steel, due to higher phosphorus content in FA from pulp and paper mills compared with that in PL.
26-03-2021· The slag generated by the steel plant has been utilized to produce submerged arc welding flux. The flux produced by recycling steel slag has been applied in the submerged arc welding process. The effects of recycled slag on the chemical composition, microhardness, and microstructure of weld metal have been evaluated. For chemical composition, weld pads were prepared and beads on plates …

phosphorus material flow in Japan including iron and steel industry has been investigated based on the sta-tistical data on 2002. It has been demonstrated that phosphorus in the steelmaking slag is almost equiva-lent with that in the imported phosphate rock in the view points of the amount and the concentration. Phos-
phosphorus slag powder production line of stainless steel. Molten Metals Rolled Alloys, Inc. Skimmers for removing slag from ladles of molten brass or copper are mild steel, 430 stainless (16.5%Cr, balance Fe) and, more likely, RA446. All of the austenitic alloys will fail rapidly in contact with molten copper or copper alloys. Get Price
06-11-2017· In sintered as well as cast steels presence of phosphorus is a problem as it induces brittleness in the steels and deteriorates the mechanical properties. The present research work describes a P/M route to produce ductile iron phosphorous alloys. Alloys with phosphorus contents 0, 0.35, 0.65, 1.3, 2, and 3 wt.% were developed by a powder forging route.
Steel is still produced using technology derived . ... tonne of crude steel. of slag is produced per tonne of crude steel. In the electric arc furnace, around ... Recycling one tonne of steel . scrap saves 1.5 tonnes of CO 2, 1.4 tonnes of iron ore, 740 kg of coal, and 120 kg
15-01-2018· 1. Introduction. China is full of phosphate and the total storage is only after Morocco in in the world .According to statistics, 8–10 tons of phosphate slag will be produced with the average production of 1 ton of yellow phosphorus.China produces nearly 900 million tons of phosphate slag every year, resulting in serious waste of land resources and groundwater pollution, .
