Alumina magnesia refractory is the main refractory material for lining purging plug and nozzle of steel refining ladle while the CaO Al 2 O 3 SiO 2 slags can cause their great damage during service In this work in situ corrosion process visualization of the Alumina magnesia refractories were carried out by preparing high temperature resistant speckles on its
The Centrifugal atomization process finds wide application in the production of sprays & droplets [] as well as polymer microspheres [] dry slag granulation [3 4] metal powder production [5 6 7] is an increasing demand for powders and granules as a form of starting material for several industrial applications such as architectural coatings additive
Steel slag which is the slag discharged from the steel making process is a type of solid industrial waste Steel slag consists mainly of calcium iron silicon magnesium and small amounts of aluminum manganese and phosphorus oxides According to the National Bureau of Statistics of China in 2021 China produced more than 100 million
The bearing capacity of silt soft soil is poor making it difficult for it to be used as a subgrade material in foundation engineering and the use of traditional Portland cement curing agents causes environmental pollution In this study a new soft soil curing agent CSP ceramic powder slag phosphorus slag was prepared using ceramic powder slag and phosphorus
Steel slag is the main solid waste generated in the steel making process accounting for 15 to 20% of crude steel output [1] China s crude steel output in 2021 was billion tons [2] more than half of the global crude steel output billion tons [3] and the steel slag output exceeded 120 million contrast the comprehensive utilization rate of
The preparation of the SS sample can be divided into the following 8 steps as described in Fig 1 a Firstly about 5 kg of coarse SS aggregate was selected from 100 kg SS aggregate hill and then the selected SS aggregate was crushed and ground in a ball mill for 60 min and sieved with 200 mesh sieve to obtain the SS powder which could ensure the
Due to the low hydration activity and poor volume stability extensive steel slag utilization is restricted In this paper the hydration process and microstructure of alkali activated materials with steel slag as a cementitious material and fine aggregate were studied The phase composition and micro morphology of hydration products were measured using XRD NMR
A novel conversion of Ti bearing blast furnace slag into Ti containing zeolites Comparison study between FAU and MFI type zeolites May 2022 Advanced Powder Technology 33 5 103559
Steel slag is a by product produced by the conversion of carbon rich molten iron into steel in basic oxygen furnaces BOFs and electric arc furnaces EAFs during the steelmaking process accounting for about 15 to 20 wt% of the crude steel production [1] The global steelmaking industry produced billion tons of crude steel in 2019 and China alone
Lithium slag is industrial by product of the extraction of lithium carbonate industry which is produced by high temperature roasting of spodumene and sulfuric acid [1] [2] [3] For each tonne of lithium carbonate 8 to 10 tonnes of lithium slag will be discharged [4] [5] Xinjiang and Sichuan in China are the most major lithium salt production bases and
The micro crystalline glaze on mineral powder modified coal gangue was carefully peeled off with a carving knife and tweezers and ground into powder for FTIR and XRD analysis Functional groups of the micro crystalline glaze were detected by FTIR spectra IR Prestige 21 FTIR Shimadzu Japan using KBr pellets after 32 scans at a resolution of
