This paper studies the blast furnace slag glass phase structure by a series of analysis methods. In glass phase, both Si and Al ions are confirmed to occupy only tetredral sites, while the [SiO4]4 and [AlO4]5 are separated by Ca and Mg. Furthermore, the glass structure corresponds to microcrystal model, which means it contains some nanoscaled microcrystals in the glass phase.
The present paper investigated the process of the slag wool fabrication using high temperature blast furnace (BF) slag modified by coal ash (CA). The liquidus temperature and viscosity of the slag system with different mass ratios of BF slag and CA were measured through an inner cylinder rotation method. The approximate mass ratio used to fabricate the slag wool was therefore determined and ...
The molten slag shield in liquid form, so reduce the oxidation of metals. In this weld the clean weld is formed, so no cleaning required for after welding. Which process having continuous addition of slag not required; Defects such as porosity, undercut, notches, and slag inclusions are not encountered. No edge preparation. High production.
The main components of the slag are SiO 2, CaO, Al 2 O 3, MgO, and TiO 2. The content of TiO 2 in the blast furnace slag is %; therefore, it is a low and medium Tibearing blast furnace slag. According to the composition of the slag, this slag is suitable for the preparation of CMAS glassceramic.
The invention discloses a preparation method of dioctyl phthalate (DOP). The preparation method comprises the following steps: adding the raw materials including phthalic anhydride and superfluous isooctyl alcohol to a reaction kettle, adding concentrated sulfuric acid as a catalyst, controlling the temperature in the reaction kettle to be 0150 DEG C, reacting for 1620 hours, neutralizing ...
area cleaned, blasting time, and the abrasive consumed, environmental performance of coal slag and garnet was evaluated. Simple mathematical models were developed to predict performance based on feed rate and blast pressure. Garnet was observed to be more productive, less consuming, and more environmentallyfriendly compared to coal slag.
In this paper, slag is used as a calcium source to make alkaliactivated coal gangue–slag (AACGS) based material. The reaction mechanism of AACGS materials was discussed in depth by means of XRD, FTIR, 29 Si MASNMR (nuclear magnetic resonance) and SEMEDS (energy dispersive spectrometer). The experimental results show that coal gangue can be used as a raw material for preparing alkali ...

Common issues that can weaken a butt weld are the entrapment of slag, excessive porosity, or cracking. For strong welds, the goal is to use the least amount of welding material possible. Butt welds are prevalent in automated welding processes, such as submergedarc welding, due to their relative ease of preparation.
