Sulfur is a detrimental impurity in molten steel that can easily form long strips or flake-shaped sulfide inclusions, causing a decrease in the transverse compressive strength and plasticity of steel [].In addition, the FeS formed in molten steel easily shapes a low-temperature eutectic at the grain boundary of ferrite and austenite, which reduces the hot workability of steel [].

The sulfur isotope composition of metasedimentary sulfides in sample DT119 ranges from −31.1 ‰ to −21.0 ‰, consistent with the proposed Late-Mesozoic depositional age (between 145 and 66 Ma; Figure 8). In metasedimentary sample K12, δ 34 S values of sulfides fall between −32.4 ‰ and −11.0 ‰.
in the grinding zone28-31. Currently, sulfur compounds are mostly used as additives for cutting fluids32-37 and introduced into the grinding wheel in the form of impregnate38-42. Sulfur-impregnated of grinding wheel is mainly used to reduce the intensity of smearing of the GWAS by workpiece material, thus prolonging its life, and
Method and mechanism for the formation of sulfur compounds during the process of sulfur electrochemical dissolution has been studied, including a technique for the production of composite sulfur-graphite electrode. Along with these, a 3D design is presented in the unit that was used to perform electrolytic reduction, using composite sulfur-graphite electrode.
Natural Gas Composition and Specifications. Natural gas as recovered at the wellhead consists of mostly methane (C 1), but it contains other hydrocarbons, principally ethane (C 2), propane (C 3), butanes (C 4), and pentanes C 5 that constitute the natural gas liquids, as discussed in the previous section. Raw natural gas also contains water vapor, hydrogen sulfide (H 2 S), carbon dioxide ...
4.4.1.25 Sulfur Content. The sulfur content of a crude oil is important for a number of reasons. Downstream processes such as catalytic cracking and refining will be adversely affected by high sulfur contents. If high-sulfur asphalt is oxidized, there is the potential for production of high levels of sulfur dioxide which can lead to acid ...
For grinding wheels for titanium, armored steel, Inconel ®, tool steel, high-nickel alloys and other hard-to-grind metals, get fantastic results with a Tiger Ceramic grinding wheel. These tools take on any metal types and deliver a superior combination of cut rate and wheel life.
A novel process for sulfidation of ZnO by co-grinding with sulfur and reductive additives (P, Fe, Al, and Mg) was developed. The sulfidation extent of ZnO with the addition of P, Fe, Al or Mg can reach 85.2%, 81.6%, 96.7% and 92.6% after grinding for 4, 6, 1 and 1 h, respectively.
Sulfur reacts and forms compounds with all elements except gold, iodine, iridium, nitrogen, platinum, tellurium, and the inert gases. Sulfur is abundant and occurs throughout the Universe, but it is rarely found in a pure, uncombined form at Earth's surface. As an element, sulfur is an important constituent of sulfate and sulfide minerals. It ...
Some grinding wheels receive additional materials that serve as aids to grinding. These include sulfur and chlorine compounds that inhibit microscopic welding of metal particles and generally improve metal-cutting properties. The Manufacturing Process Most grinding wheels are manufactured by the cold-press method, in which a mixture of ...
The chemical and mineralogical characteristics of alumina-containing wastes—catalysts used in the gas processing industry — and the possibility of using them in the charge compositions of high-alumina ceramic grinding bodies were investigated. It was found that this waste is a valuable nonmetallic ceramic raw material and the samples based on it belong to mullite materials for ceramic ...
Sulfur dust ignites easily in air. Grinding sulfur may produce an explosion hazard. Static discharge may ignite sulfur dust. Sulfur burns with a pale blue flame that may be difficult to see in daylight. Burning sulfur will flow and emits large quantities of sulfur dioxide (SO2), a toxic, irritating, and suffocating gas that can cause severe
This method includes triplicate melting steps with excess sodium sulfate, followed by grinding and washing to remove unincorporated sulfur salts. The wash solutions were also analyzed as part of this study. These data will be used in the development of …
