Q:Use of carburizing agents
In the smelting process, due to improper ingredients or improper loading and excessive decarburization, the carbon content in the steel sometimes does not meet the requirements of the top stage. The commonly used carburizing agents include carburized pig iron, electrode powder, petroleum coke powder, charcoal powder and coke powder. When smelting medium and high carbon steel in converter, the oil containing little impurity is used, and Jiaozuo is used as carburizing agent. For BOF steelmaking using recarburizer requirement is high to low fixed carbon, ash, volatile matter and sulfur, phosphorus, nitrogen and other impurities, and dry, clean, moderate size.
Q:Why can graphite powder conduct electricity?
Graphite is a crystalline mineral of carbonaceous elements. Its crystalline framework is hexagonal layered structure. The distance between each network layer is 3.40, and the distance between the carbon atoms in the same network layer is 1.42A. Of the six Fang system with a complete lamellar cleavage. The cleavage surface is mainly based on molecular bonds, and has weaker molecular attraction, so its natural floatability is very good.
Q:What mask should be used to prevent stone powder?
As an enterprise employee, we must actively advocate the right of labor protection to the enterprise owner, and the stone powder can be worn with industrial masks
Q:What are the specifications of the graphite powder used for conduction?
Graphite powder itself is conductive, according to purity, particle size, conductivity is also different
Q:Can graphite powder be found in plastic?
Graphite powder can be used in plastics, plastics are not resistant to wear, high temperature, acid and alkali corrosion, plastics are widely used in industry
Q:What binder does the graphite powder form with?
Graphite powder is divided into natural graphite powder and artificial graphite powder, graphite powder made of graphite products, you need to add binders, binders useful for a variety of resins, asphalt and so on. 100~200 C is not called high temperature for the preparation of carbon graphite products, but only resin can be prepared at this temperature.
Q:Does graphite allow lubrication of rusted doors?
Tolerable。 However, there is a premise: rust must be removed with rust.Lock force rust is generally not easy to lock inside the material easily rust off, then need to use oil to rust, rust removing, the graphite powder filling hole, and then the key to rotate back and forth, you can make the door lubrication.
Q:Will dust explosion occur in graphite dust? If you have definite or negative judgment, please share it according to data.
Any object that is crushed will have a surface energy (internal energy), but the temperature will not increase, so the specific heat will become largerFuel burns because its energy is already full (reaching a point of fire)When the object reaches the ignition point, internal energy = (ignition +273.15) * specific heat capacity
Q:Why does the temperature rise when the graphite powder is turned on?
But one thing will not change. Graphite powder is one of the best nonmetallic conductive materials. As long as the graphite powder is kept inside the insulating object, it will electrify as a thin line
Q:Crystal graphite of graphite powder
Pure graphite flake graphite and high directional pyrolytic graphite, which have less defects and larger sizes, can generally be considered as perfect graphite single crystals. Considerable research has been done on the thermal conductivity of such graphite. Under compressive stress, the pyrolytic graphite above 3000K processing, the bulk density is 2.25g/cm, 2.266g/cm is close to the theoretical density of the single crystal, the half width of the diffraction peak (002) show only 0.4 degree angle (mosaic angle), is also very close to the theoretical value of zero. The thermal conductivity of this graphite is shown in table 1. These values are generally considered to represent the corresponding values for single crystal graphite. The thermal conductivity along two principal directions is denoted as lambda a along the layer, and is marked by lambda C along the vertical plane.
