SiMn Powder 614 Certificate:SGS/CIQ/ISO 


siliconmanganese alloy is an alloy made of manganese, silicon, iron and small amounts of carbon and other elements. Silicon manganese alloy is used as compound deoxidizer, also reducing agents of the production of low-carbon ferromanganese and manganese silicon thermal power production. Manganese and silicon are the main alloying elements in the steel. Manganese is one of the main deoxidizers in steel-making process, further more, almost all kinds of steel are required to use manganese deoxidation. Because when deoxidize with manganese to generated oxygen products with low melting point, easy to rise; Manganese also increases strength of silicon and aluminum deoxidation effect. All industrial steel are to be added a small amount of manganese as a desulfurization agent, the steel can be hot rolling, forging and other processes without breaking, manganese, or the most important types of steel, the alloy elements in the alloy is also added 15% Mn above to increase the structural strength of steel.

Q:Which kind of furnace hearth refractory is better?
Coal is acidic medium, so the matched material should be acidic refractories oriented, like silica bricks. For example, the coking coke oven and carbon furnace made of carbon are in reducing atmosphere, so they use silica bricks which have low price and good high-temperature indicators. If the part has special requirements, you can then consider other refractory on request.
Q:What kind of refractory materials are used in metallurgy industry?
Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.
Q:What is the fire endurance of fireproof glass cotton?
The highest temperature of fireproofing glass wool can be above 200 degrees, so it can be used for a long time,it's difficult to judge the special usage time, but its usually about 3 months and 8 hours every day.
Q:Refractory materials are needed for casting metallurgy.
Refractory material used in foundry work is that refractories for cupola furnace? Cupola is a high temperature furnace which is used for melting molten iron, and refractory material adopted is mainly low iron high grade clay brick and clay lightweight insulation bricks, etc.foundry ingot refractory material is pearl sand (also known as pearl jewelry sand, fused ceramic, ceramic sand) it is made of high quality bauxite material by arc melting furnace.
Q:What is glass furnace used high-grade refractory materials?
It is said that building a furnace need 30 million? After the ignition, it can't be gone out. Only at the waste to maintenance?
Q:Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?
1.The insulation materials with A-level combustion performance: EPS Hairong module, rock wool, glass wool, foam glass, ceramic foam, foam cement, closed-cell perlite, etc. 2. The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powder particles,etc. 3. The insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene boards(XPS), Polyurethane(PU), Polyethylene(PE), etc. See the 2009 measures of building technology. The A-level insulation material is only fireproof, the insulation performance of it is worse than that of organic XPS \\\\ EPS material. Currently I think that the best insulation material should be Hairong EPS module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range.
Q:Who knows what is the standard of insulation material whose fire proof is level A?
Level A is distinct from B in coefficient of fire proofing. Level A is non combustible, while Level B is divided into B1( flame retardant), B2(combustible) and B3( inflammable). Currently in the market, level A materials are as follows: phenolic, rock wool, insulation mortar, ceramic foam, foam glass, and foamed concrete. The most advantageous of level A material at present is foamed concrete, also known as foamed cement. Xuzhou Lvchuang Construction company is working on this, you can search fro it on the internet, it has high cost performance.
Q:What's the heat conductivity coefficient, specific heat capacity and density of the refractory material of magnesite-chrome brick and magnesia-alumina brick respectively?
It is suggested that you find some samples of well-known manufacturers, such as Ogilvy and Mather Group, and that will be more correct.
Q:What does the function of SiC for refractories?
The main feature is with high temperature, the wear gold resistance of refractory is recognized by our customers. Hope my answer will help you.
Q:Who know about the knowledge of acid refractory material? Please explain in detail.
