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:how to divided the external wall thermal insulation materials fire rating
The external wall thermal insulation materials is divided by fire rating: 1. The thermal insulation material of level A combustion performance: inorganic fiber spray coating, glass wool, foam glass, foamed ceramics, rock wool, foam cement and hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:which is better as household fireproof material ?
If it is from the perspective of fire rating inorganic active insulation material for wall thermal, cement foam insulation board, glass beads of insulation movitrified micro bead thermal insulation mortar, rock wool board, glass wool board, ect.. thermal insulation material are Class A fireproofing, polyphenyl board, extruded sheet, phenolic foam board, Polyurethane board, ect..belong to B1 level fireproofing, if it is used for external wall thermal insulation in decorative board, then rock wool board is more often used.
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:Who knows what kind of material the fire-proof plate use, and is it good?
Personally speaking, fireproof clapboard is very good. It is also known as fire-proof plate or fire retardant board. Made by the pressing of a variety of incombustible materials after scientific deployment, it is good in fire retardation and can be fire resistant for over 3 hours. It is also non-toxic and non-detonating with high mechanical strength, water and oil resistance, and good chemical corrosion resistance.
Q:How long is the fire endurance of Grade A fire resisting shutter
Based on national standards GB 14102-2005 specifications. It is specified in GB 14102-2005 provides that: The fire resisting shutter whose fire endurance is not less than 3h is AAA fire resisting shutter when the unexposed surface temperature rise is used as judging condition. Therefore, it is required that the fire endurance of Grade A fire resisting shutter is 3h.
Q:What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?
Hello steel structure can adopt surrounding concrete or brick, fireproof coating, fireproof board coating and composite structure for its fire resisitance. Fire resisitance board can be divided into thick fire protection plate and thin plate, the thickness of the plate thickness of the fire is between 20 ~ 50mm, mainly includes calcium silicate fireproof board and expansion boring stone fire board, the main varieties are KB board, CF; thin fireproof plate is between 6 ~ 15mm thick, the main varieties include enforced short fiber cement plate, ordinary enforced fiber silicate calcium board and glass cloth reinforced inorganic board.
Q:What are the fire protection standards of insulation materials?
This question is, like this. The combustion performance of thermal insulation materials for exterior walls of all civil buildings, within the scope of fire design auditing and fire control acceptance, should be brought into the auditing and acceptance. As for the "Management Regulations on Supervisions of Fire Prevention and Control for Building Projects" (Ministry of Public Order No. 106) , all civil buildings which are out of the scope of Article 13 and 14 are included in the random check. Before the release of new standard, it must be strictly implemented the Article II of the "Fire prevention Interim Provisions on civil external wall insulation system and external wall decorative" ([2009] No. 46), namely, the insulation materials of civil buildings must use materials with A-level combustion performance.
Q:Is the ball mill used in production of refractories?
It depends on what refractory you produce.
Q:How to divide the fire resistant level of construction thermal insulation materials?
1, Combustion performance of the national standard building materials are divided into the following levels: Class A: incombustible building material: Material that almost never burn. Class B1: nonflammable building material: Nonflammable materials have good effect of flame resistance. In case of fire it in the air or at high temperature it is difficult to catch fire and spread, and when the fire source is removed, the combustion can stop immediately. Class B2: combustible building material: Combustible materials have good effect of flame resistance. In case of open fire in the air or at high temperature, it will immediately burst into flames and spread the fire quickly, such as wooden column, timber roof truss, wooden stairs, etc. Class B3: flammable building material: No flame-retardant effect, highly flammable, high risk of fire. 2, According to fire rating, external wall thermal insulation materials can be divided into 1) thermal insulation material with class A combustion performance. Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite,etc. 2) thermal insulation material with class B1 combustion performance: Extruded polystyrene board (XPS) after special treatment /polyurethane (PU) after special treatment , phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) thermal insulation material with class B2 combustion performance: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:Can anyone tell me what is a high alumina refractory?
High alumina refractories: High-alumina refractory products have high refractoriness, compressive strength and refractoriness under load, which are used for building the high-temperature parts of various large blast furnaces, such steelmaking furnace, airheater, electric furnace, rotary kiln and other thermal equipment.
