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 detect the acid resistance of refractory? Is there any standard? Thank you
There is a standard. However, the range what you said is a little big, it's difficult for me to say. But though the scope is a bit big, it should be: You can check the industry standard network, to see whether you can check it.
Q:Who knows the highest temperature the high-temperature refractory coating can resist?
The fire endurance of high temperature fire resistant coating is 3 hours. The fire endurance of fireproof is to go on fire resistance test of any building component according to the time- temperature standard curve, which is the period of time started from being put on fire and ended when losing support function or integrity has been destroyed or losing fire insulation function, expressed in hours. I hope my answer can help you. Thank you.
Q:How much is the duration of fire resistance of the porous brick shale?
It depends on its formula since the highest temperature varies from formula. For example, the temperature of common bricks is 900℃, if the lime in it accounts for most part, then the temperature could reach 1050℃; if coal ash accounts for over 40%--50%, then the temperature could amount 1050℃--1150℃.
Q:Who knows about roof fireproofing materials?
Roof water proofing materials: synthetic polymer waterproof rolls, high polymer modified asphalt waterproof coiled material, sheet metal, synthetic polymer waterproof coating, one-component water curing polyurethane waterproof coating, penetration crystalline waterproof coating. Secondly, we have to choose materials that are suitable for roof water proofing. The right waterproof materials have better waterproof performance, TS-3B one-component water curing polyurethane waterproof coating is very suitable and the performance is good. Since traditional roof waterproofing materials have requirements on the moisture content of the formation level which should be less than 9%. It is really important to choose which materials to repair leaking roofs. Kitchens and toilets are moisture, the formation levels of buildings are hard to satisfy requirements, thus, waterproof layer and formation level are easily get separated and are ineffective in waterproofing.
Q:I am a manufacturer of refractory materials. I would like to receive some orders from abroad. I would like to know what foreign trade companies in Dalian place foreign orders abroad
Dalian foreign trade companies are numerous, and fire prevention materials are also quite a lot
Q:What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?
The main material is quartz sand and it is the cheapest, and can resist 1500℃ without any difficulty.
Q:What are the raw materials of refractory concrete ?
Q:Refractory material, refractory brick
1, according to the degree of refractoriness:Ordinary refractory material: 1580 ~ 1770 DEG CAdvanced refractory material: 1770 ~ 2000 DEG CSuperfine refractory material: >2000 DEG C2, depending on the shape and size of the product:Standard type: 230mm * 113mm * 65mm;No more than 4 measurements, (size ratio) Max:Min<4:1;Profile: no more than 2 concave, (size ratio) Max:Min<6:1;Or an acute angle of 50~70 degrees;Specific type: (size ratio) Max:Min<8:1;Or not more than 4 or a sharp angle; 30 ~ 50 degrees;Special products: crucibles, vessels, tubes, etc.3, according to manufacturing methods, refractory materials can be divided into:Fired products, unfired products, unshaped refractories4. classification according to the chemical properties of materials:Acid refractory material, neutral refractory material, basic refractory material
Q:Who knows what kind of fire prevention materials are there?
1, Fire-proof board Fire-proof board is the most frequently used materials in the market. There are two kinds of fireproof boards which are commonly used; one is the high pressure decorative board, which has the advantages of fire prevention, damp proof, abrasion resistance, oil resistance, easy cleaning, and more variety of colors and designs. The other one is a glass magnesium fire board, the outer layer of which is a decorative material, the inner layer of which is a mineral glass magnesium fire material. It can resist 1500-degrees high temperature, but not suit for decoration. The installation of fireproof ceiling in the exit passageway, stair well and corridor can ensure safety evacuation, and protect people from the spread of the fire. 2 Fire-proof door Fireproof door is divided into wooden fire proof door, steel fire proof door and stainless steel fire proof door. Usually the fire proof door is used for the opening of the firewall, the entrance to the staircase, the evacuation of the aisle, the openings of the pipeline and other parts of the building, and it has an important role in fire separation and reducing the loss from fire. 2 Fire resisting shutter I hope it may be helpful to you.
Q:Are the rubber insulation materials are refractory materials?
Compared with the fireproofing properties, the main thermal insulation properties of level B1 will be carbonized and drop when it is over 200 degree.
