Product Description

Steelmaking Deoxidizer Silicon Carbide Replacing for Ferro Silicon

As the new alloy for converter, Si-C alloy can replace Ferro Silicon to be used as deoxidizer.

Characters: lower steelmaking cost, increase economic benefit, improve product quality and stable performance.

Steelmaking Deoxidizer Silicon Carbide Replacing for Ferro Silicon

Si-C:

1. Replace Ferro Silicon

2. Reduce the alloy quantity

3. Improve the quality of liquid steel (reduce carburant )

4. Lower production cost

Q235	MnFe+FeSi+ SiAlBaCa+Carburant	MnSi+Si-C+SiAlBaCa

How to Use?

HRB335: During tapping, add SiMn Alloy when the liquid steel tapped about 1/3, at the same time, put Si-C gradually to the steel ladle.

Q195: During tapping, add SiMn Alloy when the liquid steel tapped about 1/3, then SiAlBaCa, at the same time, put Si-C gradually to the steel ladle, and feed wire at argon blown station.

Q235: During tapping, add SiMn Alloy when the liquid steel tapped about 1/3, then SiAlBaCa, at the same time, put Si-C gradually to the steel ladle.

Chemical Compositions:

	Si (%)	C (%)	Ca
Si-C	56±1	17±1	/

Advantages:

1. Si-C can replace Ferro Silicon and Carburant to do the deoxidation alloying.

2. Using Si-C instead of Ferro Silicon will help to improve the quality of steel.

3. It will helps to lower the cost, gain profit and strength the competitive advantage.

From the above form, we can get the result that using Si-C alloy can help to improve the qualification rate.

Mechanical Property Comparison:

From the above forms, we can get the conclusion that, the mechanical property of the test steel, which has used SI-C, can be much more stable.

After using SI-C alloy, the average tapping temperature has been improved 9℃, and the average temperature drop has also increased 6℃.

We can see from the data that, using Si-C alloy can helps to save cost about 4.787RMB.

Q:What are the main materials in concrete fireproofing material?: fireproofing materials mainly consist of class A incombustible?material and class B1 nonflammable material. Class A incombustible?material: Granite, marble, terrazzo, cement products, concrete products, gypsum board, lime products, clay products, glass, tiles, mosaics, steel, aluminum, copper alloy; class B1 nonflammable material: Ceiling materials, dry wall, fibrous plaster.

Q:What are the requirements of refractory temperature of refractory brick?: Refractoriness can reach 1690 degree, but the highest operating temperature is 1350 degree. If the temperature goes higher, operation life will be greatly shortened.

Q:what is the common materials for home fireproofing material?: 1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion

Q:What's the refractory material in common use currently?: According to its category, raw material of basic refractory: Mainly magnesite (magnesia), dolomite, lime, olivine, serpentine, high alumina material (sometimes neutral); main neutral raw material: chromite, graphite, silicon carbide (artificial).

Q:which kind of material is chosen for fireproofing window?: Firstly, fireproofing window glass must be tempered, ordinary glass won't play a role of fireproofing, and fireproofing window fan is fixed, can't be open, if you can open it, it won't play a role of fireproofing. And you can ask the property to provide texture report of fireproofing windows, fireproof material stipulated by our national fire protection laws and regulations must have fireproofing inspection reports, there must be. and fire window glass should have a fireproofing sign. The main role of fireproofing window is to isolate the fire, and play a role of fireproofing and escaping, avoid the fire quickly spread in.

Q:Which company needs the new refractories?: The power plants are mainly used in steel plant, lime kiln, coking plants, boilers, etc. I will try my best to answer what I can. There are too many glassworks. You can tell me more anout what you need. As long as there is a large kiln business, the refractories and aluminum manufacturer are needed.

Q:Fire resistance and evaluation of refractory for casting: The products to be tested are broken and ground, adding organic binders (usually dextrin) that do not affect the refractoriness. Water is used to make standard sized test cones, as shown in figure 1-2-1. Test cone is positive, three edge cone, the bottom side length of 8.5mm, the top side length is 2mm.Test, the equivalent of high standard cone refractoriness of the 2 products to be high, No. 1 and No. 1 high temperature low standard cone of each one, and the 2 to be tested in accordance with regulations frustum cone plug made of high aluminum material, a cone prism and vertical 8 degrees. 1 degrees tilt angle. Then, the cone is heated in a high temperature furnace. When the test cone with a high temperature and bending down to the standard cone top contact cone, the high standard cone refractoriness refractoriness is running.

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:How is the performance of refractory materials?: It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project

Q:I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??: I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire?retardant. The wholesale of all kinds of thermal insulation material and construction need to look at the name, hope you adopt.
