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 structural properties of refractory materials provided by the manufacturer of the refractories include?
Metal oxides have very good resistance to high temperature, such as: three, two aluminum oxide, Magnesium Oxide...
Q:What are the materials of white firebricks?
The commonly-used firebricks include alumina bricks, corundum bricks, chamotte bricks, high alumina bricks, diatomite bricks, zircon bricks, lightweight corundum bricks, zirconia bubble bricks and so on ~~~
Q:What are the disadvantages of the refractory industry?
The rapid development of continuous casting technology allows Hua Heng refractories to be improved in variety and quality. The development of refractory for continuous casting has a significant impact on the production of continuous casting and quality of continuous casting billet. Constructing and putting Baosteel into action has greatly pushed the improvement of the refractory technology. Continuous casting refractory is an important part of the continuous casting machine. In addition to the general characteristics of refractories, it is also required functions that can purify molten steel, improve the quality of steel, stabilize temperature and composition of the molten steel, control and regulate the molten steel flow. Therefore, it is known as functional refractories. Continuous casting Refractories include: (1) ladle refractory - ladle lining, permanent lining and ventilation components; (2) tundish refractories - permanent lining, coating, insulating plates, clad etc; (3 ) functional refractories - long nozzle for non-oxidizing casting, submerged nozzle, monolithic stopper, sliding gate; (4) ceramic purifier for purifying molten , slag dam, alkaline paint and horizontal separating ring and gate board for continuous casting.
Q:How to choose refractory material
Refractory fiber according to different raw materials, there are aluminum silicate, quartz, alumina and graphite, refractory fiber. Commonly used aluminosilicate refractory glass fiber is amorphous, including ordinary aluminum silicate fiber, high-purity aluminum silicate fiber, chromium silicate fiber, long-term use temperature of 1000-1200 degrees.
Q:Who can tell me the properties and classification of insulating refractories?
Insulation materials can be classified according to service temperature, production process and application fields.
Q:what is the Specifications Grading for Fireproof rubber insulation materials ?
External insulation materials, welded wire mesh matt external wall insulation, external wall thermal insulation mesh matt. 1,inorganic activel thermal insulation materials 2,silicate thermal insulation material 3,ceramic thermal insulation 4, gelatine powder polyphenyl granule, 5,teel wire gauze picking cement cystosepiment(Estazolam platepowder particles)6 extruded sheetXPX. 7,Rigid polyurethane coating at the scene, Polyurethane insulation board8,rigid polyurethane foam,9EPS foam board roofing materials. 1, a ceramic insulation board 2, xps extrusion board 3, perlite and perlite brick 4, vermiculite and vermiculite brick heating, air conditioning Material: Phenolic resins, polyurethane waterproof thermal insulation integration, sponge rubber, polyethylene, polystyrene foam, glass wool, rock wool Steel material: Polystyrene, extruded sheet, polyurethane panels, glass wool carpets and the like. Five inorganic thermal insulation materials: Foam cement, DY inorganic active insulation system super thin vacuum insulated panel for building external walls .
Q:What's the requirements of fire-fighting criteria of heat insulating material?
It shouldn't be under than B2 level. Roofing insulation fire rating requirements: the ministry of public security, housing and urban-rural development department issued about printing and distributing the civil building external thermal insulation system and the interim provisions on the exterior wall decorative fireproof prescribed in the notice: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm.
Q:What are the main components of refractory cement?
SiO powder is often used. Ultra-fine powder refers to less than 1 / zm particles which are made by hydrolysis of ethyl silicate or made from recycled dust in the smelting process of ferro-silicon alloy. Non-cement castable refractory are castable refractory material which contains no cement instead it relies on the coagulation and combination by adding ultra-fine powder or sol (see refractory castable), and it is an amorphous material with high activity. Silica sol is made through Ion-exchange of sodium silicate after Na ions are removed. The easiest method is to prepare by reaction of aluminum metal with hydrochloric acid or alchlor. It is a thermodynamically unstable system which has certain requirements for ultra-fine powder and sol. It is different from non-cement refractory castable, Cr2zrOz and etc. It has low impurity content, and can bond with itself, so it has good binding strength. Ultrafine powder used in non-cement castables are SiO2, Al2O3, Cr2zrOz, etc. Such recycled SiO2 powder has an average particle diameter of 0.5 pm, therefore when adding the gelling agent (electrolyte), it can coagulate and give the products some bonding strength. Non-cement castable refractory is made up of refractory aggregate and powder and it is round. Since the use of superfine powder or sol as binder. The size of sol particles are of 0.1 ~ 1 m. Non-cement refractory castable takes oxide or synthetic compound ultra-fine powder or oxide sol-gel which is similar to the chemical composition of material in tungsten castable. There are several ways to prepare alumina sol. The sol used are mainly alumina oxide and silica sol. The surface area is large, and it helps to improve high-temperature structural strength. Non-cement castable refractories rely on oxide ultra-fine powder or sol to coagulate and combinate. It is a refractory castable (also known as chemical bonding castable) which uses chemical binder instead of cement for combination.
Q:Is there requirement for radiation indicator in refractory?
All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.
Q:What are the advantages of refractory material?
