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 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's the varieties of fire-proof sealing material?
ATD-AB, organic fire-proof caulking, fire retardant bag, fire retardant net, fire retardant ring, fire barrier wrap, fireproofing sealing strip, flexibility fireproofing coiled material, fireproof glue, etc., fireproofing sealing materials currently on the market can be divided into two types, one is the traditional type: flexible organic caulking, WXY-II, fire retardant bag, fire bulkhead, cable refractory coating; there are some new materials used in large-scale projects: fireproofing coating board system (fireproofing coating board, intumescent fireproof sealing tape, elastic fireproof sealant, Waterborne Fire-retardant Coating), fire retardant module system (fire retardant module, sealing gum, cable refractory coating), fireproofing plaster system (fireproofing plaster, sealing gum, cable refractory coating).
Q:What's the A grade fireproofing material?
A grade fireproofing material: 1. fire-proof plate; 2. fireproof wooden door; 3. fireproof wooden window frame; 4. fire resisting shutter; 5. fireproof and mothproof wood; 6. fireproof glove compartment; 8. fire retardant coating; 9. fire-proof sealing material.
Q:What are the characteristics of phenolic resin as a refractory material?
Q:What's the refractory material?
Main components of basic refractory are magnesium oxide and calcium oxide, and magnesia brick is commonly used. For the magnesia brick with magnesium oxide content of more than 80%-85%, it has good resistance to basic slag and scum, and it has higher refractoriness than that of the clay brick and silica brick. It is mainly applied to the open hearth furnace, oxygen-blown converter, electric furnace, non-ferrous metal smelting equipment and some high-temperature devices.
Q:Is the linear change on reheating the same as heating permanent linear change of refractory material?
“+”represents expansion. the afterexpansion and aftercontraction after cooled to be at room temperature. The change may significantly damage the masonry of thermal kiln. There are regulations on the linear change on reheating of common refractory material in the national standard. Some physical chemical changes may continue. It is defined as the change from being heated to the specified temperature of refractory material sample. Heat preserving for a while till afte cooling to be at room temperature, then the residual will expand or contract in its length, heat preservation for a while, organization vitrification, the irreversible changes of its length refers to heating the firing refractory to be at high temperature, so as to make the volume of refractory materials expand or contract, due to the influence of uneven temperature or lack of time, otherwise it will cause the deformation of the refractory ball and make this indicator within standard even reach smaller value, so firing control must be strengthened in product production. But it is should not be too high. For refractory materials with same chemical composition, the linear change on reheating is produced in the heating process. Properly increasing sintering temperature and prolonging the holding time is an effective process measures, make its firing inadequate. When subjected to high temperature, it can reduce the thermal shock resistance. Minus sign "-" represents contraction. The permanent line rate refers to heating the fire refractory ball to the specified temperature. Linear change on reheating, also known as residual linear change, is an important indicator to assess the quality of refractory in the long time use. To control the permanent line rate within the standard or reach the minimum value.
Q:what is best for making refractory insulation for Blast furnace, hot stove.
high alumina insulating brick diatomite brick
Q:What kind of refractories do the anode baking furnace use?
5% volume density. 2 , The application results show that it has the energy-saving effect. 4, Withstand voltage strength. The 50MPa prebaked anode baking furnace furnace wall replaces traditional small special-shaped brick with steel fibre reinforced castable precast block: The aluminum content is 45-60%. The iron content is less than 1. I know someone uses andalusite bricks. This method, under the condition of not changing the roasting technique , has excellent resistance to CO. If there are investors, you can complete the overhaul and reconstruction work of anode baking furnace, which is still a precedent in the country. The andalusite bricks are significantly better than clay bricks. The volume density of 5% of it is 2.25. The compressive strength of 40MPa aluminum content is 60%, and the iron content is less than 1. The andalusite is more denser in the structure. Physical and chemical indicators are as following: it has a good anti-corrosive of exhaust gas Na2O. This is because its chemical composition and mineral composition are very suitable for anode baking furnace, which has long life and easy construction and other characteristics.
Q:What are the requirements of the performances of brasque refractory?
Physical properties of refractories include structural property, thermal property, mechanical property, usability and operation property. Structural properties of refractories include porosity, bulk density, water absorption, air permeability, pore size distribution,etc.. Refractory thermal properties include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity, thermal emissivity. Mechanical properties of refractories include compression strength, tensile strength, breaking strength, torsional strength, shear strength, impact strength, abrasion resistance, creep property, bonding strength, elasticity modulus. usabilities of refractories include refractoriness, refractoriness under load, reheating linear change, thermal shock resistance, slag resistance, acid resistance, alkali resistance, water resistance, corrosion resistance to CO, conductivity, oxidation resistance, etc.. Operation properties of refractory include consistence, slump, fluidity, plasticity, cohesiveness, resilience, coagulability and hardenability,etc. I hope you can solve the problem with my answer.
Q:Who knows the external wall thermal insulation materials fire rating requirements?
1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, 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: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. I feel the best insulation materials should be modified phenolic board, which can keep insulation and fireproofing, but the unit price is very expensive. Insulation materials in the domestic market have some disadvantages, it is better to considere the materials within the acceptable range in the building needs.
