Performance Characteristics of Siliceous Refractories

Silica Ramming Mass

 

Siliceous refractories are refractory products with a silica content of not less than 93%. Its performance is characterized by high softening temperature of the load (ordinary silicon brick minimum 1620 ℃), good thermal conductivity, acid slag and Fe0, Ca0 and other oxides of erosion resistance.

Coke oven silicon brick: the main stone-like quartz phase, masonry coke oven products. Modern coke oven has thousands of brick type, tens of thousands of tons of refractory material, silica brick is masonry material, accounting for about 60% to 70% of the total amount of refractory bricks. In order to improve the thermal conductivity of coke oven silicon brick, the study found that: in the ingredients by adding 1% -2% of the metal oxides, such as copper oxide, iron oxide, titanium oxide, can increase the thermal conductivity of about 10%.

It has also been studied by adding Sr, SiC, Si3 N4, to produce SiO2 during firing, and to reduce the porosity of the product to improve the thermal conductivity.

General scales of quartz for 50% -75%, high-grade products due to less flux impurities, more than 50% square quartz, residual quartz is not greater than 3%.

Hot stove with silica bricks: high temperature for the blast furnace hot stove parts, to squash quartz crystal phase of the silicon products, the physical and chemical indicators. Fused silica products: in the silicon refractory, in addition to silica bricks, there are quartz Product, which is made of pure pure quartz stone. With fused silica as raw materials, raw clay or organic matter as a binder, the use of semi-dry or casting molding products, and 1100 ~ 1350 ℃ in the firing, insulation O. 5 ~ lh. 800 ℃ above to quickly heat up, try to avoid the crystallization of quartz glass.
