Abstract
A fire-less zirconium- and chromium-corundum compounded refractory is made up of electrofused white corundum, ore containing Cr2O3, ore containing ZrO2 and complex phosphate as binder through pressing. Its advantages are simple process, no need of high-temp burning, low cost, long service life elongated by 3-5 times and high thermal stability. It can be used in ferrous metal smelting.
Description
The present invention relates to a kind of fire performance and broad-spectrum novel refractory-non-sintered corundum, chromium corundum composite refractory of improving in the fire resisting material field.
At present, corundum products is the high grade refractory that is applied to field of smelting, but because corundum products manufacturing process complexity, the production difficulty is big, need high temperature to burn till, its firing temperature is about 1800 ℃, and thermal shock resistance is poor, has therefore limited its use range and can not bring into play its original performance fully.
The objective of the invention is provides a kind of novel refractory materials non-sintered corundum, chromium corundum composite refractory for field of smelting, this material has overcome above-mentioned shortcoming, its technology is simple, does not need high temperature to water, and has very high normal temperature, middle gentle hot strength and good thermal shock resistance.
Non-sintered corundum of the present invention, chromium corundum composite refractory content Description:
Non-sintered corundum of the present invention, chromium corundum composite refractory is characterized in that it being based on fused white corundum, and mineral, the mineral that contain zirconium dioxide and the chromium phosphate that adds trioxygen-containingization two chromium is that the wedding agent compacting forms; Its chemical constitution (by weight) is: fused white corundum 78-97%, chromium sesquioxide 5-12%, zirconium dioxide 5-12% are wedding agent with chromium phosphate 4-6%.
The fire performances such as physical and chemical index of non-sintered corundum of the present invention, chromium corundum composite refractory are improved largely than corundum products, and can improve 3-5 doubly than corundum products work-ing life, and manufacturing process is simple, does not need high temperature to burn till.Have very high normal temperature, middle temperature, hot strength and good thermal shock resistance, can use the non-sintered corundum, the chromium corundum composite refractory is manufactured: refractory products such as square brick, nozzle brick, slide brick, lining brick, also can be mixed with loose refractory and use, be widely used in ferrous metal smelting.The present invention also has save energy, reduces cost, shortens the characteristics of production cycle.
Embodiment 1:
Make 1000Kg non-sintered corundum, chromium corundum composite refractory, white fused alumina 700Kg is melted in power taking, and its granularity is greater than 1mm, less than 5mm; White alundum powder 180Kg is melted in power taking, and its granularity is less than 0.074mm; Get baddeleyite powder 50Kg, its granularity is less than 0.043mm; Get chromium sesquioxide powder 70Kg, its granularity is less than 0.005mm; Add chromium phosphate 55kg, mix the back pressure forming,, be finished product through 100 ℃ of dryings 5 hours.The non-sintered corundum of above proportioning, chromium corundum refractory materials are applicable to making slide plate, the mouth of a river, lining brick etc.
