Abstract
The present invention relates to an abration-resistant corudum ceramic material, and its raw material formula contains calcined Al2O3 fine powder 92-95%, MgO 0.5-1%, CaO 0.5-2.5%, Cr2o3 0.5-1.5%, TiO2 0.5-1.5%, oxide of rare metal 1-1.5%, ZrO2 1-1.5%, SiO2 0.5-1.5% and additional high-temp, adhesive 3-6%. Said invention is extensive in raw material source, high in hardness, large in density and good in abrasion-resistance, toughness and resistance to impact.
Description
The present invention relates to a kind of prescription of corundum ceramic.
Corundum ceramic is because a series of good physicalies such as hardness height, high temperature resistant, wear-resistant, erosion resistant, be applied to the industrial system from the seventies in the advanced country abroad, as industrial system serious wear positions such as fuel-burning power plant, smelting iron and steel factory, mine transportations.But because corundum ceramic toughness is relatively poor, anti-impact force is weak etc., thereby external corundum ceramic is restricted in Application Areas.In order to solve or avoid the problems referred to above, external advanced country generally adopts high-grade material more to improve the wear resistance of product and toughness etc., as the SALON pottery, but, therefore also limited the widespread use in the wear-resisting system of industry of this series products because these ceramic costs are very high.
From the seventies, many universities and colleges of China and institute all begin to carry out the research of corundum ceramic.But because of grasping some gordian techniquies wherein at that time, as it is undesirable etc. to fill a prescription, and adds that research equipment does not match, as do not have the high temperature kiln about 1700 degree Celsius that therefore, product fails to reach a standard always.The early 1990s, domestic research and the production of having carried out corundum ceramic about scientific research institutions, simple 95 porcelain (95% aluminium content) are though there is certain degree of hardness but these corundum ceramics are, but wear resisting property, shock resistance are relatively poor, therefore the corundum ceramic product is used to make valve chip etc. more, fails to have breakthrough for the problem of materials at the serious position of wearing and tearing in the industries such as electric power, metallurgy, mine, light industry, chemical industry always.Therefore, high-abrasive material particularly the research of abrasion-resistant corundum ceramics just become one of difficult problem that domestic and international scientific research personnel captures with using.
Purpose of the present invention aims to provide a kind of have stronger wear resistance and shock resistance and good toughness, the abrasion-resistant corundum ceramics that hardness is high.
The objective of the invention is to realize by following manner:
Prescription of the present invention is: (by weight percentage)

High-temperature agglomerant can be carboxymethyl cellulose, water glass etc.
Production process of the present invention is:
Enter factory by behind the ingredient inspection with the powdered raw material is packed, with the proportioning weighing and burden of raw material, by ball mill ball milling powdering, drying by foregoing invention.Granulate by screening, to reach best tap density.It is old to enter feed bin then, makes moisture more even, improves processability.Afterwards, can be pressed into different shape, the work in-process after the compacting are put into saggar so that burn till product according to the design requirements machine.Reinstall in the specific high temperature kiln, under the temperature about 1700 ℃, burn till about 13 hours and (contain soaking time).Finished product after burning till is taken out the kiln cooling.Product after burning till can be pieced into the definite shape size together on request so that installation and transportation.Check at last, pack, put in storage.
The technological process of production of the present invention is expressed as follows by arrow:
Old → moulding → dress alms bowl → loading of kiln that raw material powdery → packed advances the factory → check → weighing and burden → ball milling → drying → feed bin of granulating → go into → burn till → kiln discharge → piece together → check → pack → put in storage.
The present invention has overcome the deficiency that domestic and international corundum ceramic had; Has simultaneously the advantage of corundum ceramic self again.Have the hardness height, wear resisting property is good, good toughness, and anti-impact force is characteristics preferably.Raw material of the present invention Al as described
