Technical field
The present invention relates to the main accessory of a kind of belt and tubular type conveyor apparatus: the application of a kind of plasticizing high-aluminum ceramic support roller (tempering carrying roller).
Background technology
Belt and tubular type belt conveyor apparatus, be the equipment that indispensable transportation such as domestic and international electric power mining, chemical industry, coal, coking, salt industry, metallurgy, iron and steel, non-ferrous metal, Aluminum, harbour, ore dressing, cement is carried, pass through over the years with the main accessory of metal iron and steel carrying roller as this equipment, because metal carrying roller, processing difficulties, than great, cost an arm and a leg, production cost height, wearing and tearing be big, not corrosion-resistant, power consumption is very big, by it product that much is confined to irony is arranged, can't satisfy the requirement of quality product.
Summary of the invention
Purpose of the present invention is to provide the plasticizing high-aluminum ceramic support roller that a kind of performance high-quality is reliable, reach 3 to 5 times of general Ceramic idlers duration of service.
A kind of plasticizing high-aluminum ceramic support roller, i.e. tempering Ceramic idler, the component of this Ceramic idler comprises mullite, calcination aluminum oxide powder, zircon, zirconium white and clay, and rare earth oxide, binding agent, lubricant; The weight percent of component is: mullite 40%, calcination aluminium powder 25%, zirconium white 10%, zircon 12%, clay 15%, surplus percentage ratio are other conventional chemical thing binding agent and lubricant.The chemical component weight per-cent of component is: SiO 225-38%, Al 2O 360-63%, ZYO 25-15%, Fe 2O 30.5-0.8%, other residue percentage composition is CaO, MgO, Y 2O 3Adopt dry powder, hydrostatic profile technology, form through 1480-1500 ℃ of high-temperature roasting.
The optimum chemical composition of described Ceramic idler is formed, and is SiO by weight percentage 227%, Al 2O 362%, ZYO 210%, Fe 2O 30.7%, binding agent 11%, lubricant 16%, other composition CaO, MgO, Y 2O 3The surplus of occupying weight percent.
Its technology is the dry powder of taking each composition, and high-strength hydrostatic profile forms through 1480-1500 ℃ of high-temperature roasting; Operational path is: raw material → batching → ball milling → deironing, sieve → spray drying granulation → old → isostatic pressing → pick, the finish turning of finishing → with one heart → burn till → check → assemble → check again → pack → dispatch from the factory.
After tested, the mechanical property of tempering Ceramic idler of the present invention is as follows:
Resistance to compression>300MPa, anti-folding>140Mpa, acid fastness 99.8%, fastness to alkali: 97%
Hardness>8.5 grade (Mohs), use temperature :-20 ℃~60 ℃, water-intake rate<0.1%, density>3.0, wear rate<0.00026, fracture toughness property: 6.3MPa*m 1/2
Plasticizing high-aluminum ceramic support roller of the present invention (tempering Ceramic idler) is the new ceramic material of advanced new and high technology of 21 century, through meticulous combination formula, the main raw material that it adopts has: combination formulas such as mullite, aluminum oxide powder, zircon, clay, zirconium white, talcum, binding agent, lubricant form main chemical: SiO 225~28%, Al 2O 360~63%, ZrO 25~10%, Fe 2O 30.5~0.8%, MgO 0.24~0.8%, other chemical element trace can not influence quality product.Ultimate compression strength is 3860kg/cm2, wear-resisting rate 0.00026,8.5~9 grades of hardness.In process of production, adopted state-of-the-art dry powder isostatic pressing process, the molecular density height, the yield rate height, intensity is big, and wear rate is little.Do not have the limitation influence of specification aborning, be more than 3 to 5 times of general Ceramic idler duration of service, and the performance high-quality is reliable.Plasticizing high-aluminum ceramic support roller of the present invention (tempering Ceramic idler) is a comprehensive aluminum oxide in the ceramic industry, the Zirconium oxide plasticizing novel material.
Beneficial effect of the present invention:
1. giving full play to that stupalith is wear-resisting, corrosion-resistant, on the basis of advantage such as high temperature oxidation resisting, light specific gravity, ultimate compression strength are high, passing through ZrO 2Transformation toughening, it is big to overcome stupalith fragility, and not impact-resistant birth defects make ceramic material that the good comprehensive performance be arranged, and make carrying roller thereby adapt to.
2. in product design, on the basis of original metal carrying roller, reduce carrying roller proportion, reduce power consumption; Change the carrying roller moulding, ensure the belt belt easy to wear limit phenomenon of steadily, not derailing; Improve the carrying roller fastness to rubbing, increase work-ing life; Increase ceramics strength, ensure that structure is agile.
3. dependence be can significantly reduce with ceramic substituted metal, resource consumption and pollution (raw material sources of Production of Ceramics are very extensive, energy consumption and pollute more much lower) more can be reduced than Iron and Steel Production to external iron ore; Toughening ceramic overcome conventional ceramic fragility greatly, not impact-resistant congenital shortcoming, work-ing life and effect are much better than conventional ceramic.Cost that it is cheap and higher use value make the toughening ceramic carrying roller that very strong competitive power and vitality be arranged.
4. adopt isostatic pressing process and equipment to be shaped, can make ceramic product that higher compactness is arranged, dimensional precision promotes wear-resisting, corrosion-resistant and shock resistance (toughness), and physical strength, especially can eliminate or reduce the wet-formed latent defect that produces because of structure is inhomogeneous.
Superior characteristic such as the present invention for steel, has given full play to that the stupalith wear resisting property is good with porcelain, corrosion resistant performance is strong, high temperature oxidation resisting, light specific gravity, ultimate compression strength are big.Be the frangible performance of solution pottery simultaneously, the one, utilize the high aluminum-containing mullite of Zirconium oxide plasticizing to have the mechanism of the wild phase and the high high-temp stability of special crystalline structure, and adopted the inline process of most advanced high-strong dry powder isostatic pressing.Formed a kind of plasticizing high-aluminum ceramic support roller (tempering Ceramic idler) new technologies and materials.
