Wear-resistant ceramic tube performance in similar products

Wear-resistant ceramic tube abrasion resistant lining used in power plants, cement plants is very big, the enterprise in the process of production, consumption of wear and tear is very strong, the traditional products because of can't afford such a high intensity of wear and tear, gradually fade out people's field of vision, instead, the wear-resisting ceramic tube.

 Wear-resistant ceramic tube abrasion resistant lining ceramic layer at room temperature under compressive stress, the steel layer under tensile stress.Only temperature to 400 ℃ above, due to the different thermal expansion coefficient, thermal expansion of the new stress field to cancel each other out of the existence of the original stress field in the ceramic tube, the balance of ceramic layer and steel both in the stress state.When the temperature to 900 ℃, the ceramic tube in cold water, repeatedly, the ceramic layer does not crack or split, show the ordinary ceramic incomparable thermal shock resistance, this performance is useful in the engineering construction.Because the outer layer is steel and the inner temperature is not split, in the construction, the flange, purging, explosion-proof door mouth to welding, direct welding method can also be used for pipe connection, than the wear-resistant alloy cast iron pipe, cast stone and gangsu, rubber tube in the construction of steel welding or not.Ceramic tube mechanical shock resistance, in transportation, installation, knock and gravity bending deformation between the two stents, corundum layer are not broken off.

At present, the production of ceramic tube wear-resisting layer abrasion resistant lining is dense alpha model 3 oxidation 2 aluminium, acid degree of 96-98%. The 3 oxidation 2 aluminium neutral oxide, with acid, alkali, salt, no chemical reaction.3 oxidation 2 aluminium are inorganic substances, on the wear resistance and corrosion resistance is much higher than ordinary steel tube, through the actual test, wear-resisting stainless steel high more than ten times higher than that of the performance of the ceramic tube, can say in steel pipe products.
