Abstract
The utility model relates to a high temperature wear resistance thermocouple protective tube, of which the outer layer is high temperature and wear resistant complex metal protective layer cast on an inner alloy tube of the inner layer. The high temperature and wear resistant complex metal layer of the utility model comprises a plurality of elements. Wherein, C is more than or equal to 1.0, Si is more than or equal to 3.0, Mn is more than or equal to 2.0, Cr is more than or equal to 38.0, Mo is more than or equal to 5.0, Ti is more than or equal to 1.0, Ni is more than or equal to 8.0, W is more than or equal to 5.0, and Re is more than or equal to 7.0. The precise casting is adopted by the utility model to form high temperature and wear resistances and better temperature sensitivity. The response time is 5-6 seconds. With double layers structure and special high temperature and wear resistant complex metal layer, the utility model can satisfy technical index requirements of wear resistance and high temperature resistance. The operational economic loss caused by electric thermocouple losses is solved during the application of a circulating fluidized bed boiler. The service life of the thermocouple is improved and the service life is eight to twelve months under normal working conditions. The utility model prolongs the service life the boiler as a whole and at the same time reduces the maintenance time of the boiler.
Description
Affiliated field: the utility model relates to a kind of high-temperature wearable protecting tube.
Background technology: the thermopair overwhelming majority all is applied to circulating fluidized bed boiler; therefore wear-resisting and resistant to elevated temperatures technical indicator is had higher requirements; existing protecting tube adopts stainless-steel tube; it is a single tube structure; wearing quality is relatively poor, and the while is non-refractory also, and serviceable life is about 1 month; need in time to change, prolonged servicing time simultaneously service time that has reduced boiler on the whole.
Summary of the invention: the purpose of this utility model provides a kind of long service life, the high-temperature wearable protecting tube of good heat conduction effect.The purpose of this utility model realizes by following structure: the utility model is a kind of high-temperature wearable protecting tube; the body skin is a heat resistant and wear resistant composite metal protective seam, and the casting of heat resistant and wear resistant composite metal protective seam is compounded on the alloy pipe of internal layer.Heat resistant and wear resistant complex metal layer of the present utility model is made of multiple element, wherein C 〉=1.0, Si 〉=3.0, Mn 〉=2.0, Cl 〉=38.0, Mo 〉=5.0, Ti 〉=1.0, Ni 〉=8.0, W 〉=5.0, Re 〉=7.0.The utility model adopts accurate casting, form not only heat resistant and wear resistant but also have temperature sensitivity preferably, the response time is 5-6 second, and the utility model is owing to have double-decker, and have special heat resistant and wear resistant complex metal layer, therefore can satisfy wear-resisting and resistant to elevated temperatures technical requirement.In the application of circulating fluidized bed boiler, solved the maneuverability economy loss that produces because of the electroheat pair loss, in the serviceable life of having improved electroheat pair, nominal situation following serviceable life was at 8-12 month.The utility model stainless steel prolongs pipe, can save material, reduces machining precision.The utility model has prolonged the service time of boiler on the whole, has reduced the servicing time of boiler simultaneously.
