Embodiment Construction

[0028] The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. Such as figure 1 As shown: there is a carbon ceramic heating base 1, and electrode lead rods 2 are connected to both ends of the carbon ceramic heating base 1. The carbon ceramic heating base 1 is covered with a protective tube 3, and the space between the carbon ceramic heating base 1 and the protective tube 3 is filled. There are insulating and heat-conducting powder4.

[0029] The specific processing method is:

[0030] a. Mix carbon powder, non-oxide ceramic powder, alloy oxide, and infrared radiation powder in a volume ratio of 5-8:0.5-1.5:0.5-1.5:0.5-1.5, stir evenly, and process it into carbon ceramics by chemical curing The two ends of the heating substrate 1 should be fixed with the electrode lead-out rod 2 . The particle size of carbon powder, non-oxide ceramic powder, alloy oxide and infrared radiation powder should be less than ...

Abstract

This invention discloses a ceramic-carbon heating pipe having a heating matrix, an electrode lead-out rod is connected with both ends of matrix sleeved with a protection pipe, insulation and heat conduction powder is filled between matrix and protection pipe. Its electric-heat transformation rate reaches as high as 99.6% and is oxidation resistant, not easy to be broken with a long work life to 50000 hours, 1.5 times higher than that of the national standard.

Description

Technical field: [0001] The invention relates to an infrared electric heating element, in particular to a carbon ceramic heating tube. Background technique: [0002] At present, there are many types of electric heating elements for electric heating equipment on the market, but they can be roughly divided into three categories, which are introduced as follows: [0003] 1. Alloy heating element [0004] Alloy heating wires are made of high-resistance alloy materials, generally iron-chromium-aluminum or nickel-chromium alloys are used to make resistance wires, on this basis, various heating elements are made after secondary processing. This alloy resistance wire tends to become brittle after being cooled by high temperature use, and the longer the use time, the more serious the brittleness after cooling, poor shock resistance, short service life, and low electric-to-heat conversion efficiency. In addition, crystalline magnesia is often used as the insulating filling material ...
