The electric heating pipe with high mechanical strength has the advantages of small volume, high heating power and high mechanical strength.
Description
Technical field
The present invention relates to the electrothermal tube that a kind of mechanical strength is high.
Background technology
Electrothermal tube has another name called heat-generating pipe, heating tube, formal name used at school tubular electric heating element, it is the heating wire (resistance wire) putting into spiral shape in metal tube, and around it and gap insert the insulating powder (MgO) of good heat resistance, thermal conductivity and insulating properties, heating wire both ends have eduction rod or lead-out wire picks out.It is simple that it has structure, the features such as mechanical strength is high, the heat efficiency is high, safe and reliable, simple installation, long service life.Be widely used in the devices such as various nitre groove, tank, oil groove, acid-base groove, fusible metal melting furnace, air-heating furnace, drying oven, drying box, hot-die.
Electrothermal tube is special is the electric elements of heat energy by electric energy conversion, due to its low price, easy to use, easy for installation, pollution-free, is widely used in various heating occasion.
Tubular metal electrothermal tube typical structure (the most popular structure) is generally made up of 5 parts: insulator, joint filling material, eduction rod, inserts, heating wire, metallic sheath pipe, terminals.
Spiral heating wire helps with extraction the central authorities being positioned at metallic sheath pipe, its manufacturing process penetrates in seamless steel pipe, copper pipe or aluminum pipe by spiral type heating wire, its gap location is filled equably by multitube filling machine and is not only insulated but also the oxide isolation of heat conduction, as crystal magnesium oxide powder (also available alumina or clean quartz sand etc.).Then with machine for shrinking by caliber shrinking, making medium of oxides closely knit (density reaches more than 3.3g/cm3), ensure heating wire and air exclusion, there is not skew and brushes up against tube wall in center.Like this.Unit are caloric value just can increase by tens times.Useful life also can be increased to more than 10 years accordingly.Compared with the electric heating element of identical large heat, tubulose electrothermal tube can save the thermo electric material of 5%, and the heat efficiency can reach more than 90%.
Therefore, from the structure of electrothermal tube, tubular metal electrothermal tube uses the most at present, and structure is simple, and dependable performance, the Encapsulated electric thermal element of long service life, can be used successfully on industry, household electrical appliance, uses more and more extensive.Wish that the structural principle of more user to electrothermal tube has had clearly to understand.

The electrothermal tube that a kind of mechanical strength of the present invention is high, has that volume is little, heating power and a high advantage of mechanical strength.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Wherein, the electrothermal tube that described mechanical strength is high comprises the steel alloy of the superiors, thermoset plastics and the undermost carborundum in intermediate layer combine, described steel alloy comprises iron-carbon alloy, aluminium, copper and mickel, described thermoset plastics is phenolic plastics, described carborundum comprises quartz sand, petroleum coke and Mo Sangshi, described steel alloy accounts for the 71%-75% of the overall component of the high electrothermal tube of mechanical strength, described phenolic plastics account for the 5%-6% of the overall component of the high electrothermal tube of mechanical strength, described carborundum accounts for the 18%-26% of the overall component of the high electrothermal tube of mechanical strength, described phenolic plastics comprise phenolic resins and amino fibre.
Further illustrate, described steel alloy accounts for 73% of the overall component of the high electrothermal tube of mechanical strength, and described phenolic plastics account for 5% of the overall component of the high electrothermal tube of mechanical strength, and described carborundum accounts for 22% of the overall component of the high electrothermal tube of mechanical strength.
Further illustrating, steel alloy kind is a lot, usually how much is divided into low-alloy steel (content <5%) by alloying element content, medium alloy steel (content 5% ~ 10%), high-alloy steel (content >10%); Superior alloy steel, speciality steel alloy is divided into by quality; Structural alloy steel, stainless steel, acid resisting steel, abrasion-resistant stee, heat resisting steel, alloy tool steel, roller bearing steel, alloy spring steel and property steel (as magnetically soft steel, permanent-magnet steel, nonmagnetic steel) etc. are divided into again by characteristic and purposes.In steel except iron content, carbon and a small amount of inevitably silicon, manganese, phosphorus, element sulphur, also containing a certain amount of alloying element, alloying element in steel has silicon, manganese, molybdenum, nickel, presses against, wherein one or more such as alum, titanium, niobium, boron, lead, rare earth, and this steel is steel alloy.
