Abstract
A kind of mullite ceramic metal tube composite roll rod, comprise mullite ceramic outer tube, it is characterized in that, in mullite ceramic outer tube, be provided with metal tube, the axial uniform welding of metal tube lateral surface has reinforcement rib, fills netted refractory fibre between mullite ceramic outer tube wall and metal tube.Mullite ceramic metal tube composite roll rod of the present utility model, utilizes intensity and the toughness of inner layer metal pipe on the one hand, enhances the total bearing capacity of composite roll rod; On the other hand, in the use procedure of roller rod, boring part can water flowing or ventilation, by the flowing of current or air-flow, the temperature of quick reduction roller rod, prevent metal tube and mullite ceramic outer tube from causing ceramic outer pipe to ftracture due to expansile difference, the reduction of inner layer metal pipe temperature simultaneously effectively can prevent the high-temperature oxydation of metal tube.
Description
Technical field
The utility model relates to roller way kiln ceramic rod, especially a kind of mullite ceramic metal tube composite roll rod.
Background technology
Ceramic rod refer to fireclay refractory and natural mineral raw through selected, pulverize, be shaped, calcining and other processes and the refractory product made, be one of crucial accessory of roller way kiln, mainly play the effect of transmission and load-bearing.At present, along with roller way kiln is to Wide Band Oxygen Sensors, operation at high temperature future development, requires that ceramic rod elevated temperature strength is high, at high temperature can run continuously, to remain unchanged shape under the load effect of deadweight and goods.The primary raw material producing ceramic rod comprises kaolin, fire clay, fire-resistant corundum aggregate and α-Al
2o
3deng.At present, the ceramic rod of roller way kiln is that main material shaping sintering forms mainly with mullite-corundum, mullite-corundum-baddeleyite greatly.Single-layer tubular structure mostly is after existing ceramic rod thermal sintering, roller rod load capacity is poor, and the raising of order front roller rod intensity generally adopts the method increasing wall thickness, the method can play the effect increasing roller rod intensity to a certain extent, but the increase of wall thickness result in the increase of roller rod own wt, the raw material production cost of roller rod can be increased on the one hand, on the other hand, the conference that adds of wall thickness causes the heat endurance of roller rod to reduce, heat-sinking capability is deteriorated, the heat at high temperature accumulated in club can not distribute in time and produce internal stress, inside and outside contraction when working under causing roller rod hot conditions is inconsistent, roller rod is caused to crack and burst, have a strong impact on production, cause the waste of raw material and the energy and the increase of production cost.
Summary of the invention
The purpose of this utility model be just to provide a kind of high temperature resistant, intensity is high, good toughness, long service life, is applicable to the mullite ceramic metal tube composite roll rod that expanded letter ceramic roller cellar for storing things stove uses.
Mullite ceramic metal tube composite roll rod of the present utility model, comprise mullite ceramic outer tube, it is characterized in that, in mullite ceramic outer tube, be provided with metal tube, the axial uniform welding of metal tube lateral surface has reinforcement rib, fills netted refractory fibre between mullite ceramic outer tube wall and metal tube.
It is 2-20mm that described metal tube strengthens rib heights.
Mullite ceramic metal tube composite roll rod of the present utility model, utilizes intensity and the toughness of inner layer metal pipe on the one hand, enhances the total bearing capacity of composite roll rod; On the other hand, in the use procedure of roller rod, boring part can water flowing or ventilation, by the flowing of current or air-flow, the temperature of quick reduction roller rod, prevent metal tube and mullite ceramic outer tube from causing ceramic outer pipe to ftracture due to expansile difference, the reduction of inner layer metal pipe temperature simultaneously effectively can prevent the high-temperature oxydation of metal tube.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is parts structural representation in Fig. 1.
Detailed description of the invention
A kind of mullite ceramic metal tube composite roll rod, comprise mullite ceramic outer tube 1, it is characterized in that, metal tube 5 is provided with in mullite ceramic outer tube 1, the axial uniform welding of metal tube 5 lateral surface has the reinforcement rib 3 of more than 3 or 3, fills netted refractory fibre 2 between mullite ceramic outer tube 1 inwall and metal tube 5.
It is isometric with metal tube 5 that described metal tube strengthens rib 3, and strengthening rib 3 is highly 2-20mm.
The cavity 4 of energy water flowing or ventilation is had in metal tube 5.
