Abstract
The utility model belongs to a repatching die for a dip pipe of a refining furnace used in a steel mill, particularly to a casing patch cylinder for the dip pipe of the refining furnace. A disk which is formed by steel plates and provided with a circumferential wall has a sealed bottom surface and an opened top surface, a cylinder is fixedly connected to the central hole on the bottom surface of the disk, the top end of the cylinder is higher than the circumferential wall of the disk, the radius of the circumferential wall of the disk is 8-12 mm bigger than that of the excircle of the dip pipe, and the excircle radius of the cylinder is 8-12 mm smaller than the inner radius of the dip pipe. The utility model can realize the effect that fast repatching fire-proof materials are filled into the repatching die for hot repatching under the status of high temperature of the dip pipe, and has good repatching quality, high bonding strength, and long service life.
Description
Technical field
The utility model belongs to the repairing mould of the refining furnace dip pipe of steel mill use, and particularly a kind of refining furnace dipping pipe box is mended tube.
Background technology
The lower surface of steel mill RH-KTB refining furnace dip pipe, the invar water erosion is ftractureed in the process of using.Prior repairing method adopts at the injury region gunning refractory of dip pipe lower surface or adopts the manual way of subsidizing refractory material.The weak effect of its repairing can not reach and improve the dip pipe purpose in service life.
The utility model content
The purpose of this utility model is to provide a kind of refining furnace dipping pipe box to mend tube, can be earlier in repairing mould filling repair refractory material fast, under the dip pipe condition of high temperature, carry out hot repair, repairing quality is good, adhesive strength height, long service life.
The purpose of this utility model is to provide a kind of refining furnace dipping pipe box to mend tube, the disk that constitutes by steel plate with circumferential wall, its bottom surface sealing, opened top, affixed cylindrical drum on the centre bore of disk bottom surface, the top of cylindrical drum exceeds the circumferential wall of disk, the big 8-12mm of radius ratio dip pipe exradius of disk circumference wall, and the exradius of cylindrical drum is than the little 8-12mm of inside radius of dip pipe.
When needs are repaired the refining furnace dip pipe, repair refractory material fast in the indoor filling of the annulus of disk, under the dip pipe condition of high temperature, utilize the maintaining car lifting body, carry out the socket hot repair with filling the utility model jacking to the dip pipe position to be repaired of repairing refractory material fast.Under dip pipe high temperature, carry out Rapid Thermal and repair the adhesive strength height of the refractory material of repairing and high temperature dip pipe.Repair section cracking under the dip pipe effectively, by the dip pipe stove in service lifes 50 that original method for repairing and mending is repaired, bring up to 70 stoves the service life of having improved dip pipe, increased stove in service lifes 20.Therefore, the utility model has realized that elder generation's filling in repairing mould repairs refractory material fast, carries out hot repair under the dip pipe condition of high temperature, and repairing quality is good, adhesive strength height, long service life.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is main TV structure figure of the present utility model;
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
The specific embodiment
A kind of refining furnace dipping pipe box is mended tube, as shown in Figure 1 and Figure 2, the disk with circumferential wall 1 that constitutes by steel plate, its bottom surface sealing, opened top, affixed cylindrical drum 2 on the centre bore of disk 1 bottom surface, the top of cylindrical drum 2 exceeds the circumferential wall of disk 1, the big 8-12mm of radius ratio dip pipe exradius of disk 1 circumferential wall, the big 10mm of radius ratio dip pipe exradius of circumferential wall, the exradius of cylindrical drum 2 is than the little 8-12mm of inside radius of dip pipe, and the exradius of cylindrical drum 2 is than the little 10mm of interior radius of circle of dip pipe.The high 100mm of circumferential wall of the aspect ratio disk 1 of cylindrical drum.
