Technical field
It the utility model is related to steel works equipment technical field, and in particular to a kind of conveying roller, more particularly to one kind are used for steel
Conveying roller in factory in roller hearth type heating furnace.
Background technology
Roller hearth type heating furnace is the very important heat steel equipment of steel mill, and its main function is to transport and heat material
Material, needing to install a conveying roller additional at a certain distance along roller bottom stove whole furnace superintendent, steel billet is conveyed on conveying roller,
It can arrange that burner heats to steel billet in the burner hearth of roller hearth type heating furnace.
Normal conditions lower roller has two kinds of annular roller and plain-barreled roll, and annular roller is only used for the conveying of sheet material, and plain-barreled roll can use
In the conveying of sheet material, tubing, shaped steel and bar.The roller set of conveying roller outer layer is typically made of heat resisting steel, and some also uses carborundum
Material makes.Conveying the conveying roller of heat treatment material at high temperature must ceaselessly rotate, and when stove is empty to be burnt or do not discharge, be
Prevent from conveying bending, also want reduction of speed to rotate or swing with the rotating speed of 0.5-1.5 weeks per minute.Conveying roller will be taken the photograph in temperature 1000
More than family name's degree thermic load and the lower rotation of steel billet load effect, while again by mechanical injuries (collision, the mill of heated steel billet
Damage etc.), therefore, the material requirements of conveying roller has higher temperature strength and antioxygenic property.Because the body of roll uses heat-resisting alloy
Material manufacture, cost is very high, and the conveying roller quantity required for a stove is a lot, therefore the use of conveying roller is very important.
Traditional conveying roller is all to pour to build up the cylinder of empty stomach by centrifugation using high nichrome steel, then to the body of roll and
The spindle nose of hearth roll is machined.Now in order to adapt to higher heating-up temperature, by installing water cooling inside conveying roller
The method of pipe, there is water cooled rolls, water cooled rolls is to lead to cooling liquid in the inside of hearth roll, and cooling liquid inside hearth roll with entering
Row heat convection.But the conveying roller of this structure causes body surface temperature because cooling water directly contacts with body of roll inwall
Very low, the heat loss during heating steel billet is very big, and the thermal efficiency is low, causes more serious energy waste, and reduces and added
The heating quality of heated work pieces.
Utility model content
The utility model is in order to overcome deficiency of the prior art, there is provided a kind of steel mill's conveying roller so that in the body of roll
Wall is not directly contacted with water-cooling shaft, had so not only been reduced heat-energy losses but also had been reduced the black print of cooling；Simultaneously by being provided with disk
Spacing body, it is possible to increase the mechanical performance of water-cooling shaft, prevent axle body to be broken；By being provided with thermal insulation layer, heat proof material can be reduced
Internal-external temperature difference.
The utility model is to be achieved through the following technical solutions：
A kind of steel mill's conveying roller, including the water cooling axis body with spindle nose A and spindle nose B, outside the water-cooling shaft body
Roller, the inside of the water cooling axis body is machined with cooling duct along its direction of axis line, and cooling duct is from the spindle nose A ends of one end
The spindle nose B ends of the other end are extended at face；The outside of the water cooling axis body along its length uniform welding have it is multiple
Size identical disk spacing body, and thermal insulation layer is coated with the outer surface of the water cooling axis body, the thermal insulation layer outer wall with
Heat proof material is filled between the inwall of roller, and space is left between heat proof material and the inwall of roller.
Preferably, the both ends of the roller have arc-shaped transition section.
Preferably, it is coated with refractory coating in the outside wall surface of the roller.
Preferably, the heat proof material is pyroceram cotton or broken refractory brick blocks or heat resistance concrete.
Preferably, the thermal insulation layer is rock wool or mineral wool.
Compared with prior art, the beneficial effects of the utility model are：
1st, the outer wall of water cooling axis body and the inwall of roller are not directly contacted with, and are so both reduced heat-energy losses, are reduced again
Cool down black print.
2nd, by being evenly arranged with multiple disk spacing bodies in the outside of water cooling axis body, and disk spacing body is welded to water-cooling shaft
Outside body, the mechanical performance of water cooling axis body on the one hand can be improved, prevents axis body to be broken, on the other hand can play the work of load-bearing
With.
3rd, by that filled with heat proof material, heat-insulated effect can be played, by being provided with thermal insulation layer, can be reduced heat-resisting
The internal-external temperature difference of material.
4th, one end water inlet of water cooling axis body, other end water outlet is simple in construction, effect is also relatively good, and pump is by the cooling of output
Water is transported in water cooling axis body by swivel joint, then is discharged by the swivel joint of opposite side, returns to pump box.
