The cushion block is characterized by comprising an assembly I, an assembly II and an assembly III, wherein an inner cambered surface corresponding to outer diameters of round blanks and tube blanks is arranged on the upper surface of the assembly I, and an assembly matching hole provided with a blind bottom is formed in the bottom of the inner cambered surface; the top of the assembly II is a plane, an outer cambered surface corresponding to the inner cambered surface on the assembly I is arranged at the bottom of the assembly II, and a pin matched with the assembly matching hole in the assembly I is arranged at the bottom of the outer cambered surface; the assembly III is a cylindrical object, and the outer diameter of the assembly III is in clearance fit with the assembly matching hole in the assembly I; the assembly I and the assembly II are combined to be used for square blanks and plate blanks, and the assembly I and the assembly III are combined to be used for the round blanks and the tube blanks. Compared with the prior art, the cushion block has the benefit as follows: the cushion block is capable of meeting production requirements for various blank heating in a hot rolling process, so that a same walking beam type heating furnace can heat the square blanks, the round blanks, the tube blanks or the plate blanks simultaneously.
Description
Technical field
The utility model relates to the walking beam heating furnace field in ferrous metallurgy production, relates in particular to the built-up type stove beam pad block of a kind of square billet, circle base, pipe, slab use.
Background technology
At present, the requirement that domestic hot rolling technology production line is produced in order to meet many bases kinds such as square billet, circle base, pipe, slab, need in processing line, build the production of multiple process furnace for different shape blank, the ring furnace of even another independent supporting heating circle base and the reheating furnace of heating pipe.For walking beam furnace, its essential distinction is mainly different size and the form that adapts to the stove beam pad block of square billet, slab and adaptation circle base, pipe, the multiple process furnace of hot rolling technology can take larger process layout space, the raising and the investment that affect overall efficiency are larger, can cause in a sense the waste of resource.
Summary of the invention
The purpose of this utility model is to provide a kind of built-up type stove beam pad block, can be for square billet, circle base, pipe, slab and, the production requirement that meets same seat process furnace and heat many bases kinds such as square billet, circle base, pipe, slab simultaneously.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of built-up type stove beam pad block, comprises assembly one, assembly two and assembly three, and the upper surface of assembly one is provided with the intrados corresponding with the external diameter of circle base, pipe, and the bottom of intrados is provided with the assembling mating holes with the blind end; The top of described assembly two is plane, and bottom is provided with the extrados corresponding with intrados on assembly one, the bottom of extrados be provided with assembly one on the pin that matches of assembling mating holes; Described assembly three is pillars, and the assembling mating holes of the external diameter of assembly three and assembly one is running fit; Wherein after assembly one and assembly two combinations for square billet and slab, when assembly one combines with assembly three for circle base and pipe.
Short 1～the 3mm of the degree of depth of the Length Ratio assembling mating holes of the pin on described assembly two.
Short 1～the 3mm of the degree of depth of the aspect ratio assembling mating holes of described assembly three.
The end face of described assembly three is provided with the inclined hole of easy disassembly operation.
Compared with prior art, the utility model beneficial effect is:
Be applicable to the production requirement of many kinds blank heating in hot rolling technology, make same seat walking beam heating furnace both can heat square billet, slab, there is again the function of heating circle base, pipe.This cushion block can adapt to the transformation that reuses, and also can adapt to new project, realizes multi-use; Especially integrated artistic production line, there is the arrangement space of dwindling, reduce the advantage such as invest, enhance productivity, by the effect of the air-isolation layer between cushion block and steel billet, weaken the direct cooling effect of walking beam stove beam pad block to steel billet simultaneously, reduced the generation of heating " black seal ".

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Seeing Fig. 1 to Fig. 3, is respectively the utility model assembly one, assembly two, assembly three example structure schematic diagram, and the upper surface of assembly 1 is provided with the intrados 4 corresponding with the external diameter of circle base, pipe, and the bottom of intrados 4 is provided with the assembling mating holes 5 with the blind end; Assembly 1 is provided with the hole or the trimming that reduce this body weight.
The top of assembly 22 is plane, and bottom is provided with the extrados 6 corresponding with intrados 4 on assembly 1, the bottom of extrados 6 be provided with assembly 1 on the pin 7 that matches of assembling mating holes 5; Extrados 6 is integrated design with pin 7.Pin 7, as anchor connection, can be realized the globality after cushion block combination.
Assembly 33 is pillars, and the assembling mating holes 5 of the external diameter of assembly 33 and assembly 1 is running fit; The top of assembly 33 is provided with inclined hole 8, so that dismounting operation.
On same seat walking beam heating furnace, can realize by the replacing combination of the each assembly of the utility model the object of square billet, circle base, pipe, slab use, replacing, easy to assembly, can adapt to the production of different blank kinds well.
See Fig. 4, it is the utility model combination embodiment mono-schematic diagram, after assembly 1 and assembly 22 combinations for square billet and slab, short 1～the 3mm of the degree of depth of the Length Ratio assembling mating holes 5 of the pin 7 on assembly 22, assembly 1 is sustained height with the rear upper surface of assembly 22 combination combination, due to the reason such as mismachining tolerance and precision, between the extrados between assembly 22 and assembly 1 and intrados, can have gap by nature, form an air-isolation layer, can effectively reduce billet black print " generation.
See Fig. 5, the utility model combination embodiment bis-schematic diagram, assembly 1 is used for circle base and pipe while combination with assembly 33, short 1～the 3mm of the degree of depth of the aspect ratio assembling mating holes 5 of assembly 33, after combination, due to the reason such as mismachining tolerance and precision, between assembly 1 and blank, can there is gap by nature, form an air-isolation layer, can effectively reduce the generation of the black seal of steel billet.Assembly 33 also can prevent that iron scale is deposited in assembling mating holes 5.
