The utility model is provided with a metallurgical bond connection layer between adjacent surfaces forming a space block head and a space block base of the compound space block to cause the space block head and the space block base to be firmly combined as a metallic and continuous whole structure. Compared with the prior art, the utility model has the advantages that the integral rigidity is good, the mechanical strength and the heat transfer performance are equivalent to an integral space block only made of heat-resistant alloy with a high performance, and the service life is long. When the utility model is used in production, rare and expensive metal materials are saved, and cost of equipment is obviously reduced.
Description
The utility model relates to a kind of Steel Mill and rolls the cushion block that preceding billet heating furnace is used, especially a kind of composite heel block for billet heating furnace.
In a row fixing cylindrical cushion block (button) or slide rail shape cushion block (skid button) on the furnace bottom support beam of stepping beam type billet heating furnace, described cushion block is to support the key part that is heated steel billet and guarantees the steel billet heating quality.Heating zone and the used cushion block of soaking zone at process furnace generally adopt the cobalt-base alloy material monolithic to make, so the cost costliness.In order to reduce equipment cost, adopt composite block.Composite block is made up of upper and lower two portions, and top is called the cushion block head, still adopts cobalt-base alloy or other high performance refractory alloy manufacturing, and the lower section is called the cushion block seat, the manufacturing of available high temperature steel cheaply.In the prior art, be linked together by physical construction between cushion block head in the composite block and the cushion block seat.This mechanical attachment structure makes the integral rigidity variation of this composite block on the one hand, be easy to generate displacement between upper and lower at work two portions, can cause the accident of cushion block head loose or dislocation under the effect repeatedly of the high temperature in process furnace and the heavy duty of steel billet, on the other hand, this mechanical attachment structure makes between cushion block head and the cushion block seat and has the gap, form bigger thermal resistance section, heat on the cushion block head can not in time pass away by the cushion block seat, and makes the cushion block head because of serious compression set of temperature superelevation on it or breaking-up.Therefore, the composite block of this physical construction connection is promoted the use of.
The purpose of this utility model is to improve the deficiencies in the prior art, provides a kind of integral rigidity good, and physical strength and heat transfer property are suitable with single whole cushion block made from high performance refractory alloy, and the composite heel block for billet heating furnace that manufacturing cost obviously reduces.
For achieving the above object, the utility model is taked following design: composite heel block for billet heating furnace includes cushion block head and cushion block seat two portions, and described cushion block head is provided with the cushion block seat is folded mutually up and down, is provided with the metallurgical binding articulamentum between its adjacent facets.
Described composite block can be a cylindrical shape, also can be the slide rail shape.
Composite block for cylindrical shape, adjacent facets between described cushion block head and the cushion block seat can be made one respectively has the solid of revolution boss of protrusion to have the pit of the indent surface of revolution that is complementary with described boss to constitute co-axial concavo-convex mutually nested structure with another, with described axis normal or crossing adjacent facets on be provided with described metallurgical binding articulamentum.Boss between described cushion block head and the cushion block seat and pit can be made the coaxial rotating face of shapes such as the cone surface that matches each other, anchor ring, plane, described adjacent facets is provided with described metallurgical binding articulamentum, and the cross-sectional area of the cushion block that the area of described metallurgical binding articulamentum is occupied is at least 50%.Above-mentioned metallurgical binding articulamentum can obtain by the method for friction welding.
For columniform composite block, also can be provided with pit on the adjacent facets separately between described cushion block head and the cushion block seat, described two pits are combined between described cushion block head and the cushion block seat mutually constitutes chamber when cushion block head and cushion block seat are folded mutually up and down when being provided with, and are provided with described metallurgical binding articulamentum in the described chamber.This metallurgical binding articulamentum can obtain by the electroslag molten welding method.
For slide rail shape composite block, can be made as banded plane on the adjacent facets separately between described cushion block head and the cushion block seat, also can be set to banded concave surface etc., make between the described adjacent facets when being provided with and constitute the gap when cushion block head and cushion block seat are folded mutually up and down, be provided with described metallurgical binding articulamentum in the described gap.This metallurgical binding articulamentum can obtain by the electroslag molten welding method.The cross-sectional area of the cushion block that the area when described metallurgical binding articulamentum is banded is occupied is at least 70%.
This metallurgical binding articulamentum can obtain by the electroslag molten welding method.
The composite block that is provided with the metallurgical binding articulamentum between the adjacent facets of described cushion block head and cushion block seat provided by the utility model is connected to metal successive one by described metallurgical binding articulamentum securely with the cushion block head of the material systems such as cobalt-base alloy of costliness with the cushion block seat of lower-cost heat-resisting steel, compare the integral rigidity that has improved this kind composite block greatly with the composite block that existing machinery combines, solve the effect that existing composite block is subjected to the static load of steel billet and moving load at work and produced displacement, even the problem of loose or dislocation, the heat transfer property of the composite block of metallurgical binding articulamentum connection simultaneously and list are suitable with the heat transfer property of the whole cushion block that heat-resisting allay materials such as cobalt-base alloy are made, guaranteeing under the prerequisite of the cost that greatly reduces cushion block that the temperature height on the cushion block head is suitable, solved existing composite block and caused overheated serious compression set and destroyed problem on the cushion block head, the work-ing life of having improved the cushion block head because of the mechanical bond context layer has space thermal conduction difference.Therefore, the composite block that the utility model provides has that integral rigidity is good, physical strength is suitable with single whole cushion block made from the high performance heat resistant alloy with heat transfer property, the advantage of obvious reduction of manufacturing cost and long service life is promoted the use of in rolling mill furnace and can be saved rare expensive greatly and obviously reduce equipment cost.
