Abstract
The utility model discloses an electroslag remelting crystallizer, which comprises a copper inner cylinder, a steel outer cylinder, a water inlet pipe, a water outlet pipe as well as an upper flange and a lower flange welded together with the inner cylinder and the outer cylinder, wherein the upper flange consists of an excircle part and an inner circle part, the excircle is made of steel material, the upper half part of the inner circle is made of copper material, and the lower half part is made of steel material; and the lower flange also consists of the excircle part and the inner circle part, wherein the excircle is made of steel material, the upper half part of the inner circle is made of steel material, and the lower half part of the inner circle is made of copper material. In the utility model, the flanges in an 'inner steel and outer copper' composite structure mode are adopted to effectively solve the problem that cracks are generated easily at the joint of copper and steel, and simultaneously, because the copper has the physical characteristics of quick heat conduction, strong electric conduction and good plasticity and the steel has the physical characteristics of strength, toughness, corrosion resistance and the like, the problem that the joint of the inner cylinder of the crystallizer and the flange plane is overheated is solved, and the heat exchange effect is improved; and the strength of the flange is ensured, and the service life of the crystallizer is prolonged.
Description
Technical field
The utility model belongs to the electroslag refining technical field, relates in particular to a kind of esr crystallizer.
Background technology
The esr crystallizer is the key part in the electroslag refining equipment, and it is the raffinate of splendid attire generation institute heat requirement on the one hand, holds the accumulative molten metal; Provide suitable shaped container for solidifying of molten metal on the other hand, so its working conditions is more abominable, except that bearing violent difference variation, still need with holding metal pressure and the pressure of water coolant become, so its quality is had higher technical requirements, cold and hot exchange is effective when being metal remelting post crystallization, self intensity height, non-leakage.
At present, crystallizer adopts red copper and soft steel manufacturing usually, and structure is that internal layer is that red copper, skin are soft steel, and the two butt welding forms cooling water sandwich later on.In reflow process, water coolant is flowed into by crystallizer bottom water inlet pipe, the molten steel in the cooling layer between crystallizer red copper inner bag and outer cover of steel plate, cooling crystallizer, the crystallization velocity of control molten steel forms electroslag ingot, and water coolant flows out from the rising pipe on crystallizer top.The crystallizer of this structure is because inner barrel is copper, outer cylinder body is a steel, inner barrel and outer cylinder body weld together by the steel ring flange, so just easily produce the crack in the copper steel junction, the heat-conductive characteristic of carbon steel is bad simultaneously, and then causing the heat exchange effect of crystallizer bad, seriously shorten work-ing life.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned shortcoming, provides a kind of copper steel weld that can solve to be difficult for that crack, heat exchange effect are good, the esr crystallizer of long service life.
For achieving the above object, the utility model adopts following solution: a kind of esr crystallizer, comprise copper inner barrel, steel outer cylinder body, be arranged on the outer cylinder body bottom water inlet pipe, be arranged on the rising pipe on outer cylinder body top and upper flange and the lower flange that welds together with inside and outside cylindrical shell, it is characterized in that: described upper flange is made of cylindrical and interior round two portions, wherein cylindrical is a steel material, the first half of interior circle is a copper material, and Lower Half is a steel material; Lower flange also is made of cylindrical and interior round two portions, and wherein cylindrical is a steel material, and the first half of interior circle is a steel material, and Lower Half is a copper material.
Above-mentioned esr crystallizer is characterized in that: described inner barrel and upper flange weld together, and outer cylinder body and lower flange weld together, the two relative welding fabrication.
The manufacture method of above-mentioned esr crystallizer is characterized in that: it may further comprise the steps:
(1) makes upper and lower flange: earlier the steel plate cutting is made upper and lower flange shape, Lower Half with circle in the first half round in the upper flange or the lower flange mills away again, and then copper material being welded on the Lower Half round in the first half round in the upper flange or the lower flange is moulding.
(2) make inner barrel: earlier with copper sheet material by blanking, mill limit, volume circle, welding, polishing, whole garden, carry out precision work by large-scale lathe and milling-boring machine again and be made into inner barrel, then inner barrel and upper flange are welded together.
(3) make outer cylinder body: earlier with steel sheet material by blanking, mill limit, volume circle, welding, polishing, whole garden, carry out precision work by large-scale lathe and boring and milling machine again and be made into outer cylinder body, then outer cylinder body and lower flange are welded together.
(4) crystallizer moulding: it is moulding that inside and outside cylindrical shell is welded relatively.
The manufacture method of above-mentioned esr crystallizer; it is characterized in that: described welding adopts gas to protect the weldering mode; shielding gas is a pure argon; flow 20～25L/min; wlding diameter phi 1.6～2.0mm copper welding rod S201 will be at 250 ℃～300 ℃ following preheatings, welding current 350～400A before the weldering; voltage 25～35V, welding speed 150～200mm/min.
Compared with prior art, the present invention has following advantage:
1, because flange of the present utility model has adopted the composite structure form of " the outer copper of interior steel ", the junction of flange and inner barrel is the welding of copper-steel composite material and copper material like this, easily produces problem of cracks so the present invention has solved the copper steel junction effectively.
2, because flange of the present utility model has adopted the composite structure form of " the outer copper of interior steel ", physical property such as both utilized the heat conduction of copper fast, conduction is strong, plasticity is good, the intensity, toughness of steel, physical property such as anticorrosive have been utilized again, so the present invention had both solved the problems of excessive heat of crystallizer inner barrel and Flange Plane junction, improved the quality and the heat exchange effect of crystallizer; Ensure the structural strength of flange again, thereby prolonged the work-ing life of crystallizer.
