Description
Technical field
The utility model relates to a kind of heat release welding compound test die assembly, and this mould can be in order to test heat release welding compound cooling back slag distribution situation.
Background technology
Along with economic development, the paces of power grid construction are accelerated gradually, and in power grid construction, the grounding net of transformer substation reliability is most important for the safe operation of electrical network, and therefore, the copper covered steel grounded screen of a new generation just progressively replaces hot-galvanized steel grounded screen.The installation position multidigit of grounded screen adopts arc welding, gas welding that the shortcoming that the equipment carrying is inconvenient, need auxiliary facility is all arranged in field environment.So the heat release welding is a kind of suitable welding manner, and the joint of copper covered steel grounded screen is copper, steel composite material, heat release welding in the past is often at copper-copper sleeve, steel-steel joint.And needing the development of new welding compound for the welding of copper-steel composite material joint, the welding quality of novel welding compound is relevant with following factor, i.e. the impurity in the joint and the distribution of slag.Formula development does not in the past all have special-purpose test mould, and test method is extensive simple and crude, and is poor for the reflection intuitive of above-mentioned factor.Therefore, need a kind of test mould to test the center tap quality by the visualize welding compound, in order to carry out the welding compound design.
The utility model content
In order to solve the problem of no special-purpose test mould in the existing formula test, the utility model provides a kind of copper covered steel joint heat release welding compound test mould assembly that carries out specially, use this mould can be used for testing slag and distribution of impurities in the metal of cooling back, can improve the accuracy of test and the efficient of test.
In order to achieve the above object, the utility model adopts following technical scheme: welding mould assembly is made of fusion crucible parts and slag distribution test parts two parts.
The fusion crucible parts are the key reaction parts, and welding compound reacts therein and forms molten metal liquid.
Slag distribution test parts are the cooled slag distribution situation of test motlten metal parts, and it can show vertical distribution situation of slag, impurity intuitively.
Concrete scheme is as follows:
This die assembly comprises fusion crucible parts and slag distribution test parts two parts.Described fusion crucible parts comprise a reaction chamber.Described slag distribution test parts are one to be communicated in the test chamber of described reaction chamber, test chamber comprises slag test chamber upper cone, slag test chamber cylinder and slag test chamber lower cone from top to bottom successively, slag distribution test parts are left and right sides die sinking, and slag distribution test parts die sinking face passes test chamber.
Reaction chamber in the described fusion crucible parts comprises reaction chamber upper cone and reaction chamber lower cone two parts from top to bottom successively.
The cone angle of the reaction chamber upper cone in the described fusion crucible parts is less than the cone angle of reaction chamber lower cone.
The cone angle of described slag test chamber lower cone is less than the cone angle of slag test chamber upper cone.
The utlity model has following advantage:
1) particular manufacturing craft of test slag and Impurity Distribution can be directly used in slag and profile of impurities analysis by this die test result, in order to flux constituent is adjusted, improves the slag distribution situation;
2) motlten metal liquid slag in process of setting is easy to solidify near the conical surface of slag test chamber lower cone, and the slag test chamber by taper can effectively show the slag distribution situation;
3) the slag test chamber makes the easier demoulding of ingot after solidifying by the array configuration of two cones and a main body.
