Description
Technical field
The invention belongs to Equipment for Heating Processing and Technology field
Background technology
Salt bath furnace is the heat treatment furnace a kind of commonly used that utilizes salt bath medium heated parts, salt is solid state when room temperature, solid salt is non-conductive, so general usually salt bath furnace must adopt auxiliary starting resistance earlier the salt around the working electrode to be fused into liquid salt when starting, fused salt is connected another working electrode again, utilize the resistance heat effect of fused salt that fused salt is warmed up to working temperature, and all melt the back at salt and from burner hearth, take out starting resistance, and then carry out the thermal treatment work of workpiece, again starting resistance is put back to after hours in the salt bath furnace and arrived the normal temperature state, repeat above step next time when working again with the stove cooled and solidified.Its technological operation trouble, the workman works slight big, and influences working efficiency.In addition, the existing used starting resistance of salt bath furnace work is generally with the spirrillum of Φ 16～20mm low-carbon (LC) round steel coiled or folding band shape and makes, and its shortcoming is that yielding easily blowing causes the work stagnation and influence production schedule.
Summary of the invention
Purpose of the present invention provides a kind of assistant starting resistance that do not need just in order to solve the deficiencies in the prior art, only needing to adopt working electrode can start salt bath furnace heats up, can also make salt bath furnace keep working order, top-buried type salt bath furnace started by working electrodes easy and simple to handle, as can to reduce labor strength.
The objective of the invention is to be achieved through the following technical solutions.
Top-buried type salt bath furnace started by working electrodes is embedded with opposing L shape left side working electrode, right working electrode and the middle working electrode between left working electrode and right working electrode at burner hearth bottom; Left side working electrode, right working electrode and middle working electrode are steel plate stack both ends welded construction, and the stage casing is folded with insulating concrete mica plate between synergetic every two-layered steel plates; Vertically be inserted with along the furnace wall three groups match one by one be provided with enter electrode and contacts electrode, three pairs of bottoms that enter electrode and contacts electrode are respectively at being connected with left working electrode, right working electrode and middle working electrode, the furnace wall is stretched out on the top; Be horizontally connected with dismountable copper bar on three contacts electrode tops, three enter electrode and are connected with power supply.
Salt bath furnace of the present invention offers notch on three contacts electrode tops, and copper bar is installed in the notch.Between three vertical notches of contacts electrode and the copper bar that snaps fits into, be fitted with wedge.
Salt bath furnace of the present invention has buried contacts electrode and has entered electrode owing to the top, make three working electrodes that are positioned at burner hearth bottom can replace the assistant starting resistance starting salt bath furnace of prior art, make the solid salt fusing, can make salt bath furnace keep working order as working electrode again.Owing to do not have ad hoc starting resistance, avoided prior art because the yielding shut-down problem that causes of easily blowing of starting resistance.And therefore contacts electrode and enter electrode and introduce along the furnace wall from stove top can not produce the problem of furnace wall slit source salt.
Salt bath furnace of the present invention is simple in structure firmly, and long service life is easy to operate, has alleviated working strength of workers greatly.
