Abstract
The utility model relates to coils special for a large induction furnace, which have a function of detecting the resistance values of a furnace leakage and guarantee the connecting strength between the inner sides of the coils and fire-resistant daub layers. The coils special for the large induction furnace comprise induction furnace coils. A plurality of brass screws are welded on the inner sides of the induction furnace coils. The coils special for the large induction furnace have the advantages that 1 a plurality of brass screws welded on the inner sides of the induction furnace coils not only greatly increase the connecting fastness between furnace linings and the coils, but serve as detecting probes of the furnace lining resistance values; 2 according to the detection by the detecting probes of the furnace lining resistance values, the working condition of the furnace linings can be known at any time, thereby ensuring the electromagnetic induction furnace to be always in a safe condition.
Description
Technical field
The utility model relates to a kind of runout of detection resistance value function that both had, and can guarantee the special-purpose coil of a kind of large-scale induction furnace of bonding strength between coil inboard and the refractory mortar layer again, belongs to the special-purpose coil of large-scale induction furnace and makes the field.
Background technology
The special-purpose coil of existing induction furnace, on structural design, the refractory mortar layer of about tens millimeters thick of coil inboard knotting one deck is as the permanent furnace lining of coil, add metallic conduction net or metallic conduction silk in its inboard again, and and hearth electrode form runout resistance value test side.Its weak point is: the one, and complex structure; The 2nd, make loaded down with trivial details; The 3rd, the bonding strength between furnace lining and the coil is low, and segregation phenomenon easily takes place.
The utility model content
Purpose of design: avoid the weak point in the background technology, design a kind of runout of detection resistance value function that both had, can guarantee the special-purpose coil of a kind of large-scale induction furnace of bonding strength between coil inboard and the refractory mortar layer again.
Design: induction melting furnace be a kind of be the energy with the electricity; commercial plant by the electromagnetic inductive heating principle molten metallic material; be widely used in the foundry of steel mill and factory; belong to the industrial electro heater and make the field; the special-purpose coil of large-scale induction furnace then is the heart of large-scale induction furnace; it is made of coil and the refractory mortar layer and the burner hearth molten metal detection head that are positioned at the coil inboard; when the molten metal that is positioned at burner hearth touches brass screw; brass screw is passed to the runout alarm with detected signal; the runout alarm is promptly reported to the police; and runout alarm instruction electromagnetic induction furnace when reporting to the police is shut down; cut off the electricity supply, reach the purpose of protection electromagnetic induction furnace.Because brass screw and molten steel have certain thickness across refractory masses, resistance value is constant relatively between the two, and when the thickness of furnace lining (refractory masses) changed, the detected resistance value of its brass screw was along with changing; When the furnace lining attenuation; the resistance value of its furnace lining diminishes; the detection electric current increases; furnace lining attenuation is described; remind the operative employee to arouse attention; in case when the electric current that is detected met or exceeded the value that sets, the runout alarm reminded the operative employee need shut down, change furnace lining, thereby has guaranteed that electromagnetic induction furnace is in safe and reliable state all the time.
Technical scheme: the special-purpose coil of a kind of large-scale induction furnace, it comprises the induction furnace coil, the inboard of described induction furnace coil is welded with many brass screws.
The utility model is compared with background technology, and the one, inboard many brass screws welding of induction furnace coil has not only greatly improved the fastness that is connected between furnace lining and the coil, and has the function of furnace lining resistance value detection probe; The 2nd, by the detection of furnace lining resistance value detection probe, can understand the operating state of furnace lining at any time, guaranteed that electromagnetic induction furnace is in safe state all the time.
