The utility model relates to a fining furnace bleed-out alarm device, in order to prevent bleed-out, an anti-leakage disc is mounted at the bottom of a tank in an existing fining furnace, the height of the anti-leakage disc is increased as the difference of tons of molten steel, the height of a vacuum tank is also increased, and the weight and the cost of the device are increased. The fining furnace bleed-out alarm device comprises a vacuum tank body, wherein the bottom of the vacuum tank body is provided with a bleed-out channel, a bleed-out alarm device is arranged on the bleed-out channel, and the bleed-out alarm device comprises a middle pipeline, a transition flange, an armoring electric thermocouple and an aluminum closing plate, wherein the bleed-out channel of the vacuum tank body and the middle pipeline of the bleed-out alarm device are connected through the transition flange, the armoring electric thermocouple is arranged in the bleed-out alarm device, and the outlets of the bleed-out channel and the bleed-out alarm device are provided with the aluminum closing plates. The firing furnace bleed-out alarm device has simple and practical structure, lowers cost, and has the function of monitoring alarm in real time.

Description

A kind of refining furnace bleed-out warning device
Technical field
The utility model relates to a kind of refining furnace bleed-out warning device.
Background technology
In the present employed refining furnace, processed steel ladle hangs in the vacuum tank, covers vacuum container cover and carries out vacuum outgas (or oxygen decarburization) processing; In order to prevent a jar interior ladle bleed-out, usually at the jar inner bottom part anti-drain cap is installed, anti-drain cap, it is the box-structure that is designed to cuboid according to handled molten steel volume, because an anti-drain cap is installed in jar, make the height of former vacuum tank increase and it highly increases also different along with the difference of handling the molten steel tonnage; For the large-tonnage refining furnace, highly increasing the weight that makes vacuum tank increases a lot, adds the weight of anti-drain cap self, will certainly increase the weight and the cost of equipment greatly.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, practical, reduced cost, the refining furnace bleed-out warning device of real-time monitoring alarm function is arranged.
The technical solution of the utility model: a kind of refining furnace bleed-out warning device, comprise vacuum tank, it is characterized in that: the bottom of described vacuum tank is provided with the bleed-out passage, and the bleed-out passage is provided with the bleed-out warning device.
Described bleed-out warning device is by intermediate conduit, counter flange, armoured thermocouple, aluminium shrouding enough become, the bleed-out passage of vacuum tank is connected by counter flange with the intermediate conduit of bleed-out warning device, armoured thermocouple is arranged in the bleed-out warning device, and the outlet of bleed-out passage bleed-out warning device is provided with the aluminium shrouding.
Described armoured thermocouple is arranged in the thermocouple seat by clamp nut, O RunddichtringO and pressure ring.
Described aluminium shrouding is installed in the outlet of bleed-out warning device by the transition Connection Block.
Advantage of the present utility model: simple in structure, practical, reduced cost, real-time monitoring alarm function is arranged.

The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, Fig. 2: existing refining furnace bleed-out warning device, processed ladle water is called in the vacuum tank, cover vacuum cover and carry out vacuum outgas or oxygen decarburization processing, for preventing a jar interior ladle bleed-out, at the jar inner bottom part anti-drain cap is installed usually, anti-drain cap is the box-structure that is designed to cuboid according to handled molten steel volume, in by refractory brick it is divided into several parts so that the melting once more of steel ingot.
Referring to Fig. 3, Fig. 4 is a structural representation of the present utility model, and the bottom of the utility model vacuum tank 1 is provided with bleed-out passage 2, and bleed-out passage 2 is provided with bleed-out warning device 3.
Referring to Fig. 5, Fig. 6, Fig. 7, bleed-out warning device 3 is made of center-aisle 7 counter flanges 4, armoured thermocouple 5, aluminium shrouding 6, the bleed-out passage 2 of vacuum tank 1 is connected by counter flange 4 with the intermediate conduit 7 of bleed-out warning device, can change the bleed-out warning device at any time by dismounting counter flange 4; Armoured thermocouple 2 is arranged in the bleed-out warning device 3, measure a jar interior temperature, send signal if can report to the police to master-control room immediately when bleed-out (above 300 ℃) occurring, armoured thermocouple 5 is by clamp nut 8, O RunddichtringO 9 and pressure ring 10 are arranged in the thermocouple seat 11, with the vacuum seal that guarantees whole tank body and the convenient disassembly of thermocouple 5, the outlet of bleed-out passage bleed-out warning device 3 is provided with aluminium shrouding 6, aluminium shrouding 6 is installed in the outlet of bleed-out warning device by transition Connection Block 12, because the fusing point of aluminium is low, thereby be connected sealing with aluminium shrouding 6 at the end face of counter flange, in order to guarantee the vacuum leakproofness of equipment, special end face with the transition Connection Block is designed to sharp boss pattern, utilize the hardness of aluminium sheet low, realize the metal sealing by bolt and packing washer.
Referring to Fig. 8, during normal the smelting, the sealings at different levels of bleed-out warning device guarantee the vacuum leakproofness of tank body, make steel flow to the bleed-out mouth if design inclination refractory brick during bleed-out in the jar, because liquid steel temperature is greater than the fusing point of aluminium, molten steel burns aluminium and flow to along jar outer refluence mouth in sealing and build in the accident bleed-out hole that refractory material is arranged 13, reduces the damage to tank body and ladle, is convenient to cleaning and secondary smelting.On the bleed-out checkout gear temperature monitor is housed, can monitor a jar interior temperature in real time, can directly accept heat alarm, send in real time, report to the police, take emergency measures from master-control room in case bleed-out takes place, avoid other involuntary maneuver when accident takes place, safety in production.
