Background technology
Utilizing the temperature changing process in the continuous temperature measurement technology for detection blast furnace hearth, to instruct blast furnace operating, is the advanced method that domestic and international in recent years blast furnace is imagined employing always.But because blast furnace itself is an airtight reactor, the furnace cylinder working inclement condition, except that can observing at air port place in the stove the tuyere zone situation, all the other can only by see slag, see iron, material speed and relatively by the analysis-by-synthesis of various instrument, could judge the working of a furnace indirectly, and then adopt an effective measure.Up to the present, only retrieve three pieces of patents relevant with blast furnace temperature, application number is 02212863.8 and 02110077.2 " blast furnace lining ablation monitor and monitoring method thereof ", is to be embedded in the mode that lead in the furnace wall reports to the police and to point out furnace lining ablation situation to blow, and can not continuous temperature measurement; The 3rd piece is number of patent application 99241371.0 " Thermo detector for blast furnace ", and it can only measure the temperature on iron-smelting blast furnace top, and temperature is low herein, and the device of energy continuously tested high temperature cupola well layer temperature does not appear in the newspapers.
Summary of the invention
The purpose of this utility model provides a kind of temperature changing trend that can be used for the continuously measured blast furnace hearth, and have high temperature resistant, be able to bear strong corrosion, anti-reduction, adapt to the cupola well temperature measuring equipment of advantages such as working of a furnace changing capability is strong.
The purpose of this utility model is realized by following scheme.
1. temperature measuring equipment is made up of pure graphite carbon brick, high temperature heat-resistant galvanic couple; The physical dimension of pure graphite carbon brick is laid bricks similar to blast furnace hearth;
2. thermopair is arranged in pure graphite carbon brick axial centre groove; The thermopair top flushes with the portion of pure graphite carbon brick; Be full of high-temperature-resistant adhesive between thermopair and the pure graphite carbon brick;
3. the skin of the thermocouple wire in thermopair cover alundum tube insulation, its tail end are stretched out the supporting computer data processing system in last furnace shell and outside and are connected.
The inside and outside protective tube of thermocouple wire is an alundum tube, partly is enclosed within the stainless steel tube by connecting furnace shell.
The thermopair optimal selection is two celion thermopairs.
Contact in the box that is tightly connected on the thermocouple wire outer end is passed furnace shell and is fixed on stove outer covering is connected, and contact is connected with outside display system by lead-in wire in the connecting box.
The pure graphite carbon brick that contains two celion thermopairs is installed on the horizontal plane of iron notch.
The blast furnace hearth continuous temperature measuring function can be realized and finish to the utility model, and the temperature of the furnace hearth variation tendency accurately is provided, and instructs blast furnace man author correctly to judge the working of a furnace, improves the economic benefit that blast furnace is produced.Have advantages such as high temperature resistant, anticorrosive, safe and reliable, good combination property, less investment.
