Problems solved by technology

So far, only three patents related to blast furnace temperature have been retrieved. The application numbers are 02212863.8 and 02110077.2 "Blast Furnace Lining Ablation Monitoring Device and Monitoring Method", which are prompted by burning the wire buried in the furnace wall. The furnace lining is ablated, and the temperature cannot be continuously measured; the third article is the patent application number 99241371.0 "Blast Furnace Temperature Measuring Device", which can only measure the temperature of the upper part of the ironmaking blast furnace, where the temperature is low, but it can continuously test the blast furnace hearth There is no report on the device for layer temperature

Embodiment Construction

[0024] Depend on figure 1 , 2 It can be seen that the furnace hearth 5 is located at the lower part of the furnace body, the iron mouth is located in the furnace hearth 5, the outer layer of the blast furnace stave 4 is the furnace shell, the inner layer of the blast furnace stave 4 is a refractory brick, and the special pure graphite carbon Brick 2 is similar to other refractory bricks, just like other refractory bricks, but it should be built on the horizontal line 9 of the center of the blast furnace taphole; thermocouple 1 is located on the central axis of pure graphite carbon brick 2, and the front end of thermocouple 8 is connected with the front end of pure graphite carbon brick. 7 flush; can directly measure the temperature in the hearth; thermocouple 1 uses double graphite carbon fiber thermocouple to make full use of its high temperature resistance; in order to prevent leakage, connect the double graphite carbon fiber thermocouple 1 and pure graphite carbon brick 2 ...

Abstract

A device for continuously measuring the temp of furnace hearth in blast furnace is composed of a thermoelectric couple with dual graphite carbon fibers, a pure-graphite carbon brick containing said thermoelectric couple at its axial center position, and a display system. Said pure-graphite carbon brick is installed to the furnace wall on a horizontal level with the tap. Its advantages are continuous measuring, high resistance to high temp and corrosion, and low cost.

Description

Technical field [0001] The invention belongs to test equipment in iron and steel smelting, in particular to a blast furnace hearth device in iron smelting and its manufacturing method Background technique [0002] Using continuous temperature measurement technology to detect the temperature change process in the blast furnace hearth to guide the operation of the blast furnace is an advanced method that has been conceived and adopted by blast furnaces at home and abroad in recent years. However, since the blast furnace itself is a closed reactor and the working conditions of the hearth are harsh, except for the observation of the tuyere area in the furnace at the tuyere, the rest can only be observed by looking at slag, iron, comparing material speed and comprehensively using various instruments. Analysis can indirectly judge the furnace condition, and then take effective measures. So far, only three patents related to blast furnace temperature have been retrieved. The appli...
