Abstract

The invention relates to an electric furnace applicable to a thermal state experiment of blast-furnace cooling staves with different sizes. The technical scheme is as follows: the electric furnace applicable to the thermal state experiment of the blast-furnace cooling staves with different sizes consists of a furnace bottom (1), a furnace wall (2), a group of heating pipes (3), a cooling stave (4), an embedded brick (5) and a bearing frame (6), wherein the furnace wall (2) is a combined furnace wall with adjustable lengths and widths; the group of heating pipes (3) are installed in through holes of the furnace wall (2); the cooling stave (4) is installed on the bearing frame (6) by bolts (7) and forms a hearth together with the furnace wall (2). The electric furnace is applicable to cooling staves with different sizes, and has the characteristics of accurately controlling experimental temperature, being convenient to operate, safe and environmentally-friendly, and the like by adoption of electrical heating.

Description

technical field [0001] The invention belongs to the field of stave thermal state experimental furnaces, in particular to a stave thermal state experimental furnace in the bosh area of ​​a blast furnace. Background technique [0002] The thermal test is an important means to study the temperature distribution and heat flux of the stave under different conditions. my country's stave thermal test started relatively late. In 1999, Beijing University of Science and Technology built the first stave thermal test furnace in Changshu Nozzle Field, and Shantou Huaxing Metallurgical Spare Parts Factory built the second domestic stave test furnace. All experimental furnaces are heated by burning diesel in the combustion chamber. Such a vertical experimental furnace has disadvantages such as high overall height of the furnace, inconvenient operation, environmental pollution caused by flue gas, difficulty in controlling the temperature in the furnace, and the need to re-build the experime...
