A kind of evaluation method of blast furnace hearth protection effect

A technology for blast furnaces and blast furnaces, which is applied to the evaluation of the furnace protection effect of the blast furnace hearth. It can solve the problem that the evaluation method cannot reflect the furnace protection effect of the hearth in real time in the evaluation model of the titanium ore furnace protection effect and the titanium load prediction field of the furnace protection. , Unable to provide guidance for blast furnace titanium ore furnace protection, and the effect of furnace protection lags behind, etc.

Problems solved by technology

[0004] At present, the hearth protection effect is mainly reflected from the hearth side wall temperature and carbon brick residual thickness. However, the traditional evaluation method cannot truly and real-time reflect the hearth protection effect. Therefore, it is urgent for ironworkers to propose a new evaluation method for blast furnace hearth protection effect, and it is of great significance to guide blast furnace operation

Embodiment Construction

[0019] A specific embodiment of the invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0020] like figure 1 shown:

[0021] Step 1: According to the evaluation requirements of the effect of titanium protection furnace, input the dynamic TiO in titanium 2 Income item, recorded as a and TiO in titanium 2 The expenditure item, recorded as b, and the residual thickness of carbon bricks on the sidewall of the hearth at the same time, recorded as d; the purpose is to calculate the titanium deposition rate of the blast furnace hearth, to clarify the current income and expenditure of titanium in the blast furnace hearth and the blast furnace hearth Safe state.

[0022] Step 2: Calculate the titanium deposition rate of the blast furnace hearth by the formula for the sorted titanium data: Deposition of TiO in the furnace 2 ...

Abstract

The invention discloses a method for judging the furnace protection effect of a blast furnace hearth. The evaluation method for the furnace protection effect of a blast furnace hearth is: by calculating the deposition rate of titanium ore in the blast furnace, the furnace protection effect is judged, and the furnace protection effect is judged by the blast furnace furnace. The furnace protection index was calculated by comparing the thickness of the carbon bricks on the side walls of the cylinder, and the furnace protection effect was evaluated.

Description

technical field [0001] The invention relates to a method for evaluating a furnace protection effect of a blast furnace hearth, belonging to the field of blast furnace ironmaking, in particular to a furnace protection effect evaluation model for titanium ore and a furnace protection titanium load prediction method. Background technique [0002] The blast furnace is the most economical and efficient main reaction vessel in the ironmaking process. The longevity problem of the hearth is the most important problem faced by the blast furnace for a long time. Especially under the current conditions of lack of ore resources and high-intensity smelting, the longevity problem of the blast furnace needs to be solved urgently. . [0003] With the improvement of blast furnace ironmaking technology, blast furnace workers have adopted blast furnace hearth maintenance operations to address the longevity problem of blast furnace hearth, which has achieved remarkable results and effectively i...
