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 in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0020] Such as figure 1 Shown:

[0021] Step 1: According to the evaluation requirements of titanium furnace protection effect, input dynamic TiO in titanium 2 Income items, recorded as a and TiO in titanium 2 Expenditure item, recorded as b, and measuring the residual thickness of the hearth side wall carbon brick at the same time, recorded as d; the purpose is to calculate the titanium deposition rate of the blast furnace hearth, clarify the current titanium income and expenditure of the blast furnace hearth and the blast furnace hearth security status.

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

Abstract

The invention discloses a method for judging the furnace protection effect of a blast furnace hearth. According to the method for judging the furnace protection effect of the blast furnace hearth, thefurnace protection effect is judged by calculating the deposition rate of titanium ore in a blast furnace, a furnace protection index is calculated by comparing the thicknesses of carbon bricks on the side wall of the blast furnace hearth, and the furnace protection effect is evaluated.

Description

technical field [0001] The invention relates to a method for judging the furnace protection effect of a blast furnace hearth, which belongs to the field of blast furnace ironmaking, and specifically relates to a model for evaluating the furnace protection effect of titanium ore and a method for predicting the titanium load of the furnace protection. Background technique [0002] The blast furnace is the most economical and efficient main reaction vessel in the ironmaking process. The longevity of the hearth is the most important problem faced by the blast furnace since its long-term development. Especially under the current conditions of lack of ore resources and high-intensity smelting, the longevity 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 solve the problem of blast furnace hearth longevity, and achieved remarkab...
