Embodiment Construction

[0053] See figure 1 , a kind of processing method that granulated blast furnace titanium slag is made active slag powder, the processing steps of this method are as follows:

[0054] 1. A raw ore pretreatment section:

[0055] Mix the materials evenly, TiO 2 The content is kept at 10-13% to facilitate smooth production.

[0056] 2. B dehydration section:

[0057] The method of combining air-drying and drying is adopted. When drying, the temperature control range of the material itself is not greater than 600-650°C, and the moisture content of the material is controlled at Mt=-15%.

[0058] 3. C classification iron removal and crushing section:

[0059] The materials with qualified moisture are screened with φ30mm or 30mm×30mm grading sieve. After grading, iron is removed from the material on and off the sieve at the same time, and the material on the sieve is crushed to -30mm after iron removal, and enters the main mill ZM together with the material under the grading siev...

Abstract

The invention discloses a process method for preparing palletized blast-furnace titanium slag into active slag powder, belonging to the technical field of environmental protection. The process method is applied in a comprehensive utilization process of solid industrial waste slag after vanadium titanomagnetite is smelted. The product belongs to the professional field of new materials in a building material metallurgic industry. The process method comprises the following steps: a. evenly mixing materials according to the content of TiO2 in the materials; b. dehydrating the materials; c. grading, deironing and crushing to technological requirements and grinding; d. adding grinding additive according to the process requirements when grinding and separating out the slag powder and a mine returning material; e. mixing the slag powder in the step d and powder compound additive, placing into an intermediate bin, dissolving the soluble compound additive into water in regulation, adding into the slag powder on site to form active blending material-active titanium slag powder; and f. grinding the mine return material at one time, carrying out magnetic separation, returning the nonmagnetic materials into step d, carrying out secondary grinding and secondary separation on the magnetic materials and separating out tailing-primary fireproofing material, concentrate, a blast furnace protective agent and a metallurgical additive. The process method is short in flow, low in investment and low in energy consumption and is safe and environment-friendly.

Description

Technical field: [0001] The process is applied to the comprehensive utilization process of solid industrial waste slag after smelting vanadium-titanium magnetite, and belongs to the field of environmental protection technology; the product belongs to the professional category of new materials in the building materials metallurgy industry. Background technique: [0002] The history of vanadium-titanium magnetite smelting in my country has been 40 to 50 years. In the long years, the solid industrial waste generated after smelting has reached about 100 million tons, and the annual output is 5 million tons. The speed increases, and the large and small ravines in the place of production are piled up, which wastes precious land resources and pollutes the environment, waiting for our comprehensive development and utilization. [0003] my country's scientific and technological workers have never stopped research on the comprehensive utilization of titanium slag. Due to the special p...
