A production method of iron coke for smelting titanium slag and iron coke
A production method and iron coke technology are applied to the production method of iron coke for titanium slag smelting and the field of iron coke, and can solve the problems that the coarse-grained titanium concentrate is difficult to meet the production demand of titanium slag, the matching degree of titanium slag smelting is not high, and the like. The effect of improving utilization, high coordination and high reactivity

Embodiment 1
[0031] Step 1: Select three coking coals with different thermoplastic ranges (the thermoplastic range is 10-100°C), and crush them respectively as raw coal samples;
[0032] The second step: control the moisture content in the raw coal sample to be within the range of 3-5%. If the moisture content in the raw coal sample is high, then dry it, and if the moisture content is low, add moisture;
[0033]Step 3: Mix the three kinds of raw coal samples whose moisture has been regulated in a mixer to obtain a mixed basic coal sample. The proportions of the mixed raw coal samples are in the following order according to the thermoplastic interval of the coal sample: the thermoplastic interval is 70-100 ℃ The dosage of raw coal samples is 10-25%, the dosage of raw coal samples with thermoplastic range of 50-70 ℃ is 30-50%, and the dosage of raw coal samples with thermoplastic range of 10-40 ℃ is 25-60%;
[0034] The fourth step: sieving the ilmenite concentrate, selecting the fine-graine...
Embodiment 2
[0038] Three coal samples with different thermoplastic intervals were selected (the specific industrial analysis and thermoplastic characteristics are shown in Table 1), the thermoplasticity of coal sample A was 99 °C, coal sample B was 62 °C, and coal sample C was 30 °C, and were crushed respectively. Raw coal sample; according to the existing industrial analysis parameters of the coal sample, add moisture to the moisture content of the three coking coals to 4%; mix the three raw coal samples uniformly in the mixer according to the size of the thermoplastic interval to obtain the basic coal sample, the three raw coal samples The mixing ratio of the sample is: coal A-20%, coal B-40%, coal C-40%; the titanium concentrate (the composition is shown in Table 2) is screened, and the fine-grained titanium concentrate with a particle size smaller than 325 mesh is selected as the The additive prepared by iron coke is dried, and then mixed with the mixed coal sample in a mixer evenly, a...
