Description
Technical field
The present invention relates to a kind of method of utilizing iron alloy breeze production ironmaking with the piece material, it belongs to a kind of technical field with powder briquetting material.
Background technology
Along with developing rapidly of metallurgy industry, occurred as a lot of associated resources such as breeze, dedusting ash.If these associated resources are not made full use of, not only can waste ample resources, also can cause great pollution simultaneously to environment.For addressing this problem, people work out the method for utilizing breeze and dedusting ash to produce cement, though this method has realized utilization to breeze and dedusting ash solid waste, the iron that contains in breeze and the dedusting ash and other metal but have no to utilize, and cause the very big waste of metallic element.Other has some that dedusting ash is entered sintering plant as iron-smelting raw material to carry out sintering, but sintering not only can cause the loss of noble metals such as chromium, nickel, noble metals such as remaining chromium, nickel also can enter in the molten iron of smelting simultaneously, cause hot metal composition not conform to, the use of influence back step operation.Sintering process has also increased the operation expense in addition, has improved ironmaking cost.
Summary of the invention
The objective of the invention is to solve the existing method of handling breeze and dedusting ash and exist the serious and high technological difficulties of processing costs of metallic element waste, provide a kind of iron alloy breeze and ironmaking dedusting ash utilization ratio height, cost low utilize the iron alloy breeze production ironmaking method of piece material.
The present invention for the technical scheme that solves above-mentioned technological difficulties and adopt is: a kind of method of utilizing iron alloy breeze production ironmaking with the piece material, it comprises the following steps:
1) batching: iron alloy breeze, ironmaking dedusting ash, coke powder, Sodium salts humic acids and polyvinyl alcohol are prepared burden by following weight percent:
Iron alloy breeze 10～80%, ironmaking dedusting ash 0～70%, coke powder 0～15%, Sodium salts humic acids 5～15%, polyvinyl alcohol 5～10%;
2) stir: above-mentioned raw materials is mixed the back stirred 30～50 seconds, in compound, add weight then again and be 13～15% water of compound weight, continue to stir 130～180 seconds;
3) moulding: delivering to the compound that stirs in the shaper and being pressed into density is 2.5～3g/cm
3Moulded products;
4) oven dry: the moulded products that suppresses 80～150 ℃ down oven dry 8～12 minutes moisture content to the goods be 5～10%.
Described iron alloy breeze is any one in manganeseirom breeze, ferrochrome breeze, Rhometal breeze, ferro-silico-manganese breeze and the ferro-silicon breeze.
Because the present invention has adopted technique scheme, the iron alloy breeze mixing process stirring, moulding and oven dry with other raw material after, dedusting ash is made block elements with smelting iron, reduce the heating calcining process, both saved the production cost of ironmaking, can not reduce the performance of ironmaking again, comprise low temperature intensity and hot strength, also made full use of the association waste resource that produces in the metallurgical process, prevented environmental pollution.Therefore, the present invention have that technology is simple, production efficiency is high, cost is low, iron alloy breeze and ironmaking dedusting ash utilization ratio is high and advantages such as suitable scale operation.
