Molten iron jar melting agent and preparation method and application thereof

[0013] The preparation method of described iron ladle canned iron agent, comprises pretreatment, preparation step, specifically comprises:

[0014] A. Pre-treatment: prepare materials according to the formula of ferric agent in molten iron tanks, pulverize anthracite and long-flame coal for later use, and purchase industrial salt and aluminum powder for later use;

[0015] B. Preparation: weigh the pulverized anthracite, long-flame coal, industrial salt and aluminum powder according to the formula ratio, mix and stir evenly to obtain the target product.

[0016] The particle size of the anthracite and long-flame coal is 1 mm to 3 mm, accounting for more than 90%.

[0017] The ladle canned iron agent is added into the iron can before putting iron in the blast furnace, adding 200kg to 500kg each time.

[0018] The inventive method, main definition, principle are as follows:

[0019] 1) Definition of ferric oxide

[0020] After adding the iron agent in the molten iron tank, a vio

[0027] Grind long-flame coal and anthracite for later use; purchase industrial salt and aluminum powder for later use; weigh 50 kg of long-flame coal, 20 kg of anthracite, 25 kg of industrial salt, and 5 kg of aluminum powder, and add them into a mixer to mix well to obtain Target.

[0029] The anthracite is crushed for later use; the industrial salt and aluminum powder are purchased for later use; 50kg of anthracite, 35kg of industrial salt, and 15kg of aluminum powder are weighed proportionally, added to a mixer and mixed to obtain the target product.
