Embodiment 1

[0031] A kind of composite molten steel purifier of embodiment 1

[0032] The composite molten steel purification agent of the present embodiment is a composite sphere, and the composite sphere is composed of an inner core and an outer shell. The inner core is composed of 30 parts of aluminum ash, 30 parts of barium oxide, 5 parts of titanium dioxide and 35 parts of water glass, wherein the modulus of water glass is 3.1-3.5. The shell is composed of 80 parts of calcium carbonate, 10 parts of magnesium carbonate and 10 parts of composite binder, and the mass ratio of the inner core to the outer shell is 1:2. The preparation method of this composite molten steel purifying agent specifically comprises the following steps:

[0033] (1) Material preparation: weigh the raw materials of the above-mentioned inner core and outer shell according to weight components, and then place them in an oven at 100-110° C. to dry for 4 hours, and set aside.

[0034] (2) Preparation of the inner ...

Embodiment 2

[0038] Embodiment 2 A kind of composite molten steel purifying agent

[0039] The composite molten steel purification agent of the present embodiment is a composite sphere, and the composite sphere is composed of an inner core and an outer shell. The inner core is composed of 80 parts of aluminum ash, 10 parts of barium oxide, 10 parts of titanium dioxide and 20 parts of water glass, wherein the modulus of water glass is 3.1-3.5. The shell is composed of 10 parts of calcium carbonate, 80 parts of magnesium carbonate and 10 parts of composite binder, and the mass ratio of the inner core to the outer shell is 4:1. The preparation method of the composite molten steel purifying agent is the same as that of Example 1, with specific reference to Example 1, the difference is that a composite sphere is sprayed with an organic waterproof coating to obtain a composite molten steel purifying agent. The organic waterproof coating is a silicone rubber waterproof coating, and the thickness...

Abstract

The invention discloses a composite molten steel purifying agent and a preparation method thereof, and relates to the technical field of steelmaking. The composite molten steel purifying agent is a composite sphere, wherein the composite sphere is composed of an inner core and a shell, the inner core is composed of aluminum ash, barium oxide, titanium dioxide and water glass, the shell is composed of calcium carbonate, magnesium carbonate and a composite binder, and the mass ratio of the inner core to the shell is (1-2):(0.5-2). According to the composite molten steel purifying agent, the raw materials are easy to obtain, the preparation method is simple and easy to operate, the cost is low, inclusions in molten steel can be rapidly removed, the functions of slag making, deoxidation, desulfurization and dephosphorization are achieved, and the purification degree of the molten steel is greatly improved. The solid waste slag aluminum ash is effectively utilized, so that the production cost is greatly reduced, and the purposes of energy conservation and environmental protection are achieved while the purification effect is guaranteed.

Description
