Abstract
The invention discloses a preparation method for a molten steel surface heat preservation agent. The heat preservation agent comprises 15%-55% of CaO, 25%-60% of Al2O3, 6%-40% of MgO and 2%-10% of SiO. The preparation method is suitable for steel ladle molten steel surface covering heat preservation, rapid laying can be achieved on the surface of molten steel to form a three-layer structure, secondary oxidation and heat radiation of the molten steel are avoided, and harmful inclusion on the surface of the molten steel is adsorbed. Slag adhering, cylinder-packing etching and incrustation are avoided, the service life of a steel ladle is prolonged, using is easy, and the labor intensity of workers is relieved.
Description
Technical field
The present invention relates to a kind of collocation method of molten steel surface heat preserving agent.
Background technology
Rounded grain heat preserving agent for liquid steel be a kind of for ladle, take charring rice husk as the rounded grain heat preserving agent for liquid steel of base-material, with flyash, expanded graphite etc. for filler, each component is formulated by a certain percentage, again by the rounded grain of the mode of production formation of specialty, be finished product after packaging, its for shape is reasonable, lightweight, be not tied up with, the Grcular particles of insulating agent for molten steel that free from environmental pollution, spreadability good, high insulating effect, cost are low, but common heat preserving agent can react with the Al in molten steel, causes product defects.
Summary of the invention
The object of this invention is to provide a kind of collocation method of molten steel surface heat preserving agent.
The technical solution used in the present invention is: a kind of collocation method of molten steel surface heat preserving agent, and the component ratio of heat preserving agent is: CaO:15%-55%, Al
2o
3: 25%-60%, MgO:6%-40%, SiO: 2%-10%.
As a further improvement on the present invention, the melting layer thickness of heat preserving agent is 11-18mm.
The invention has the beneficial effects as follows: the present invention is applicable to the insulation of ladle molten steel surface coverage, can sprawl rapidly at molten steel surface, forms three-decker, prevents secondary oxidation of steel and heat radiation, the harmful field trash in absorption molten steel surface.Not dross, not etch cylinder-packing, does not crust, and extends ladle service life, uses simple, alleviates labor strength.
