Abstract

The invention provides a high-temperature-resisting nanometer anti-oxidization isolating agent for an oriented silicon steel billet and a production method and application method of the high-temperature-resisting nanometer anti-oxidization isolating agent. The high-temperature-resisting nanometer anti-oxidization isolating agent comprises, by weight percent, 5%-10% of carbon powder, 20%-30% of magnesium aluminate spinel powder, 10%-20% of an inorganic binder, 5%-10% of a suspending agent, 5%-10% of an inorganic reagent and the balance magnesite clinker micro powder and inevitable impurities. Compared with the prior art, the formula of the isolating agent is adjusted, a proper production process is adopted, and the high-temperature-resisting nanometer anti-oxidization isolating agent for the oriented silicon steel billet and with stable high temperature stability is obtained; and after a production test, according to the isolating agent, the performance of an oriented silicon steel product is influenced, and meanwhile the burning loss is reduced by 80% or above. The isolating agent has the advantages of being simple in preparing, low in cost and stable in high temperature stability.

Description

technical field [0001] The invention belongs to the technical field of production of high-temperature-resistant and anti-oxidation release agents, and in particular relates to a high-temperature-resistant nano-scale anti-oxidation release agent for oriented silicon steel billets, a production method and a use method thereof. Background technique [0002] The oriented silicon steel billet needs to be heated and softened at high temperature before hot rolling to reduce the rolling deformation resistance. During the heating process of the billet in the heating furnace, the oxidizing gas in the furnace reacts with the Fe element on the billet surface under high temperature conditions to form an oxidation reaction. The iron sheet will cause a certain degree of oxidation and burning loss, which will reduce the yield of steel products. At present, some anti-oxidation release agents cannot be applied in large quantities in the hot rolling production of oriented silicon steel due to ...
