example 1

[0032] Mix 58wt% of ordinary fly ash and 2wt% refractory clay and grind it to below 200 mesh to prepare base material, then mix and stir the obtained base material with 40wt% silica sol binder to prepare refractory High temperature billet coating.

example 2

[0034] The ordinary fly ash of 53wt% and the refractory clay of 5wt% are mixed and ground to below 200 orders to prepare the base material, then the base material obtained is mixed and stirred with the potassium sodium water glass binder of 42wt% to Preparation of high temperature resistant billet coatings.

example 3

[0036] 45wt% of ordinary fly ash and 15wt% of refractory clay are mixed and ground to below 200 meshes to prepare the base material, and then the obtained base material is mixed with 40wt% aluminum dihydrogen phosphate binder and stirred to Preparation of high temperature resistant billet coatings.

Abstract

The invention discloses a billet coating and a preparation method thereof. The billet coating comprises a base stock and a binder, and the base stock comprises coal ash and refractory clay, wherein the content of the coal ash is 45wt% to 58wt%, the content of the refractory clay is 2wt% to 15wt%, and the content of the binder is 40wt% to 45wt%.

Description

technical field [0001] The invention relates to a steel billet coating and a manufacturing method thereof, in particular to a steel billet coating for preventing the steel billet from being oxidized and decarburized during high-temperature heat treatment and a manufacturing method thereof. Background technique [0002] Before rolling, the steel billet usually needs to be heat-treated in a heating furnace, and then enters the rolling mill to be rolled into various required steel products. During the high-temperature heat treatment process of the billet, the surface of the billet is easily oxidized and decarburized, which not only affects the surface quality of the billet, but also increases the rolling loss of the steel. [0003] In order to solve the problem of oxidation and decarburization of the billet during heat treatment, there are usually two solutions, one is to coat the billet surface with billet paint to form a coating, and the other is to use protective gas (such a...
