Problems solved by technology

At this time, the temperature of the steel billet is very high, and it is impossible to obtain a clearly visible and firm mark with conventional inkjet printing paint. Therefore, it is necessary to develop a paint and a special inkjet printing device for high temperature steel billet logo inkjet printing to meet the process requirements.

Embodiment Construction

[0017] According to the high-temperature billet mark spray printing coating of the present invention, by TiO 2 , MgO, SiO 2 , Fe 2 o 3 Composed of, the weight percentage of each component is: TiO 2 :MgO:SiO 2 : Fe 2 o 3 = 55~60: 15~30: 10~15: 0~0.5, burning loss≤1.

[0018] The materials in the above weight percentages are mixed, the viscosity of the materials is controlled at 14-18s, the particle size is controlled at 300 mesh ± 10 mesh, and the pH value at room temperature is controlled at 1-2. The density of this paint is 1.3±0.05 kg / dm 3 , solid content ≥ 45%.

[0019] The paint is loaded into the pressure vessel through the feeding port of the special printing device. By adjusting the air pressure, the sprayed paint is atomized and printed on the billet to form a pure white billet mark.

[0020] This coating is suitable for printing various high-temperature billet marks.

Abstract

The present invention provides a paint for spray-printing high-temp. billet mark, its composition comprises (wt%) 55-60% of TiO2, 15-30% of MgO, 10-15% of SiO2, 0-0.5% of Fe2O3 and caustic soda is less than or equal to 1. The viscosity of said material is controlled in 14-18s, grain size is controlled in 300 meshes plus or minus 10 meshes, and its normal temp. pH value can be controlled to 1-2, and the density of said paint is 1.3 plus or minus 0.05 kg / cu.dm and its solid content is greater than or equal to 45%. Its spray-printed mark is pure white, has strong adhesive force, good acid resistance, alkali resistance, wet fastness and good fluidity, etc. Said invention also discloses its specially-designed spray-printing device, and said paint can be spray-printed on the billet with 200-1400 deg.C.

Description

technical field [0001] The invention belongs to a high-temperature paint, in particular to a paint for high-temperature billet mark spray printing, which is suitable for spray-printing marks on high-temperature steel billets. Background technique [0002] The billet mark is a kind of mark printed on the side of the billet, which is used to mark the melting number, steel type, production date and other information of the billet. At the same time, it is also used to trace possible problems in the previous process. [0003] In modern steelmaking production, steel billets are mainly produced by continuous casting machines, and once the steel billets are cast, they are required to be printed with marks immediately before delivery. At this time, the temperature of the steel billet is very high, and it is impossible to obtain a clearly visible and firm mark with conventional inkjet printing paint. Therefore, it is necessary to develop a paint for high temperature billet logo inkje...
