Problems solved by technology

[0002] During casting, in order to ensure the fullness of the casting, it is required that the metal water can smoothly enter the mold through the riser, so that the riser is required to be solidified slowly. In order to improve the shortcomings of the riser heating solidified block in the prior art, this The invention provides a riser coating and its preparation method for improving the deficiencies of existing risers

Embodiment Construction

[0009] The technical solutions of the present invention are described below to facilitate understanding by those skilled in the art.

[0010] The riser coating is composed of the following raw materials by weight: chrome ore 4%, pearl sand 1%, iron oxide 2%, carbon powder 3%, zinc oxide 3%, quartz sand 6%, water 81%.

[0011] The preparation method of the riser coating is to pulverize the chrome ore, pearl sand, iron oxide, carbon powder, zinc oxide, and quartz sand to a powder state through a pulverizer, and place the mixture in the powder state in a mixer to stir and mix evenly. Add water to the mixture and stir well to prepare the riser paint. The riser paint is evenly coated on the surface of the riser, and the thickness of the riser paint on the surface of the riser is not more than 3 mm.

[0012] The invention has been exemplarily described above, and it is obvious that the specific implementation of the present invention is not limited by the above-mentioned methods, as...

Abstract

The invention belongs to the technical field of metal casting and especially relates to riser paint of an exothermic riser for casting and a manufacturing method thereof. The riser paint comprises 2-5% of chromium ore sand, 1-2% of fused ceramsite, 2-5% of iron oxide, 2-5% of carbon powder, 1-3% of zinc oxide, 3-6% of quartz sand and 74-89% of water. The riser paint is coated on a riser. In casting, through the riser paint, a high riser temperature is kept and the riser is not solidified easily so that a liquid metal for casting can smoothly pass through the riser and enter into a mold and thus a molded riser has full appearance and smooth surface and casting quality is improved.

Description

technical field [0001] The invention belongs to the technical field of metal casting, and more particularly relates to a riser paint for a heating riser used in casting and a manufacturing method thereof. Background technique [0002] During casting, in order to ensure the fullness of the casting, it is required that the metal water can smoothly enter the mold through the riser, which requires the riser to solidify relatively slowly. The invention provides a riser coating and a preparation method thereof for improving the deficiencies of the existing risers. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a riser coating that can make the riser solidify slowly and a preparation method thereof. [0004] In order to solve the above technical problems, the present invention provides a riser paint, which is characterized in that it is composed of the following raw materials by weight percentage: 2-5% of chrome ore, 1...
