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 pass through the riser and enter the interior of the mold, so that the riser is required to solidify slowly. 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 the understanding of those skilled in the art.

[0010] The main raw materials and components of the riser paint are: 4% Luo ore sand, 1% pearl sand, 2% iron oxide, 3% carbon powder, 3% zinc oxide, 6% quartz sand, and 81% water.

[0011] The preparation method of the riser coating is to pulverize Luo ore sand, pearl sand, iron oxide, carbon powder, zinc oxide, and quartz sand into a powder state through a pulverizer, and place the mixture in the powder state in a mixer to stir and mix evenly. Water is added to the well-mixed mixture, and the riser coating can be prepared by sufficient stirring. The riser coating is evenly coated on the surface of the riser, and the thickness of the riser coating on the surface of the riser is not more than 3 mm.

[0012] The invention has been described as an example above, and it is obvious that the specific implementation of the present invention is not...

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 specifically relates to a riser coating 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 pass through the riser and enter the interior of the mold, so that the riser is required to solidify slowly. The invention provides a riser paint and a preparation method thereof for improving the deficiencies of the existing riser. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a riser paint capable of making the riser solidify slowly and a preparation method thereof. [0004] In order to solve the above-mentioned technical problems, the present invention provides a riser coating, which is characterized in that: the main raw materials and components thereof include: ...
