Problems solved by technology

[0003] In the current production process, the tools used for stirring molten aluminum are usually made of cheap carbon steel or graphite. Although both of them have been industrialized, they are directly in contact with high-temperature molten aluminum, causing serious corrosion and large burning loss. It will greatly shorten the service life of the mixing tool, and it is easy to pollute the aluminum liquid

Abstract

The invention discloses a high-temperature-resistant and corrosion-resistant glass coating for agitating molten aluminum. The high-temperature-resistant and corrosion-resistant glass coating is prepared from the following raw materials in percentage by weight: 50 to 70 percent of component-A glass, 15 to 25 percent of component-B glass, 2 to 10 percent of vermiculite, 1 to 5 percent of dispersing agent and 5 to 15 percent of high-temperature binder, wherein the sum of the percentages (by weight) of all the raw materials is 100 percent; the component-A glass is high-temperature glass which can be sintered in situ and has higher glass formation capacity, and is prepared from the following raw materials of strontium carbonate, calcium carbonate, silicon dioxide, boric acid and titanium dioxide; the component-B glass is low-temperature glass with a lower softening point, and is prepared from the following raw materials of aluminum oxide, the boric acid, the sodium carbonate, zinc oxide and the silicon dioxide. The glass coating provided by the invention has favorable corrosion resistance, and is coated on the surface of an agitating head prepared from a carbon steel or stainless steel material; by utilizing the secondary levelling of the component-A glass and the component-B glass, the compactness of the coating can be improved; the performance of the resistance of the agitating head to the corrosion of the molten aluminum is enhanced; the service life of the agitating head is prolonged.

Description

technical field [0001] The invention belongs to the technical field of high-temperature inorganic coatings, and in particular relates to a high-temperature and corrosion-resistant glass coating for stirring aluminum liquid. Background technique [0002] For nearly fifty years, aluminum has become one of the most widely used metals in the world. In the construction industry, aluminum is widely used in metal doors, windows, stair handrails, etc. after being processed into aluminum alloy; aluminum alloy materials are also widely used in the aviation department, national defense and military industry; aluminum cables reinforced with high-strength steel wires are commonly used in power transmission ; In addition, aluminum alloys are also widely used in automobile manufacturing, daily necessities, mechanical equipment and other fields. In order to improve production efficiency and production quality, a stirring device must be used while aluminum is rapidly melting, so that the va...
