Description
Technical Field
The invention relates to a special coating for a hot steel billet marking machine, belonging to the technical field of metal material surface spraying.
Background
With the rapid development of the steel industry, metal castings are more and more widely applied under the condition of high-temperature working conditions. After the continuous casting and drawing billet comes out, the surface is required to be marked, and the steel mixing event of various materials caused by unclear marks is eliminated. The marking materials applied at present in China comprise paint, aluminum wires and copper wires. In practical application, the temperature of the coating can generally resist about 300 ℃, and the effect is not ideal when the temperature is higher than 300 ℃, because the components are generally phenolic aldehyde, modified epoxy coating and organosilicon coating, the temperature resistance is poor, and the coating is inflammable. And materials such as aluminum, copper and the like have high cost, a large amount of electric energy needs to be consumed to dissolve the materials into liquid to spray, the mechanical failure rate is high, and the actual production requirements cannot be met.
Disclosure of Invention
In order to solve the existing problems, the invention provides a special coating for a hot steel billet marking machine, which can resist high temperature up to 2000 ℃.
The purpose of the invention is realized by the following technical scheme: the special coating for the hot steel billet number spraying machine is characterized by comprising, by weight, 10-15% of nano titanium dioxide, 2-5% of nano zirconium oxide, 2-5% of sodium dihydrogen phosphate, 5-10% of nano barium sulfate, 5-15% of nano rare earth micro powder, 2-5% of a dispersing agent, 2-5% of aluminum sulfate and the balance of water.
The preferable mixture ratio is as follows: 15% of nano titanium dioxide, 5% of nano zirconium oxide, 3% of sodium dihydrogen phosphate, 10% of nano barium sulfate, 10% of nano rare earth micro powder, 2% of dispersing agent, 3% of aluminum sulfate and 52% of water.
The special coating for the hot steel billet marking machine comprises the following preparation methods: the preparation method comprises the steps of preparing the raw materials except water according to the ratio by metering, premixing the prepared raw materials for 3-5 minutes by using stirring equipment, adding water for stirring, stirring for 10-20 minutes to obtain a coating, and filling by using a filling machine.
The invention has the beneficial effects that: the invention adopts the scheme, is an innovation for the high-temperature coating, and the selected materials have heat resistance and non-combustibility. When the paint is used, the paint and the surface of steel react quickly to generate an inorganic polymer with a three-dimensional structure, the coating and the surface of steel are connected into a whole, and the paint is used for spraying codes, labels and handwriting marks clearly, is wear-resistant and waterproof and is not easy to fall off. No toxicity and pollution, and its temp. resistance is up to 2000 deg.C. The spray gun is suitable for high-temperature environments of steel plants, can be applied to imported and domestic various spray gun lengths, does not block the spray gun, is non-toxic, environment-friendly, pollution-free, flame-retardant and antioxidant. The steel mixing accident caused by unclear marks in the steel plant is completely avoided.
