Description
Technical Field
The utility model belongs to the mould casting field, concretely relates to casting core surface fire resistant coating's quick system of brushing.
Background
In the core casting process, in order to improve the surface quality of a casting, a layer of refractory material is usually coated on the surface of a core to improve the surface heat resistance, chemical stability, molten metal scouring resistance, sand adhesion resistance and the like. Along with the improvement of the surface quality requirement of castings, the application of refractory coatings is more and more important, and the refractory coatings are technical measures for preventing the castings from generating surface defects such as iron sticking, sand inclusion, sand holes, air holes and the like, reducing the workload of sand cleaning, improving the labor environment, reducing the cost of the castings and improving the economic benefit, and become one of important modeling materials indispensable in casting production.
The function of the fire-resistant coating is as follows:
1. and the sand sticking of the casting is prevented. The heat-resistant coating can seal a large number of pores on the surface of the core to form a barrier with higher compactness, fire resistance and thermochemical stability, and can effectively prevent the infiltration or thermochemical reaction of molten iron, thereby preventing the generation of sand sticking of castings and reducing the labor amount of cleaning the castings and surface treatment of subsequent castings.
2. And the surface roughness of the casting is reduced. After the surface of the mold core is coated with the refractory coating, the surface is smoother and more compact, the mold core is not easily wetted by molten iron, and the roughness of the surface of a casting can be reduced.
3. And reinforcing the surface of the core. The coating with certain strength and permeability can obviously improve the surface strength of the core, improve the anti-scouring capability of the core and reduce the heat radiation of molten iron to the core, thereby effectively preventing and reducing the defects of casting sand holes, sand inclusion and the like caused by scouring and thermal expansion.
4. Shielding and isolation. The dense refractory coating creates a barrier between the core box molten iron, thereby preventing the undesirable effects of the pyrolysis products of certain resins on the surface of the casting.
5. Alloying the surface of the casting and refining the grains. The alloying of the surface of the casting can be realized by adding some special alloys into the coating.
The traditional casting sand surface fire-resistant coating is brushed, and after the core making of the core shooting machine is completed, the core shooting machine is carried to a brushing platform in a manual carrying and hoisting mode. Manually dipping the refractory coating with a brush, and manually rotating the brushing device to enable the brush to be tightly attached to the surface of the core, so that the core is brushed for one circle. And moving the brush until brushing, and repeatedly brushing the mould core. And after the local repair, manually moving away from the brushing table.
The disadvantages of brushing with this method are:
1. the labor of workers is strong. Repeated handling of the core and painting operations consumes worker physical effort.
2. The labor environment is poor. The painting work is completely finished manually, workers contact the fire-resistant paint in a close distance, volatile substances of the paint are absorbed by human bodies, and the paint contacts the skin of the workers, so that the paint is not beneficial to health and the working environment is worsened. ,
3. the working efficiency is low. The manual coating is not formed in one step and can be carried out after multiple coating and repairing, the working efficiency is low, the time for coating a sand core is long, two persons need to carry when a large-scale core is encountered, and the two persons can carry out coating together.
4. The painting effect is poor. The manual painting mode has uneven thickness of the paint, and the phenomenon of paint dripping or incomplete painting often occurs.
