In addition to chemical composition, the cast rolling plate quality mainly includes grain size, gas and slag inclusion. In addition to the proportion of electrolytic aluminum liquid and solid material will affect the internal quality of cast rolling plate, the melt refining is the key. In order to make the gas and slag in molten […]

In order to cooperate with the cooling and increasing speed of casting and rolling, based on the increase of the nozzle roll gap, the flow pattern of the nozzle must be improved to make the flow field, temperature field and concentration field in the tip cavity uniform. Due to the cooling and increasing speed of […]

In order to cooperate with the cooling and speeding of casting and rolling, the cooling intensity must be increased to ensure the heat balance in production. Due to the increase of the casting-rolling speed, the defect of sticking rolls is very easy to appear. The aluminum sticking on the part or the entire width of […]

Increase the gap on nozzle and rolls, optimize the nozzle flow pattern, help eliminate the longitudinal streak defects, and improve the surface quality of the cast-rolled strip. The surface features of the longitudinal stripes are defects that run through the entire length of the cast-rolled sheet. The longitudinal stripes are bright bands, sometimes deep. The […]

Lowering the front box temperature and increasing the casting-rolling speed can not only improve production efficiency, but also improve melt fluidity and melt solidification conditions, and increase the internal density of the cast-rolled coil. In production, ensuring the temperature of the smelting furnace, the standing furnace, and the caster tip and nozzle of the standing […]

Molten aluminum on cleanliness, that is, reducing the inclusion of the aluminum melt, is a very important factor in the production of high-quality products. The inclusions in the aluminum alloy make the alloy structure discontinuous, reduce the compactness of the product, cause corrosion and cracks, and reduce the mechanical properties of the final product. Molten […]

There are many reasons for porosity in casting of die casting aluminum alloy, so we must find out the reason to solve the problem. Porosity in Casting Porosity Caused by Improper Die Casting Parameters In the process of liquid aluminum die casting, if the filling speed is too fast, the gas in the mold cavity […]

The degassing process in aluminum alloy melting process can reduce the gas content in the molten aluminum and prevent the gas from precipitating during the solidification of aluminum alloy. If the gas content in liquid aluminum is very low, the amount of gas precipitated during solidification will be reduced, and the bubbles generated will also […]

The main function of the on-line degassing system is to remove hydrogen dissolved in molten metal, and the secondary function is to remove alkali metals and inclusions. The selection of on-line degassing equipment is related to the functionality of the final casting product. According to the humidity conditions in the ambient atmosphere, the on-line degassing […]

Rotating degassing method, also known as bubble floating method, is the most advanced and effective purification method. The active gas chlorine, or inert gas argon and nitrogen, or flux mixture gas are introduced into the aluminum melt to form bubbles. The alkali metals and inclusions in the melt undergo chemical reactions through adsorption contact, so […]
