ABSTRACT OF DISCLOSURE A direct chill casting of metals, particularly hot top casting of aluminum and its alloy, is improved by applying a gas pressure to the metals from directly below the overhang of a feed reservoir for receiving a melt to be cast. The direct chill casting is further improved by supplying a lubricating oil from a slit for conveying the gas to the inner wall of the mold. By using the process and the apparatus according to the invention, ingots having excellent smooth surfaces and reduced segregation can be reliably produced with a reduction in the amount of the lubricating oil used.
