Continue Casting Direct Rolling Technology (CCDR) is a steel rolling process in which liquid steel is poured into a continuous casting machine to cast a billet (called continuous casting billet) and then rolled directly into a hot rolling unit without cooling after holding in a heating furnace for a certain period. This technology cleverly combines the casting and rolling process, compared with the traditional casting billet after the heating furnace heating and then the rolling process has the advantages of simplifying the process, improving labor conditions, increasing the metal yield, saving energy, improving the quality of continuous casting billet, and facilitating mechanization and automation.
punching technology uses specific Continuous Casting and Rolling technology and equipment to manufacture lead strips. It then expands the lead strips through different punching equipment to make a Continuous mesh grid with a characteristic mesh structure. Since multiple Continuous rolling processes make the Continuous lead strip, a fine and high-density metal grain structure occurs in the lead strip during production.

The automatic production line of continuous casting and rolling mainly consists of continuous casting machine, soaking furnace, hot continuous rolling unit and laminar cooling.
The production capacity of a set of CCDR equipment is equivalent to 18 sets of gravity casting equipment. It saves over 50% energy, and the operators is reduced to 1 /10.
Since the thickness of the grid made by Punching can be less than 0.8mm, its weight is lightening 20-40% while maintain the same level of performance
AUFRAME adopts the latest AUFRAME Grid technology in the industry, a battery with good high-temperature resistance, a more compact structure, and stronger corrosion resistance. High density, good electrical conductivity, stereoscopic grid structure, lead paste fixed more firmly, longer service life, more energy-saving, and more environmentally friendly.
From the comparison of the metallographic structure of the positive grid, it can be found that the grain structure of the continuous casting and rolling positive grid is more refined, and a large number of fine metallographic structures can be observed. Grain refinement helps to slow down the intergranular penetration corrosion of the grid, and is beneficial to enhance the bonding strength of the grid and the lead paste.
The CCDR Grid (by Punching), tensile strength, hardness, and corrosion resistance are better. The internal structure is more compact, and the grains are more refined and uniform. The microstructure is improved (The defects such as bubbles, shrinkage holes, porosity, and casting cracks on the surface and inside the grid are reduced).
Every internal corner of the grid in the frame is kept consistent, strong, and flexible structure. It’s easier to make grids of various thicknesses according to technical requirements.
The products of the same model (same structure, exact cost) are produced by Gravity, Expanded, CCDR technology.

Continuous casting and continuous grids have obvious advantages in electrochemical corrosion resistance and mechanical properties because of fewer microstructure defects and more refined and uniform grains and are suitable for clean and efficient production. Therefore, the excellent performance of the continuous casting and continuous grid makes it the first choice for the positive grid of the start-stop battery.
