The continuous casting machine can continuously cast high-temperature molten steel into a production process with a certain cross-sectional shape and a certain size and specification.
What is the production process of continuous casting machine?
What are the characteristics of continuous casting machine?
What is straight arc continuous casting machine?
The high-temperature molten steel is continuously poured into one or a group of water-cooled copper molds, and the molten steel gradually solidifies along the periphery of the mold into a billet shell. After the molten steel level rises to a certain height, the billet shell solidifies to a certain thickness. The billet is pulled out, and the billet is completely solidified by water spray cooling in the secondary cooling zone, and is cut to length by the cutting device according to the requirements of rolling. This process of directly pouring high-temperature molten steel into billets is called continuous casting. The emergence of the continuous casting machine has fundamentally changed the ingot rolling process that has dominated for a century. Because it simplifies the production process, improves the production efficiency and metal yield, saves energy consumption, greatly reduces the production cost, and has the advantages of good billet quality and other advantages. In today's steelmaking enterprises, whether it is long-process steelmaking or short-process steelmaking, the equipment of continuous casting machines is almost inevitable.
The main equipment of the vertical continuous casting machine is arranged in a vertical line from the tundish to the cutting station. This type of casting machine occupies a small area and the equipment is compact;
There is no bending deformation of the high temperature billet, and the surface and internal cracks of the billet are few;
Inclusions in molten steel are easy to float;
The structure of the secondary cooling device and the clamping roller is simple and easy to maintain.
The straight arc continuous casting machine adopts a straight mold, and the mold is equipped with a straight line section of 2.5 to 3.5 m. After the billet with a liquid core passes through the straight section, it is gradually bent into an arc shape. The straightening arc caster is exactly the same.
The main advantage:
The advantages of the vertical continuous caster are retained. During the solidification process of the molten steel in the straight mold and its lower straight section, it is conducive to the floating and uniform distribution of large inclusions in the molten steel. It avoids the defect of inclusion enrichment at 1/4 of the inner arc side of the billet, and has obvious effect on the production of high-clean steel;
Since the casting billet is asymptotically bent into an arc shape with a liquid core, the arc continuous casting machine still has the advantages of lower equipment height and lower construction cost.
From 2018 to now, Fujian Xin Yanchuang Technology Co., Ltd. was awarded as a National high-tech enterprise. It has obtained ISO9001 quality system certification and several practical patents. The aim of the company is scientific and technological innovation, strict quality control, efficient service.
