Continuous casting machine includes vertical continuous casting machine, vertical bending continuous casting machine, arc continuous casting machine, elliptical continuous casting machine and horizontal continuous casting machine.
What is the method of continuous casting machine connection?
What are the common continuous casting machines?
Why should we pay attention when using continuous casting machine?
Hot charging and direct rolling of continuous casting billets. The continuous casting billet hot charging process refers to the method in which the billet produced by the continuous casting machine is not cooled, but is heated in a heating furnace in a hot state, and then rolled. The continuous casting billet direct rolling process means that the high-temperature billet from the casting machine is directly sent to the rolling mill to be rolled into products without heating or only slightly supplementary heating of the edges.
Oval continuous casting machine: its advantages are that the height is greatly reduced compared with the arc shape, the hydrostatic pressure of the molten steel is low, the amount of the billet is small, the segregation of the internal crack center is improved, and the investment is saved by 20%-30% (compared to the arc shape. shape). However, the inclusions in the molten steel in the mold have almost no chance of floating, so the requirements for the molten steel are strict.
Horizontal continuous casting machine: its advantages are the lowest equipment height, secondary oxidation of molten steel, improved casting quality, no bending and straightening, which is conducive to preventing cracks, simple equipment maintenance, and convenient accident handling, but the tundish The separation of the joint with the mold is expensive, the lubrication between the mold and the billet is difficult, the mold does not vibrate when the billet is drawn, and it is suitable for small billets, various castings, square billets under 200mm, round billets, and special steel.
The reverse taper is to reduce the air gap, accelerate the heat transfer of molten steel and the growth of the billet shell. Usually, the lower section of the mold is smaller than the upper section. If the inverse taper of the continuous casting machine is too small, it will cause the blank shell to break away from the copper wall prematurely, resulting in an air gap, which will reduce the cooling effect, or cause the thickness of the mold shell to be insufficient, resulting in a leakage accident. The squeezing force between the walls is too large to accelerate the wear of the copper walls.
Fujian Xin Yanchuang Technology Co., Ltd.'s business scope: environmental protection flue gas treatment engineering, environmental protection water treatment engineering, furnace manipulator, industrial robot, automatic control technology, biological fermentation equipment, customized machinery design and manufacturing, at the same time with the company's diversified development, gradually expand to domestic and foreign trade and engineering service project construction.
