Dual-roller thin-belt casting rolling analog equipment as well as usage and control method thereof

Abstract

The invention provides a simulation equipment of twin-roll strip roll casting, which comprises a medium-frequency induction furnace, an online gas supplying apparatus, a temperature field measuring device near the surface of an online crystallization surface and an online molten pool temperature measuring device. The structure of the simulator of the equipment is that a bottom support, a track of the medium-frequency induction furnace and a limiting stop are disposed on the base plate, two vertical sliding bars are arranged between the bottom support and an upper horizontal channel steel stage, each sliding bar is provided with a big sliding barrel capable of sliding along the bar, an upper cross beam and a lower cross beam are connected between two big sliding barrels, the channel steel stage is equipped with a hydraulic equipment, the hydraulic equipment and the lower cross beam are connected by screws, a casting mold is fixed on a small sliding block by a rapid expansion link, the small sliding block can slide on the lower cross beam, roller on the small sliding block can roll along a curved guide rail to drive the casting mold to move, the curved guide rail is fixed on a supporting board which is fixed in a groove on the inner side of the bottom support. By simulation experiments, matching relationship of each processing parameter in roll casting process can be obtained. The invention is used to direct actual commercial manufacture.

Description

technical field [0001] The invention relates to a simulation device, in particular to a casting-rolling simulation device and its use method and control method. Background technique [0002] With the introduction of concepts such as reduction, conservation and circular economy, the iron and steel industry has paid more and more attention to the issue of scrap steel reuse. Scrap steel generally contains a large amount of impurity elements such as P, Cu, Sn, Pb, Zn, etc., and it is often very difficult to remove them from scrap steel. In the national key basic research, it is proposed that when scrap steel is processed for reuse, rapid solidification technology such as twin-roll strip casting and rolling can be used to suppress or even eliminate the macro-segregation of impurity elements in scrap steel, so that the impurity elements can be evenly distributed In the steel, it can save a lot of scrap steel processing costs without reducing the performance of the steel.
