Embodiment

[0041] Make two sets such as figure 1The shown submerged nozzle heating rotating device is respectively installed on the bottom of the tundish B2 of the first and second flow submerged nozzles of the continuous casting machine in the steel plant. The specific installation method is as follows:

[0042] (1) Install the submerged nozzle and adjust the center of the submerged nozzle;

[0043] (2) The sensor passes through the submerged nozzle, and then the sensor body is fixed on the bottom of the tundish with the mounting bracket on it, and the coaxiality error between the center of the sensor body and the center of the submerged nozzle is not greater than 3mm;

[0044] (3) Connect the sensor to the cooling device, connect the sensor to the control system, and connect the temperature measuring device to the signal of the control system.

[0045] The submerged nozzle B1 is a split nozzle with an outer diameter of φ80mm and a total length of 1250mm. The electrical parameters of ...

Abstract

The invention provides an immersion type water hole heating rotating device. The device comprises a control system, and further comprises an inductor and a temperature measuring device, wherein the inductor is arranged at the outer side of an immersion type water hole in a sleeving mode, and is connected to the bottom of a tundish; the temperature measuring device is arranged beside the immersiontype water hole, and is electrically connected to the control system; a coil which is wound at the outer side of the immersion type water hole and is in the shape of a tapered solenoid is arranged inthe inductor, and the diameter of the coil is gradually reduced from top to bottom; and the coil is electrically connected to the control system. Compared with the prior art, the immersion type waterhole heating rotating device provided by the invention realizes controlling the temperature and a flowing way of molten steel which enters a crystallizer once by heating molten steel in the immersiontype inlet and controlling a molten steel flowing way, is small in energy consumption, and can greatly reduce the temperature of a bale and can homogenize the temperature of molten steel in the crystallizer. The invention further provides a working method of the immersion type water hole heating rotating device.

Description

technical field [0001] The invention relates to heating and braking of molten steel in a submerged nozzle on a tundish, belongs to the technical field of iron and steel metallurgy, and in particular relates to a submerged nozzle heating and rotating device and a working method thereof. Background technique [0002] The iron and steel continuous casting machine includes a large ladle, a tundish and a crystallizer. The ladle is located in the upper section of the tundish for delivering molten steel to the tundish; the crystallizer is located in the lower section of the tundish, and the tundish is immersed in The type nozzle delivers molten steel to the crystallizer. In iron and steel continuous casting, low superheat and constant temperature pouring is the goal pursued, and the temperature of molten steel entering the mold is a key indicator, which has an inevitable impact on the quality of the billet. However, in the existing equipment, there is no device structure for contr...
