Embodiment 1

[0042] Such as Figure 5 As shown, a continuous casting machine for molten steel continuous casting of the present invention includes a ladle turret 310, a tundish, a crystallizer 320, and a casting section 330. The ladle turret 310 is provided with two ladle grooves A ladle 311 is installed in the ladle tank, a group of crystallizers 320 are arranged side by side at the bottom of the ladle 311, a drawing section 330 is provided at the bottom of the crystallizer 320, and a support roller 332 is arranged on the drawing section 330; The tundish is arranged between the crystallizer 320 and the ladle 311, the ladle 311 is connected with the tundish through the sliding nozzle, the molten steel flows into the tundish from the ladle 311 through the sliding nozzle, and the sliding nozzle is located in the middle of the tundish; the prestressing mechanism The arc-shaped top 201 of 200 is in contact with the tundish bottom plate 110, and the arc-shaped top 201 applies upward prestress t...

Embodiment 2

[0084] The basic content of this embodiment is the same as that of Embodiment 1, except that the 10-strand billet continuous casting machine of 3#10 machine of a certain company’s No. 1 and Table 2, it can be seen that the distance between the centers of steel bar sleeves 212 is 100 mm, and the diameter of steel bar sleeves 212 is The diameter of the prestressed steel bar 220 is The deformation of the designed prestress applying mechanism 200 is D=70mm, and the designed prestress of the prestress applying mechanism 200 is 500MPa.

[0085] A process of applying prestress to the bottom plate of the tundish in this embodiment:

[0086] The components of heat-resistant concrete are composed according to the following mass parts: 43kg of cement, 25kg of refractory aggregate, 5kg of filler, 8kg of additive, 1kg of antirust agent, 1kg of water reducing agent, and 5kg of water; the above cement is C60 Portland cement , the filler is composed of copper powder, converter wind-quench...

Embodiment 3

[0093] The basic content of this embodiment is the same as embodiment 1, the difference is:

[0094] The components of heat-resistant concrete are composed according to the following mass parts: 40kg of cement, 30kg of refractory aggregate, 8kg of filler, 15kg of additive, 1kg of antirust agent, 1kg of water reducing agent, and 5kg of water; the above cement is C60 Portland cement , the filler is composed of copper powder, blast furnace slag, and gravel in a ratio of 1:1:1, the copper powder is deoxidized copper powder, and the particle size of the filler is continuously graded granular material of 3 to 10 mm. Described additive is made up of water glass and sodium fluorosilicate, and quality is water glass 9kg, sodium fluorosilicate 6kg respectively.

[0095] When the tundish of this embodiment is used for continuous casting, the number of continuous casting furnaces reaches 58 furnaces, which prolongs the service time of the tundish and reduces the frequency of replacement o...

Abstract

The invention discloses a continuous casting machine for molten steel continuous casting, and belongs to the technical field of steelmaking continuous casting in the metallurgical industry. A set of crystallizers are arranged on the lower portion of a steel ladle side by side. A billet-drawing forming section is arranged on the lower portion of each crystallizer. A tundish is arranged between the crystallizers and the steel ladle, the steel ladle is connected with the tundish through a sliding gate, molten steel flows from the steel ladle to the tundish through the sliding gate, and the sliding gate is located in the middle of the tundish. The tundish comprises a tundish body and a prestress application mechanism, and a tundish bottom plate is arranged horizontally. The middle of the prestress application mechanism is bent upwards in an arc shape and makes contact with the tundish bottom plate, and the prestress application mechanism applies prestress to the tundish bottom plate. The prestress applied by the prestress application mechanism to the tundish bottom plate is counteracted with the gravity of molten steel, down-warping deformation of the tundish is controlled, the replacement frequency of the tundish is reduced, and the number of continuous casting heat times of the continuous casting machine is increased.

Description

technical field [0001] The invention relates to the technical field of steelmaking and continuous casting in the metallurgical industry, and more specifically relates to a continuous casting machine for continuous casting of molten steel. Background technique [0002] Continuous casting is the process of directly casting molten steel into shaped steel products through a continuous casting machine. Compared with traditional casting processes, continuous casting greatly shortens the production time and greatly improves work efficiency; in addition, continuous casting has the ability to increase metal yield. The advantages of high yield and reduced energy consumption, simplification of steelmaking production process, shortened process and other advantages. As an important reactor in the continuous casting production process, the tundish plays a role that cannot be ignored whether it is for the smooth progress of the continuous casting operation or for ensuring the quality of th...
