Detailed Description
Referring to fig. 1-3, the utility model provides a continuous casting crystallizer, including shell 1 and crystallizer pipe 2, be equipped with on the shell 1 and link up from top to bottom the passageway 3 of shell 1, crystallizer pipe 2 is installed on the passageway 3, be formed with the storage space that is used for storing cooling medium in the shell 1, crystallizer pipe 2 adopts diamond-copper composite to make.
A closed storage space is formed between the shell 1 and the channel 3, so that a cooling medium in the storage space cannot flow out from the channel 3, the crystallizer pipe 2 is inserted into the channel 3, molten steel flows into the crystallizer pipe 2 from the upper end of the crystallizer pipe 2 and flows downwards along the extending direction of the crystallizer pipe 2 when a casting blank is produced, and the molten steel is subjected to heat exchange with the cooling medium in the shell 1 through the crystallizer pipe 2 due to the fact that the cooling medium, such as water, is introduced into the storage space, so that the molten steel is condensed to form a continuous casting blank.
Because the crystallizer tube 2 is made of the diamond-copper composite material, the heat conductivity of the crystallizer tube 2 is as high as 800W/mk, and the heat conduction efficiency of the crystallizer tube 2 is higher than that of the existing crystallizer tube 2 supported by pure copper, the continuous casting billet can be condensed into molten steel in a shorter time.
In a preferred embodiment, the outer surface of the crystallizer tube 2 is provided with a plurality of cooling fins 5 for conducting heat, the cooling fins 5 penetrate through the upper and lower ends of the crystallizer tube 2 along the extending direction of the crystallizer tube 2, and the cooling fins are perpendicular to the outer surface of the crystallizer tube 2; and the channel 3 is provided with a heat radiating groove 4 matched with the heat radiating fin 5.
The outer surface of the crystallizer tube 2 is provided with the radiating fins 5, and the radiating fins 5 can increase the surface area of the crystallizer tube 2, thereby enhancing the heat exchange efficiency of molten steel and improving the condensation efficiency of the molten steel.
The corresponding channel 3 is provided with a heat radiating groove 4 matched with the heat radiating fin 5, when the crystallizer tube 2 is matched with the channel 3, the heat radiating fin 5 is matched with the corresponding heat radiating groove 4, the heat radiating fin 5 is arranged in the groove of the heat radiating groove 4, the cooling medium is arranged outside the groove of the heat radiating groove 4, and the cooling medium exchanges heat with the heat radiating fin 5 through the heat radiating groove 4, so that the condensation efficiency of the molten steel is enhanced.
Further, the heat sink 5 is made of a diamond-copper composite material. The radiating fins 5 and the crystallizer tube 2 are both made of diamond-copper composite materials, so that the integral manufacture of the radiating fins and the crystallizer tube is convenient, and the heat exchange efficiency is improved.
In a specific embodiment, a plurality of insertion blocks 6 are arranged inside the housing 1, the number of the insertion blocks 6 is equal to the number of the heat dissipation grooves 4, the insertion blocks 6 are connected to the side walls of the channel 3, and the heat dissipation grooves 4 are formed on the insertion blocks 6. The shell 1 is also provided with a water inlet and a water outlet.
In the process of condensing the molten steel, cold water is continuously introduced into the storage space through the water inlet, and the water subjected to heat exchange is discharged from the water outlet so as to continuously carry out heat exchange on the molten steel.
