The application provides a continuous casting production method of tinplate, which comprises the steps of dynamic control of a pulling speed, linkage control of cooling, dynamic adjustment of an insertion depth of a submerged nozzle and dynamic argon blowing, wherein the pulling speed control is based on the maximum section steel flow, the target pulling speed is calculated reversely according to the actual section, and the steel flow of each section is constant; the cooling water flow is compensated in linkage with the increment of the pulling speed, and the bulging of the shell is inhibited; the insertion depth of the nozzle adopts a one-way increasing insertion mode from shallow to deep in multiple stages; and the argon blowing flow is adjusted in stages according to the fluctuation of the crystallizer liquid level. The application can reduce the nozzle clogging area by more than 50%, the standard rate of liquid level fluctuation is increased to 95%, the continuous casting castability and the surface quality of the casting blank are significantly improved, and the application is suitable for the efficient and stable continuous casting production of tinplate and other aluminum-containing steels.

The utility model belongs to the technical field of roller casting equipment, and particularly relates to multi-channel type roller casting equipment which comprises three casting equipment bodies, a base is arranged at the bottoms of the casting equipment bodies, three auxiliary plates are evenly connected to the top end of the base, and the three auxiliary plates are arranged on the base. An annular groove is formed in the top end of the auxiliary plate, and through holes are formed in the top end of the base and the top end of the auxiliary plate. The multi-channel type roller casting equipment has the advantages that bubbles in pouring liquid are effectively promoted to rise to the surface and break, and therefore the defects of bubbles, gaps, air holes and the like in a casting after the pouring liquid is solidified are remarkably reduced; the compactness and the overall quality of the casting are improved, the pouring liquid is more uniform in the solidification process due to vibration, and the phenomena of stress concentration and non-uniform solidification caused by local premature solidification are avoided. The mechanical performance of the casting can be improved, and the surface quality and the size precision of the casting can be improved.

The utility model relates to a temperature control device for bridge cable hot casting anchor anchoring material casting, relates to the device of hot casting anchor anchoring material casting, including at least one installation dynamic heat preservation device on the anchor cup, dynamic heat preservation device includes annular sleeve, heat preservation device, temperature sensor, control system, the inner hole of annular sleeve is covered on the outer surface of anchor cup, heat preservation device, temperature sensor are installed in the closed cavity of annular sleeve respectively, the signal output end of temperature sensor is connected with the signal input end of control system, the signal output end of control system is connected with heat preservation device, the utility model discloses through heat preservation device can make the anchoring material in the anchor cup keep proper temperature, solve the problem of the insufficient compactness caused by the big void ratio of anchoring material and the uneven casting, further promote the anchoring efficiency, can also reduce the thermal stress crack in the cooling process of casting, significantly improve the anchoring material quality.
