开发了一种水平轮式连铸机,用以高速浇铸52～85mm小方坯。新铸机的结晶轮轴心与垂直线成3°～5°倾角。从中间包流出的钢水,通过密闭的水口进入结晶槽,避免了钢水被氧化,又省去了钢液面检测及控制装置。在直径3m的试验铸机上,以18～22m/min的速度浇出了50mm×63/67mm的小方坯,其表面及内部质量都令人满意。在此基础上,设计了用以浇铸70～85mm小方坯的水平轮式连铸机,其预期的最高出坯速度为28m/min,并能与高速线材轧机相配合,直接轧制成材。
A horizontal wheel caster was developed to cast 52 to 85 mm billet at high speed. The new casting machine’s crystal axis and the vertical axis into a 3 ° ~ 5 ° angle. The molten steel flowing out of the tundish enters the crystallization tank through a sealed nozzle to prevent the molten steel from being oxidized and eliminates the need for liquid level detection and control devices. On the test caster with a diameter of 3 m, a small billet of 50 mm × 63/67 mm was poured at a speed of 18-22 m / min, the surface and internal quality of which were satisfactory. On this basis, a horizontal wheel caster designed to cast 70-85mm billets was designed with a maximum expected billet speed of 28m / min and is ready for direct rolling in line with high-speed wire rod mills.
