Hot top billet casting machine
- The continuous semi-continuous steel casting equipment with a composite hot top crystallizer as its core adds a refractory hot top cavity with heating and heat preservation above the ordinary water-cooled crystallizer.
- The molten steel only begins to solidify in the lower water-cooling section, which is specially designed to produce small round billets, small square billets, and precision alloy steel billets.
Hot top casting table
It is the core support workbench of the hot-top semi-continuous casting unit, integrating diversion, heat preservation hot top, water-cooled crystallizer, hydraulic lifting, and ingot dredging supporting structure to realize multi-flow synchronous casting. It is mostly used for the production of precision small round steel billets and aluminum bars.

Working Principle
Molten steel flows into the hot top cavity through an immersion nozzle. The hot top is continuously kept warm to prevent premature crusting of the liquid surface. The molten steel flows downward into the water-cooled copper sleeve, where the outer wall quickly solidifies upon contact with water. The crystallizer vibrates slightly to prevent the billet shell from sticking to the mold. The straightening machine pulls the billet down at a uniform speed. After complete solidification in the secondary cooling zone, it is cut to length. No continuous casting protective slag is required throughout the process, simplifying the procedure.

Advantages
1. Superior Billet Quality: Uniform solidification start point, uniform billet shell thickness, significantly reducing cracks, shrinkage cavities, inclusions, and cold shuts; dense grains; stable liquid surface with no slag entrapment.
2. Suitable for small cross-section precision casting billets: It is specially designed for the production of φ50–160mm round billets and small square billets, effectively solving the defects of traditional casting equipment such as easy steel leakage and rough surface of casting billets when casting small cross-sections.
3. Simplified casting process: No protective slag is required, saving on auxiliary material costs, while avoiding production failures such as slag line erosion and steel sticking.
4. Stable Production: Hot top temperature control within ±10℃, minimal liquid surface fluctuation, wide casting speed range, allowing for continuous casting over extended periods.
5. Lower Wear and Tear: Simple repair of hot top refractory components and water-cooled copper bushings, resulting in longer service life.
Key Points for Using a Hot-Top Billet Casting Machine
Before Casting
1. Check the hot top graphite and refractory layer for damage and leakage.
2. Confirm the crystallizer water circuit is unobstructed and leak-free.
3. Fully preheat the hot top and dry the refractory components.
4. Verify the temperature control, vibration, and casting mechanism.
During Casting
1. Strictly control the molten steel temperature to prevent erosion or blockage.
2. Maintain a stable liquid level and avoid large fluctuations.
3. Adjust the casting speed smoothly and avoid sudden changes.
4. Monitor the cooling water temperature and pressure in real time.
5. Clean the hot top of any sticky steel promptly to prevent overflow.
Maintenance During Shutdown
1. Stop casting and slowly cool down; rapid cooling of water-cooled refractory components is strictly prohibited.
2. Regularly inspect the hot top lining and water-cooled copper sleeve.
