{"product_id":"hot-tops","title":"Hot Tops","description":"\u003cdiv\u003eHot Tops are insulating and exothermic refractory sleeves used in ingot casting to control solidification and reduce shrinkage defects. Installed over the feeder head, Hot Tops help maintain molten metal temperature in the upper portion of the ingot, allowing proper feeding during solidification.\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003eBy restricting primary and secondary piping within the hot top zone, they help produce sound ingots without internal shrinkage cavities. Hot Tops improve steel yield by reducing metal loss in the feeder head and minimizing rejections caused by piping defects. Their controlled insulation and exothermic properties sustain heat in the riser area, ensuring continuous molten metal feeding until final solidification.\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003eHot Tops also improve productivity by reducing cropping length, optimizing feeder head size, and enhancing casting efficiency. They are widely used in carbon steel, alloy steel, and special steel ingot production where yield improvement and defect reduction are critical.\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003eManufactured with silica-based composition, controlled density, and low moisture content, our Hot Tops provide reliable thermal stability and safe handling during casting operations.\n\u003cp dir=\"ltr\"\u003e \u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eTypes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003e1.
