Method and apparatus for purifying the exhaust air of installations for consolidating molten substances

A molten substance is consolidated by being deposited onto a cooling belt which conveys the substance through a space formed between the belt and an overhead hood. The formation of exhaust dust from the substance is minimized by controlling heaters in the hood to vary the temperature along the space such that the saturation pressure in the space closely matches the vapor pressure of the substance as the substance travels through the space. Also, the hood is placed close to the cooling belt to minimize the velocity of vapors emitted from the substance within the space.

The manufacture method of the sealing structure of filler and filler

本发明提供一种能够提高插入到铸模的冷却孔等的衬套的导热性的填充剂及密封结构及其制造方法。将由液态的环氧树脂、粉末状的金属粉末和固化剂构成的填充剂(S)填充到冷却孔(82)内。该填充剂在常温下为液化状态，因此填充作业时容易处理。填充剂在冷却孔(82)和被保持于规定位置的衬套(12)的间隙固化。由于以覆盖该全部间隙的方式固化的填充剂(金属粉末等)使衬套(12)不与冷却孔(82)接触，且使它们之间夹设有金属粉末等，因此热传递效率得以提高。例如当对铸模进行加热处理时，固化的环氧树脂碳化。因此，热传递性强的金属粉末(铜等的粉末)以覆盖上述全部间隙的方式残留，热传递效率因而得以进一步提高。

Mold sealing apparatus and method

몰드 실링 장치 및 방법이 개시된다. 용강을 담는 몰드(200)를 보호하는 커버(300)를 포함하고, 커버(300)의 일측에는 가스 주입 구멍(310)이 형성되고, 가스 주입 구멍(310)을 통해 가스 노즐(400)이 삽입된 후 불활성 가스가 주입되어 용강 재산화를 방지한다. 따라서 용강의 재산화를 방지해서 몰드(200)에 의한 주조 공정에서 용강 품질을 향상시킬 수 있고, 용강 품질을 향상시켜 주조 공정에 의해 생산되는 제품의 신뢰도를 높이는 장점이 있다. A mold sealing apparatus and method are disclosed. Includes a cover 300 that protects the mold 200 containing molten steel, a gas injection hole 310 is formed on one side of the cover 300, and a gas nozzle 400 is inserted through the gas injection hole 310 After being used, inert gas is injected to prevent reoxidation of molten steel. Therefore, the molten steel quality can be improved in the casting process by the mold 200 by preventing reoxidation of the molten steel, and there is an advantage of improving the reliability of the product produced by the casting process by improving the molten steel quality.
