Abstract

폐주물사를 주원료로 하여 혼합물을 만들어 성형하여 가마에 2회정도 구워서 제(諸)도로용재 및 내화벽돌을 만드는 것으로, 산업폐기물을 주원료로 하기 때문에 폐기물처리 및 재활용측면에서도 자원재활용 효과가 크다 하겠다.The waste casting sand is used as the main raw material, and the mixture is molded and baked twice in the kiln to make the road material and the refractory brick. Since the industrial waste is the main raw material, the resource recycling effect is also great in terms of waste treatment and recycling.

Description

Manufacturing method of firewood and fire brick using waste foundry sand and loess soil

본 발명은 연약지반매립용 등으로 사용되는 폐주물사를 자원의 재활용차원에서 산업폐기물인 폐주물사를 제(諸)도로용재 및 내화벽돌로 재활용 하고자 함이다. 본 발명의 구체적내용은 하기(下記)와 같다.The present invention intends to recycle waste foundry sand, which is an industrial waste, as a road material and refractory brick in order to recycle waste waste sand used for landfilling of soft ground. The specific content of this invention is as follows.

1). 폐주물사를 5mm의 철망으로 거른다.One). The waste foundry sand is filtered through a 5mm wire mesh.

2). 황토흙을 5mm의 철망으로 거른다.2). The ocher soil is filtered with a 5mm wire mesh.

3). 1)과 2)를 70 : 30의 비율로 섞고 물을 부어 혼합물을 만든다.3). Mix 1) and 2) in the ratio of 70:30 and pour water to form a mixture.

4). 3)을 제조용 성형틀에 부어 가압하여 성형물을 만든다.4). 3) is poured into a mold for manufacturing to press to make a molded product.

5). 성형물을 72시간 자연건조 시킨다.5). The moldings are allowed to dry for 72 hours.

6). 자연건조된 성형물을 가마에 넣고 가마내의 온도가 섭씨 800도까지 도달하도록 굽는다.6). The naturally dried moldings are placed in a kiln and baked so that the temperature in the kiln reaches 800 degrees Celsius.

(가마내의 온도가 섭씨 800도까지 도달하는 시간은 6시간이다.)(The time for the temperature in the kiln to reach 800 degrees Celsius is six hours.)

7). 가마내의 온도가 섭씨 200도까지 내려가면 성형물을 꺼낸다.7). The mold is removed when the temperature in the kiln drops to 200 degrees Celsius.

8). 성형물에 유약을 바르고 가마에 넣어 가마내의 온도가 섭씨 1200도까지 도달하도록 굽는다.8). Glaze the moldings and place them in a kiln to bake until the temperature in the kiln reaches 1200 degrees Celsius.

(가마내의 온도가 1200도까지 도달하는 시간은 12시간이다.)(The time for the temperature in the kiln to reach 1200 degrees is 12 hours.)

9). 가마내의 온도가 섭씨 200도까지 내려가면 성형물을 꺼낸다.9). The mold is removed when the temperature in the kiln drops to 200 degrees Celsius.

상기(上記)의 발명은 산업폐기물인 폐주물사를 자원으로 활용함으로써, 폐기물의 처리 및 자원의 재활용측면에서도 효과가 크다 하겠다.The above invention is effective in terms of waste treatment and recycling of resources by utilizing waste foundry sand which is industrial waste as a resource.

Claims

The waste foundry sand and ocher soil are mixed at 70:30, poured into water to make a mixture, and then molded. After natural drying, the oven is baked to reach a temperature of 800 degrees Celsius, and after glazing, the oven is baked at a temperature of 1200 degrees Celsius. When the temperature is 200 degrees Celsius, the moldings are removed.

The molding according to claim 1, wherein the molding is a road block, a sidewalk block, or a fume pipe.

The method of claim 1, wherein the brick is made from a molding.
