Fire Clay Bricks
Clay bricks, also known as sintered bricks, are man-made small blocks used in construction. Clay bricks take clay (including shale, coal gangue and other powder) as the main raw material, and are made by mud treatment, molding, drying and roasting, with solid and hollow respectively.
Coke ovens
A furnace, usually constructed of refractory bricks and refractory blocks, used to convert coal to produce coke. A kiln that produces coke from coal.
Clay brick is made of clay (including shale, coal gangue and other powder) as the main raw material, through mud treatment, molding, drying and roasting. The size of ordinary brick is 240 mm ×115 mm ×53 mm, according to the size of compressive strength (Newton/square mm, N/mm2) is divided into MU30, MU25, MU20, MU15, MU10, MU7.5 these six strength grades. The Al2O3 content of clay bricks in China is generally more than 40%, and the Fe2O3 content is less than 2.0 ~ 2.5%. The clinker is 65 ~ 85% and the combined clay is 35 ~ 15%. The pulverized bonded clay is mixed with the fine clinker, and then the granular clinker is prepared into semi-dry mud, which is formed under high pressure and fired at about 1400℃. Clay brick is weakly acidic at high temperature, and its ability to resist alkaline slag erosion is slightly poor, but it is enhanced with the increase of Al2O3 content. The thermal stability is better than that of silicon brick and magnesium brick (see magnesium brick).
