Embodiment Construction

[0011] Embodiments of the present invention: use suitable reduction or neutral roasting, sintering raw materials such as calcium, magnesium, barium oxide minerals, carbonated minerals or raw materials as main raw materials, and use raw coal or other carbonaceous raw materials with ash content less than 15% As ordinary carbonaceous raw materials, take 20 kg of main raw materials and 80 kg of ordinary carbonaceous raw materials; or take 50 kg of main raw materials and 50 kg of ordinary carbonaceous raw materials; or take 80 kg of main raw materials and 20 kg of ordinary carbonaceous raw materials; The percentage by weight of common carbonaceous raw materials accounting for the total weight of the mixture is controlled in the range of 20% to 80%: 80% to 20%, and the sum of the percentages by weight of the two kinds of raw materials accounting for the total weight of the mixture is 100%. Mix the powdery main raw material and the crushed ordinary carbonaceous raw material at room te...

Abstract

The production method of raw material carbon includes the following steps: using the raw material suitable for reduction or neutral calcination and sintering as main raw material, mixing the powder main raw material and broken general carbon raw material to obtain mixed material at normal temp. and calcining or sintering said mixed material in kiln with 823-1573 K temperature range so as to obtain the invented raw material carbon with a certain grain size. The heat quantity required for calcination or sintering mainly is provided by volatile matter discharged from carbon raw material in the mixed material and combustion of small fixed carbon.

Description

Technical field: [0001] The invention relates to a method for the production of raw carbon for use in the metallurgical and chemical industries. Background technique: [0002] At present, in some raw materials and fuel preparation and material preparation procedures in the existing metallurgical or chemical industry, it is often necessary to granulate, roast or sinter the powder and granular main raw materials suitable for reduction or neutral roasting and sintering to obtain the desired The raw materials with the required properties are then combined with carbonaceous raw materials such as coke for the next process to finally produce the required products. The characteristics of the existing raw material preparation and material preparation process are: a. During granulation, some raw materials that have no mechanical strength after roasting need to be added with binders; b. The roasting and sintering of the main raw materials require a set of kiln equipment And heat sourc...
