More particularly, the present invention relates to a method for curing in multi-layer stacking in a vertical furnace without causing briquette breakage.

練炭が生成する。 In conventional methods, charcoal briquettes are generally hardened by heating them in an oxidizing atmosphere at a temperature of about 200°C. Under these conditions, oxygen promotes a copolymerization reaction between the semi-coked coke and the binder (generally pitch), and calcination at this temperature results in a combination of carbon from the semi-coked material and carbon from the binder. Uniform briquettes are produced that make it difficult to tell what kind of briquettes they were made for.

ガス流で包囲する。 Conventionally, the curing by heating the briquettes is approximately 200%
The green briquettes are placed at a height of 30 to 45 °C on a moving grate or suitable rack moving through a tunnel furnace maintained at a temperature of 30 to 45 °C.
It is carried out by stacking it in layers of cm. In the furnace, the briquettes are surrounded by a gas stream containing 5 to 18% (by volume) of oxygen.

かの他の欠点を有している。 Besides layer height limitations, this technology has several other drawbacks.

に応じて約２時間（又はそれ以上）である。 First, the equipment is expensive and has a very high wear rate. Second, they have limited production capacity and occupy a large amount of floor space. Furthermore, the time required for processing is also about 2 hours (or more) depending on the size of the briquettes.

温度に２時間維持されていた。 In summary, traditional briquette hardening processes are carried out in tunnel or grate furnaces, in which the briquettes are not subjected to loads that would cause them to break and are not exposed to the risk of wear. For this purpose, it was heated to 200° C. and maintained at this temperature for 2 hours in the presence of a flow of air.

することが知られている。 On the other hand, hardening the briquettes in a vertical furnace in a state in which a large number of briquettes are stacked in layers (multilayer stacking state) is extremely effective in terms of productivity and floor space utilization. However, it is known that when briquettes are stacked, the briquettes may break due to the weight of other briquettes stacked on top.

にある。 That is, the object of the present invention is to provide a method for curing semi-formed coke briquettes containing pitch as a binder in a multilayer stacking state in a vertical furnace, in which the briquettes are heated in an inert atmosphere at a temperature of 300°C to 300°C.
An object of the present invention is to provide a method for curing semi-formed coke briquettes, which is characterized in that the treatment is carried out at 400°C for 35 to 150 minutes.
