Problems solved by technology
[0004] The technical problem to be solved by the present invention is that due to the masonry molding of the existing calcium carbide furnace, when there is a leak in the oven or roasting process, or when there is an abnormality in the production process, it is easy to cause abnormal situations such as the furnace hole burning through the furnace wall and gradually collapsing. The problem that caused the calcium carbide furnace to be unusable

Abstract
The invention relates to the technical field of calcium carbide furnaces, in particular to a calcium carbide furnace and a roasting method of the calcium carbide furnace. The calcium carbide furnace comprises a furnace bottom, a furnace wall and a furnace door. The furnace wall is built on the furnace bottom. The furnace door is arranged on the furnace wall, and the furnace door is integrally formed through silicon nitride pouring. According to the calcium carbide furnace, the furnace door is integrally poured through silicon nitride, compared with the layer-by-layer building mode of a furnacedoor of a traditional calcium carbide furnace, silicon nitride is combined with silicon carbide bricks, the furnace door of the calcium carbide furnace provided in the invention is not prone to melting of a furnace core, even if materials fall off at a discharging port due to operation problems, the overall pouring mode is adopted, small parts fall off, the rest of the furnace is still a whole, and the problems that mistakes are made due to the furnace drying process and the roasting process of the calcium carbide furnace, or exceptions occur in the production process, so abnormal conditionshappen, for example, the furnace core is melted or the furnace wall is collapsed gradually, then major potential safety hazards appear, and the calcium carbide furnace cannot be used anymore are solved.
Description
technical field [0001] The invention relates to the technical field of calcium carbide furnaces, in particular to a calcium carbide furnace and a roasting method for the calcium carbide furnace. Background technique [0002] The furnace door of the traditional calcium carbide furnace is built by layer-by-layer masonry. The furnace door is made of silicon nitride combined with silicon carbide bricks, and the overall thickness of the masonry is 1 meter. However, under this kind of masonry method, if there are mistakes in the oven and roasting process, or if there is an abnormality in the production process, it is easy to cause abnormal conditions such as the furnace eye burns through the furnace wall and gradually collapses, which in turn leads to the problem that the calcium carbide furnace cannot continue to be used. Moreover, the traditional calcium carbide furnace has a thicker overall masonry and takes up a lot of space, resulting in a smaller furnace, and the raw materia...
