Problems solved by technology
The known method of loading and transporting refractory materials for CDQ furnace masonry is the combination of electric hoists, elevators, and trolleys. However, during the masonry construction process, the transportation of refractory materials inside and outside the furnace restricts the construction progress and affects the construction cost. , and the transportation method is improper, easy to damage the refractory material
[0003] Therefore, there are above-mentioned inconveniences and problems in the known CDQ furnace masonry refractory loading and transportation method.

The invention provides a loading and transporting method of a dry quenching furnace constructing refractory material. The upper part of a dry quenching furnace is a prestorage section, the middle is an annular air channel and inclined air channel region, and the lower part is a cooling section. The method is characterized by comprising the following steps of: a, setting an external vertical transport mechanism outside the dry quenching furnace; b, setting a horizontal transportation mechanism connecting the inside and outside of the dry quenching furnace; and c, setting an internal vertical transport mechanism at the furnace mouth of the dry quenching furnace. The loading and transporting method of a dry quenching furnace constructing refractory material of the invention has the advantages of reasonable construction step design, easy operation, construction efficiency improvement, guarantee of refractory material transport quality, labor intensity reduction and construction cost reduction.
Description
technical field [0001] The invention relates to a construction method for kiln masonry, in particular to a method for feeding and transporting refractory materials for CDQ furnace masonry. Background technique [0002] In order to meet the requirements of national environmental protection, most domestic steel mills and coking plants have successively built large-volume dry coke quenching instead of wet coke quenching. The domestic CDQ furnace is a vertical tank with a circular cross-section, and the shell is made of steel plate and section steel. The inner lining is made of refractory material. According to the production capacity of the CDQ furnace, the weight of the inner lining refractory material is generally about 600-900 tons. The upper part of the CDQ furnace is the feed inlet of the pre-storage section, the middle is the ring air duct and the inclined air duct area, and the lower part is the cooling section. Two manholes of about 1m*1.5m are opened on the platform o...
